Hornsea 3 Battery Energy Storage To Start Operations Next Year, Ørsted Selects Arenko’s Platform to Operate BESS

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

Arenko has been selected by Ørsted to deploy its Nimbus optimisation, asset management and trading platform at the 300 MW/600 MWh Iceni battery energy storage system (BESS) that will be part of the 2.9 GW Hornsea 3 offshore wind farm in the UK. The BESS project is scheduled to enter operations in the first quarter of 2027.

These are the first three paragraphs.

Named Iceni, the battery storage project is being developed as one of the UK’s first large-scale co-location projects under the Offshore Transmission Network Review (OTNR).

Iceni is designed to share transmission infrastructure and an onshore grid connection with Hornsea 3, rather than securing a separate grid connection. According to Arenko, this makes it the world’s first utility-scale battery to be directly integrated into offshore transmission infrastructure.

Under the agreement with Ørsted, Arenko’s Nimbus software will be used to forecast market and asset conditions, determine how battery capacity should be allocated in real time and automate trading across power markets. The platform will also support the technical, data and controls integration required to operate the battery alongside the offshore wind farm through their shared connection.

Note.

The Offshore Transmission Network Review (OTNR) has a web site.

The Hornsea 3 wind farm has a capacity of about ten times that of the battery.
