One month ahead of each tender, further details on service requirements are published on the Flexible Power Map.

How to participate

Pre-qualified providers with assets in suitable locations on the network are invited to tender.

Pre-qualification is easy. Just register on our Dynamic Purchasing System (DPS) and complete the pre-qualification questionnaire for North (SHEPD) or South (SEPD) network areas. Note that providers with assets in both North and South will need to complete questionnaires for both areas.

The DPS is open for registrations at any time, but pre-qualification questionnaires must be submitted at least 5 working days ahead of the tender open date to be considered.
