Great Britain GB electricity system operator – demand-side response (DSR) is more reliable than nuclear power

The Energyst 18th July 2019 The GB electricity system operator has suggested demand-side response (DSR) is more reliable than nuclear power in its latest Capacity Market auction
guidelines. National Grid ESO has given DSR a de-rating factor of 86 per
cent, while nuclear is de-rated to 81 per cent.

DSR is also deemed to be
marginally more reliable than biomass, coal and most interconnectors, per
the guidelines. Industry participants suggested the move reflected the
expertise of DSR providers in managing their portfolios. “Presumably [the
de-rating factors] reflects recent reliability of the UK nuclear fleet, and
superior performance of aggregators in delivering contracted response,”
wrote Jon Ferris, strategy director at energy blockchain firm Electron.

His comments were welcomed by the Association for Decentralised Energy.https://theenergyst.com/national-grid-dsr-more-reliable-than-nuclear/
