EGC discusses rising labor costs and prices under revenue cap system

(Government statement, October 22)

  • Electricity and Gas Market Surveillance Commission (EGC) experts discussed how to handle rising labor costs and prices under the revenue cap system.
  • To reflect labor cost and price increases from the first regulatory period of the revenue cap system (FY2023-2027) in wheeling charges, the applicable period is considered as two years starting FY2026.
  • Since revising ordinances and investment plans takes time, adjustments are mainly planned for the second regulatory period (FY2028-2032).
  • Operators interested in mid-term adjustments during the first period may apply.
  • CONTEXT: This system sets a maximum revenue for power grid operators, ensuring fair consumer prices while promoting efficiency and investment. However, there are cases where increases in labor costs or fuel prices cannot be fully passed on to the consumer via rates; thus, rising costs may place an excessive burden on the operators.
  • TAKEAWAY: Stable power supply requires maintaining supply chains and construction capacity, reinforcing networks for decarbonization and data centers, and enhancing resilience. TSOs’ efficiency efforts alone cannot offset rising costs, so appropriate regulatory measures, including for the first period, are now needed.

EEX and TOCOM host Japan Power Summit

(Company statement, Japan NRG, October 21)

  • The European Energy Exchange (EEX) and Tokyo Commodity Exchange (TOCOM) hosted “Japan Power Summit 2025” to discuss electricity futures trading.
  • There were more than 800 participants, including trading professionals and experts from major electric power and gas companies in Japan and abroad.
  • Chugoku Electric and RWE Supply & Trading Japan gave keynote speeches.
  • In panel discussions, traders and risk managers shared experiences, and the challenges and potential of Japan’s rapidly growing electricity futures market.
    • The govt’s proposed Mid-to-Long-Term Power Market reform came under especially heavy scrutiny, with domestic power company representatives questioning the need for such a system on top of the existing futures markets.
    • Most speakers said they expect continued growth in the derivatives market and volumes to increase several fold in the next few years, though they also warned bourse operators not to expand the product range too quickly fearing that it would fragment liquidity.
    • Both the EEX and TOCOM confirmed plans to roll out Chubu area products in the coming months, adding to the Tokyo and Kansai area derivatives.
    • Once the market volumes expand, there may be room to add also the Kyushu area futures and options, according to some traders.
  • CONTEXT: Japan Power Summit launched in 2023. Interest in it has grown since electricity futures began trading on TOCOM in 2019 and on EEX in 2020.
  • TAKEAWAY: The bi-annual gathering of power market participants has grown not only in terms of the number of firms participating but also the scope of those joining. From electricity traders to BESS developers and solar plant operators, the event has been able to pool a large slice of the broader electricity industry. This also shows how power generators are becoming more interested in markets and market-based pricing mechanisms, envisioning a future in which even wind and solar farms, batteries, and other power facilities are selling a portion of their output directly into the markets.

NEWS: SOLAR AND BATTERIES

Infrastructure funds investing in large-scale PV farms face financial struggles

(Nikkei, October 24)

  • Japan’s listed infrastructure funds, mainly investing in large-scale solar power plants, struggle financially. Their combined market capitalization has dropped 35% in two years to ¥106.4 billion.
  • Declines are driven by output curtailments, equipment theft, and rising maintenance and financing costs amid inflation and higher interest rates.
  • For instance, Canadian Solar Infrastructure Fund lost about 14% of revenue from curtailed generation in early 2025, while Japan Infrastructure Fund Investment Corp saw losses of around 5% annually.
  • Theft of copper cables has caused shutdowns and dividend cuts. For instance, Tokyo Infrastructure & Energy Investment cut per-unit dividends by 40% to ¥1,693.
  • To offset risks, funds are adding storage batteries and shifting from the FIT to the FIP, which allows market-based sales with subsidies and reduced curtailment priority.
  • Some funds, such as Japan Infrastructure Fund, plan to convert all Kyushu sites to FIP by FY2026, while others are exploring direct power sales agreements post-FIT.
  • CONTEXT: Investors remain cautious due to the expiration of 20-year FIT income (starting 2032) and the lack of clear post-FIT growth strategies.
  • The industry association stresses that renewed investment flows are crucial for expanding renewables and achieving national decarbonization goals.

