ESB has acquired a 7MWh battery storage site from renewables developer Anesco for an undisclosed sum – the Irish utility’s first grid-connected energy storage project in GB.

Mill Farm near Grantham, Lincolnshire, comprises six battery storage containers. The project was funded and developed by Anesco. The site went live in April 2018 and benefits from multiple revenue streams.

Jim Dollard, executive director of ESB Generation & Wholesale Markets, commented: “The site will enable us to develop the technical, commercial and regulatory expertise in battery storage and flexible technologies. This will help to make electricity systems more stable and reliable, while allowing for enhanced performance and flexibility of our existing and future plant.”

The batteries at Mill Farm will be monitored by Anesco’s specialist O&M service AnescoMeter.ge.
