National Grid procured 90 MW of dynamic containment, the new premium frequency response product on Thursday in the first ever auction of this type. The product is faster acting than Firm Frequency Response, with DC output delivered in 0.5 seconds compared with 2 seconds.
– 165 MW of assets bid by operators into the day ahead auction
– 26 MW withdrawn
– 49 MW rejected by National Grid on price grounds (with £24/MW/hr deemed too steep a price to pay).
National Grid aim to procure 500 MW Low Frequency response from the auction to begin with. They have plans to increase that to 1000 MW Low and High in the future. This is something Limejump is actively exploring as it represents an exciting new service for battery owners..
