Competitive Tender Process

We are responsible for managing the competitive tender process through which offshore transmission licences are granted.

Granting licences to operate new offshore transmission assets via a competitive tender process means that generators are partnered with the most efficient and competitive players in the market. This should result in lower costs and higher standards of service for generators and, ultimately, consumers.

Offshore Transmission Electronic Tendering Portal
