Spanish company Ingeteam is to supply a 50 megawatt-hour battery storage system to be installed at ScottishPower Renewables’ 539MW Whitelee wind farm at Eaglesham Moor, south of Glasgow.
Ingeteam will provide the battery, alongside the control system and the power converters, ScottishPower said.
The plant is expected to come online at the end of 2020, with testing to ensure compliance with the grid code due to be completed in the first quarter of 2021.
Plans for the battery were approved by the Scottish government in June 2019.
The energy storage system will be used for a number of different applications, with its main use to be as a back-up for the wind farm to allow it to better manage the energy delivered to the grid.
It will also allow SPR to take part in the UK’s frequency regulation market.
The battery will mean that during troughs in demand, Whitelee can continue to generate at peak capacity, with the surplus charging the battery.
This can then be discharged when the demand is higher than the generating capacity, helping Whitelee to make up any shortfall.
The choice of Ingeteam to provide the battery comes after ScottishPower parent company Iberdrola made an agreement with the company for the supply of inverters for its Francisco Pizarro solar PV plant.
