Energy / New battery storage system will help to lower power station’s carbon footprint
A NEW energy storage system is set to be installed at Lerwick Power Station, with hopes that it will bring a “significant reduction” in emissions at the diesel-powered facility.
The Wärtsilä battery system is expected to be delivered by mid-summer before becoming fully operational in September.
The 8MW/6MWh system will provide grid balancing and back-up capabilities, and give increased stability to “enable existing wind turbines greater penetration onto the electricity grid”.
A spokesperson for SSE said the benefit of renewable contribution to the network through the energy storage system means a reduction in the use of diesel generation.
It is estimated that the battery will reduce fuel consumption by 1,000 tonnes and overall CO2 emissions from Lerwick Power Station by five per cent annually.
The investment from SSEN comes ahead of Shetland being connected to the national grid by a transmission link, which is expected in 2024. The ageing power station is set to close around this time.
