Overview
Stornoway is a 24 MW diesel power plant in the Outer Hebrides, Scotland, operated by Scottish and Southern: Island Generation. It provides essential electricity to the Isle of Lewis.
Stornoway is a diesel power plant located near Stornoway on the Isle of Lewis in the Outer Hebrides, Scotland. With a capacity of 24 MW, it is a medium-scale facility within the UK's diesel generation sector, primarily serving the local island grid. The plant is owned and operated by Scottish and Southern: Island Generation, a subsidiary of SSE. The plant uses oil as its primary fuel, typical for island-based diesel generation where grid interconnection is limited. Diesel plants in the UK operate under the Environmental Permitting Regulations, which implement the EU Industrial Emissions Directive. Best Available Techniques (BAT) for medium combustion plants apply, including emission limits for SOx, NOx, and particulates. Older diesel plants may have higher emissions per MWh compared to modern CCGT. Stornoway plays a critical role in ensuring energy security for the Isle of Lewis, which has limited interconnection to the mainland grid. Its operation supports local communities and businesses, particularly during peak demand or when renewable sources like wind are low. The plant's environmental impact is managed through regulatory compliance and potential future integration with renewable energy storage.
Environmental context
The plant's diesel combustion emits CO2, SOx, NOx, and particulates, contributing to local air quality concerns, especially given its proximity to populated areas. The Outer Hebrides have sensitive ecosystems, including peatlands and coastal habitats. Emissions are regulated under UK law, and the plant may be subject to carbon pricing. Its relatively small capacity limits regional impact, but fuel transport to the island adds logistical emissions.
