Building flexibility that the grid can rely on

Grid-scale batteries in the UK continue to scale, while long-duration storage moves from the talking stage to selecting and contracting. It’s no longer a theoretical solution to our future problems, but something that could solve our real-world issues today.

Ofgem has already run the first round of its Long Duration Electricity Storage cap-and-floor regime, and the first projects are due to gain approval in Q2 2026. But how exactly do we ensure that those projects, and the other projects that are hoping to come online in the near-future, are delivered successfully?

That’s why in this Briefing, we’ll turn to the near-term challenge of turning a strong project pipeline into financed, connectable assets – while revenues, safety expectations, and network constraints evolve quickly.
