Tender description

Constraint Managed Zones — Pre-Qualification. Scottish and Southern Electricity Networks (SSEN) build and operate networks to best meet customer needs using the most efficient and flexible techniques possible. This is why we have introduced Constraint Managed Zones (CMZ) into our every day network operations. SSE is seeking proposals for CMZ services for Bramley, Andover and Tatcham. 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 flexible services, such as DSR (Demand Side Response), Energy Storage and Stand-by Generation. CMZ techniques do not seek to increase capacity but will reduce or time-shift demand to avoid capacity constraints. Since capacity constraints only occur at periods of maximum demand, and only if an outage coincides, CMZ techniques need only be available during pre-defined service windows. Should a CMZ technique require a new electrical Point of Connection to the SSEN network, the CMZ supplier should make a separate application following the normal connection application request if successful in the Pre-Qualification Questionnaire. SSE is seeking proposals for CMZ services for Coxmoor Wood.

Since capacity constraints only occur at periods of maximum demand, and only if an outage coincides, CMZ techniques need only be available during pre-defined Service windows. Should a CMZ technique require a new electrical Point of Connection to the SSEN network, the CMZ supplier should make a separate application following the normal connection application request if successful in the Pre-Qualification Questionnaire.
