Nuclear Electricity Market Report 2026

The nuclear electricity market size has grown steadily in recent years. It will grow from $279.16 billion in 2025 to $289.48 billion in 2026 at a compound annual growth rate (CAGR) of 3.7%. The growth in the historic period can be attributed to expansion of large-scale nuclear power capacity, long-term investment in baseload electricity generation, development of generation II and III reactors, government-backed nuclear programs, growing electricity demand from industrial sectors.

The nuclear electricity market size is expected to see steady growth in the next few years. It will grow to $343.06 billion in 2030 at a compound annual growth rate (CAGR) of 4.3%. The growth in the forecast period can be attributed to expansion of generation IV reactor development, rising deployment of small modular reactors, increasing grid decarbonization targets, growing investments in nuclear safety technologies, rising demand for stable low-carbon electricity. Major trends in the forecast period include increasing deployment of advanced reactor designs, rising focus on life extension of nuclear plants, growing adoption of safety and monitoring upgrades, expansion of small modular reactor projects, enhanced emphasis on low-carbon baseload power.

The rising demand for electricity is expected to be a major factor driving the nuclear power generation market during the forecast period. This growth is linked to expanding economies and increasing populations, particularly in developing nations such as China, India, Brazil, and several African countries. For example, in December 2025, the U.S. Energy Information Administration (EIA), a U.S. government agency, reported that total U.S. electricity consumption is projected to reach 4.19 trillion kilowatt-hours (kWh) in 2025, up from 4.11 trillion kWh in 2024 - a 2.1% increase driven by higher residential, commercial, and industrial usage. Therefore, the growing demand for electricity is contributing to the expansion of the nuclear electricity market.

The increasing use of microgrids is also expected to support the growth of the nuclear electricity market in the coming years. A microgrid is a localized energy network that can operate independently or alongside the main power grid. Microgrids play an important role in integrating and optimizing AI technology in the energy sector by enabling intelligent energy management, grid optimization, and the incorporation of renewable energy sources. They assist with demand response, load balancing, and renewable energy integration. For instance, in September 2024, a report from the Department of Energy Security & Net Zero, a UK government department, noted that net electricity imports rose by 21% from Q2 2023 to reach 9.2 TWh, representing 13% of the UK’s electricity demand in Q2 2024. Therefore, the expanding adoption of microgrids is expected to further drive growth in the nuclear electricity market.

Companies in the nuclear electricity market are prioritizing the development of next-generation nuclear reactor technologies, including small modular and advanced reactors, to accelerate clean and reliable power generation, strengthen energy security, and support decarbonization objectives. These advanced reactors incorporate innovative designs and enhanced safety systems to improve efficiency, reduce waste, and allow flexible deployment. For example, in August 2025, the U.S. Department of Energy (DOE), a U.S.-based government agency, launched its Nuclear Reactor Pilot Program in collaboration with 11 advanced reactor projects - including organizations such as Oklo Inc. and Terrestrial Energy Inc. - to build, operate, and achieve criticality of test reactors. The program aims to speed up commercial licensing, encourage private investment, and facilitate the deployment of safe, efficient, and carbon-free nuclear energy solutions.
