The next four-year-ahead (T-4) Capacity Market auction is expected to clear at a record high price for the third year running after the margin between prequalifying capacity and the procurement target fell to its lowest level since the auctions began in 2014. Although the target has been raised slightly to 43GW, according to analysis by EnAppSys, 45.2GW of de-rated capacity has prequalified for the auction in February next year, leaving a margin of less than 2.2GW – or 5%.
