from Wikipedia

The Manila Electric Company, also known as Meralco (/mɜːrɑːlk/, Tagalog: [mɛˈɾalkɔ], stylized in uppercase), is an electric power distribution company in the Philippines. It is Metro Manila's only electric power distributor and holds the power distribution franchise for 39 cities and 72 municipalities, including the whole of Metro Manila and the exurbs that form Mega Manila.

Key Information

The name "Meralco" is an acronym for Manila Electric Railroad and Light Company, which was the company's official name until 1919.

History

[edit]

La Electricista

[edit]

Organized in 1891 and beginning operations in late 1900, La Electricista was the first electric company to provide electricity to Manila towards the close of the Spanish era. La Electricista had built a central power plant on Calle San Sebastián (now Hidalgo Street[1][2]) in Quiapo, Manila.[3] On January 17, 1895, its streetlights were turned on for the first time and by 1903, it had about 3,000 electric light customers.

Founding of the Manila "Electricity", "Railroad" and "Lighting" Company (MERaLCo)

[edit]

On October 20, 1902, under the American Insular Government, the Second Philippine Commission began accepting bids to operate Manila's electric company, and by extension, providing public lighting to the city and its suburbs. Detroit entrepreneur Charles M. Swift was the sole bidder and on March 24, 1903, was granted the original basic franchise of the Manila Electric Company.[4] March 24 thus is marked annually as the company's anniversary.

The Manila Electric Company acquired both La Electricista and the Compañía de los Tranvías de Filipinas, a firm that ran Manila's horse-drawn tramways which was founded in 1882.[5] Construction on the railed tramway began that same year. In addition to acquiring La Electricista's Calle San Sebastián power plant, the company built its own turbine rotated by water steam generating electricity plant on Isla de Provisor (later becoming the Manila Thermal Power Plant), which fuelled the railed tram system and eventually also provided the electric service. By 1906, the Manila Suburb Railway were founded and later merged with the Manila Electric Company. Forming the Manila Electric, Railway and Lighting Company. The name Manila Electricity, Lighting and Railroad Company (MELARCo) was also considered.[citation needed]

Manila Suburban Railways Company

[edit]

Swift was awarded another franchise in 1906 to operate a 9.8 kilometres (6.1 mi) extension line from Paco to Fort McKinley and Pasig and founded the Manila Suburban Railway to operate this franchise.[4] In 1919 this company merged with the Manila Electric Company.[4] This extension was one of the most profitable of MERALCO's lines.[4]

By the 1920, MERALCO invested on transportation and owned a 170-strong fleet of streetcars, before switching over to buses later in that decade.

The company operated 52-miles of trams until World War II. The equipment and tracks of the system was severely damaged during the war and had to be removed.[6]

Power generation and distribution

[edit]

By 1915, electricity generation and distribution became the main MERALCO's main income generator, overtaking its public transportation operations in terms of revenue. In 1919, it changed its official name to Manila Electric Company. By 1920, the company's power capacity had grown to 45 million kWh.

In 1925, MERALCO was acquired by the utility holding company Associated Gas and Electric, which had begun a massive expansion throughout the United States and Canada. With AGECO's financial backing, MERALCO began acquiring a number of existing utility companies in the Philippines, enabling the company to expand beyond Manila.

By 1930, MERALCO had completed construction of the Philippine's first hydroelectric power plant, the 23MW Botocan Hydro Station.[7] At the time, this plant was one of the largest engineering projects in Asia[citation needed] and constituted the largest single private capital investment in the Philippines.[citation needed] The additional capacity allowed the company to begin hooking up customers throughout the metropolitan area.

To drive demand for more power, MERALCO also opened a retail store in order to sell electric home appliances.[citation needed]

World War II

[edit]

During the Second World War, the Japanese occupying forces forcibly transferred all of MERALCO's assets and holdings to the Japanese-controlled Taiwan Power Company.

Postwar

[edit]

By war's end, most of the former Meralco facilities had been destroyed. AGECO was reorganized as General Public Utilities Corporation or GPU in 1946. MERALCO's autobus franchise was sold to Halili Transport.

Acquisition by the López group

[edit]

In 1962, Eugenio López, Sr. of the influential López family of Iloilo put together Meralco Securities Corporation (MSC), which acquired MERALCO, making it wholly Filipino-owned.[8] During 1962-72, he increased MERALCO's power generating capacity by five times with the building of additional power stations in the Manila area with two more planned in Rizal Province.[9]

The Meralco Building, designed by National Artist of the Philippines for Architecture José María Zaragoza, was built during this period. The Meralco Theater within it was inaugurated shortly thereafter, in March 1969.[10]

Martial law and Romualdez takeover

[edit]

In September 1972, President Ferdinand Marcos, who had begun feuding with the Lópezes,[11] declared Martial Law, acquiring and consolidating power and effectively extending his beyond the constitutional term limit which would have forced him to step down in 1973.[12][13] A few weeks later in November 1972, he issued Presidential Decree № 40, which nationalized the country's electric generation and transmission. A few more weeks after that, Marcos had López' son and namesake, Eugenio "Geny" López, Jr. arrested without formal charges, claiming that the younger López had been involved in an alleged assassination attempt against him.[11]

Geny's arrest became a bargaining chip which eventually compelled the Lopezes to sell their controlling share of Meralco Securities Corporation to Marcos' associates late in 1973.[11] Ownership of Meralco Securities Corporation was placed under a newly created shell company called the Meralco Foundation, Inc., controlled by Marcos' brother-in-law Benjamin Romuáldez,[11] which made a downpayment of about $1,500 for a "very minimal" total sale price of about $28 million (200 million pesos at the prevailing rate). Installment payments were supposed to be due starting two years later.[14]

The Meralco Foundation takeover was immediately followed by a 100% increase in electric rates, with continuous increases throughout Romuáldez's management.[15] A rate adjustment clause, which allowed MERALCO to adjust its rates depending on crude oil increase or higher dollar exchange rates, was also introduced.[15]

