    Brief

    Ofgem seeks Cost Assessment advisors to support the Offshore Transmission Owners (OFTO) team in executing regulatory duties and managing tender processes for offshore transmission projects. These services are essential for running effective tender rounds under the Tender Regulations 2015. The advisor will provide consultancy support across multiple areas including evaluation of bidder submissions, financial assessment, and cost review of OFTO assets. The role requires careful evaluation of developer-submitted data to ensure transmission assets are transferred economically and efficiently, that stated costs fairly reflect asset value, and that consumers receive value for money. This is a critical function that enables Ofgem to conduct robust tender evaluation processes and successfully appoint OFTOs for upcoming offshore transmission projects.
