The capacity market auction specifically for turn down demand-side response has cleared between £45 and £50/kW, according to the EMR delivery body. The exact clearing price will be published at 7pm. Updated: Clearing price is £45/kW/yr.
The result is around double that anticipated by some market participants, and much higher than last year’s Transitional Auction, which cleared at £27.50/kW. Smartest Energy, which was vying for around 100MW of contracts, suggested it would clear at around £25/kW.
National Grid aimed to procure around 300MW, but had leeway to procure up to 500MW if the price fell significantly. In the end it procured 312MW for delivery next winter, making the total value of the auction around £14m.
Given that only 373MW of turn down DSR was bidding for contracts, the high outturn is perhaps unsurprising. It does, however, provide an indication of the volume of turn down DSR in the market, which had previously been an unknown quantity. According to Energyst Media’s end user surveys, the vast majority of demand-side response comes from generation technologies.
Today’s auction was the last set aside purely for turn down DSR. The now defunct Energy and Climate Change Committee urged the government to create policy that favours turn down demand side response over decentralised diesel generation in its final report. Such an approach, via a mooted merit order, would be more environmentally friendly. But it would significantly reduce the current DSR market that is able to contribute to security of supply.
Regulator Ofgem has recently issued proposals that would make engine farms less competitive in the capacity market, but other market participants, such as Flexitricity founder Alastair Martin, believe there is a simpler fix for a market that has failed to deliver a single large scale new build combined cycle gas turbine.