In 1977, MSC was renamed First Philippine Holdings Corporation.[8]

By 1978, all of the Philippines' major power plants were owned and operated by Napocor, including the Metro Manila plants that MERALCO had built beforehand in the 1960s.[citation needed] By the end of the Martial Law period in 1981, MERALCO expanded even further into Cavite and western parts of Laguna, Rizal and Quezon provinces, as well as parts of southern Bulacan.[citation needed]

Meralco Foundation's control of MERALCO lasted until the People Power Revolution in February 1986 when it defaulted on its payments under the terms of the original turnover of shares in 1973,[16] although it took a five-year period before the shares were eventually reverted to the Lópezes in 1991.[16]

After martial law

[edit]

President Corazon Aquino reverted company ownership to the López Group.[citation needed] She also enacted an executive order that allowed the company to directly compete with Napocor.[17]

On March 18, 1989, MERALCO unveiled its new and current corporate logo.[18]

In 1990, MERALCO acquired the electric facilities and other assets of the Communications and Electric Development Authority, one of two companies that distributed power in Cavite Province for much of the 1970s and 80s.[19]

Entry of First Pacific and JG Summit groups

[edit]

Between 2009 and 2012, the López Group would reduce its 33.4% holdings in MERALCO by selling most of its shares to the First Pacific Group.[20][21][22] By 2012, the López Group's holdings in MERALCO would be reduced to 3.95%.[23]

The First Pacific Group, through Beacon Electric Asset Holdings Inc. and Metro Pacific Investment Corporation, currently holds the majority share in MERALCO,[21] followed by the Gokongwei Family's JG Summit Group. (See further: ownership )

Early renewal initiatives during the 16th Congress

[edit]

In 2014 and 2015, MERALCO requested the 16th Congress to tackle the extension of its franchise early, although its renewal was not due until six years later, in 2020.

Franchise renewal

[edit]

On April 11, 2025, President Bongbong Marcos signed Republic Act No. 12146 which renewed MERALCO's franchise for another 25 years from its expiration in 2028.[24][25][26][27]

Controversies

[edit]

2008 legislative investigation on high power rates

[edit]

Meralco is facing a Philippine legislative inquiry/investigation for alleged excessive pricing.[28] The government has considered a plan to take over Meralco, to reduce electricity bills. Meralco and National Transmission Corporation (TransCo) blamed each other for the high power rates.[29] Meralco also blames high power generation costs, high transmission costs and government taxes imposed on the electricity sector from power generation to distribution. Government Service Insurance System (GSIS) President Winston García, however, blamed Meralco's inefficiency, its "bloated bureaucracy" and its sourcing of power from independent power producers (IPPs) also owned by the López Family, and the need to amend the Electric Power Industry Reform Act (EPIRA) of 2001. Oscar López said that if the GSIS would buy the Meralco shares, they must buy in whole cash, while many businessmen also said that taking over Meralco is not the way to reduce electrical price, which depends on the national government and the President. The issue was also seen as a purposeful diversion from the then-ongoing ZTE NBN scandal and other government issues.[30] A perceived lack of general understanding regarding the issue of system loss, inherent in the business of utilities prompted Meralco's former holding company, First Philippine Holdings, to issue advertisements explaining systems loss.

Syndicated estafa and bribery case

[edit]

The Department of Justice (Philippines) filed syndicated (fraud) charges against Meralco in its August 22, 2008 31-page resolution, filed with the Pasig Regional Trial Court. The May 29 National Association of Electricity Consumers for Reform (Nasecore) complaint accused Meralco of "illegally declaring as income ₱889 million in consumers' money, which represents interest from meter and bill deposits consumers had been paying since 1995."[31] No bail was recommended for all the accused, 2006 officers of Meralco, to wit: Meralco chairman and CEO Manuel Lopez, executive vice president and chief financial officer Daniel Tagaza, first Vice-resident and treasurer Rafael Andrada, vice president and corporate auditor and compliance officer Helen De Guzman, vice president and assistant comptroller Antonio Valera, and senior assistant vice president and assistant treasurer Manolo Fernando; 2006 Meralco directors Arthur Defensor Jr., Gregory Domingo, Octavio Victor Espiritu, Christian Monsod, Federico Puno, Washington Sycip, Emilio Vicens, Francisco Viray and former Prime Minister Cesar Virata.

Nasecore's complaint accusing Meralco of "illegally declaring as income 889 million pesos in consumers' money, which represents interest from meter and bill deposits consumers had been paying since 1995," was immediately refuted by the accused company as the alleged ₱889 million only stemmed from a generally accepted accounting principle of reversing Meralco's earlier provision for meter deposit interests which, earlier set at 10% per annum was deemed too high and was set to the recommended 6%.[32] Meralco also questioned how a syndicated estafa case can arise when it has already announced and committed that it will be refunding to customers who paid meter deposit principals plus interest months ahead of the ERC prescribed schedule and has allocated enough funds for the said refund.

Meralco is also involved in the GSIS-Meralco bribery case.[33]

Dismissal of syndicated estafa case

[edit]

On October 6, 2008, the Pasig Regional Trial Court Branch 71 dismissed the syndicated estafa case filed against the Meralco board of directors, for the prosecution failed to establish all the elements of syndicated estafa.

Presiding Judge Franco Falcon, pointed out in the ruling that the board is not the kind described by the law as being formed to perpetrate an illegal act for the board of directors were elected by stockholders. The court explained, "Therefore, the accused can never be charged of taking part in the commission of syndicated estafa not only because they are not part of a syndicate as contemplated by law in PD 1689, but more so, because there was absolutely no estafa committed."

