Hydro Tasmania

Hydro Tasmania, formerly the Hydro-Electric Commission (HEC), is a Tasmanian Government business enterprise which is the main electricity generator in Tasmania, Australia. Originally oriented towards hydro-electricity, owing to Tasmania's dramatic topography and relatively high rainfall in the central and western parts of the state, today Hydro Tasmania operates 30 hydro-electric and one gas power station, and is a joint owner in three wind farms.

In 1914, the Government of Tasmania set up the Hydro-Electric Department (renamed the Hydro-Electric Commission in 1929) to complete the first hydro-electric power station, the Waddamana Hydro-Electric Power Station. Prior to that two private hydro-electric stations had been opened the Launceston City Council's Duck Reach Power Station, opened 1895 on the South Esk River (it was one of the first hydro-electric power stations in the southern hemisphere. Reefton Power Station in New Zealand is the first municipal hydro-station, beginning operations in 1888) and the Mount Lyell Mining & Railway Company's Lake Margaret Power Station, opened in 1914. These power stations were taken over by the HEC and Duck Reach was closed in 1955. Lake Margaret was closed in 2006, but after a multimillion-dollar refit was recommissioned in 2009.

Following World War II, in the 1940s and early 1950s, many migrants came to Tasmania to work for the HEC with construction of dams and substations. This was similar to the Snowy Mountains Scheme in New South Wales and similar effects in bringing in a significant number of people into the local community enriching the social fabric and culture of each state. Most constructions in this era were concentrated in the centre of the island.

As the choice of rivers and catchments in the central highlands were exhausted, the planners and engineers began serious surveying of the rivers of the west and south west regions of the state. The long-term vision of those within the HEC and the politicians in support of the process, was for continued utilisation of all of the state's water resources.

As a consequence of such a vision, the politicians and HEC bureaucrats were able to create the upper Gordon river power development schemes despite worldwide dismay at the loss of the original Lake Pedder. The hydro-industrialisation of Tasmania was seen as paramount above all, and the complaints from outsiders were treated with disdain.

Following the flooding of Lake Pedder by the HEC for the upper Gordon Power Development and the subsequent backlash against the HEC incursions into the south west wilderness of Tasmania, environmental groups of the 1970s and 80s alerted the rest of Australia to the continued power that the HEC had over the Tasmanian environment and politics.

Numbers of Tasmanian politicians either rose or fell on their alignment with the support of the HEC and its power development schemes in the south west and West Coast of Tasmania.

When the HEC proposed a dam on the Gordon River, sited below the Franklin River, there was widespread and vigorous opposition. During the Franklin River 'No Dams' campaign it was common for members of families to be in conflict with one another by being aligned with the HEC proposals or the Conservationists.
