Transmission Access Review

Following publication of the Energy White Paper 2007, we undertook a joint review with the Department for Energy & Climate Change (DECC) of the framework for access to Britain’s electricity transmission system. The aim was to support the delivery of 20 percent of renewably sourced electricity by 2020.

The documents below summarise the background to DECC's decision to implement an enduring transmission access regime based on a "connect and manage" approach. They also contain our proposed approach and timetable for considering requests from the transmission companies for the funding of major reinforcement projects in relation to construction works that were due to commence before the start of the next price control period.

The documents also refer to our work under the Transmission Investment Incentives (TII) framework. This was implemented in April 2010 to provide interim funding for critical investment undertaken prior to the next price control period. The TII workstream handles the ongoing monitoring and allowance setting from April 2010 onwards for projects funded under the TII framework.