According to Philippine law, to constitute syndicated estafa, the subject money or property must be received by the offenders. The money represents the accrued interests on the bill and meter deposits, which were paid by Meralco customers, not directly to the board, but to the various Meralco business centers where the customers transacted. Meralco expressed elation over the dismissal.[34]

Judiciary's decision on 1999 disconnection incident

[edit]

A complaint was filed by Lucy Yu against Meralco which, on December 9, 1999, its representatives, forcibly entering her office at the New Supersonic Industrial Corp. in Valenzuela, shut off the electricity in the factory and Yu's residence.

The Court of Appeals later ruled that Meralco violated the law when it cut off the electric supply of a consumer without notice; the decision later upheld by the Supreme Court in late June 2023, with Yu being entitled to ₱150,000 in damages. The court said that a written notice must be given to the consumer at least 48 hours prior to Meralco's disconnection of its electric service on grounds cited under Section 4(a) of Republic Act No. 7832; in that case, a consumer's right to due process was violated.

Spokesperson Joe Zaldarriaga, in a statement, said that Meralco will respect and abide by the said decision; however, he said that the incident occurred when Meralco was already implementing a policy of serving prior disconnection notice.[35]

Allocation of the 2.4 GHz ISM band

[edit]

The 2.4 GHz band is mostly used by Wi-Fi and Bluetooth. In 1993, the National Telecommunications Commission allocated the 2.4 GHz band for the exclusive use by Meralco in Metro Manila, Central Luzon, and Calabarzon for the operation of their Supervisory Control and Data Access (SCADA) system which controls and monitors Meralco’s substations.[36] This has made the use of the 2.4 GHz band in the Philippines illegal, in spite of the International Telecommunication Union declaring the 2.4 GHz band as an ISM unlicensed band.[37]

On September 12, 2003, the NTC issued Memorandum Circular No. 09-09-2003, which lifted the ban on the 2.4 GHz band.[38]

Meralco serves Metro Manila, where it is the sole electricity distributor, as well as some nearby provinces, like Bulacan, Cavite, Laguna, Batangas, Rizal, Quezon. Bulacan, Cavite, and Rizal are solely served by Meralco, but on some provinces, it only serves some parts, like in Laguna, Batangas, and Quezon, where most or some areas are served by electric cooperatives. In Laguna and Quezon, most part of those provinces are served by the company, but other areas, mostly rural municipalities, are served by electric cooperatives. In Batangas, only Santo Tomas, the First Philippine Industrial Park and First Industrial Township SEZ both in Tanauan, Batangas City, San Pascual and parts of Laurel (Barangays of Niyugan and Dayap Itaas) and Calaca (parts of Barangay Cahil) which facing Tagaytay–Nasugbu Highway are served by Meralco, and the rest of the province are franchise areas of electric cooperatives. In Pampanga, some barangays in Candaba are served by the company.

The Manila Electric Company (Meralco) is the largest electric distribution utility in the , responsible for delivering electricity to over 8 million residential, commercial, and industrial customers across a franchise area of approximately 9,685 square kilometers encompassing 39 cities and 72 municipalities in and nearby provinces. Established on March 14, 1903, as the Manila Electric Railroad and Light Company to supply electric light, power, and street railway services to and its suburbs, Meralco evolved into its current form focused on power distribution following during and subsequent reprivatization in 1991. Its longevity—marking 122 years of operation as of 2025—has positioned it as a cornerstone of the Philippine economy, powering urban centers and supporting industrial growth amid the archipelago's chronic energy supply challenges. Majority-owned by conglomerates including Metro Pacific Investments Corporation (47.5%) and JG Summit Holdings, Inc. (26.4%), Meralco operates under a regulated framework where distribution charges are capped by the Energy Regulatory Commission, while generation and transmission costs—often the bulk of consumer bills—are passed through directly, leading to frequent public debates over levels tied to volatile wholesale prices and fuel dependencies. Notable achievements include maintaining high system reliability, with initiatives in digital service platforms earning the 2024 ASEAN Enterprise Innovation Award, and sustainability efforts recognized in global rankings like the Global 2000. Controversies have centered on perceived high rates and past disputes, such as the resolved GSIS share sale case, underscoring tensions between regulated monopoly efficiencies and consumer cost sensitivities in a supply-constrained market.

History

Early Foundations and Incorporation

The Manila Electric Railroad and Light Company (MERALCO), predecessor to the modern Manila Electric Company, was formally incorporated on March 14, 1903, during the American colonial administration of the Philippines. This establishment followed the U.S. acquisition of the Philippines after the Spanish-American War in 1898, as part of efforts to modernize urban infrastructure in Manila with electric-powered systems. Prior to MERALCO, limited electric service had been introduced by La Electricista, founded in 1892, which supplied power to parts of the city but lacked capacity for broader expansion including rail transit. American businessman Charles M. Swift, granted a 50-year franchise by Philippine authorities, spearheaded the company's formation to address the need for reliable electric street railway services and lighting in and its suburbs. The franchise authorized the construction and operation of an electric tramway network alongside the generation and distribution of and power, integrating transportation and services to support urban growth. Swift's initiative capitalized on emerging electric technologies, aiming to replace outdated horse-drawn systems with efficient, electrified alternatives amid 's reconstruction. Early operations commenced shortly after incorporation, with tramway construction beginning in 1903 and the acquisition of La Electricista in to consolidate existing power infrastructure. By 1906, MERALCO had achieved an annual power output capacity of 8 million kilowatt-hours, demonstrating rapid scaling to meet demand for both residential lighting and commercial rail services. These foundations positioned MERALCO as the primary in the region, laying the groundwork for its dominance in power distribution while initially balancing dual mandates in rail and .

