For realization of an environment-friendly society

Efforts for wider use of renewable energy

 Hokuriku Electric Power Group has put a lot of work into introduction of renewable energy including hydroelectric power, wind power, photovoltaics and biomass.

Efforts for deployment of low-carbon generation resources

 Hokuriku Electric Power Group actively makes efforts to reduce carbon emissions of generation resources such as resumption of operation of Shika Nuclear Power Station, new installation of LNG-fired power plants, wider use of renewable energy. Also, our group strives to encourage our customers to use energy more efficiently by offering highly efficient equipment which contribute to energy saving and works to reduce CO2 emissions.
 In February 2016, the Federation of Electric Power Companies of Japan including Hokuriku Electric Power Company and a voluntary group of Specified-Scale Electricity Utilities (Shindenryoku) formed the Electric Power Council for a Low Carbon Society (hereinafter referred to as "ELCS") to promote electricity industry-wide efforts for realization of a low carbon society.
 ELCS aims to steadily facilitate the work for achievement of "ELCS's Low Carbon Society Action Plan" and sets a target to attain an emission intensity of about 0.37 kg-CO2/kWh in FY2030.
 Hokuriku Electric Power Company will further endeavor to realize a low carbon society as a member of ELCS.

Note: The customers who consume electricity produced by our company should use "actual CO2 emission intensity" in calculation of "greenhouse gas emissions" to report their emissions to the government under the "Act on Promotion of Global Warming Countermeasures" (Global Warming Act) and should use the "adjusted CO2 emission intensity" in calculation of "adjusted greenhouse gas emissions."

Hydroelectric power generation

Replacement of hydraulic turbine runner We have increased the power production of our hydroelectric power stations since FY2009 through new installation of four ecological discharge hydroelectric power stations which use river maintenance discharge and equipment refurbishment such as replacement of hydraulic turbine runners at the existing 28 hydroelectric power stations.
 In April 2016, Hokuriku Electric Power Group started operation of Katakai Betsumata Power Station (Uozu-shi, Toyama), new development of our conduit
type power station for the first time in the past 27 years.

 In FY2016, we further expanded the target amount of electricity produced from "100 million kWh/year by FY2020 (in comparison with FY2007)" to "130 million kWh/year."

Wind power generation and photovoltaics

 Hokuriku Electric Power Company has started photovoltaic power generation projects from 2011 to take a leadership role for realization of a low carbon society and further dissemination of photovoltaic power generation in the Hokuriku region.
 Also, as for wind power generation, the Nihonkai Power Generating Company, one of our group companies, built Fukura Wind Power Station in Fukura district, Shika-machi, Ishikawa prefecture for the first time and took over wind power generation facilities from Ishikawa prefecture and others for enhanced promotion of renewable energy.
 At present, the Nihonkai Power Generating Company is in the process of building Mikuni Wind Power Station in Technoport Fukui (Mikuni-cho, Sakai-shi, Fukui).

Woody biomass co-fired power generation

 Unit 2 of Tsuruga Thermal Power Station started woody biomass co-fired power generation from 2007 and Unit 2 of Nanao Ohta Thermal Power Station also started woody biomass co-fired power generation from 2010.
 We will steadily expand woody biomass co-firing in our thermal power stations.
