IF-EU-110a.3 Discussion of long-term and short-term trategy or plan to manage Scope 1 emissions, emissions reduction targets, and an analysis of performance against those targets Discussion and Analysis - The TEPCO Group’s Scope 1 emissions are very small at only 205,000 t-CO2 since we transferred our fuel/thermal power generation business to JERA in April 2019. On the other hand, our greenhouse gas emissions from the retail sale of power, which account for most of our Scope 3 emissions, must be calculated and reported in accordance with the Act on Promotion of Global Warming Countermeasures. Therefore, the TEPCO Group aims to reduce CO2 emissions originating from the sale of power by 50% of FY2013 levels by the year FY2030. In FY2013, CO2 emissions were 139.2 million tons, but emissions in FY2022 were approximately 65.1 million tons, which is approximately 53% reduction, thereby achieving our target.
* FY2022 CO2 emission figures 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 - We ,the TEPCO Group, operate hydroelectric power stations and more than 200 locations on Japan’s Honshu Island, and the power generated by these stations accounts for approximately 90% of all of our power. The use of natural water resources is indispensable for hydroelectric power, which is a clean source of power that does not produce CO2 during the generation process, so we engage in the following risk management efforts.
Along with discharging the necessary amount of water needed to maintain the environments downstream of the hydroelectric power station dams/weirs, we also comply with our legally obtained water license when taking in water from the river for power generation purposes. Furthermore, when river levels are expected to rise due to torrential rains, we discharge water from the dam in advance in accordance with flood control agreements signed with the Government thereby playing an important role in mitigating damage from torrential rains and contributing to regional preparedness. We use a tool called the “WRI Aqueduct Water Risk Atlas“ to identify water risks and an examination of water stress in the siting locations of our facilities has yielded the following results.
According to the “Baseline Water Stress”, the water stress of the areas in which we conducts its business is “Medium-high” at worst, and there are no hydroelectric power stations in water-stressed areas, so the frequency of water-risks, such as droughts, etc., has been predicted to be low. Results from the future water stress test suggested that water stress will not change going forward. However, we will continue to strive to manage risks by implementing risk-assessments of the actual water usage status in power station siting locations, as well as specific rivers and basins, while referring to these results.
Going forward, we shall examine long-term strategies to address the impact on the our facilities from physical risks, such as flooding, etc. caused by climate change.

Shown as "No results" since supply suspension and resumption are not stipulated in the Terms and Conditions.
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 group.
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)