Pre-World War II Expansion

Following its establishment, Meralco acquired the existing La Electricista utility in 1904, integrating approximately 3,000 customers and street lighting infrastructure into its operations. By 1906, the company's annual power output had reached 8 million kWh, supporting expanded electric light and power services in Manila and its suburbs. In 1919, the firm officially adopted the name Manila Electric Company, though it continued to prioritize both electricity distribution and rail-based transportation. Power capacity grew to 45 million kWh by 1920, driven by increasing demand in urban areas. During the 1920s, Meralco expanded its public transportation arm, assembling a fleet of 170 streetcars to serve 's growing population before shifting toward bus services later in the decade. The 1925 acquisition by the American holding company Associated Gas & Electric Co. (AGECO) provided capital for broader infrastructure development, including the purchase of additional utilities across the Philippines and the deployment of diesel generators to extend distribution networks beyond Manila's city center in the late 1920s. A key project was the 1930 completion of the Botocan Falls Hydroelectric Station in Laguna province, which boosted regional power supply and reliability for metro Manila. By 1941, as Japanese forces approached, Meralco's power capacity had scaled to 184 million kWh annually, reflecting sustained investment in generation and transmission assets.

World War II Destruction and Postwar Reconstruction

During , Japanese occupying forces seized control of Meralco's assets, transferring them to the Japanese-controlled . The Battle of from February to inflicted catastrophic damage on the city's , including Meralco's extensive tranvia (streetcar) network spanning 52 miles of tracks and equipment, as well as power generation and distribution facilities. By the war's end in 1945, most of Meralco's operations had been rendered inoperable, mirroring the broader devastation of , where over 100,000 civilians perished and urban structures were largely obliterated. Postwar reconstruction prioritized restoring electric service amid the Philippines' independence and economic recovery. By 1947, Meralco had rehabilitated its power distribution network, achieving capacity exceeding prewar levels and supporting initial rehabilitation efforts across Metro Manila. The tranvia system, deemed beyond repair, was abandoned, with rails removed from streets, allowing Meralco to divest from transportation; in 1948, remaining bus operations were sold to Fortunato Halili, refocusing the company exclusively on electricity. In 1950, Meralco initiated a five-year, ₱45 million expansion program to rebuild and augment power plants, distribution lines, and overall capacity, addressing surging demand from postwar industrialization. By the early 1950s, service was fully restored to 39 towns and cities in the metropolitan area, serving more than 200,000 customers and powering much of the nation's early reconstruction. This shift solidified Meralco's role as the primary in the region, under continued American ownership until later decades.

López Group Acquisition and Growth

In January 1962, Meralco Securities Corporation (MSC), assembled by Filipino entrepreneur Eugenio López Sr. and a consortium of local investors, purchased the Manila Electric Company from its American parent, General Public Utilities Company, transitioning ownership to full Filipino control for the first time. The López Group's stewardship catalyzed significant operational expansion throughout the 1960s. Meralco built a new power plant roughly every 18 months, boosting its generating capacity from 300,000 kilowatts to 1.5 million kilowatts—a fivefold increase—within a decade to meet surging demand in Metro Manila. Financing for this development relied on Meralco's robust international credit profile, secured through private capital markets without government backing or subsidies, which supported competitive pricing and positioned the among those offering the world's lowest rates. By 1969, these efforts elevated Meralco to the ' largest corporation, with assets surpassing one billion pesos; its valuation climbed further to 2.8 billion pesos by 1972, reflecting sustained infrastructure investments and customer base growth.

Martial Law Period and Romualdez Influence

During the declaration of martial law on September 23, 1972, President Ferdinand Marcos targeted assets owned by political opponents, including the Lopez family's control of Meralco through Meralco Securities Corporation (MSC). Eugenio Lopez Sr., chairman of MSC and a vocal Marcos critic, was detained shortly after, leading to the government's sequestration of the company's shares. Benjamin "Kokoy" Romualdez, Marcos's brother-in-law and a key crony, organized the Meralco Foundation, Inc. (MFI) with nominal initial capital and facilitated the transfer of Lopez-held MSC shares to this entity, effectively placing Meralco under regime-aligned control. Government officials, including , later asserted the transfer constituted a legal sale in 1973 to prevent Meralco's , supported by letters from Lopez offering the shares amid financial strains from prior expansion and rate disputes. Critics, however, contended the transaction occurred under coercion, given Lopez's detention and the environment suppressing dissent and property rights. Romualdez, as MFI controller, wielded substantial influence over operations, aligning Meralco with national energy policies that nationalized generation assets—transferring them to the by 1975—while retaining the company as a distribution monopoly in and surrounding areas. Under this administration, Meralco shifted focus to infrastructure rehabilitation and expansion, extending service to parts of , Laguna, Rizal, and by 1981, coinciding with martial law's formal end. Rate adjustments and investments proceeded amid government oversight, though efficiency suffered from and politicized management, as evidenced by later PCGG probes into ill-gotten wealth claims against Romualdez-linked entities. The period marked a transition from private enterprise to state-influenced utility, with Romualdez's role emblematic of broader under Marcos.

Post-Martial Law Ownership Shifts

Following the in February 1986, President Corazon Aquino's administration restored partial ownership of Meralco to the López family through (FPHC), the successor to Meralco Securities Corporation, ending the government-controlled Meralco Foundation's oversight that had persisted since 1974. However, the returned stake was limited to approximately 15.2 percent, far short of the pre-Martial Law majority held by the Lopezes, as government entities and other shareholders retained significant portions amid disputes over compensation for seized assets. By 1991, FPHC had incrementally reclaimed shares to reach about 16 percent, reflecting a gradual but incomplete recovery process constrained by financial and legal hurdles from the prior regime's interventions. In the mid-2000s, FPHC pursued aggressive stake-building to regain influence, acquiring additional shares including a 9 percent block from Spain's Union Fenosa in July for an undisclosed amount, elevating its holdings to 33.4 percent and securing board control. This period coincided with corporate turbulence, including the 2008 GSIS-Meralco bribery scandal, where (GSIS) attempted to purchase shares to challenge FPHC's dominance but faced legal blocks and corruption allegations against its leadership, ultimately failing to alter the board composition significantly. The instability, coupled with Meralco's rising debt and regulatory pressures, prompted the family to divest, signaling a strategic retreat from the utility amid broader portfolio shifts. Major ownership transitions accelerated from 2009, as FPHC sold a 20 percent stake to Metro Pacific Investments Corporation (MPIC), controlled by Manuel V. Pangilinan's First Pacific Company, for approximately P27.2 billion, followed by additional tranches including 6.6 percent in March 2010 for P22.4 billion and further blocks through 2012, reducing FPHC's position to 3.95 percent. These sales transferred effective control to the Pangilinan group, which consolidated 48 percent via entities like Beacon Electric Holdings by 2012, prioritizing infrastructure synergies with . Concurrently, (SMC) under acquired a 27 percent stake amid the flux, but divested it in December 2013 to of the Gokongwei family for P72 billion (about $1.65 billion), marking JG Summit's entry as a key and diversifying ownership away from López dominance.