NEWS: WIND POWER AND OTHER RENEWABLES

JERA Nex bp cancels Beacon Wind project, exits U.S. offshore market

(Japan NRG, October 22)

  • JERA Nex bp, the offshore wind venture between JERA and bp, is drastically cutting operations in the U.S., cancelling projects such as Beacon Wind off Massachusetts (up to 2.5 GW). The project would have fed the New York grid.
  • The firm cites reduced state subsidies and rising costs as reasons for the decision.
  • Although environmental reviews were completed while Biden was still in the White House, final permits were never issued.
  • JERA Nex bp will retain U.S. lease rights but its entire local team will leave; the firm will focus on Europe and Japan.
  • CONTEXT: The company holds the rights to 13 GW of as-of-yet uncompleted offshore wind projects, primarily in Europe.
  • TAKEAWAY: Policy hurdles under Trump, including permitting delays and subsidy cuts, have created a challenging environment that continues to influence development decisions and has led many companies to cancel plans despite investment losses. Combined with rising costs, this has made U.S. wind projects unviable. JERA has only recently created the tie-up with bp in the wind sector and it has taken on a huge challenge given the sector’s condition today. Still, it’s a bet on offshore wind power becoming a significant part of the future clean energy mix and while buildout in the U.S. is currently off the table, the sector’s fortunes in Europe are good and set to improve in Japan too.

TEPCO begins removing fuel from Kashiwazaki-Kariwa NPP Unit 7

(Denki Shimbun, October 22)

  • TEPCO began removing nuclear fuel from Unit 7 at Kashiwazaki-Kariwa NPP. The fuel was loaded in April last year, but the reactor remains idle because the required special safety facilities aren’t ready yet.
  • Instead of storing fuel inside both the reactor and in the spent fuel pool, all of it will be consolidated in the pool. This will make management easier.
  • SIDE DEVELOPMENT:
  • Niigata Pref to survey public opinion again on Kashiwazaki-Kariwa restart
  • (Nikkei, October 24)
    • Niigata Pref will hold another public opinion survey on Kashiwazaki-Kariwa NPP’s restart, from Oct 24 to Nov 7, targeting 8,344 residents within a 30-km radius.
    • Governor Hanazumi will use the results to make his decision on the NPP’s restart.
    • CONTEXT: The survey comes after an earlier one showed that only 37% agreed that the NPP meets conditions for restart. 60% disagreed. As the Governor wants to use the results to reach his own decision, this further delays the restart.
  • TAKEAWAY: As Japan NRG has said multiple times, Governor Hanazumi is stalling for time and is unlikely to make any decision before 2026, when he is likely to use his re-election campaign to test the water on local appetite for a restart. Given the lack of a formal structure in the local approval process for a nuclear reactor restart, Hanazumi is free to conduct his decision-making as he wishes.

