This successful auction outcome, with 140 MW (derated) of the T-1 auction allocation secured, confirms Enel X’s position as a GB market leader in DSR, continuing a track record of consistently high performance on behalf of their customers in these auctions. The company has already secured obligations at the highest available pricing for the following two years (i.e. 1st of October 2025 to the 30th of September 2027), meaning Enel X clients will enjoy the greatest return from the Capacity Market up until September 2027, provided they complete enrolment within the approaching deadline: 

  • 1st March of 2024 for onsite generation customers (e.g. CHP, Battery Energy Storage, etc);
  • 31st May of 2024 for load curtailment customers.


Participation in the GB Capacity Market gives industrial and commercial businesses a significant advantage over non-participants by: 

  • offsetting volatile energy prices and maintaining a competitive cost base;
  • achieving greater energy security and protecting business continuity; 
  • accelerating their Net Zero ambitions and delivering on ESG (Environmental, Social, and Governance) commitments.


The Capacity Market mechanism ensures electrical energy security by helping to balance supply with demand, especially during times of grid stress. Great Britain’s National Grid (NG) ESO (Energy System Operator) views it as crucial for delivering a secure, sustainable, and affordable electricity system.


Businesses that already have energy generation or storage assets, such as CHPs and battery energy storage systems, are ideal candidates. It is also possible to participate by temporarily reducing consumption (i.e. Load Curtailment) of everyday equipment such as lighting, HVAC (Heating, Ventilation, and Air Conditioning) systems and refrigeration units. 


Any business in any sector with the ability to switch on, or turn down, one MW or more of capacity can participate in the Capacity Market and get paid for their flexibility. This could be from a single site or across multiple locations. There is no upper limit if sufficient positions are available. 
Enel X has provided DSR services to Great Britain’s electricity system since 2009 and currently holds the leading position in DSR programmes worldwide, with over 9.5 GW of capacity managed in Europe, the Americas, Asia, and Oceania.
