R&I Affirms Ratings: 10 Electric Power Companies R&I Changes Outlook to Positive: Co., Inc. R&I Changes Outlook to Stable: The Chugoku Electric Power Co., Inc., Hokuriku Electric Power Co., Hokkaido Electric Power Co., Inc., The Atomic Power Co.

Rating and Investment Information, Inc. (R&I) has announced the following:

SEC. COMPANY NAME CODE 9502 Chubu Electric Power Co., Inc. 9503 The Kansai Electric Power Co., Inc. 9504 The Chugoku Electric Power Co., Inc. 9505 Hokuriku Electric Power Co. 9506 Co., Inc. 9507 Co., Inc. 9508 Co., Inc. 9509 Hokkaido Electric Power Co., Inc. 9513 Electric Power Development Co., Ltd. ---- The Japan Atomic Power Co. * Please refer below for rated bonds, etc. * Tokyo Electric Power Co. Holdings, Inc., Tepco Power Grid, Inc., Jera Co., Inc. and The Okinawa Electric Power Co., Inc. are not included in the scope of this review.

RATIONALE: The creditworthiness of the former general electricity utilities (major power companies) and so forth plummeted in the aftermath of the Great East Japan Earthquake. Since then, it has been recovering at a moderate pace, as the electricity system reform and the business environment for nuclear power generation have developed almost within the range of R&I's assumptions. R&I has affirmed the ratings for the 10 companies listed above, and changed the Rating Outlook for Chubu Electric Power Co., Inc. to Positive and those for The Chugoku Electric Power Co., Inc., Hokuriku Electric Power Co., Hokkaido Electric Power Co., Inc. and The Japan Atomic Power Co. to Stable, reflecting improvements in their earning capacities and financial bases, among others. As regards the electricity system reform, the impact the full liberalization of the electricity retail market and the spin-off of transmission and distribution divisions had on power companies' business bases has been comfortably within the range that was factored into their ratings. Conduct regulations imposed on transmission and distribution divisions do not affect a group's unity. In FY2019 (the year ended March 2020), growth in the market share of Power Producers and Suppliers (PPSs) somewhat slowed nationwide, and transaction volumes in the baseload market, the centerpiece of the government's new measures to promote competition, were very small in the first fiscal year of the market. Following the enactment of the Act of Partial Revision of the Electricity Business Act and Other Acts for Establishing Resilient and Sustainable Electricity Supply Systems in June 2020, the government started to discuss details of the transmission charge system reform. It is considering allowing transmission and distribution divisions to retain part of the cost they have saved. Such factors may positively affect their earning capacities. There remain uncertainties over the prospects for nuclear power generation, as exemplified by the unexpected suspension of plant operation resulting from courts' temporary injunctions. Meanwhile, progress has been made in creating a favorable business environment, particularly through the

NEWS RELEASE

decommissioning accounting system. In July 2020, major power companies, excluding The Okinawa Electric Power Co., Inc., and The Japan Atomic Power Co. submitted applications to the Minister of Economy, Trade and Industry to recover nuclear power-related costs (decommissioning facilitation contributions and compensation contributions) through transmission charges and obtained approval in the same month. Their transmission and distribution subsidiaries will recoup the costs over a long period of time by reflecting in transmission charges the remaining book value of decommissioned plants and payments to a compensation reserve that should have been set aside before the accident at the Fukushima Daiichi Nuclear Power Station. The government's support measures to facilitate nuclear power generation have been steadily put into practice. With respect to environmental, social and governance (ESG) factors, environmental regulations are the most important for power companies. The government began considering introducing new regulatory measures and initiatives to phase out insufficient coal-fired power sources that operate at supercritical or sub-supercritical pressure. Power companies that are more dependent on such power sources will see a greater impact on their supply capacity and cost competitiveness. That said, the government intends to promote a shift to high-efficiency coal-fired power generation by giving due consideration to stable supply and regional circumstances, among others. A decrease in inefficient coal-fired power will also help tighten the supply-demand balance of electricity. R&I will keep a close eye on details of the government's measures, including how power sources to be suspended/closed are specified and when the measures are implemented, as well as companies' supply capacity with their nuclear power sources taken into account. A sound governance structure is indispensable for an electricity business, particularly in gaining local residents' understanding, which supports stable operation of nuclear plants, and maintaining customer bases. The Kansai Electric Power Co., Inc. needs to overhaul its corporate culture and regain the trust that was lost through a graft scandal. Demand for electricity declined in the wake of the novel coronavirus, but bottomed out in May. Given the recent resurgence of infections, however, future developments remain uncertain. Even so, the electricity industry has been less affected than other industries because of its vast customer base. Although power companies' near-term revenue/expenditure will be strained, a significant deterioration in their business bases and financial bases is unlikely.

