The largest provider of community health care within Adelaide is the not-for-profit Royal District Nursing Service (RDNS), which provides out of hospital care and hospital avoidance care. Energy Adelaide's energy requirements were originally met by the Adelaide Electric Supply Company, which was nationalised by the Playford government in 1946, becoming the Electricity Trust of South Australia (ETSA). Despite significant public opposition and the Labor party's anti-privatisation stance which left the Liberal party one vote short of the numbers needed to pass the legislation, ETSA was privatised by the Olsen Government in 1999 by way of a 200-year lease for the distribution network (ETSA Utilities, later renamed SA Power Networks) and the outright purchase of ETSA Power by the Cheung Kong Holdings for $3.5 billion (11 times ETSA's annual earnings) after Labor MP Trevor Crothers resigned from the party and voted with the government. The electricity retail market was opened to competition in 2003 and although competition was expected to result in lower retail costs, prices increased by 23.7% in the market's first year. In 2004, the privatisation was deemed to be a failure with consumers paying 60% more for their power and with the state government estimated to lose $3 billion in power generation net income in the first ten years of privatisation. In 2012, the industry came under scrutiny for allegedly reducing supply by shutting down generators during periods of peak demand to force prices up. Increased media attention also revealed that in 2009 the state government had approved a 46% increase in retail prices to cover expected increases in the costs of generation while generation costs had in fact fallen 35% by 2012. South Australia has the highest retail price for electricity in the country. Privatisation led to competition from a variety of companies who now separately provide for the generation, transmission, distribution and retail sales of gas and electricity. Electricity generation comes from a range of technologies and operators. ElectraNet operates the high-voltage electricity transmission network. SA Power Networks distributes electricity to end users. The largest electricity and gas retailing companies are also the largest generating companies. The largest fossil fuel power stations are the Torrens Island Power Station gas-fired plant operated by AGL Energy and the Pelican Point Power Station operated by Engie. South Australia also has wind and solar power and connections to the national grid. Gas is supplied from the Moomba Gas Processing Plant