  • Treasury Sec Bessent called on allies to join and enforce these sanctions.
  • Japan continues to import LNG from Russia’s Far East under an existing exemption, and plans to request an extension for them from the U.S.
  • CONTEXT: Rosneft participates in Sakhalin-1, an oil and gas project in Russia’s Far East. Japanese investors include METI, JAPEX, Itochu, and Marubeni.
  • From Japan’s point of view, the main concern lies with Sakhalin-2, a project that is largely producing LNG. The ownership is as follows: Gazprom (77.5%), Mitsui (12.5%), and Mitsubishi (10%).
  • Gazprom and its affiliated banks are under U.S. sanctions. But, Sakhalin-2 remains exempt, allowing Japan to continue LNG imports from it and a tiny amount of oil. Russian LNG accounts for about 9% of Japan’s total imports, supplying both power utilities and gas companies.
  • The U.S. had previously extended the Sakhalin-2 transaction license until Dec 19. METI is lobbying for a further extension.
  • TAKEAWAY: Following Japan’s 2022 oil import ban on Russia, Sakhalin-1 already ceased shipping crude oil to Japan. Officials in Tokyo say the new U.S. sanctions have little immediate impact on fuel supplies. METI maintains that Japan’s stakes in the Sakhalin projects are important for energy security, and experts warn that if Japan’s LNG imports from Russia stop, domestic electricity and gas prices could rise.
  • SIDE DEVELOPMENT:
  • METI Minister comments on U.S. pressure over Russian energy imports
  • (Nikkei, October 21)
    • METI’s Minister Muto said Russian LNG plays an “important role” for Japan’s energy security. He expressed caution about stopping imports.
    • He said rising procurement costs in the tight Asian market could lead to higher electricity prices.

Japan’s New Cabinet Blends Industrial Pragmatism With Defense Innovation

The new prime minister, Takaichi Sanae, has assembled a cabinet that signals continuity in Japan’s energy realism, but with a sharper industrial edge. One of her first promises, to cut the gasoline tax, underlines that pragmatism: easing household and transport costs while signalling that energy affordability, not only decarbonization, will define her agenda.

Takaichi has often been described as a political firebrand, but her Cabinet picks indicate a careful balance between trade, business, and politics. Her choice of Akazawa Ryosei as METI minister and Koizumi Shinjiro as defense minister suggests that she intends to link energy security, technological innovation and national resilience more tightly than before. Heading the MoE is former banker Ishihara Hirotaka – a nod to how environment policy is increasingly linked to investment, green finance and international capital flows.

Akazawa’s role will be in part to progress the major energy and other infrastructure projects that he agreed with the U.S. in his role as chief trade negotiator under the prior administration. Koizumi’s presence should see a more concerted effort to integrate renewable energy into key national defense and other facilities, opening further opportunities for clean tech that also gets dubbed as ‘dual use’ for its military application.

Meanwhile, the appointment of several veteran METI officials at Takaichi’s office should help to advance the national strategy of coordinating industrial, digital, and energy developments. From the Watt-Bit Collaboration to the GX Hubs initiative, the government – and METI in particular – has embarked on a mission to sync the expansion of new industrial facilities with clean energy resources, using this as a driver to meet the nation’s 2050 carbon neutrality goal.

METI: keeping promises

Akazawa, a 64-year-old former transport bureaucrat turned politician, is a quintessential policy insider. A graduate of the University of Tokyo and Cornell University, he has served in roles ranging from transport policy to economic revitalisation. He arrives at METI with a reputation for competence, not flash, and strong loyalty to outgoing PM Ishiba.

His appointment extends rather than overturns Japan’s long-standing approach to energy: pragmatic, security-minded and increasingly cost-conscious. Yet Akazawa’s instincts point to a subtler recalibration. In line with Takaichi’s orders, he appears keen to place industrial strength at the heart of decarbonization, an approach that favors domestic manufacturing, supply-chain stability and international trade links as much as climate goals.

Japan’s strategy for hydrogen and ammonia, for example, is likely to be framed less as a climate virtue and more as a strategic industrial opportunity to support GX in sectors ranging from steel to shipping.

At METI, Akazawa inherits a familiar set of dilemmas. Nuclear restarts remain slow, but the economic logic for reviving reactors has grown. A weak yen has made fossil-fuel imports – particularly LNG – expensive, even if Japan’s long-term contracts strategy offers some respite. Renewables deployment continues, but with rising costs and local resistance to large-scale projects. The offshore wind sector is in a particularly sensitive spot.

Akazawa’s team is expected to stress incremental renewables expansion and squeeze more from existing mechanisms rather than roll out new initiatives. Expect to see more ‘overloading’ of existing auctions, such as the LTDA, to cater to all sectors.

