Tohoku Electric Power

Tohoku Electric Power Co., Inc. is a publicly listed company headquartered in Japan. In 2019, its revenue was US$20.6 billion and installed capacity was 26.94 GW in 2018. It is the fourth-largest electric utility in Japan in terms of revenue, servicing 7.6 million individual and corporate customers in six prefectures. Tohoku will drive significant emissions reductions in the near-term thanks to nuclear re-starts, but the company's ambition for long-term decarbonisation is lacking.

Risks and opportunities


Tohoku is awarded a trend score of =. If the company were reassessed in the near future, its score would likely stay the same. In the short term, the restarting of four nuclear assets with a combined capacity of ~3.5 GW (13% of total 2018 installed capacity) will drive reductions in Tohoku’s emissions intensity. However, the company is expected to exceed its decarbonisation budget in the long term because of its projected ongoing reliance on fossil fuels. Tohoku does not have clear growth plans or investment strategies for its low-carbon business models. While it has stated an intention to develop 2 GW of wind capacity, no timeline is provided for this target.
