National Grid is to trial same day frequency response procurement from June 2019.
The two year trial is “for a small volume of frequency response” but will enable less predictable technologies, such as wind, to participate, and give those with demand-side response a clearer picture of what may be required of them and when – as the first delivery window will be 23:00 hours the same day.
National Grid said the auction will be held every Friday morning with results published by early afternoon.
It will procure high frequency dynamic response, low frequency dynamic response, high frequency static response, and low frequency static response.
National Grid will publish its requirements for the following week ahead of the auctions. It also stated that the auction will aim to drive down prices and bids will be accepted in price order regardless of size.
The Electricity System Operator will run a webinar on the trial later this month.

Real-time procurement of frequency response will help to increase participation of clean, low-cost flexibility from distributed energy resources and is a vital step towards creating a level playing field for these services to compete with large generation – who currently hold sole access to real-time balancing markets. We look forward to working with National Grid to help bring these measures into successful commercial operation as early as possible.
