| IF-EU-110a.3 | Discussion of long-term and short-term strategy or plan to manage Scope 1 emissions, emissions reduction targets, and an analysis of performance against those targets | Discussion and Analysis | - |
The TEPCO Group has set a target of reducing CO₂ emissions from electricity sales¹ by 50% by fiscal 2030 (compared to fiscal 2013²) and achieving virtually zero CO₂ emissions from energy supply by 2050. These targets also include Scope 1 emissions.
Through initiatives such as building an optimal procurement portfolio that includes non-fossil power sources, we are committed to both “stabilizing electricity prices” and “achieving CO₂ reduction targets.” CO₂ emissions, which were 139.2 million tons in fiscal 2013, have been reduced by 44% to 78 million tons*³ in fiscal 2024 through measures such as improved power procurement and the purchase of non-fossil certificates. *1 CO₂ emissions associated with electricity sold by TEPCO Energy Partner (EP), including Scope 1 (e.g., EP vehicle use), Scope 2 (e.g., electricity use in EP offices), and Scope 3 (emissions from electricity delivered to customers). *2 For Scope 1 and 2, the comparison is with fiscal 2019. *3 FY2024 CO₂ emissions are preliminary figures. |

| IF-EU-140a.3 | Description of water management risks and discussion of strategies and practices to mitigate those risks | Discussion and Analysis | - |
The TEPCO Group operates hydroelectric power plants in more than 200 locations in Honshu, Japan, and the amount of power generation accounts for about 98% of the total. The use of water resources is essential for a clean hydroelectric power generation business that does not emit CO₂ during power generation, and the following risk management is carried out.
At dams and downstream of embankments at hydroelectric power plants, the water necessary to maintain the environment of the river is discharged, and the amount of water withdrawn from the river for power generation complies with the amount of water intake permitted by law. In addition, when river flooding due to heavy rain is expected, water will be discharged in advance from the dam based on the flood control agreement with the national government, and it plays an important role in reducing heavy rain damage in regional disaster prevention. The results of verifying water stress in the area where our facility is located by using “WRI Aqueduct Water Risk Atlas” tool to identify water risk are as follows. According to the "Baseline Water Stress", water stress is "Medium-high" at the maximum in the business area of the TEPCO Group. So there are no facilities such as hydroelectric power plants in water-stressed areas, and it is assumed that the frequency of water-related risks such as drought is low. In "Future Water Stress", there is a suggestion that water stress may not change a lot. However, with reference to this result, we will carry out risk assessment based on the actual water usage conditions at specific rivers and basins, as well as at power plants locations, and will continue to strive for risk management. In the future, we will consider long-term strategies regarding the impact of physical risks on our facilities such as floods due to climate change. |

| IF-EU-240a.4 | Discussion of impact of external factors on customer affordability of electricity, including the economic conditions of the service territory | Discussion and Analysis | - |
According to 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 Specified-Scale Demand) without justifiable grounds." Thus, we do not recognize there are any areas without electricity in all the service areas of the TEPCO Power Grid.
We also recognize that external factors which impact electricity rates are fluctuations in the price of thermal power fuels and levies from the Feed-in-tariff law for renewable energies.(price based regulations: requires electricity companies to purchase renewable energy at a certain price) |
