Ofgem is to consider Scottish Power’s proposal to create demand side response (DSR) technology classes intended to apply new de-rating factors to energy storage used as part of DSR bids into the Capacity Market in 2019.

British vertically-integrated utility Scottish Power has come under scrutiny from the demand side response (DSR) sector after proposing to national regulator Ofgem that de-rating factors applied to large scale battery storage should be extended to those used to provide DSR in the Capacity Market.

Vertically integrated energy company Scottish Power has submitted a proposal to extend recently introduced battery de-rating factors in Britain’s Capacity Market to storage included in demand side response bids in what has been described as a latest attack on the battery market.
