Tohoku Electric Power Co Inc

Tohoku Electric Power Co., Inc. operates a generation fleet that is heavily reliant on fossil fuels, with coal-fired power plants constituting a significant portion of its electricity output. According to its 2024 Sustainability Data Book, fossil fuel-based thermal power accounted for approximately 60% of its total power generation in fiscal year 2023. This reliance places the company's emissions intensity among the highest within its regional utility peer group in Japan. The company's disclosed greenhouse gas emissions for Scope 1 and 2 totaled over 30 million metric tons of CO2 equivalent for the same period.

While the company has announced a "Carbon Neutral Challenge 2050" target, its current operational strategy continues to prioritize coal and liquefied natural gas (LNG) for baseload power. Its near-term plans include maintaining and operating existing coal-fired units, with only a gradual introduction of renewable energy sources. This trajectory indicates a systematic failure to reduce emissions intensity at a pace aligned with the urgency of the climate crisis, as evaluated against sector benchmarks for decarbonization.

Tohoku Electric Power Co Inc operates the Fukushima Daini Nuclear Power Station, located approximately 12 kilometers south of the Fukushima Daiichi plant. Following the 2011 earthquake and tsunami, the Daini plant also suffered a loss of cooling capability, leading to a heightened risk of a severe accident and widespread environmental contamination. While the company avoided a full-scale meltdown, the event resulted in documented environmental releases and necessitated long-term management of contaminated water and materials. The incident underscores the persistent environmental risks associated with nuclear power generation in seismically active regions.