Modern Era Reforms and Franchise Renewal

In the 2000s and 2010s, Meralco pursued operational reforms aligned with the Electric Power Industry Reform Act (EPIRA) of 2001, which emphasized competitive procurement and efficiency in power distribution to reduce costs and improve reliability. These included adopting performance-based regulation by the Energy Regulatory Commission (ERC), leading to investments in infrastructure upgrades and loss reduction programs that lowered distribution losses from over 10% in the early to around 6% by the mid-. Further enhancements involved management restructuring in 2023 to streamline operations and boost service delivery, alongside digital initiatives like enhanced billing platforms that facilitated over 25 billion in collections in 2024 through improved efficiency and customer engagement. A key component of modern reforms has been the push toward technologies, exemplified by Meralco's plan to deploy 11 million smart meters over the next decade starting in 2025, enabling real-time consumption monitoring, capabilities, and reduced non-technical losses. These measures aim to modernize the distribution system amid rising demand, with commitments to cybersecurity enhancements and energy efficiency audits under the Energy Efficiency and Conservation Act. However, compliance with EPIRA's competitive selection processes for agreements has faced criticism, including allegations of favoring affiliates and exceeding the 50% sourcing limit from related parties, prompting ERC interventions and consumer group complaints. Meralco's franchise renewal process unfolded amid ongoing regulatory scrutiny, including a June 2022 ERC order mandating refunds exceeding 40 billion to consumers for over-recoveries between July 2015 and June 2022. The existing franchise, granted under Republic Act No. 7832 and set to expire in 2028, prompted legislative action with approval on final reading November 6, 2024 (186-7-4 vote), followed by February 4, 2025. President Jr. signed Republic Act No. 12146 on April 11, 2025, extending the franchise for 25 years to 2053 and authorizing continued operation of distribution systems serving approximately 7.8 million customers in and nearby provinces. The renewal includes Meralco's pledges for accelerated capital expenditures in long-term projects, such as substation expansions, support, and renewable integration, to enhance supply security and operational resilience. hearings in November 2024 highlighted concerns over pricing transparency and , yet the extension proceeded, with the company affirming alignment with DOE guidelines on competitive bidding for future contracts. Critics, including consumer advocates, argued for stricter amendments to curb potential monopolistic practices, reflecting persistent debates on balancing investor confidence with in the reformed sector.

Electrification within the franchise area reaches near universality, with coverage exceeding 99.9% as reported in recent programs. This extensive reach positions Meralco as the primary distributor for a significant share of the ' urban and peri-urban electricity needs.

Power Distribution Infrastructure and Technology


Meralco maintains a vast distribution network spanning over 21,200 kilometers of electric circuits, supported by 149 substations and approximately 249,000 distribution transformers to serve its franchise area in and surrounding provinces. The system delivers electricity from transmission grids operated by the National Grid Corporation of the , stepping down voltages through subtransmission and distribution levels to end-users.
The majority of distribution lines are overhead, constructed primarily on wooden, , or poles, though Meralco is systematically replacing wooden poles with more durable alternatives to enhance resilience against . In 2024, the company replaced 7,120 wooden poles as part of a broader initiative to phase them out entirely by 2033. To further bolster grid reliability, Meralco plans to install 1,500 circuit kilometers of underground lines by 2030, prioritizing high-risk and urban areas prone to typhoons and flooding. Substations form the core of Meralco's , with recent expansions and upgrades addressing growing and capacity constraints; for instance, in 2025, the DP substation's transformer capacity was increased from 100 MVA to 300 MVA to support load growth in province. Other enhancements include the addition of 115-kV circuit breakers at the Abubot Substation in and the commissioning of the Pamplona Uno 115-34.5 kV gas-insulated substation in City, reflecting investments totaling P1.9 billion in upgrades during the year. These modifications incorporate elevated structures and hardened components to mitigate risks from .

Key implementations include partnerships for distributed energy resource management and integration, with a 2025 collaboration with enhancing smart metering and grid analytics across the network. These technologies enable real-time data processing, , and improved , contributing to higher system reliability amid increasing demands.

