The National Energy System Operator (NESO) has been assigned by the UK, Scottish, and Welsh Governments to develop the first Strategic Spatial Energy Plan (SSEP) for Great Britain. This plan will encompass national planning for electricity and hydrogen, focusing on identifying optimal locations for these assets. NESO will start by creating and consulting on the methodology for the SSEP, conducting economic modeling to pinpoint cost-effective locations for future energy infrastructure. Community input will influence the outcomes to ensure alignment with energy security, decarbonization, and environmental considerations. The SSEP will offer various pathway options for the future energy system and serve as a blueprint for energy planning in Great Britain. Ultimately, the plan aims to expedite the transition to clean and affordable energy by fostering engagement with communities, industry, investors, and consumers for a reformed energy system. Collaboration with stakeholders like The Crown Estate and Crown Estate Scotland will be crucial for the success of the SSEP, which will be interconnected with other NESO plans and roles. The positive sentiment is evident through statements from key figures like Kayte O’Neill and Gus Jaspert, emphasizing the importance of the SSEP in shaping the future energy landscape and supporting the energy transition.
