The new transmission arrangements in the UK

The integration of a significant amount of renewable and in particular wind energy in the Great Britain transmission system requires a fundamental review of the operational and market arrangements of the electricity transmission. The main reviews under way focus on transmission access arrangements (TAR), transmission security standards (GB SQSS) and transmission investment incentives. This paper presents the current arrangements for the aforementioned issues and analyses the drivers behind the reviews. Changes in the current arrangements are suggested and it is intended to identify the interactions between the reviews, which would result to an efficient short-term allocation of transmission resources and long-term least cost investment.
