Slow Reserve is live

Slow Reserve is now live, replacing the STOR service from 1 April 2026. Slow Reserve is a new service designed to help balance the grid by instructing assets to increase or decrease demand/generation within 15 minutes.

Slow Reserve (SR) is aimed at reacting to post-fault disturbances to restore energy imbalances to +/- 0.2Hz within 15 minutes of a loss event (generation or demand). The service is open to any technology with the ability to provide a net change in demand/generation of at least 1MW.

How GridBeyond can help I&C businesses participate

For industrial and commercial energy users, Slow Reserve represents a tangible new revenue stream and GridBeyond is well positioned to help businesses unlock it. GridBeyond enables industrial and commercial energy users across a range of sectors to actively participate in energy services and grid balancing programmes.

With Slow Reserve’s 15-minute response window, many I&C assets that couldn’t participate in faster frequency response services may now be eligible, making this one of the most accessible balancing markets for demand-side participants.

GridBeyond’s AI-driven platform leverages digital twins and advanced forecasting to unlock hidden flexibility while ensuring operational constraints are never compromised. This is particularly relevant for Slow Reserve, where businesses need confidence that any dispatch will be managed precisely and safely within their site’s operational parameters.

Beyond Slow Reserve, GridBeyond’s platform stacks market opportunities, forecasting grid conditions, short-term wholesale market prices, and balancing actions to ensure your energy flexibility is placed into the most lucrative market at the right time. This means participation in Slow Reserve can be layered alongside other revenue streams such as Dynamic Containment, the Capacity Market, or wholesale trading, maximising the overall return from your site’s flexibility.
