A generator is the equipment used by customers to generate their own electricity (e.g. solar panels). Connecting to the electricity distribution network allows customers to sell any excess power generated back to their retailer. This is known as distributed generation (DG).
Anyone who meets the applicable safety, technical, operational and commercial requirements can connect to the MainPower network. We recommend that before you before you submit your application, you make contact with our Network Services Representative team to discuss your needs (0800 30 90 80 or firstname.lastname@example.org).
