• Enhanced Optional STOR

  • National Grid has a requirement for provision of a volume of an Enhanced Optional STOR Service from non-BM Providers on a trial basis for this winter. This service creates an opportunity for National Grid to access additional non-BM volume closer to the real time. We would like to invite tenders from industry providers who can meet the necessary technical and commercial criteria to participate in this service.

    The deadline for tender submission is 8th January 2016 12:00pm.

    We will run a webinar on 5th January 2016 13:00 – 15:00 to explain the service in detail and answer any queries you may have. If you would like to participate in the webinar, please register your interest by emailing: commercial.operation@nationalgrid.com

    Your Contacts for this service trail are: Rebecca Yang (rebecca.yang@nationalgrid.com) or Nick Blair (nick.blair@nationalgrid.com)
