Transmission Access Review (TAR) 

 

Following publication of the Energy White Paper 2007, Ofgem and the Department for Energy & Climate Change (DECC) convened a joint review of the current framework for access to the GB transmission system with the chief aim being to better support the delivery of 20 percent of electricity supplied by renewable generation by 2020. The following workstreams were formed as a result of this review:

 

  • Interim Connect and Manage: In the short term, where appropriate, Generators may be offered connection dates based on when the local transmission works required to connect them can be completed, i.e. in advance of wider system reinforcement.  The objective of interim connect and manage is accelerating the connection of generation to the grid.  To facilitate this earlier connection, under the current arrangements the transmission licensees may seek derogation from Ofgem against the obligation to comply  the minimum criteria in the National Electricity Transmission System Security and Quality of Supply Standard (NETS SQSS).

 

  • 2020 Measures: In the medium term an assessment of transmission investment requirements up to 2020 was undertaken (see work on Long Term Electricity Network Scenarios ). Details of works carried out after April 2010 on projects initiated as a result of this review are contained within the Transmission investment incentives section of this site.

 

  • Enduring Access Arrangements: The activities being undertaken by the industry, DECC and Ofgem to define the long term access regime that will contribute towards the government’s 2020 target whilst remaining aligned to Ofgem’s principal objectives.

 

This folder also contains details of the work undertaken by the Access Reform Development Group (ARODG) in 2006.
