ElectroRoute Secures 15-Year Deal to Market 462-MWp UK Solar Portfolio

• BSR signs a 15-year PPA with ElectroRoute for 462 MWp of UK solar, securing bankable revenues and expanding ElectroRoute’s managed portfolio to 3 GW.

British Solar Renewables (BSR) has inked a landmark 15-year route-to-market power purchase agreement (PPA) with Dublin-headquartered energy trader ElectroRoute, covering 462 MWp of solar capacity spread across nine sites in England and Wales.

Under the arrangement, ElectroRoute will take on 24/7 trading and balancing responsibilities, optimising generation schedules and capturing wholesale price spikes to maximise revenues from an expected 482 GWh of annual output—enough clean electricity to supply roughly 130,000 UK households.

For BSR, the contract de-risks a significant portion of its operational fleet at a time of volatile power prices and tightening grid constraints. Securing a bankable offtake partner unlocks access to long-tenor project finance and paves the way for further build-out of the developer’s 3-GW pipeline. “Long-term certainty around cash flows is critical to crowding private capital into new renewable assets,” a BSR spokesperson noted, adding that the deal “underlines investor confidence in the UK’s net-zero trajectory even as policy headwinds persist.”

ElectroRoute, wholly owned by Mitsubishi Corporation, now manages more than 3 GW of wind and solar assets across the UK, Ireland and Japan. The agreement follows a 61-MW PPA signed with Innova Renewables in June and signals the trader’s intent to scale its merchant services offering as subsidy-free renewables become the norm.

The partnership also illustrates how sophisticated power-trading strategies—leveraging real-time market data, weather forecasting, and AI-driven dispatch optimisation—are increasingly central to squeezing value from intermittent generation. ElectroRoute’s trading desk will dynamically shift export profiles, participate in balancing markets, and hedge forward production to stabilise cash flows for BSR and its lenders.

Industry analysts view the transaction as another vote of confidence in UK solar amid ongoing grid and planning bottlenecks. “Bankable PPAs like this are vital for turning shovel-ready projects into steel-in-the-ground,” said Tom Haddon, director at consultancy Aurora Energy Research. “They also help relieve price cannibalisation risks by actively managing when and how power is sold.”

With utility-scale solar costs continuing to fall and storage economics improving, market observers expect similar multi-GW route-to-market deals to accelerate as developers race to meet Britain’s 70-GW solar ambition for 2035.
