AES Indiana, formerly known as Indianapolis Power & Light Company (also known as IPL or IPALCO), is an American utility company providing electric service to the city of Indianapolis. It is a subsidiary and largest utility of AES Corporation, which acquired it in 2001. AES Indiana provides electric service to more than 500,000 customers in a 528-square-mile (1,370 km2) service territory.

Key Information

On February 24, 2021, IPL was rebranded as AES Indiana.[1]

History

[edit]
A 1920 newspaper advertisement for Merchant's Heat and Light Company.

AES Indiana was formed as the Indianapolis Power and Light Company in October 1926 by the merger of the Indianapolis Light and Heat Company and the Merchant's Heat and Light Company. Those two companies had started providing electrical service in the 1880s. At the time of the merger, the company had 105,000 customers.[2] In 1937, IPL began a rural electrification program, running power lines to many areas outside Marion County.[3]

The company moved into its present-day headquarters building on Monument Circle in downtown Indianapolis in 1935; the building, now known as the Electric Building, had been constructed in 1924 for the Continental Bank.[2] The building was remodeled in 1968 to a design by Lennox, Matthews, Simmons & Ford, with the lighting design by Norman F. Schnitker.

In the late 1980s, the Internal Revenue Service audited IPL and assessed a tax deficiency on deposits that IPL required of customers with poor credit histories. The ensuing court case, Commissioner v. Indianapolis Power & Light Co., resulted in a United States Supreme Court ruling in 1990 that such customer deposits to a public utility were not taxable income.

In 2008, IPL integrated the world's first grid scale lithium ion battery energy storage system, with four megawatts of battery storage validated for frequency regulation.[4]

IPL was acquired by the AES Corporation in 2001. On February 24, 2021, IPL's name was changed to AES Indiana. At that time the company had 500,000 customers.[1]

On April 25, 2021, the company's Eagle Valley Generating Station's Toshiba steam turbine was unable to resynchronize with the grid when it was restarted after a maintenance outage. The problem was caused by a disconnected wire that "provided false indication to the control system". Repairs to the resulting damage to the rotor and other components was hampered by incorrect wiring diagrams in the system manuals and could not be completed until November 2021. The company's Petersburg Generating Station also was undergoing repairs during part of the time, causing AES to purchase $1 million of electricity to cover the shortage.[5]

Generating plants

[edit]

The company owns and operates three coal-fired generating plants, a combustion turbine, and a wind farm, giving the company a total nameplate generating capacity of 3,513 MW of power.

History

Founding and Early Development

Indianapolis Power & Light Company (IPL), the predecessor to AES Indiana, was formed on October 27, 1926, through the merger of the Indianapolis Light and Heat Company and the Merchants Heat and Light Company, two prominent utilities that had been competing in the city's electric and heating markets. This consolidation created a unified entity to serve 's growing urban population, beginning operations in January 1927 with approximately 105,000 customers primarily in the city's core areas. The merger addressed the fragmented utility landscape, where intense competition among at least ten electric providers established between 1892 and 1912 had led to inefficiencies and service overlaps, reducing the field to just two major players by 1927. From its inception, IPL concentrated on urban electrification, expanding reliable power to homes, businesses, and landmarks in to support the city's industrial and commercial growth. A notable example was the supply of electricity by its predecessor, the Indianapolis Light and Heat Company, to the under-construction Continental Bank building on Monument Circle in 1924, highlighting early efforts to integrate power into the urban infrastructure. In the late and early , IPL faced challenges such as modernizing inherited distribution networks amid economic pressures from the , which necessitated innovations like unified grid improvements and the integration of high-pressure steam systems with electric distribution to enhance efficiency for industrial users. These advancements in local power distribution focused on reducing outages and expanding capacity within the , laying the groundwork for more reliable service before venturing into rural areas in the following decades. In 1935, IPL relocated its headquarters to the former Continental Bank building at 1 Monument Circle, which it acquired through a sale and renamed the Electric Building, symbolizing its central role in the city's energy landscape. This move coincided with ongoing efforts to streamline urban operations, including the adoption of emissions-reduction technologies at power facilities to address environmental concerns in densely populated areas.

