BW ESS Puts Europe’s Largest BESS Into Commercial Operation In The UK

The title of this post, is the same as that of this article on Energy Storage News.

This is the sub-heading.

BW ESS has put its 350MW/1,240MWh Hams Hall BESS project in the UK into operation, the largest in Europe.

Note.

  1. Hams Hall is in Birmingham
  2. That is roughly a three-and-a-half hour battery.
  3. Hams Hall’s capacity will increase to 400MW/1,424MWh once a second phase is complete.
  4. Google AI said the first phase was commissioned in late October 2026.

The Hams Hall BESS is certainly not on the small side.

In Manchester and Scotland Highview Power are building two liquid-air batteries.

  • The Carrington battery in Manchester will be a 50 MW/300 MWh battery.
  • The Hunterston battery in Scotland will be a 300 MW/3.2 GWh battery.

I can see a lot of healthy competition developing between the two technologies.

The two technologies can both build batteries around the same size.

But liquid-air technology appears to offer a longer duration.
