UK firm Anesco says it is on track to more than quadruple its operational battery portfolio by 2020.

Anesco has announced that its order book for energy storage systems in the UK has grown to 380 MW and that it has several large-scale projects under construction.

Anesco currently has 29 operational sites comprising 76 individual battery units in the UK, providing combined capacity of 87 MW. Its projects account for 22 per cent of all operational utility-scale storage capacity in the UK.

Its projects under construction include a 50 MW batter energy storage system in Hampshire, southern England, which is due for completion in 2018.

Steve Shine, executive chairman of Anesco, said: “We have long recognised the potential and importance of battery storage for the UK’s energy mix and have invested heavily in making sure it is a commercially viable option for investors and commercial organisations alike.”

He continued: “Having the ability to show how the figures stack up is crucial and has been a key differentiator for us. As the largest and most established provider in the country, we are in a unique position to analyse data from all our existing battery sites, which we’ve combined with a comprehensive data set from energy market analysts Cornwall Insight.

“This has enabled us to create the most accurate modelling tool available, meaning we can predict whole life cost, IRR and long term revenue streams – the numbers that really count. Our batteries are performing above specification and are delivering a strong economic return for our customers.”

Anesco opened the UK’s first subsidy-free solar farm at Clayhill in September 2017. The project is co-located with a 6 MW battery storage facility.

Shine added: “We remain the first and only company to offer retrofit co-location with existing solar farms and are the only UK company to achieve subsidy-free solar. Our experience, combined with this strong track record, puts us in a great position moving forward.”