Akazawa will also oversee Japan’s growing web of energy and industrial investments in the U.S. At the upcoming Oct 28 Takaichi–Trump summit, Tokyo plans to tout a series of commitments to U.S. energy, semiconductors and materials. The giant Alaska LNG complex, and the Stargate AI infrastructure with accompanying data centers, sit squarely within a $550 billion investment and trade framework that Akazawa agreed to with the White House in September, and which also covers critical minerals and shipbuilding.

In short, Akazawa represents not a break from past realism but its evolution into a more industrial-centred pragmatism – one that measures energy not only in carbon or cost, but in terms of competitiveness and geopolitical return.

In defense of renewables

If Akazawa’s METI embodies industrial pragmatism, the appointment of Koizumi at the defense ministry hints at an institutional broadening of the domestic energy debate. A protégé of former defense minister Taro Kono, a long-time advocate of renewables and transparency, Koizumi is expected to encourage the Self-defense Forces (SDF) to take energy resilience more seriously.

The military establishment has traditionally left such matters to METI. Yet as U.S. strategists have learned, energy security is no longer peripheral to defense planning. America’s armed forces have spent two decades hardening bases against floods, typhoons and thawing permafrost – a practical response to climate stress rather than a political statement. Even as Washington’s civilian leadership drifts in and out of climate rhetoric, the Pentagon continues to integrate renewable power, micro-grids and fuel diversification into its operations.

Tokyo has been keeping tabs. The creation in 2024 of the Defense Innovation Science & Technology Institute (DISTI) – modelled on DARPA in the U.S. – gives Koizumi a tool to pursue that integration. With a budget of around $140 million and a staff of a hundred researchers, DISTI’s remit spans AI, robotics and energy systems for defense.

The project’s launch marked Japan’s recognition that defense innovation must cover not only weapons but the power systems that sustain them. Expect at least some of the increased defense budget to end up in items that would historically have been labeled as energy.

Koizumi may push his ministry to see renewables as not only an environmental tool but a bet on distributed generation to keep communications and logistics running, should the grid ever get attacked or disabled. The compactness of SMRs may also appeal. Koizumi’s recent mention of Japan’s interest in nuclear submarines is not a random talking point.

In August, the U.S. Council on Strategic Risks argued that Japan’s security could be strengthened further through closer coordination between renewables policy and defense planning, underpinned by better access to critical minerals. They even suggested reducing METI’s dominance of the energy portfolio and fostering “energy literacy” across the diplomatic and security establishment.

That is, of course, easier said than done. The bureaucratic borders in central Tokyo are among the most entrenched in the world. Still, the proposal captures the blurring of the lines between energy, security, industrial policy and national resilience. Expect this trend also to open more opportunities for clean/ deeptech startups working on ‘dual use’ technologies, such as drones, which can deliver energy efficiencies as well as a military edge.

Cross-government approach?

For now, cooperation between METI and the defense Ministry is more a concept than a program. Each guards its turf. Yet as their interests converge, people like Takaichi’s principal executive secretary Iida Yuji will become increasingly influential. Iida was until recently METI’s top bureaucrat; he will now act as the prime minister’s key coordinator across ministries.

A career official steeped in energy policy, Iida spent much of his tenure at ANRE and later led METI’s Economic and Industrial Policy Bureau, where he oversaw the nexus of energy, environment and industry.

Also, keep an eye on the new environment minister. Son of late Tokyo governor Ishihara Shintaro, he is a six-term lawmaker and former State Minister of the Environment.

Before entering politics he worked for the Industrial Bank of Japan and Mizuho. That experience should prove valuable as Japan tries to fuse environmental policy with industrial and financial priorities – and raise up to ¥20 trillion in a bond program linked to the GX investment plan.

Ishihara has long argued that growth and decarbonization can reinforce one another, not compete – a stance that aligns neatly with PM Takaichi’s push for pragmatic, investment-driven climate policy. His appointment signals that the MoE will be expected to speak the language of markets (and especially carbon markets) as well as that of regulation.

