Several factors such as growing renewable generation in Scotland are set to increase power transfers across the Scottish boundaries, with a corresponding forecast in thermal constraints and ultimately costs to the end consumer.
We are exploring the development of a new Local Constraint Market to access new sources of flexibility to help manage our most constrained boundaries at and above the B6 boundary
The B6 boundary separates the transmission network at the SP Transmission and National Grid Transmission interface, running roughly along the border between Scotland and England.
We’re keen to develop a market that facilitates access to new providers of flexibility and provide competition to the Balancing Mechanism – and so complementing our existing market for the majority of transmission constraint management. We see this local constraint market working alongside existing ESO and DNO approaches and providing visibility, flexibility and coordinated control through appropriate systems and processes.
LCM will play another part in ESO’s role to:
