Arenko’s optimal performance

1 March 2023

Arenko has signed a second contract with Vattenfall to optimise a new co- located 20 MW/45.5 MWh battery asset in Northumberland, north east England.

The award of this contract follows on from a previous contract to optimise Vattenfall’s 22 MW/16 MWh battery co-located at the 228 MW Pen y Cymoedd wind farm in South Wales.

The asset will utilise Arenko’s cloud- based software, Nimbus, which forecasts market and asset conditions, performing millions of simulations per day to optimise trading decisions and asset performance across markets, and then to securely and autonomously dispatch stored energy from the asset.

Arenko says it is the “top performing battery optimiser in UK”, delivering an additional £1 million of revenue per annum vs competitors for every 50 MW of battery capacity in the period January to October 2022 (annualised battery return of £168k per operational MW per year).

Batteries optimised by Nimbus captured 8% higher revenue than the closest competitor optimiser, and generated a 14% higher battery return than the industry average, the company says, based on an analysis of the performance of every operational battery in the UK, using data from Elexon, National Grid, and EPEX.