Mid-20th Century Expansion

Following its establishment as a major urban provider in Indianapolis, Indianapolis Power & Light Company (IPL) pursued significant infrastructure development in the mid-20th century to accommodate rising electricity demands. In the late and , the company constructed additional generating facilities, primarily coal-fired , to bolster capacity and support operational growth. This buildup was essential as post-World War II population increases, suburban development, and the proliferation of electric appliances drove a surge in consumption across central . IPL's expansion extended service beyond the core city limits, incorporating surrounding areas within a growing 528-square-mile territory that included portions of Marion County and adjacent regions. By the late , these efforts had grown the customer base to approximately 380,000, marking key milestones in residential and commercial service from earlier figures of around 105,000 in the . To manage this scale-up, IPL expanded its workforce, enabling reliable delivery to an increasingly diverse user base amid Indiana's industrial expansion. The company's mid-century initiatives had notable economic ramifications for , particularly during periods of rapid industrialization. Reliable power infrastructure facilitated wartime production in local sectors during the and sustained post-war economic vitality by powering new businesses and housing developments. This contributed to the state's broader transition toward a modern, electrified economy, where utilities like IPL played a pivotal role in fostering industrial and urban growth.

Acquisition by AES Corporation and Rebranding

In March 2001, AES Corporation completed its acquisition of IPALCO Enterprises, Inc., the parent company of Indianapolis Power & Light (IPL), in a stock-for-stock transaction valued at approximately $3 billion, integrating IPL into AES's global portfolio of utilities and power generation assets. This move marked AES's expansion into regulated utility operations in the United States, allowing IPL to leverage the parent company's international expertise in energy management while continuing to serve its central Indiana customer base. Following the acquisition, AES implemented operational enhancements at IPL, including diversification of its energy portfolio with a mix of conventional and renewable sources to improve system reliability and efficiency.

Infrastructure and Reliability

AES Indiana's transmission and distribution network forms the backbone of its power delivery system, serving a 528-square-mile territory in central . The transmission infrastructure includes 458 circuit miles of 345 kV lines and 408 circuit miles of 138 kV lines, interconnected with neighboring utilities such as (AEP) and Duke Energy Indiana (DEI) to ensure robust power flow. This high-voltage network connects to 101 distribution substations, which step down voltage for local delivery across 3,619 miles of overhead primary lines and 4,208 miles of underground primary lines. The system supports a summer peak load of approximately 3,100 MW as of 2024, enabling reliable service to residential, commercial, and industrial customers while accommodating load growth through ongoing expansions like the Winding Ridge substation project, which adds 2.7 miles of 138 kV lines. Reliability performance is tracked through standard industry metrics reported to the Regulatory Commission (IURC). In 2023, excluding major events, AES Indiana achieved a (SAIFI) of 0.98 outages per customer and a System Average Interruption Duration Index (SAIDI) of 86.69 minutes per customer, with an average interruption duration () of 88.19 minutes—indicating strong service continuity compared to state averages. Restoration efforts are prioritized during disruptions, as demonstrated by the extended forced outage at the Eagle Valley Combined Cycle Generating Station from April 25, 2021, to March 18, 2022, which necessitated $41.5 million in purchased power and other costs; AES Indiana mitigated broader impacts through rapid procurement and system balancing, ultimately forgoing recovery of $21 million from customers via IURC settlement. These metrics underscore the utility's focus on minimizing downtime, with major event exclusions highlighting consistent operational resilience. To enhance grid reliability, AES Indiana has committed $1.2 billion over seven years to its Initiative, launched in 2018, which deploys advanced metering infrastructure (AMI), distribution automation, and voltage optimization technologies across the network. As of 2025, distribution automation is 92% complete and the conversion of 4 kV lines to 13.2 kV is 75% complete. These investments enable real-time monitoring, automated fault isolation, and faster outage response, reducing restoration times by up to 50% in targeted areas. For instance, the revAMP plan includes converting 4 kV lines to higher voltages and installing smart switches to isolate issues without affecting large customer segments. Such modernization efforts are visualized publicly through the AES Indiana Smart Map, promoting transparency in infrastructure upgrades. A dedicated workforce of over 1,000 employees supports the maintenance and operations of this , with key roles including transmission and distribution (T&D) operators who monitor control centers 24/7, linemen and technicians who perform routine inspections and repairs on lines and substations, and planning engineers who coordinate upgrades. The Director of T&D Operations oversees these teams, ensuring compliance with (NERC) standards and swift response to emergencies. This skilled personnel base is essential for proactive vegetation management, equipment testing, and emergency restorations, contributing to the system's .

