to stop any dam on the Gordon River, and the proposal and early works on the Gordon-below-Franklin Dam ended in 1983 when it was blockaded by the environmentalists and the recently elected Liberal State Government lost a High Court challenge to the Commonwealth's powers. The new Hawke Labor Government in Canberra had opposed the Franklin dam and had moved to stop its construction. The compromise between the State and Federal government and conservationists led the HEC to see the end of an over fifty year long dam making enterprise in the construction of the Henty River and King River power developments. The limits reached The conservationists and the HEC in the 1980s acknowledged that there were a limited range of options for further power development schemes, and it was inevitable that the substantial workforce within the HEC specifically employed in the investigation and development of further dams would eventually become redundant. Since the late 1990s HEC water storages have been progressively drawn down due to power demand exceeding long term supply, the overcoming of which was the original reason the Gordon-below-Franklin dam was proposed. The shortfall has been offset first by drawing down water storage and in latter years through increasing volumes of fossil fuel power generation, at first fuelled by oil and more recently by gas and, via the Basslink cable link to Victoria, coal. From HEC to Hydro Tasmania In the early 1990s, eastern state governments prepared for the National Electricity Market (NEM) and electricity deregulation. In anticipation of Tasmania joining NEM, the Hydro-Electric Commission was broken up on 1 July 1998, creating three separate state-owned companies: Hydro Tasmania, the electricity generator. Transend Networks, the electricity transmitter. Transend has since merged with Aurora's distribution arm to form TasNetworks. Aurora Energy, the electricity distributor and retailer, which sells and distributes electricity to customers. Tasmania joined NEM in May 2005. Starting from the 1990s, Hydro Tasmania has been investing in wind farms, the first one being the Huxley Hill Wind Farm on King Island, which was completed in 1998. This was followed by two wind farms at Woolnorth with a combined capacity of 140MW. Construction of a fourth power station, the Musselroe Wind Farm with a generating capacity of 168 MW was completed in 2013. It was argued in support of the privatization of Hydro Tasmania that it would result in an increase in revenue and an improvement in company
