In England, a battery energy storage system claimed to be among the biggest in Europe has been put into operation.
The Pillswood project, located close to Hull and developed by Harmony Energy Limited, can store up to 196 MWh of power in a single cycle thanks to a Tesla two-hour Megapack system.

It is anticipated that the project would allow the substitution of fossil fuels with renewable power while also providing balancing services to the electrical grid network in the United Kingdom.
This connection point is planned for phases "A" and "B" of the Dogger Bank wind farm, which is scheduled to begin operations the following summer. The property in question is located near the Creyke Beck substation owned by National Grid.

Tesla oversaw all aspects of the development of the Pillswood project. Initially, it was anticipated that the project would enter operation in two stages, in December 2022 & March 2023, respectively. The schedule was sped up so that both phases could be energized in November, just in time to assist National Grid in its attempts to deliver consistent and secure electricity to families in the United Kingdom during what is anticipated to be a brutal winter.

Because of Russia's continuous aggression against Ukraine, the natural gas supply has been disrupted throughout Europe, which has a knock-on effect on energy generation across the continent.

The project will be overseen by Autobidder, Tesla's algorithmic trading platform. Autobidder has previously handled the Holes Bay and Contego projects, two different battery storage facilities that Harmony Energy Limited, in partnership with FRV, also created. Autobidder will be used to administer the project.

According to Harmony Energy Income Trust, Pillswood is the first of six comparable projects the Trust will deliver in the following year.
