Challenges of TEPCO

  1. Energy & Resources

Ukishima Solar Power Plant

Ohgishima Solar Power Plant

Komekurayama Solar Power Plant

* The temperature and the insolation intensity provided in the contents are used to check the installation environment of the solar panel and the electric power generation status, and are not representative of the region.
 

Renewable energy

Renewable energy is energy that has a smaller impact on the environment, such as solar, wind and hydro power. TEPCO has been introducing power generation facilities that leverage renewable energy and has met the quota under the Act on Special Measures Concerning New Energy Use by operators of electric utilities (Renewable Portfolio Standard [RPS] Act).*

*This act requires retail electric utilities to ensure that a specified percentage of electricity they sell is produced from renewable energy sources defined by law.

 

Solar power generation (large solar power generation)


Ukishima Solar Power Plant (Kanagawa)
Our first commercial solar power plant (large solar power plant) came into operation in Ukishima, Kawasaki City, Kanagawa Prefecture, in August 2011, and another did in December 2011 in Ohgishima, Kawasaki City. In 2012, TEPCO came into operation another large solar power plant in Komekurayama, Kofu City, Yamanashi Prefecture. Together these three power plants provide a maximum output of 30,000 kW.

Hydro (small hydro) power generation


Tsugane Hydro Power Station (Yamanashi)
TEPCO owns hydro power stations with a total output of approximately 8,980 MW and is seeking to effectively use them. Our new efforts are underway in the field of hydro power generation, including the construction of "small hydro power stations" with a maximum output up to about 1,000 kW.

Wind power generation


Hachijojima Wind Power Station (Tokyo)
Recent technology advancement in wind power generation has made larger equipment available at lower cost. This has enabled cost-effective power generation under preferable conditions of wind and other factors.
Our Hachijojima Wind Power Station is the first commercial wind power plant built by a Japanese electric utility. It capitalizes on good wind conditions in Hachijojima (Hachijo Island).

Geothermal power generation


Hachijojima Geothermal Power Station (Tokyo)
Hachijojima Geothermal Power Station is TEPCO's first geothermal power station built in Hachijojima. Located within the Fuji-Hakone-Izu National Park, this power plant is designed with emphasis on the conservation of the island's natural environment and harmonization with the local community. It uses geothermal energy while giving utmost consideration to the surrounding environment.
