In this article, we will be taking a look at the 20 biggest power generation companies in the world. To skip our detailed analysis, you can go directly to see the 5 biggest power generation companies in the world.
Consistent generation and supply of power is absolutely integral to the development of any economy, and is one of the primary factors behind industrialization and the growth of Western economies. While just the 20 biggest power generation companies in the world earn annual revenues exceeding $2 trillion, their indirect contribution is even more significant as power supply is the backbone for the vast majority of industries across all sectors, across the world.
Despite its importance, 2022 was not a very good year for the power and utility sector generally, but in the U.S., sales still continued to increase as demand jumped with the country mostly recovering from the Covid-19 pandemic. However, even though revenues increased significantly because of the aforementioned demand, costs increased even more as a result of the Russian invasion of Ukraine, which led to energy supplies being depleted and prices more than doubling. Meanwhile, grid resilience is continuing to be tested from catastrophic climate events, one of the biggest global risks for 2023. To combat this issue, the biggest players in the industry, including some of the biggest power generation companies in the world, improved their reserves, deployed microgrids and worked on improving their infrastructure as well.

While these developments are likely to increase further in 2023 and even beyond, it is important to remember that as the Russian Ukraine war continues with no idea of when hostilities will cease, electricity prices are likely to stay high in 2023 while inflation and supply chain issues will add to the challenges that the industry is facing right now. Other issues such as extreme weather events and even cybersecurity will require innovation to ensure that power generation and its supply remains stable.
As is true for most industries, the investment viability of the biggest power generation companies in the world doesn't just depend on revenue and profits but Environmental, Social and Governance (ESG), which is continuing to gain momentum, especially with regards to decarbonization practices as companies try to identify societal and environmental disrupters while focus on resolving them. While such disclosures in the U.S. aren't uniform across power generation companies, this will also change in 2023, after a new SEC proposal in March 2022 regarding certain public disclosures.
Another important consideration for the power generation industry is the requirement of a shift from using non-renewable resources to renewable resources. Companies creating clean energy have a lot of incentives, grants and subsidies from the government. This is why NextEra Energy, Inc. (NYSE:NEE), the biggest renewables energy company by market cap, is also the biggest power generation company by market cap. According its Q4 2022 earnings call, NextEra Energy, Inc. (NYSE:NEE) CEO stated "In short, we believe the IRA provides growth visibility for a broad range of low-cost, clean energy solutions in a predictable way and for a long time. We believe that in this environment, low-cost renewables will help NextEra Energy and NextEra Energy Partners continue to drive long-term value for our customers and our shareholders and unitholders." This just helps signify the important of renewable energy production in this industry.
