The Greater Manchaster Pilsworth Liquid Air Energy Storage Pre-Commercial Demonstrator is a 5,000kW energy storage project located in Bury, UK.

The electro-mechanical energy storage project uses compressed air storage as its storage technology. The project was announced in 2014 and was commissioned in 2018.


The Greater Manchaster Pilsworth Liquid Air Energy Storage Pre-Commercial Demonstrator was developed by Highview Power Storage . The project is owned by Viridor Waste Management (100%).

The key applications of the project are electric supply reserve capacity – non-spinning, frequency regulation, transmission congestion relief, transmission support and voltage support.

Contractors involved

Highview Power Storage and Viridor Waste Management have delivered the energy storage project.

Additional information

The Energy Storage System is funded by a $11,600,000.00 investment from British Government Department of Energy and Climate Change (DECC ). This is the first pre-commercial scale LAES plant of its kind and the largest new energy storage technology project in the UK being built to satisfy the requirement for long duration storage. The project will operate for at least one year and will demonstrate LAES providing a number of grid balancing services in the UK, including Short Term Operating Reserve (STOR), Secondary frequency response testing, Triad Avoidance (supporting the grid during the winter peaks) and also testing for the US regulation market.
