Top 10 Power Companies in the World

Unprecedented weather changes and effects from COVID may have backtracked the power companies. 2021, though, showed encouraging signs for most of the companies globally.

State Grid Corporation of China–USD386bn

Probably the world’s biggest power company by revenue, the State Grid Corporation of China (SGCC) recorded a revenue of $386bn in 2021 after emerging from the setbacks posed by the pandemic. Headquartered in Beijing, SGCC covers 88% of the Chinese territory. The company has also an active base, operating assets in the Australia, Philippines, Portugal, Brazil, and Italy to name a few.

Electricite de France–USD66.13 billion

One of the most profitable European companies, the France-based EDF or Électricité de France, has had great innings. Their trading revenue alone surged 63% in the first nine months of 2021, racking in $1.3 billion. This had given the debt-laden company some respite, especially with its back and forth with the French government and the European Union regarding regulated prices for its nuclear output.

Top Power Companies in the worldKEPCO-USD53.9bn

The Korean power company had a virtuoso performance despite domestic weather issues. Though their power sales volume and revenues were down by 2.2% and 1.1%, they held substantial ground with a revenue of $53.9bn thanks to their projects in 24 countries. They attribute COVID-19 and a prolonged rainy season during summer in Korea to their negative sales performance.

Exelon Corporation- USD33bn

Exelon Corporation brands itself as America’s leading energy provider. They quote of providing 31,000 megawatts of clean energy to three-fourths of the Fortune 100 companies and residences. Though 2020 brought their overall operational revenue down, they could seize a revenue of USD 33 billion. This Chicago-based electric utility has big plans for the future, which comes along with a separation from Exelon Utilities (RemainCo), and Exelon Generation (SpinCo).


Based on the indicative 2021 first quarter, Engie records earnings before interest, taxes, depreciation, and amortization (EBITDA) of $11.96 billion (€10.6 billion). ENGIE’s integrated business model has enabled the Group to offset the financial impact of weather-related turbulence in the US, Texas. A favorable evolution in power prices in Belgium and France and pleasanter, colder weather in France at the beginning of 2021, has set the company on better grounds. Betting hard on renewables, Energy Solutions, and international networks, ENGIE expects growth investment of between €15 to 16 billion by 2023.

GE Power – USD4.025bn

GE Power’s revenues increased by 3% in 2020. Driven by better cost productivity and a cut in fixed costs, their revenues reached USD4.025 billion. The company had a sales drop of 12%, with orders for 17 gas turbines with 32 orders in 2020, which is less compared to its 2019 list.


Spanish electric utility Iberdrola saw its renewable business boost its net profit by over 270% to EUR 1.28 billion (USD 1.48bn) within the first nine months of 2021. Their reported EBITDA grew by 10% (EUR 5.444mn ), excluding the financial anomalies brought on by COVID. What worked for them is the contribution of additional capacity installed in their onshore and offshore wind farms and an increase in hydro production in Spain.

Siemens- USD2.59bn

Siemens Gamesa continued its positive start to the fiscal year 2021. With both their Offshore and Service businesses picking up, they recorded a 6% YoY to the tune of USD2.59bn. There was also a positive EBIT margin of 4.8%. This time, too, their onshore segment was the star.


Despite the entire group’s consistent efforts to cut costs, TEPCO (Tokyo Electric Power Company Holdings, Inc.,) had its fair share of difficulties. Their fiscal year of 2020 had a net income of  ¥5,866.8bn and faced a loss of 3.0 billion yen because of the nuclear damage compensations. In the fiscal year 2020, the operating revenue of TEPCO was around 5.8 trillion Japanese yen.


The German energy company E.ON had an adjusted EBIT uptick of 14 per cent per YoY and their net income up 19% or roughly $912 million. The company quotes a rise in earnings mainly from their Customers Solutions business. The initial consolidation of VSE in Slovakia, the joint ventures in Turkey and Central Europe have all seemed to pay off.
