EPEX SPOT and National Grid ESO successfully launch frequency response auction trial in Great Britain

London / Paris, 04 December 2019. The European Power Exchange EPEX SPOT and National Grid Electricity System Operator (ESO) have successfully launched the Frequency Response Auction Trial in Great Britain (GB). The first auction took place on 29 November. In total, 10,284 MW were traded during this first auction. Reference prices for the different products traded are available here.

Following the joint announcement of National Grid ESO and EPEX SPOT in 2018, the partners have developed a platform which hosts these auctions. The trial is designed to demonstrate that closer-to-real-time procurement can enable renewable generation as well as industrial and commercial sites to provide frequency response along with traditional providers. The two-year project is supported by a grant from Ofgem’s Network Innovation Allowance.

The weekly, pay-as-clear auctions take place every Friday. Orderbooks close at 9:30 GMT and results are published on the National Grid ESO’s website at 14:00 GMT, for service delivery starting the same day.

Colm Murphy, Head of Electricity Market Change Delivery for National Grid ESO, said:

“The frequency response auction trial supports a core objective of the Electricity System Operator to remove barriers to entry and promote competition. Participation in the auction by new providers supports us in achieving carbon-free operation by 2025 and the net-zero transition. We expect the auction to increase liquidity in the frequency response market, reduce our overall balancing costs, and deliver value for the end-consumer.”

Ralph Danielski, Chief Executive Officer of EPEX SPOT, comments:

“We are delighted to deliver this new market place that offers important value for flexibility providers in GB. The project represents also a major milestone for our company, as on the back of our expertise in developing and operating short-term energy markets, we now have officially entered the field of balancing services. The new near-term contracts enable access to new players, diversify the segment and ultimately facilitate the energy transition.”

Frequency response is an essential balancing service to mitigate deviations in system frequency caused by unexpected changes in generation or demand. This auction trials a new route to market for National Grid ESO to procure frequency response from industry providers.
