Our frequency response portfolio stands in the front line of electricity system balancing.
Flexitricity’s frequency response systems are compatible with all of National Grid’s commercial frequency services, including:
Frequency response sites respond to failures at large power stations. Most sites drop load in around a second, and resume normal operation in 30 minutes.
This happens around ten times each year – that’s just five hours of annual service delivery. It’s fast power, but only when the grid really needs it.
Frequency response services are subject to strict technical requirements. Our engineers know how to deliver the quality that National Grid needs.
Before joining frequency response, your site needs the following:
Your site's core business activities take priority at all times. We provide:
As large frequency deviations are relatively rare, we charge National Grid for the availability of the frequency response capacity.
We pass live metering, aggregated across all frequency response sites, direct to National Grid. This validates the availability and generates the payments.