Chubu Electric Power Co., Inc. Chubu Electric Power Co., Inc. generates relatively stable profits even when its nuclear plants are off-line, because its dependence on nuclear power has been low since before the Great East Japan Earthquake. Upon the integration of its existing thermal power generation business into equity-method affiliate Jera Co., Inc. in FY2019, Chubu Electric Power transferred related debt to Jera, which made its financial profile, one of the strongest among major power companies, even more robust. Jera is expected to make continued profit contributions, given that the government's move to reduce inefficient coal-fired power sources will have only a small adverse impact on the company, whose focus is on liquefied natural gas (LNG)-fired power, as well as that it created a synergy of 25 billion yen in the first year of the integration. Despite lingering uncertainty over the restart of the Hamaoka Nuclear Power Station, it has become more likely that Chubu Electric Power will be able to maintain and continue to strengthen its financial resilience. Based on this view, R&I has changed the Rating Outlook to Positive. R&I will examine electricity sales volumes amid the coronavirus pandemic, developments in the financial burden from growth investments, and their effects on the company's revenue/expenditure and financial position. These factors will be incorporated into the rating.

The Kansai Electric Power Co., Inc. With a power mix that highly relies on nuclear power, The Kansai Electric Power Co., Inc. will be able to demonstrate its cost competitiveness if stable operation is ensured at the four nuclear reactors it restarted by FY2018. The regulatory risk associated with carbon dioxide emission mitigation is relatively low, because the company is not heavily dependent on coal-fired power. Its nuclear capacity factor is expected to be slightly low for the foreseeable future due to a delay in the completion of installing

NEWS RELEASE

Specific Safety Facilities (facilities designed to deal with specific severe accidents; SSFs) at Units 3 and 4 of the Takahama Nuclear Power Station. Confidence in the company's governance was lost through a graft scandal in FY2019. R&I will closely observe the impact on the customer base and any changes in local residents' understanding about the operation of three of the company's nuclear reactors beyond 40 years. R&I will pay attention to whether Kansai Electric Power can restore trust by developing a sound corporate culture, with the overhaul of its management team and the transition to a company with a nominating committee, etc. acting as a stepping stone.

The Chugoku Electric Power Co., Inc. The Chugoku Electric Power Co., Inc. has seen a relatively low rate of customer loss to PPSs in the industry, because it has not raised electricity rates since the occurrence of the Great East Japan Earthquake. Meanwhile, management faces a challenge of rebuilding the company's revenue/expenditure and financial position. In response to a severe business environment caused by the prolonged suspension of nuclear plant operation, the company has shifted to conservative financial management in recent years by optimizing electricity rates and selecting investment targets carefully, for example. The conversion of some convertible bonds into shares is also a positive factor. Based on its view that a rating downgrade has become less likely, R&I has changed the Rating Outlook to Stable. Chugoku Electric Power is comparatively highly dependent on inefficient coal-fired power, including that from Electric Power Development Co., Ltd., and a decrease in power supply from such sources must be offset by electricity from Unit 2 of the Misumi Power Station, which is under construction, and nuclear power from reactors that may resume operation. A future impact warrants attention, though the government's stance on ensuring stably power supply and some progress made in the conformity evaluation of Unit 2 of the Shimane Nuclear Power Station are positive factors.

Hokuriku Electric Power Co. Hokuriku Electric Power Co. raised electricity rates for customers excluding regulated sectors such as some residential customers in April 2018, and this led to a surge in customers switching to other suppliers. Even so, the company achieved a certain increase in revenue. Its coal-fired power source was forced into an emergency shutdown due to facility trouble in FY2018 and FY2019, but went back into full operation in July 2020, which is expected to help improve its revenue/expenditure. In the conformity evaluation of Unit 2 of the Shika Nuclear Power Station, a reactor saddled with the issue of a fault on the premises, a path to denying the activity of the fault is emerging following the July 2020 evaluation meeting. Based on its view that downward pressure on the rating has been almost eliminated, R&I has changed the Rating Outlook to Stable. Hokuriku Electric Power has certain supply capacity from inefficient coal-fired power sources, but there are no ongoing plans to construct new or additional thermal power sources. Although the company has some extra supply capacity thanks to an LNG-fired power plant that started operation in FY2018, R&I will keep an eye on the government's detailed measures, the company's responses, and their impact on earnings including those from wholesale.

Tohoku Electric Power Co., Inc. Since its electricity rate hikes in 2013, Tohoku Electric Power Co., Inc. has maintained a relatively stable revenue/expenditure structure, though its nuclear reactors have been out of operation. The stability of the rating has increased thanks to this, along with improvement in the debt-equity structure, which was undermined by damage from the Great East Japan Earthquake. While competition with the TEPCO Group is intense, its electricity sales in the Greater Tokyo area are solid. In February 2020, Unit 2 of the Onagawa Nuclear Power Station passed conformity evaluation, making a step toward resumption of operation. The company aims to complete construction works for safety measures in FY2022. As regards the conformity evaluation of the Higashidori Nuclear Power Station, some progress has been made in the assessment of the activity of a fault on the premises. Its inefficient coal-fired power sources, including jointly funded plants, have substantial supply capacity. Tohoku Electric Power has a certain capacity to deal with suspension or closure of such sources, with construction of new or additional thermal power sources underway. Even so, R&I will examine the government's detailed

measures to reduce inefficient coal-fired power sources and their impact on the company's earnings base.

Shikoku Electric Power Co., Inc. Shikoku Electric Power Co., Inc. has a revenue/expenditure structure where the capacity utilization of Unit 3 of the Ikata Nuclear Power Station, the only nuclear reactor of the company, affects fuel costs and sales volumes significantly. Ikata Unit 3 has been taken off-line in response to the High Court's second temporary injunction to halt operation in January 2020. The company will seek withdrawal of the temporary injunction by filing an objection, but it is difficult to predict when the reactor will restart. Because of this, combined with an anticipated failure to meet the March 2021 deadline for installing SSFs, the nuclear capacity factor will likely remain low for some time. Although the company has certain financial resilience, attention should be paid to the possibility that the reactor will be out of operation for an unexpectedly long period of time. The supply capacity from inefficient coal-fired power sources include electricity supply from Electric Power Development and in-house power generation facilities in Shikoku Electric Power's service area, in addition to its own power sources. While the company has relatively large extra supply capacity and is expected to benefit from facilities replacement at its Saijo Thermal Power Station, R&I needs to examine the government's detailed measures and their actual impact on the company.

