Transmission Investment Incentives

In June 2008, we concluded the Transmission Access Review (TAR) in conjunction with the Department for Energy and Climate Change. The following year, in July 2009, the three transmission companies completed a study for the Electricity Networks Strategy Group. This study identified key transmission investment projects that may be required to accommodate future generation and demand patterns in line with meeting the Government's 2020 renewable energy and low carbon targets. The total value of these projects amounted to around £5bn.

Following provision of an initial tranche of money for the projects in most urgent need of funding, we implemented the Transmission Investment Incentives (TII) framework in April 2010. This was designed to provide interim funding for critical investment undertaken prior to the next price control period. This was in line with our Final Proposals document of January 2010. Details of those Final Proposals and other works carried out up to April 2010 are contained in the TAR section of this website. 

The TII workstream handles the ongoing monitoring and allowance setting from April 2010 onwards for projects funded under the TII framework.