In areas like hydrogen and batteries the various ministries could find much common ground, especially as these technologies rely on secure access to critical minerals, which means finding alternatives to supply chains dominated by China.

A pragmatic symbiosis

Takaichi’s cabinet is not seeking an energy revolution; it is refining Japan’s established forms. That may feel uninspiring. Yet in an era of wild policy swings elsewhere, Japan’s incrementalism is a kind of virtue: stability disguised as stasis.

For investors and industry, this means a steady policy environment. Nuclear restarts will inch forward; hydrogen and ammonia will remain subsidized but scrutinized; renewables will expand but face higher local-content expectations. Defense-related R&D could open new commercial avenues in storage, mobility fuels and critical-materials processing.

Japan has long been pragmatic about energy. That pragmatism’s center of gravity is changing: from fuel import security toward an integrated model that ties energy, resilience, industry and defense all together.

KEPCO To Shut Last Oil-Fuelled Units, but Nuclear and LNG on the Rise

At the end of September, Kansai Electric (KEPCO) announced plans to shut units at the oil-fired Gobo Power Station in Wakayama Prefecture, accelerating the utility’s pivot away from carbon-intensive generation.

Gobo has long functioned as a strategic reserve facility, but declining use rates and rising maintenance challenges have made its role marginal. While Units 1-2 will be decommissioned, the fate of Unit 3 remains undecided.

KEPCO is not alone in this shift. A growing number of Japanese utilities are retiring their thermal fleets with over 25 GW of oil-, gas- and coal-fired slated for decommissioning this decade. But only KEPCO can count on a sizable operational nuclear power plant fleet. Indeed, its energy mix leans more and more on nuclear power, in the wake of NPP restarts.

Japan NRG takes a closer look at KEPCO’s shift – what’s behind it, and most importantly what comes next.

Goodbye to Gobo

Located in Wakayama Prefecture, Gobo Power Station was commissioned in phases from 1984 and 1985. The three generating units, each 600 MW, have a combined output capacity of 1.8 GW, roughly 18% of KEPCO’s total fossil-fuel power.

Unit 2 has been offline since 2019, with the other units serving as backup to meet spikes in demand or to compensate for dips in renewable output. The relative ease of oil storage has made it useful for such emergency roles. Still, at present, Gobo Unit 1’s capacity utilization rate is reported to be at only 4%.

This fall, the utility decided that Units 1 will retire by June 2026, while Unit 2 will retire by the end of this month. KEPCO told Japan NRG that maintenance of such facilities is difficult, due to multiple factors such as advanced age, as well as changes in operating status.

As for Unit 3, the utility said no decision has been made. Options include the possible use of it as a reserve power system. KEPCO plans to monitor trends in the balance of power supply and demand, as well as national energy policies. If it’s assessed to be surplus to requirements, it could be suspended or decommissioned.

Gobo’s fate follows KEPCO plans to decommission two units (600 MW each) at the oilfired Ako Power Station, in Hyogo Prefecture. Launched in 1987, it was fueled by crude oil and heavy fuel; operations ended in July. Another oil-based KEPCO facility, the Tanagawa Daini Power Plant, which also consisted of two 600 MW units, was retired in 2020, about 43 years after it launched.

A third KEPCO oil-fired facility was Aioi, with three units. In 2022, Units 1 and 3 were shut. Unit 2 is still operational, though converted to run on solid biomass and with its capacity reduced from the original 375 MW to 200 MW.

Other utilities follow

KEPCO’s decision comes at a time when other utilities are taking similar steps. By March 2026, Kyushu Electric plans to decommission Unit 2 of Buzen Power Station, which will end all its oil-fired power generation.

By 2030, J-Power will also retire or suspend five coal-fired units. JERA, the country’s largest power generator, aims to end utilization of inefficient coal plants by 2030. Hirono Unit 2 in Fukushima was JERA’s last oil-fired plant in the Tokyo area.

