SP Energy Networks has embarked on the latest phase of its “Blade” project, focusing on enhancing Britain’s energy security through innovative grid restoration methods utilising renewable resources. This initiative involves collaboration between Scotland’s two transmission companies, SP Energy Networks and SSEN Transmission, alongside wind farm operators such as SSE Renewables and Ørsted, and the National HVDC Centre.
Traditionally, hydro generators are the primary choice for restarting the grid after a national power outage, as they can independently generate electricity. These generators initiate the process, enabling other power sources like gas stations and wind farms to gradually restore power. However, diversifying grid restoration methods is crucial. The Blade project aims to explore the potential of offshore wind farms in this context, providing the National Energy System Operator (NESO) with additional options.
The project will be trialled in a specialised laboratory setting, simulating real-life scenarios. This collaboration includes manufacturers, developers, and transmission companies, all working towards the potential deployment of these methods across the UK’s offshore wind farms. Eddie Mulholland, Director of Processes and Technology at SP Energy Networks, emphasised the project’s significance, stating it could transform not only the GB grid but also electricity networks globally. He highlighted the importance of evolving technology to ensure a resilient grid capable of restarting during emergencies.
Building on the success of the Distributed ReStart project, Blade continues to demonstrate the feasibility of using small-scale generators for grid restoration. The project also draws insights from The Carbon Trust’s Offshore Wind Accelerator programme, with funding support from the Strategic Innovation Fund, managed in partnership with Innovate UK. An extensive industry consortium, including SP Energy Networks, SSEN Transmission, TNEI, the National HVDC Centre, and several international partners, is dedicated to advancing this initiative over the next three years.