Kyushu Electric Power Co., Inc. Kyushu Electric Power Co., Inc. achieved the nuclear capacity factor that is assumed for its electricity rate costs, with its four nuclear reactors resuming operation by FY2018. Meanwhile, its financial profile requires significant improvement. Due primarily to low market prices of wholesale electricity and losses from LNG resale, the company recorded a net loss in FY2019, which has slowed financial improvement after the restart of the reactors. In FY2020, a delay in the completion of installing SSFs has dampened the capacity utilization of Units 1 and 2 of the Nuclear Power Station, but a high-efficiency coal-fired power source that started operation in FY2019 will contribute to full-year results. Kyushu Electric Power faces a challenge of securing a sufficient nuclear capacity factor by swiftly completing the installation of SSFs for Units 3 and 4 of the Genkai Nuclear Power Station as well. The company has certain supply capacity from inefficient coal-fired power sources, including electricity from Electric Power Development. Eyes will be on the government's measures to reduce such power sources and their impact on the company's revenue/expenditure.

Hokkaido Electric Power Co., Inc. Hokkaido Electric Power Co., Inc. has continued to post ordinary profit since FY2015 thanks to two electricity rate hikes, though the conformity evaluation of Unit 3 of the Tomari Nuclear Power Plant has been protracted owing to a fault on the premises. In response to a substantial loss of customers resulting from relatively high electricity rates, the company has strived to restore customers in recent years by strengthening competitiveness using savings from management efficiency enhancement. With the withdrawal of a PPS acting as a tailwind, Hokkaido Electric Power regained its market share in the high voltage and extra high voltage sector and increased its electricity sales volume in FY2019 for the first time in nine years. Its power mix has been diversified by the commencement of operation of an LNG-fired power source in FY2019. Moreover, profit accumulation and a subordinated loan have partly offset the deterioration in the financial base caused by the Great East Japan Earthquake. Based on its view that downward pressure on the rating has diminished, R&I has changed the Rating Outlook to Stable. The company's main baseload power sources will be inefficient coal-fired power as long as its nuclear reactors are off-line. Since an early reduction in such inefficient power sources could heighten the risk of supply-demand imbalances, the government's detailed measures will most likely give due consideration to local circumstances.

NEWS RELEASE

Electric Power Development Co., Ltd. Electric Power Development Co., Ltd. is engaged in the power generation and transmission businesses. Its power sources as a whole are very cost competitive, because the power mix is centered on thermal power sources, primarily coal-fired power, and also includes large-scale hydroelectric power plants. Moreover, the overseas business generates solid earnings thanks to an increase in power generation capacity. The company is constructing a nuclear power plant in the town of Ohma on the Shimokita Peninsula of Aomori Prefecture. For the plant, a sizable cost is recorded in the construction in progress account, and a delay in recouping the investments constrains the company's creditworthiness. As regards its main coal-fired power sources, developments in carbon dioxide emission regulations warrant attention. Inefficient facilities, which account for around 40% of its coal-fired power generation capacity, have a low book value because of the progress of depreciation. That said, reducing these facilities would weaken the company's earning capacity. While the remaining domestic power sources and the overseas business are expected to allow Electric Power Development to maintain a certain level of profits, R&I will closely observe the government's detailed measures and their impact on the company.

The Japan Atomic Power Co. The Japan Atomic Power Co.'s Tokai No.2 Power Station passed conformity evaluation, and the company obtained approval for the construction plan and extension of operation of the plant. It will also be able to raise funds to conduct construction works for safety measures, as Tokyo Electric Power Co. Holdings, Inc. and Tohoku Electric Power expressed their intentions to provide financial support. The construction works are underway, with completion scheduled for December 2022. Furthermore, the company secured funds for bond redemption in FY2020 by, for example, selling part of its shareholdings in Japan Nuclear Fuel Ltd. Near-term liquidity has been ensured, and continued strong support can be expected from customer power companies. Based on its view that downward pressure on the rating has diminished, R&I has changed the Rating Outlook to Stable. Eyes are on the progress of the conformity evaluation for Unit 2 of the Tsuruga Nuclear Power Station, which faces the issue of a fault on the premises, as well as on developments in efforts to gain understanding from local residents about the Tokai No.2 plant.
