| E.ON said the facility, which is next to an existing power plant and has the equivalent capacity of half a million phone batteries, marked a milestone in its efforts to develop storage for power from wind farms, nuclear reactors and gas power stations. | E.ON said the facility, which is next to an existing power plant and has the equivalent capacity of half a million phone batteries, marked a milestone in its efforts to develop storage for power from wind farms, nuclear reactors and gas power stations. |
| The plant, which will be the first of many similar facilities and is housed in four shipping containers, is the type of project hailed by the business secretary, Greg Clark, as crucial to transforming the UK’s energy system and making it greener. | The plant, which will be the first of many similar facilities and is housed in four shipping containers, is the type of project hailed by the business secretary, Greg Clark, as crucial to transforming the UK’s energy system and making it greener. |
| At 10MW, the Blackburn Meadows battery is the biggest in Britain so far, but will soon be eclipsed by much larger plants. | At 10MW, the Blackburn Meadows battery is the biggest in Britain so far, but will soon be eclipsed by much larger plants. |
| Centrica, the parent company of British Gas, is building a 49MW facility on the site of a former power station in Barrow-in-Furness, Cumbria, while EDF Energy is working on one of the same size at its West Burton gas power station in Nottinghamshire. | Centrica, the parent company of British Gas, is building a 49MW facility on the site of a former power station in Barrow-in-Furness, Cumbria, while EDF Energy is working on one of the same size at its West Burton gas power station in Nottinghamshire. |

| The utility-scale batteries are being built in response to a request from National Grid, the owner of Britain’s power transmission network, for contracts to help it keep electricity supply and demand in balance, which is posing an increasing challenge for the grid as more intermittent wind and solar comes online. | The utility-scale batteries are being built in response to a request from National Grid, the owner of Britain’s power transmission network, for contracts to help it keep electricity supply and demand in balance, which is posing an increasing challenge for the grid as more intermittent wind and solar comes online. |
| Balancing supply and demand is essential for keeping the frequency of electricity constant at 50Hz across the UK. The ability of batteries to respond to demand in less than a second makes them ideal for the task, with earlier sources of backup power much slower at just under 10 seconds. | |
| E.ON has secured £3.89m of the £65.9m of contracts awarded for the service, though National Grid estimates the batteries will save it £200m over four years. | E.ON has secured £3.89m of the £65.9m of contracts awarded for the service, though National Grid estimates the batteries will save it £200m over four years. |
| Leon Walker, the commercial development manager at National Grid, said: “Using battery storage is a significant development for managing the national grid. It’s an ultra-fast way of keeping electricity supply and demand balanced.” | Leon Walker, the commercial development manager at National Grid, said: “Using battery storage is a significant development for managing the national grid.

| The new generation of batteries will also earn their owners money by helping with the government subsidy scheme for providing backup power during winter, known as the capacity market. The storage plants will also be able to take power off the system when supply is unexpectedly high, such as on a particularly windy or sunny day. | The new generation of batteries will also earn their owners money by helping with the government subsidy scheme for providing backup power during winter, known as the capacity market.
