Reaching Net Zero Carbon in Great Britain

This technical report evaluates the pathways required for Great Britain to achieve its net zero carbon target by 2050, as mandated by the 2008 UK Climate Change Act. The report outlines the necessity for significant investments in lower carbon generation and grid infrastructure throughout the current decade. It details various scenarios for the expansion of renewable energy sources, including offshore wind, solar, and battery storage, while also addressing the role of nuclear and gas power in maintaining grid reliability. The analysis emphasizes the urgent need for policy reforms to incentivize investment in these technologies and enhance grid capacity to accommodate the expected doubling of electric demand by 2050. Furthermore, the report discusses the implications of locational constraints on generation resources and the importance of transmission upgrades to prevent curtailment of renewable energy. The findings underscore that a multifaceted approach combining diverse energy sources and supportive regulations is essential for meeting the ambitious decarbonization goals.
