Optimising PPAs for Renewable + Storage Integration in the UK Grid

Synopsis

Battery storage is becoming essential to strengthen project economics and enhance reliability, especially amid the UK’s drive for energy security and resilience. Yet integrating storage into PPAs requires new commercial thinking. Contract design must capture fluctuating storage value, degradation, and lifespan, while navigating Ofgem’s evolving rules and National Grid ESO’s flexibility reforms.

• From generation-only to hybrid PPAs: how corporates evaluate renewable + storage propositions and what drives contractability
• Defining commercial structures for co-located storage: duration, dispatch rights, degradation risk, and revenue stacking within PPAs
• What unlocks demand: practical examples of buyer-led requirements that make storage-integrated PPAs bankable and scalable
