The planning database records 4 roof-mounted solar schemes on commercial buildings in the postcode districts we cover here, including Tesco Store Bishop Auckland and Peterlee Leisure Centre. These are other organisations' projects, listed from the public record. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through Northern Powergrid. Anything above 3.68 kW per phase needs a G99 application, and the export limit offered shapes the design, so the question is asked before the array is sized.
