to over-capacity in the South Australian region of the National Electricity Market. Grid generation capacity was reduced in early 2016 when the Northern Power Station closed. Generation at Pelican Point was increased to full capacity at the request of the South Australian government for at least a week in July 2016, due to much of the state's wind generation being offline due to damaging high winds, and the Heywood interconnector being unavailable due to works associated with a planned increase in its capacity. It returned to only operating one unit (half capacity) and the owner claimed that the National Electricity Market rules prohibited the second unit from responding to a request for electricity market responses on 8 February 2017. The result was that the extremely hot weather in Adelaide plus little wind to drive wind turbines led to the market operator requiring "load shedding" for 27 minutes during the evening electricity demand peak. The owner later clarified that it is not allowed to bid into the market if supply cannot be guaranteed, and it did not have a current gas supply contract for the second unit. It was able to respond promptly once directed to do so on 9 February during continuing high temperature weather. Engie advised AEMO on 5 June 2017 that they were currently operating at half capacity (239 MW), but would make full capacity available to the market (479 MW) as of 1 July 2017.
