Local Constraint Market

We are exploring the development of a new Local Constraint Market to access new sources of flexibility to help manage one of our most constrained boundary's.

The anticipated growth in renewable generation in Scotland is increasing power transfer across the Scottish boundaries, which are forecast to increase constraints at the B6 boundary and ultimately costs to the end consumer.

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 have committed as part of the ESO 5-Point plan for managing transmission constraint our intention to deliver a Local Constraint Market to help tackle the rising constraint costs at the B6 boundary.

Taking the learnings from the delivery of the Optional Downward Flexibility Management (ODFM) service we’re keen to develop a market that facilitates access to new providers of flexibility and provide competition to the Balancing Mechanism – our existing market for the majority of transmission constraint management.

We plan to accelerate the delivery of this market using a 3rd party platform to manage the end-to-end process.

Service Design

Having engaged with stakeholders and our operational teams to develop a draft service design for the LCM, we’re now in a position where we’d like to seek industry views and feedback.  We have therefore launch a light-touch consultation to ensure the LCM service meets the requirements of all stakeholders. 

Please take the time to review our draft service design and respond using the proforma provided by 18:00 Friday 8th April 2022.
