Nuclear power plants around the world generated 2,553 TWh of electricity in 2020, a drop of 104 TWh from 2019’s total, according to World Nuclear Performance Report 2021. The report was released last week by the U.K.-based World Nuclear Association.
Nuclear generation declined in Africa, North America, and Western and Central Europe, rose in Asia (but by much less than in recent years), and remained largely unchanged in Eastern Europe, South America, and Russia, the 68-page report states.
Sama Bilbao y León, WNA director general, notes in the report’s preface that although the nearly 4 percent decline “would be an unequivocal disappointment” in any other year, “in 2020, with overall electricity demand falling by around 1 percent and nuclear reactors increasingly being called upon to provide load-following support to the increased share of variable renewable generation, the resilience and flexibility shown by the global nuclear fleet tell a very positive story.”

Nuclear energy is faced with a number of challenges in a changing energy landscape, driven by the need to reduce carbon emissions to mitigate climate change. Renewable energy technologies are being considered as the solution to climate change and are increasingly being deployed across the world. However, renewable energy sources, particularly solar and wind, are highly variable, and deployment of these technologies has resulted in significant perturbances in the energy market, raising questions about grid stability and the adaptability of other sources to compete in a changing marketplace that prioritizes renewables. Nuclear plants, well suited for baseload operation, have demonstrated technical capability and flexibility to respond to the fluctuating demand; however, they have also discovered that the economics of such operating mode are not necessarily optimal to their financial security. On the other hand, despite contributing to the carbon emissions, the low cost of abundantly available natural gas and resultant low-cost electricity have exacerbated the economic pressure on nuclear technologies, raising questions about their survival and role in future energy systems1.

Significant discussions have occurred recently on various internet venues about "load following"-that is, the capability of a generating source to adjust its power output to match variable demands. There is a myth spreading that nuclear power plants cannot load follow, and today's ever-changing discussion about low-GHG generating sources demands that this myth be dispelled.
