Introduction: The GB electricity network is setting a fast pace for the transition towards a net-zero carbon energy system.  Effective integration of renewable energy sources into the electricity transmission network in an economic and efficient manner is crucial in achieving the UK net-zero carbon target. The aim of this project is to investigate efficient network reinforcement solutions to upgrade the transmission network transfer capability without the need for constructing new lines.  The project will examine the feasibility of using transformative six-phase technology and/or voltage upgrades to increase the power transfer capability of the existing transmission line in the GB network.

Objectives: The objective of the project is to investigate the feasibility of using either innovative six-phase technology or voltage upgrading of existing three-phase overhead lines to increase the power transfer capacity of the transmission corridors for renewable integration.
