About this Event

Britain’s energy networks form a critical backbone to the economy and the development needs of all areas of the country. All consumers from householders to businesses, hospitals or transport operators depend on energy supplies delivered by reliable and safe networks of pipes and wires.

Ofgem has set out its proposals for a five-year investment programme of £25bn, with potential for an additional £10bn or more, to transform Britain's energy networks to deliver greener energy for GB, whilst cutting the cost of this investment for consumers.

Following the publication of Ofgem's Draft Deteminations, we invite you to register your interest in attending the Network Price Control (RIIO-2) Open Meetings.

For more information on RIIO-2 Network Price Controls or to read our Draft Determinations please visit Ofgem's website.
