Ireland and Northern Ireland could save £17 million on their shared electricity network by using batteries to stabilise the grid.

Researchers from the Queen’s University Belfast (QUB) and power developer AES Corporation say the storage technology can reduce grid inertia, which is how long it takes to get the electricity network running at full speed.

The study suggests 360MW of batteries could provide frequency response as fast as 3,000MW of conventional power generation.

The reduction in grid inertia is expected to cut consumer costs and help keep the electricity system secure and stable.
