The UK is in the middle of a massive overhaul of its queue system for connecting projects to the grid, and BESS is one of the most oversubscribed technologies, leading to a “nervousness” for a lot of projects, law firm Freeths said.

New rules which will reduce grid fees in the Netherlands by providing ‘non-firm agreement’ (NFA) connections as well as time-weighted rates could improve returns and double projected BESS deployments, an analyst has said, though a project owner was less openly optimistic about it.

The UK government’s recently announced national Battery Strategy was intended as a roadmap to establishing a competitive value chain.