Energy Supply Chain and Subsidiaries

Meralco procures primarily through long-term power supply agreements (PSAs) with independent power producers (IPPs) and supplemental purchases from the Wholesale (WESM), ensuring supply for its franchise area covering over 9 million customers as of 2024. The sources feeding these agreements are dominated by coal-fired , with operators such as affiliates (e.g., Mariveles Power Corp. and Masinloc Power Co. Ltd.) and GNPower Dinginin featuring prominently in recent competitive selection processes (CSPs); for instance, a 1,200 MW PSA with South Premiere Power Corporation was filed in 2024. and renewables constitute smaller shares, though Meralco has pursued diversification via CSPs approving PSAs with entities like San Miguel Global Power (SMGP) and ACEN in 2025, alongside extensions for First Gen Corp. supplies. To mitigate reliance on external IPPs and integrate upstream operations, Meralco established Meralco PowerGen (MGen) as its wholly-owned generation arm in 2014, targeting a diversified portfolio of 3,000 MW capacity by developing baseload, mid-merit, and renewable assets. MGen operates facilities including stakes in plants and solar projects via subsidiaries like MGreen Corp., which closed a US$600 million investment for the Terra Solar project in 2025; it also holds interests in Global Power (GBPC) for and renewables. This supports Meralco's supply security, with MGen contributing to PSAs such as a 200 MW bid cleared by the Department of in October 2025 involving AboitizPower and SMGP gas plants. Supporting subsidiaries enhance the supply chain's efficiency: Meralco Industrial Engineering Services Corp. (MIESCOR) provides electromechanical contracting for and transmission , while Meralco Services Corp. (MSERV) delivers after-the-meter solutions, including demand-side optimization to balance grid loads. Meralco also holds a 65% stake in Electric Distribution Corporation (CEDC), which manages distribution in the Clark Freeport Zone and sources power via dedicated PSAs, such as a three-year green supply deal with Citicore in 2025. These entities collectively address transmission handoffs from the National Grid Corporation of the (NGCP) and enable Meralco's transition toward renewables, targeting 1,000 MW from MGen by 2030 despite coal's cost-competitiveness in current PSAs.

Financial Performance

Meralco's consolidated revenues demonstrated resilient growth amid economic recovery and rising energy demand in the . In 2024, revenues reached 470.4 billion, marking a 6% increase from 443.6 billion in 2023, fueled by higher distribution volumes and expanded contributions from subsidiaries in power generation and retail supply. This followed a pattern of post-pandemic rebound, with annual revenue expansions averaging around 5-6% in recent years, supported by steady customer base growth in its franchise area and regulatory-approved rate adjustments. Profitability trends have outpaced revenue growth, with core —a metric excluding one-time gains—rising sharply to PHP 45.1 billion in 2024, a 22% year-over-year increase from approximately PHP 37 billion in 2023. This enhancement stemmed from operational efficiencies, stronger margins in the generation segment via subsidiaries like Meralco PowerGen, and favorable supply contracts that mitigated fuel cost volatility. Reported also climbed 21% to PHP 45.9 billion in 2024, reflecting robust underlying performance despite regulatory caps on distribution rates. Extending into 2025, the upward trajectory persisted, with consolidated core for the first half totaling 25.5 billion, up 10% from 23.2 billion in the first half of , driven by sustained volume growth and contributions from integrated operations. Company executives projected full-year core approaching 50 billion, underscoring profitability resilience amid inflationary pressures and dynamics in the power sector. Overall, these trends highlight Meralco's strategic diversification beyond pure distribution, enhancing earnings stability through .

Capital Investments and Efficiency Metrics

Meralco's capital expenditures in 2023 amounted to approximately 24.8 billion, with allocations primarily for additions to utility plants, generation assets, and distribution infrastructure, including 20.2 billion specifically for the distribution network to support new connections and asset renewals. In 2024, capex rose to 44.7 billion, a 52% increase from the prior year, driven by investments in new customer connections, asset renewals, substation upgrades, pole replacements (12,012 poles), and grid modernization initiatives such as and storm-hardening measures. For 2025, Meralco allocated 25 billion, with about 60% directed toward network enhancements including smart grids, underground lines, and resiliency projects to mitigate impacts. Long-term plans include 101 billion through 2030 for modernizing generation and distribution infrastructure, expanding renewable energy capacity to 1,500 MW attributable by that year, and deploying 11 million smart meters over a decade starting in 2025. These investments have contributed to by reducing outage durations and frequencies, as evidenced by progressive improvements in reliability indices. Meralco achieved its best-ever performance in 2024 for both the System Average Interruption Duration Index (SAIDI) and , attributing gains to capex-funded upgrades like conductor replacements and substation , which minimized downtime and maintenance costs.

Regulatory Framework

Franchise History and 2025 Renewal

The Manila Electric Company (Meralco) traces its origins to the establishment of the Manila Electric Railroad and Light Company on March 14, 1903, initially focused on operating electric streetcars and providing electric lighting in Manila. On March 24, 1903, American entrepreneur Charles M. Swift secured the original legislative franchise to construct and operate an electric railway and lighting system, marking the beginning of organized power distribution in the Philippines under American colonial administration. This early franchise evolved as the company expanded its scope from tram services to broader electricity generation and distribution, adapting to post-independence needs and nationalization efforts in the mid-20th century. By the 1960s and 1970s, Meralco had grown significantly, becoming the ' first billion-peso corporation in amid rapid in its service area. The company's franchise underwent periodic renewals and amendments to reflect changing regulatory landscapes, including government interventions during the era that temporarily altered ownership structures. In , enacted Republic Act No. 9209, granting Meralco a fresh 25-year legislative franchise effective from its enactment, authorizing the , operation, and of an electric distribution to serve end-users in and surrounding provinces covering over 9,685 square kilometers. This franchise, set to expire in June 2028, positioned Meralco as the dominant distributor serving approximately 7.1 million customers, representing about 55% of the nation's total electricity consumption despite covering only 3% of the land area. Anticipating the 2028 expiration, legislative efforts for renewal commenced in 2024. The approved House Bill 10926 on third reading on November 6, 2024, with 186 affirmative votes, seven against, and four abstentions, proposing a 25-year extension to sustain investments in grid reliability and expansion. The followed suit, passing the measure on February 4, 2025, incorporating provisions for enhanced regulatory compliance, including stricter reporting on service quality and environmental standards. President Ferdinand R. Marcos Jr. signed Republic Act No. 12146 into law on April 11, 2025, renewing the franchise for another 25 years until approximately 2053, subject to constitutional and regulatory oversight by the Energy Regulatory Commission (ERC). The 2025 renewal emphasizes long-term infrastructure modernization, enabling Meralco to secure over 2 gigawatts of additional contracts and pursue grid enhancements amid rising demand. Proponents argued that continuity would prevent service disruptions and support in the franchise area, while critics highlighted ongoing concerns over rate levels, though the mandates ERC approval for any adjustments. Meralco's leadership viewed the extension as a mandate to prioritize reliable, affordable, and delivery, building on its historical role in powering the ' premier urban and industrial hub.

