How much long-duration energy storage (LDES) does the UK system need, is the government’s cap-and-floor the right way to procure it, and what does the long-term picture look like?

Just over 70% of the successful projects in the first window of the UK’s long-duration energy storage (LDES) scheme are using lithium-ion BESS technology.

Projects supported by the UK government’s long-duration energy storage (LDES) cap-and-floor could significantly dampen price spreads but also affect non-LDES flexibility assets.
