Capacity Market

The Capacity Market (CM) aims to ensure there is sufficient capacity during times of network stress by making a monthly £/MW payment to participants who make capacity available to National Grid. When the margin between generation and demand gets tight, a Capacity Market notice will be issued by National Grid and, if a stress event (a national shortage of generation resources) looks likely, we will instruct you to respond

Product Information

  • On supply: on supply and MOP and DC import or export, or an existing CM customer

  • Minimum volume requirement: individual customer 2MW

  • Minimum contract size: 2MW (may be made up of a basket using smaller assets from the same customer)

  • Despatch and runtime: 30 minutes notice to run for time of the event

  • Availability: available whenever a system stress event occurs

Benefits

  • Regular payments: monthly payments will be paid regardless of whether a system stress event has actually taken place or not (subject to delivering as per the Capacity Market unit)

  • Fully managed and supported service: we will manage the relationship with National Grid on your behalf and using our in-house expertise we will advise you when your asset needs to respond
