Britain's biggest community solar farm forced to shut over grid overload fears
9 days ago
- Britain's largest community solar project in north Devon was forced to shut down during its first summer to prevent overloading the local grid with renewable energy.
- The shutdown, ordered by the National Energy System Operator (Neso) due to concerns of thermal overload from rooftop solar, will cost the cooperative's nearly 10,000 members about £2m in lost revenue.
- The shutdown was unexpected and enforced with no warning, occurring just before a heatwave, and will substantially impact the scheme's finances and near-term member payments.
- The problem arises from managing voltage surges from rooftop solar during sunny summer days; necessary equipment upgrades, delayed since 2023, are now due to be completed in September 2024.
- The project does not expect compensation for the lost revenue; it was funded by £20m from cooperative members and a £22m bank loan.
- Originally launched through Ripple Energy, which aimed to create a blueprint for consumer-owned solar parks, the project faced delays and Ripple's bankruptcy before being revived under a volunteer board.
- National Grid confirmed curtailing generation to keep the system secure after Neso's directive and is working with Neso on solutions for temporary constraints.
