Tender opportunity from our DNO partner

Scottish and Southern Electricity Networks (SSEN) is introducing constraint managed zones (CMZ) into its every day network operations.

A CMZ is a geographic region served by an existing network where network requirements related to network security of supply are met through the use of flexibility services, such as demand side response, energy storage and stand-by generation.

SSEN is launching a procurement process to identify a supplier and determine a most economically advantageous tender for the provision of CMZ.