Rate-Setting Mechanisms and ERC Oversight

The rates charged by Manila Electric Company (Meralco) for distribution are determined through a Performance-Based (PBR) framework, which replaced the earlier Rate-of-Return on Rate Base (RORB) methodology and emphasizes incentives for , service quality, and cost control. Under PBR, Meralco's maximum allowable revenues are capped via periodic rate resets, calculated based on projected efficient costs, allowable returns, and performance targets over regulatory periods typically spanning five years. The Energy Regulatory Commission (ERC) exercises primary oversight by reviewing and approving Meralco's rate applications, ensuring compliance with the Electric Power Industry Reform Act (EPIRA) of 2001 and associated rules. In October 2025, the ERC finalized the Rationalized Rules for Setting Distribution Wheeling Rates (RRDWR), adopting a price-cap mechanism that limits distribution, supply, and metering charges to levels reflecting prudent costs, reliability standards, and incentives for improvements in service metrics like outage duration and voltage quality. This framework mandates Meralco to submit detailed annual revenue requirement (ARR) proposals, such as the P393 billion projected for its fifth regulatory period, which the ERC scrutinizes for reasonableness before granting provisional or final approval. ERC's review process includes unbundling rates to isolate components like generation, transmission, and distribution charges, with recent adoption of the Trending Method for valuing Meralco's regulatory asset base to exclude non-useful or stranded assets, thereby protecting consumers from over-recovery. Rate adjustments, including pass-through of fuel and purchased power costs, require ERC confirmation to prevent undue hikes, though delays in finalizing resets—spanning over a decade for Meralco's prior cycle—have prompted calls for expedited proceedings starting October 17, 2025. The ERC also monitors post-approval performance, imposing penalties for shortfalls in targets or refunds for over-collections, as evidenced by its authority to enforce adjustments in prior provisional approvals.

Controversies and Criticisms

High Power Rate Investigations and Defenses

Meralco has faced multiple investigations into its high electricity rates, primarily driven by consumer complaints and legislative scrutiny over perceived excessive pricing. In 2013, the Energy Regulatory Commission (ERC) approved a rate hike allowing Meralco to recover ₱22.64 billion in underrecovered generation costs from consumers, a decision upheld by the in July 2022 after nearly a decade of litigation, prompting renewed accusations of overcharging despite the regulatory approval. Legislative probes, including inquiries, have examined rate hikes, with calls in 2024 for the ERC to justify an anticipated 32-33 centavos per kWh increase in October due to pass-through costs. In September 2025, protests highlighted alleged overcharging of ₱115 billion between 2012 and 2022, attributing it to malpractices in billing and supply agreements. The ERC has conducted ongoing reviews of Meralco's rate adjustments, denying certain petitions for hikes, such as a 2022 joint request with San Miguel Corporation subsidiaries lacking basis, while affirming others like average rate schemes in June 2024. In cases involving supply deals, the ERC planned to escalate disputes with Meralco and affiliates to the Supreme Court following a 2023 decision on cost pass-throughs. Senatorial calls, including from Sherwin Gatchalian, have urged ERC scrutiny of hikes linked to Wholesale Electricity Spot Market (WESM) fluctuations and independent power producer (IPP) charges, amid broader concerns over collusion in generation costs dating back to 2013 probes. Meralco has defended its rates by emphasizing ERC oversight, stating that all adjustments undergo strict regulatory review and approval, with distribution charges remaining unchanged for 10 years and among the lowest nationally at around 4% of total bills. The company attributes increases primarily to pass-through generation and transmission costs, including rises in WESM prices (e.g., from ₱4.59 to ₱3.04 per kWh in September 2025, yet still contributing to net hikes), IPP and power supply agreement (PSA) expenses due to peso depreciation, and fuel import dependencies. Meralco refuted specific overcharging claims, such as those by Rep. Dan Fernandez, arguing they ignore regulatory compliance and comparative efficiencies against electric cooperatives, where lower rates reflect smaller scales and different policy frameworks rather than superior management. In August 2025, it highlighted higher generation charges from IPPs and WESM as key drivers for a rate uptick, rejecting narratives of profiteering by noting system losses and non-technical factors like pilferage add only marginal costs.