In early October, JERA decommissioned old LNG plants, namely Anegasaki Units 5 and 6; Sodegaura Unit 1, Chita Unit 5; and Hirono Unit 2. Their total capacity is 3.2 GW, and were idle for years, too degraded to restart. Since FY2020, the utility has added or replaced 7.3 GW of power generation capacity.

JERA is now building Chita Units 7 & 8 (1.3 GW, LNG fuelled, slated to launch in FY2029). Plans also include new Sodegaura Units 1–3 (about 2.6 GW) launching in 2032, with environmental reviews underway.

LNG and BESS on the rise

In FY2014, fossil fuels accounted for almost 90% of KEPCO’s total generation, following the shut downs of nuclear generation after the 2011 Fukushima disaster. Oil accounted for about 15% of that fossil-fired total.

Source: KEPCO

Since then, nuclear has made major strides. In FY2019 fossil fuels accounted for 59% of KEPCO’s power generation, and nuclear for 27%. By 2023, KEPCO had restarted all seven of its operable nuclear reactors, and fossil fuel power now accounts for 39% (with oil covering less than 1% of that), while nuclear rose to 48%. All these years, hydropower has remained stable at about 10% of the total.

While nuclear power has rebounded, KEPCO told Japan NRG that LNG-fired generation is also seen as a rising star – a flexible and necessary transitional option, an effective response to rising power demand from data centers.

Among KEPCO’s LNG-fuelled facilities, there are the 1.8 GW Nanko station (three units), the 1.5 GW Himeji No. 1 (four units), and the 2.9 GW Himeji No. 2 station (six units). These are slated for upgrades and modernization in the early 2030s. The Sakaiko Power Station, five units, is also a 2 GW LNG-fired facility.

For balance in the fuel portfolio, KEPCO has the 1.8 GW coal-fired Maizuru station (two units) and the Kansai International Airport Energy Center (40 MW), fuelled by LNG and kerosene.

One area where KEPCO feels it needs to strengthen its power supply assets, however, is energy storage. Batteries would offer flexibility in balancing the generation assets and the rising renewables volumes locally. Toward that goal, the Kansai utility plans BESS facilities in the Kanto and Chubu regions, targeting an energy storage capacity of 1 GW by the early 2030s. There are plans for massive 100 MW-class BESS facilities also in Sapporo, Osaka, Hamamatsu, and Mito.

So far, KEPCO has set up the Kinokawa Battery Station, together with Orix, which has a rated output of 48 MW and capacity of 113 MWh, making it one of Japan’s largest.

Conclusion

Oil-fired power’s economic viability is dwindling, squeezed by two imperatives – energy security and decarbonisation. KEPCO’s generation mix is a case study of the new calculus for legacy power assets that are caught between volatile fossil fuel prices and climate policy.

In short, the advanced age and high maintenance costs of the Gobo units are no longer tenable.

With half of its electricity sourced from nuclear power, KEPCO has also been more appealing to new corporate electricity clients seeking CO2-free energy. Nuclear power now provides the base load in KEPCO’s new mix, as restarts have restored balance to the grid.

Still, following KEPCO’s path is hardly an option for other utilities. Many still struggle to restart their NPPs. Hence, the Kansai utility’s views on natural gas reflect how its large LNG-fired fleet remains crucial. The super-chilled fuel is seen as the most flexible and viable transitional option for now to meet quickly rising energy demand.

In the future, options outside natural gas may emerge. KEPCO’s investments in battery storage and a dogged pursuit of hydrogen and CCS signal interest in those directions.

With some large industrial customers of TEPCO’s retail units grumbling about losing discounts, KEPCO has a good chance of expanding its client base thanks to its diversified mix. And, as the carbon credits market in Japan moves to the mandatory phase, this will be a powerful sales pitch to secure major new corporate revenue.
