, known for most of its history as The HEC
, is the predominant electricity
generator in the state of Tasmania
. The Hydro is mainly involved with hydro-electricity
, with power stations including 27 hydro-electric, one thermal
and two diesel
power stations. It also has one wind farm
in service, with expansion and two additional wind farms in progress of being approved. In 1914
, the State Government set up the Hydro-Electric Department (changed to the Hydro-Electric Commission
in 1929) to complete the first HEC power station, the Waddamana power stations
. The Mount Lyell Mining and Railway Company
had built the Lake Margaret Power Station
prior to the HEC completing Waddamana.
Hydro Tasmania was formed on the dis-aggregation of the Hydro Electric Commission on July 1, 1998. This resulted in the division of the formerly government owned department into three companies – Hydro Tasmania which generates the power, Transend Networks which transmits it across the state, and Aurora Energy, the retail arm, which sells and distributes it to customers. This was in anticipation of Tasmania joining the National Electricity Market, which occurred in May 2005.