Syndicated Estafa and Bribery Allegations

In May 2008, the National Association of Electricity Consumers for Reform (Nasecore) filed a for syndicated estafa with the Department of Justice against 17 Meralco executives, including chairman Manuel Lopez, alleging the conversion of approximately P889 million in interest accrued on customer meter and bill deposits into company income since 1995. Nasecore claimed this violated consumer rights to interest at rates of 6% for pre-1995 subscribers and 10% for later ones, with Meralco specifically converting 4% of accrued interest from 1995 to 2003 into income in 2006, despite halting the practice in 2004 following Energy Regulatory Commission directives under the for Residential Consumers. The Department of Justice determined on August 22, 2008, due in part to Meralco's failure to submit counter-affidavits, and authorized the filing of charges in court. However, on October 10, 2008, Regional Trial Court Branch 71 Judge Franco Falcon dismissed the case against all accused for lack of , ruling that the executives did not constitute a criminal under Presidential 1689 (requiring five or more persons conspiring for estafa), that the funds were held corporately rather than personally misappropriated, and that any obligation to refund deposits represented a civil debtor-creditor relationship enforceable by the ERC rather than criminal . Amid concurrent disputes, including a May 2008 proxy validation conflict with major shareholder Government Service Insurance System (GSIS), Court of Appeals Justice Gregory Ong's associate, Rodolfo Sabio, publicly alleged in July 2008 that businessman Francis de Borja—an emissary purportedly acting on Meralco's behalf—attempted to bribe him with P10 million to inhibit Ong from the case or transfer it to another division. The Supreme Court, in a September 2008 probe, sanctioned five CA justices (including Sabio with a two-month suspension) for ethical lapses but referred de Borja to the DOJ for investigation into attempted judicial bribery, without directly charging Meralco as an entity. No convictions against Meralco executives resulted from these bribery claims. Meralco has faced multiple rulings mandating compliance with Republic Act No. 7832, the Anti-Electricity and Electric Transmission Lines/Materials Pilferage Act of 1994, which permits disconnection for non-payment or pilferage only after , including prior written notice. In June 2023, the denied Meralco's petition for review in Manila Electric Company v. Yu (G.R. No. 255038), affirming that disconnection without at least 48 hours' written notice violates Section 4(a) of RA 7832, entitling affected customers to reconnection and damages. The Court emphasized that such notice must specify the amount due and disconnection grounds, rejecting Meralco's argument for immediate action in pilferage cases. Similar violations occurred in Manila Electric Company v. Spouses Sulpicio and Patricia (G.R. No. 223601), where the upheld a lower court's award of and exemplary damages against Meralco for disconnecting service without to a business establishment, citing failure to observe under RA 7832. In that case, decided in 2023, the Court noted Meralco's pattern of non-compliance, ordering permanent reconnection and P500,000 in total . Another instance involved Meralco v. Castillo, where hasty disconnection for alleged arrears led to Supreme Court affirmation of , underscoring that even suspected illegal use requires procedural safeguards. Disputes over differential billing and meter tampering assessments have also triggered disconnection threats, prompting formal complaints to the Energy Regulatory Commission (ERC) or courts, as customers contest assessments without evidence of tampering. In Meralco v. Spouses Ramos (G.R. No. 195145), the Regional Trial Court ordered reconnection and P2 million in damages after finding unlawful disconnection, a ruling upheld on appeal for lacking notice. These cases highlight judicial scrutiny of Meralco's enforcement practices, with courts prioritizing consumer protections over utility recovery interests absent strict procedural adherence. Regarding allocations, limited documented disputes involve Meralco's handling of distribution during peak demands or in multi-unit settings, but no major Supreme Court-level cases directly address allocation-specific disconnections as of 2025. Instead, allocation challenges often intersect with rate disputes before the ERC, where Meralco petitions for recovery of costs tied to supply contracts, without explicit linkage to disconnection litigation. Customers alleging unfair allocation in subdivided services have pursued ERC , but outcomes emphasize notice requirements over reallocation mandates.

Achievements and Innovations

Infrastructure Modernization and Reliability Improvements

Meralco has undertaken significant s to modernize its distribution network, including a planned P25 billion allocation for 2025, with approximately 60 percent directed toward network enhancements such as smart grids and underground cabling for improved resiliency. The company aims to install an additional 1,500 circuit kilometers of underground power cables by 2030 to mitigate risks from weather-related disruptions and urban development pressures in its franchise area. These efforts form part of a broader five-year, $3.7 billion program focused on upgrading substations, transmission lines, and digital to handle rising demand and integrate sources. In the second quarter of 2025, Meralco completed nine major projects, adding 450 megavolt-amperes (MVA) of capacity and enhancing reliability across , , Laguna, and provinces. Key initiatives included the energization of sub-transmission lines, such as the Dila-Real 115 kV line upgrades in Laguna, and expansions like the 115 kV – 34.5 kV gas-insulated switchgear (GIS) substations to support loads. Additional investments, totaling around P1.9 billion to P2 billion, targeted switching stations and transformer capacity increases, such as boosting the Power from 100 MVA to 300 MVA in Southern Luzon. These modernization efforts have yielded measurable reliability gains, as evidenced by improvements in key performance indicators. In 2024, Meralco achieved a 13 percent reduction in both the System Average Interruption Frequency Index (SAIFI) and System Average Interruption Duration Index (SAIDI) compared to prior years. For the first half of 2025, SAIFI declined by 13 percent and SAIDI by 12.9 percent, with SAIDI specifically dropping to 20.943 minutes per customer from 22.336 minutes. Partnerships, such as with Itron for smart metering across 73,000 endpoints in Metro Manila, further support grid optimization and real-time monitoring to reduce outages.

Sustainability and Efficiency Initiatives

Meralco has integrated into its operations through a clean strategy, including a target to secure 1,500 MW of capacity by 2025 via its MGreen. By August 2025, MGreen exceeded its interim goal of 778 MW in solar development, with the of 152.7 MWac across three Luzon-based solar projects in the first quarter of the year. Operational assets include the 55-MW BulacanSol solar farm, contributing to distributed clean power generation. Larger-scale efforts encompass the MTerra Solar , a multi-gigawatt initiative aimed at powering up to 2 million homes by 2027, supported by a US$600 million investment closed in March 2025. The company advocates for nuclear energy as a low-emission baseload option, advancing feasibility studies and policy support to incorporate it into the Philippine grid by the late 2020s. Long-term goals include achieving coal-free operations by 2050, alongside expansions and hybridized supply systems for remote areas to enhance resilience and reduce reliance. Complementary measures involve fleet —targeting full transition by end-2022 for initial phases—and adoption of biodegradable transformers to minimize environmental impact from equipment failures. On efficiency, Meralco provides energy audits, guidance, and installations—such as LED retrofits—that have enabled clients to cut consumption by 20-30%. Consultations focus on optimizing load and power factors, alongside integration of renewables to lower operational costs. Distribution loss reductions, achieved via anti-illegal connection drives and upgrades, have decreased system loss charges by up to 21% in recent billing cycles, directly lowering customer rates. of distribution transformers emphasizes total owning cost metrics, prioritizing low-loss models to curb technical inefficiencies. Pilot deployments of 10,000 smart meters in , completed by September 2025, enable real-time monitoring to further optimize grid performance and reduce non-technical losses. These efforts align with the Energy Efficiency and Conservation Act, mandating plans for supply stability and waste minimization.
