This document presents the conclusions from Project Discovery, Ofgem's year-long study of whether the current arrangements in GB are adequate for delivering secure and sustainable electricity and gas supplies over the next 10-15 years.

We have identified a number of concerns with the current arrangements and have
concluded that significant action will be called for given the unprecedented challenges facing the electricity and gas industries. We are keen to work with consumers, industry and government to find the best way forward. Prompt action will reduce the risk to energy supplies and environmental objectives, and can help reduce costs to consumers.

We have put forward for consultation a wide range of possible policy measures, ranging from improvements in pricing and/or obligations on suppliers to deliver specific levels of supply security, through to models that mandate or secure specific investments in new generating capacity and gas infrastructure.
