We will work to reduce the volume by replacing all company-owned vehicles with EVs, PHVs and HVs by 2030. These exclude special vehicles for emergency and construction purposes, which are not suited for electrication. Meanwhile, CO2 emissions related to the procurement of retail electricity from other companies make up most of Scope 3 emissions. Our target is to reduce these emissions by 50% by FY2030 from the FY2013 level (about 64.69 million tons). In FY2020, the gure was down to around 41.74 million tons as a result of the increased use of renewable energy and procuring electricity from high-efciency thermal power plants. We will continue to undertake efforts, including further expanding the use of renewable energy, toward achieving the target.(1) Number of customers served in markets subject to renewable portfolio standards (RPS) and (2) percentage fulllment of RPS target by market2QuantitativeNumber, Percentage (%)IF-EU-110a.4(1) N/A; (2) N/A* Japan’s RPS law that set out RPS regulations was abolished in 2012, and we have shifted to a feed-in tariff system.* We purchase electricity generated by renewable energy at a xed price.Air QualityAir emissions of the following pollutants: (1) NOx (excluding N2O), (2) SOx, (3) particulate matter (PM10), (4) lead (Pb), and (5) mercury (Hg); percentage of each in or near areas of dense populationQuantitativeMetric tons (t), Percentage (%)IF-EU-120a.1(1) 79 [t]*1; (2) Not disclosed*2; (3) Not disclosed*3; (4) Not disclosed*3; (5) Not disclosed*3*1: Chubu Electric Power transferred its thermal power generation business to JERA in April 2019. Also, the gure does not include the Kamishima Internal Combustion Power Plant, which is for emergency use.*2: Not disclosed because we do not use the measurement method recommended by the SASB standard for applicable plants, including the Yokkaichi Biomass Power Plant. We have conrmed that it does not exceed the standard gure specied in advance in an agreement with the corresponding local governments.*3: Not disclosed because we do not use the measurement method recommended by the SASB standard.Water Management(1) Total water withdrawn, (2) total water consumed, percentage of each in regions with High or Extremely High Baseline Water StressQuantitativeThousand cubic meters (m3), Percentage (%)IF-EU-140a.1(1) 50,584,856 [1,000 m3], 0 [%]* Main applications: For hydropower generation, for the biomass power plant and for maintenance of the nuclear power station(2) 86 [1,000 m3], 0 [%]Number of incidents of non-compliance associated with water quantity and/or quality permits, standards, and regulationsQuantitativeNumberIF-EU-140a.20Description of water management risks and discussion of strategies and practices to mitigate those risksDiscussion and Analysisn/aIF-EU-140a.3We assess water-related risks separately for nuclear power generation, hydroelectric power generation and biomass power generation. This is because our nuclear power station, hydroelectric power plants and biomass power plant are respectively located in a seashore area, in mountain areas and in an area where fuels are conveniently available, and because we need to consider the natural environment surrounding each plant and social situations. As for nuclear power generation, we had conventionally implemented facility designs and countermeasures in accordance with the national regulatory standards that take into consideration earthquakes, tsunamis and other natural disasters. The new regulatory standards, which were issued following the earthquake off the Pacic coast of Tohoku in 2011, changed the maximum height of tsunamis affecting nuclear power plants to 21.1 meters. In response, we have implemented various measures, such as installing wave protection walls that are 22 meters above sea level and raising the embankment surrounding our station to a maximum height of 24 meters. As for biomass and hydroelectric power generation, an assessment using Aqueduct, the World Resources Institute’s (WRI) Water Risk Atlas tool, revealed that annual maximum water risk for our plants is Low to Medium, with some located in Low risk areas. Under national guidelines, all of our hydroelectric power plants discharge water as necessary to maintain the ow rate specied for each river. Depending on watershed areas, we also suppress an increase in downstream ood water by constructing dams with spillway gates and adjusting the volume of water discharged from these dams.Coal Ash ManagementAmount of coal combustion residuals (CCR) generated, percentage recycledQuantitativeMetric tons (t), Percentage (%)IF-EU-150a.1N/A [t]; N/A [%]Total number of coal combustion residual (CCR) impoundments, broken down by hazard potential classication and structural integrity assessmentQuantitativeNumberIF-EU-150a.20Energy AffordabilityAverage retail electric rate for (1) residential, (2) commercial, and (3) industrial customersQuantitativeRateIF-EU-240a.1(1) 19.98 [JPY]; (2) 13.07 [JPY]; (3) 11.15 [JPY]* Excluding consumption tax and shared charge imposed under the renewable energy feed-in tariff system and including fuel cost adjustment chargeTypical monthly electric bill for residential customers for (1) 500 kWh and (2) 1,000 kWh of electricity delivered per monthQuantitativeReporting currencyIF-EU-240a.2(1) 13,114 [JPY]; (2) 26,771 [JPY]* Calculated using an “Otoku” plan (special rate plan) for 40-ampere contracts.Number of residential customer electric disconnections for non-payment, percentage reconnected within 30 daysQuantitativeNumber, Percentage (%)IF-EU-240a.3(1) 147,834; (2) Number reconnected: 129,021* Number reconnected because bill payment is conrmed within 15 days of the date of the disconnectionDiscussion of impact of external factors on customer affordability of electricity, including the economic conditions of the service territoryDiscussion and Analysisn/aIF-EU-240a.4According to Japan’s Electricity Business Act, “A General Electricity Utility shall not refuse to supply electricity to meet general demand in its service area (excluding, however, demand at the Point of Business Commencement and Specied-Scale Demand) without justiable grounds.” As a general rule, we supply electricity if we receive a request to do so within Chubu Electric Power Grid’s service area. We thus believe that every consumer is given the same opportunity to obtain energy at an affordable price and that no district within our service area is without electricity. We also recognize that external factors that impact electricity rates are shared charge imposed under the renewable energy feed-in tariff system and fuel cost adjustment charge that reects uctuations in the price of thermal power fuels. SASB INDEXThe table below outlines the achievements and status of the initiatives of the Chubu Electric Power Group based on the standard developed by the Sustainability Accounting Standards Board (SASB) for the Electric Utilities & Power Generators industry. Since the SASB standard was created for primarily companies and markets in the United States, it includes accounting metrics that do not apply to business activities in Japan. Nonetheless, we have made efforts to disclose as much information as possible.Top CommitmentValue CreationClimate ChangeStrategyBusiness ActivitiesGovernanceHuman ResourcesFinancial / Corporate Data81Chubu Electric Power Group Report 2021