Regulatory Oversight

AES Indiana operates as a regulated under the primary oversight of the Indiana Utility Regulatory Commission (IURC), an administrative agency that regulates public utilities in the state to ensure fair rates, reliable service, and compliance with statutes governing electric operations. The IURC reviews and approves the utility's rates, tariffs, and service rules, conducts hearings on proposed changes, and enforces compliance requirements related to safety, financial reporting, and . This oversight extends to valuations of used in rate base calculations and authorizations for facility modifications or expansions. Key regulatory filings with the IURC include periodic rate cases to adjust base rates for recovering costs associated with generation, distribution, and customer service. For instance, on June 3, 2025, AES Indiana petitioned the IURC for a rate increase to address escalating operational expenses and fund infrastructure upgrades, in which the utility filed a partial settlement agreement in October 2025 proposing a reduction of the adjustment to approximately $10 monthly for a typical residential customer using 1,000 kWh, pending IURC approval. The IURC also grants approvals for major capital investments via certificates of public convenience and necessity (CPCN), such as the 2024 filing for acquiring a 170 MW solar-plus-storage project from Lightsource bp. Additionally, AES Indiana's fuel adjustment clause (FAC) mechanism allows quarterly bill adjustments based on actual fuel and purchased power costs, with filings subject to IURC audits for cost reasonableness and efficiency. At the federal level, AES Indiana is subject to the jurisdiction of the (FERC) for interstate aspects of its operations, including wholesale power sales and transmission services. As a participant in the (MISO) regional transmission organization, the utility must adhere to FERC-approved standards of conduct to prevent undue in transmission access and files reports on open access transmission tariffs. Examples include FERC filings for negotiated rate agreements, such as the 2024 agreement under FA1560 effective July 1, 2024, which facilitates specific transmission services. The 2001 acquisition of Indianapolis Power & Light Company by marked a significant corporate shift, after which the utility aligned its practices with the parent's global energy standards while remaining fully subject to IURC authority for state-specific matters. This integration involved IURC approvals for post-acquisition investments and operational enhancements, such as portfolio diversification into renewables, without altering the core regulatory structure. In February 2021, the company rebranded as AES Indiana to better reflect its position within , a change that required no separate IURC filing but underscored ongoing adaptation under existing oversight.

Generation Portfolio

Fossil Fuel Facilities

AES Indiana's fossil fuel facilities have historically provided the majority of its baseload power generation, with a total owned capacity contributing to the utility's overall 3.9 GW portfolio as of 2024. These assets, primarily coal-fired until recent conversions and retirements, have been transitioning toward to reduce emissions while maintaining reliability for its customer base in central . The Petersburg Generating Station, located in Pike County, Indiana, was originally a 1,700 MW coal-fired facility with four units that served as a cornerstone of AES Indiana's generation mix. Unit 1, with a 230 MW capacity, was retired in May 2021, followed by Unit 2's 415 MW retirement in June 2023, reducing the site's active coal capacity to approximately 1,340 MW from Units 3 and 4. In November 2024, the Indiana Utility Regulatory Commission approved the repowering of these remaining units to , a process that began construction in 2025 and is expected to eliminate coal operations by the end of 2026, preserving the site's role in baseload power with lower emissions. The Harding Street Generating Station in features a combined-cycle plant with a 682 MW capacity, originally developed as -fired units that were converted in to support cleaner baseload generation. This facility, encompassing Units 5, 6, and 7 with a historical nameplate of about 673 MW, now operates efficiently using , contributing significantly to AES Indiana's dispatchable power needs amid growing demand.
