Probabilistic Transmission Planning Procedures Within the CEGB

Abstract

This paper begins by outlining the statutory framework that influences the planning of capital investments within the British electricity supply industry. It discusses the interpretation of this framework to produce guidance to assist the planners of the supply industry. The existing procedure for planning the transmission connections to generating stations is examined and the new probabilistic procedure being developed within the Central Electricity Generating Board (CEGB), which will consider both security and economics, is explained.
