[SMM Flash News] UK's Ofgem Selects 16 LDES Projects Totaling 7.6 GW Under Cap and Floor Regime
UK energy regulator Ofgem has provisionally selected 16 long-duration electricity storage (LDES) projects, representing 7,645 MW of capacity, under the first application window of the LDES cap and floor regime. Ofgem has published its "minded-to" decisions to support these projects and is currently seeking feedback via a public consultation that will close on August 7, 2026. The final cap and floor awards are expected to be announced in the autumn. The selected projects cover a variety of technologies, including pumped hydro, vanadium redox flow, compressed air, and lithium-ion batteries. The regulator noted that this capacity aligns with the upper end of the National Energy System Operator’s (NESO) recommended range. Further application windows are anticipated, subject to additional consultations this year and a decision on a second window by 2027.
