When is a capacity market , not a capacity market but a state aid system

The UK is the first country in the EU to have started a “capacity market”. Under this scheme, the UK government offers payments to electricity suppliers for making “backup capacity” available. The first auction, held in December for capacity in 2018/2019, has resulted in contracts for £931 million for UK power generators. According to Mike Parr, Director of energy consultancy PWR, most of this money is wasted. He says the scheme is overgenerous because it covers the entire 49 GW of capacity in the UK rather than just the 6 GW peak capacity that needs to be covered. It also fails to encourage new-build generation and demand response.
