High levels of embedded generation have posed balancing challenges for some years. This summer, though, the National Grid Electricity System Operator (NGESO) must manage exceptionally low demand on the National Transmission System due to the lockdown brought about by the coronavirus disease 2019 (COVID-19) pandemic. To assist managing this demand, NGESO has developed a new Optional Downward Flexibility Management (ODFM) scheme for commercial scale distributed renewable generators who do not participate in the balancing market. The service went live at 11 p.m. on 8 May 2020, and will remain in place for the summer periods. A letter to the industry published on 1 May 2020, invited participants to sign onto the terms to enable them to offer operational downward flexibility. Rob Broom (associate) and Paul Brennan (consultant) from our Energy & Natural Resources Practice, take a closer look at the ODFM scheme in this client alert.
