Battery storage

Supporting the transition to a low-carbon future

Why storage

Utility-scale energy storage supports our transition to a low carbon future. It enables national electricity grids to accommodate increased penetration of generation from intermittent sources such as renewables, as well as enabling improved efficiency from fossil-fuel generation, such as natural gas.

How does it work?

Battery storage facilities are ideally suited to provide ancillary services to national electricity grid networks. These services help the network operators maintain the correct frequency of alternating current on the grid, along with providing complimentary balancing and reserve services. In certain countries, battery storage systems can enhance security of energy supply through capacity market mechanisms.

Why batteries?

Lithium-Ion technology is the most cost effective and commercially mature of the energy storage systems available.  By connecting a standalone utility-scale project directly to the distribution or transmission grid, we are able to deliver these services at reduced cost and achieve fast response times.

Our Projects

We are currently developing battery storage sites in the UK, Ireland and Italy. Through providing a low carbon alternative to gas and diesel generators, these projects have received support from local campaigners  including Residents Against Dirty Energy, Bristol. In 2017, three of our UK projects began operating:

  • Nevendon Energy Storage Facility, a 10MW site in Basildon, Essex.
  • Lockleaze Energy Storage Facility, 15MW in North Bristol.
  • Wolverhampton Energy Storage Facility, a 5MW site in the centre of the city.

Our 15MW Lockleaze battery storage project was the largest in the UK when it was energised in June 2017. Since then we have secured planning permission for 420MW of projects, which will become operational within the next three years. These include:

  • Lisdrumdoagh Energy Storage Facility, a 75MW site in Monaghan, Ireland.
  • Cloonascragh Energy Storage Facility, a 70MW site in Galway, Ireland.
  • Burwell Energy Storage Facility, a 50MW in Cambridgeshire, UK.
  • Rayleigh Energy Storage Facility, a 10.8MW site in Essex, UK.
  • Ipsley Energy Storage Facility, a 4MW site in Worcestershire, UK

Beyond these projects we have a further 650MW in development and in our pipeline, which will offer a significant contribution towards supporting the further uptake of renewable energy into these countries respective grid networks.
