NEWS: GENERAL POLICY AND TRENDS

ANRE, OCCTO list issues to tackle to build simultaneous market system 

(Government statement, March 24)

  • ANRE and OCCTO experts discussed issues for creating a simultaneous market:
    • For the seller side, the issues are: How to bid with self-scheduled power sources (where the plant operator determines the start of the power source by themselves); What mechanism to use when self-scheduled power source bids are restricted; How to register operating parameters; How to bid for power sources other than thermal power; and, How to operate power sources that require one week (or, at least more than one day) to bring online.
    • For the buyer side, the issues are: The bid process; and bidding obligation for demand that’s linked to bilateral contracts.
    • In terms of power supply security, the issue is how to respond in the event that demand differs from TSO expectations. 
    • Regarding methods for calculating market prices: There are questions around the price per kWh in a situation when there is grid congestion; how to determine the price per Δ (delta) kW; and How to set individual compensation for power generation costs (uplift). 
    • In terms of the intraday part of the simultaneous market, the issues are timing and frequency of holding the market, the settlement target, and how to change bidding content.
    • For actual supply-demand, the debates are around how to set the price of balancing power per kWh and the imbalance charge. 
  • To introduce a simultaneous market, the roles of the operating entities will need to be clarified, and a system will need to be established to ensure that they work together.
  • Next, the govt study group intends to confirm the current operations and management of JEPX, EPRX and OCCTO, paying particular attention to functions and operations utilized in market management, as well as mechanisms used for information exchange with related organizations.

TAKEAWAY: The Study Group on the Simultaneous Market is charged with finding a way to introduce such a market in Japan. The group has met 12 times since February 2023, and it published an interim report on initial findings in November 2024. For a detailed look at the Simultaneous Market discussions and implications, please see this week’s Analysis section.

Govt launches meeting on Watt-Bit Coordination

(Government statement, March 21)

  • The Ministry of Internal Affairs and Communication (MIC) and METI launched a new body, known as the Public-Private Meeting on Watt-Bit Coordination. It brings together members of the power, telecom and data center (DC) industries.
  • The govt wants to accelerate the digital transformation (DX) in the country through the rollout of AI, and promote coordination between the electricity and telecom sectors (the Watt-Bit Coordination) with upgraded infrastructure in order to achieve growth, decarbonization and national resilience.
  • Working groups will be held and a summary will be produced in June after four monthly meetings for technical and practical discussions.
  • CONTEXT: MIC and METI held “Expert Meetings on Development of Digital Infrastructure (DC, etc.)”, and published an interim report on findings in October 2024. It indicated the need for urgent measures to develop digital infrastructure. The GX2040 Vision, approved by the Cabinet in February, underscored the importance of effective coordination between electricity and telecoms to build infrastructure to achieve rapid development of data centers, which require lots of electricity.

TAKEAWAY: As ordered by PM Ishiba to both ministers at the Digital Government and Finance Reform Council on Feb 20, there is a government push to integrate the development of power and telecom infrastructure. The urgency can be seen from how quickly this initiative is moving. From a first meeting in March, the group is expected to deliver a detailed roadmap for future efforts within three months. This suggests there is already a consensus about which direction policy needs to move in to facilitate inter-sector collaboration. 

ANRE resumes discussions of measures to promote biodiesel

(Government statement, March 25)

  • ANRE listed key issues for introducing biodiesel, and proposed measures.
  • Japan’s maximum blending ratio of Fatty Acid Methyl Ester (FAME) in diesel to create biodiesel for trucks, buses and other vehicles is currently 5% (B5). This will be increased to the same level as in Europe, 7% (B7).
  • The fuel for construction machinery, etc, is also limited to B5, but following the examples of Europe and the U.S., a new JIS standard for B20 and B30 fuel exclusively for off-road use will be formulated so that it can be introduced in Japan.
  • Modern-day biodiesel with HVO (Hydrotreated Vegetable Oil) has the same chemical formula as diesel fuel, but Japan has not as yet established a standard for its handling. 
  • Since HVO has a lower density than existing fossil-based diesel, it does not fall under the definition of ‘diesel’ for the purposes of diesel tax. So, regulations and operation of the tax on diesel will be reviewed.
  • CONTEXT: There is growing momentum towards using biodiesel for construction machinery and as a marine fuel to cut emissions. In addition to demos of high blends of biodiesel, the govt is also promoting biodiesel as part of national policy. The 7th Basic Energy Plan states that biodiesel should be prioritized in transportation. However, issues such as standards and taxation have hindered its spread so far.

TAKEAWAY: As when blending bioethanol with gasoline, discussions about blending biodiesel with diesel began about 20 years ago. It has yet to become widespread due to cost, supply volumes, and product standards. In the past few years, the government has put more priority on supporting hydrogen and ammonia as low carbon fuels, but recent moves show that biofuels are back in favor. 

Japan asset managers start to exit financial net-zero alliance

(Nikkei Asia, March 27)

  • Tokio Marine Asset Management left the Net Zero Asset Managers initiative formed by leading financial industry players to tackle climate change. 
  • CONTEXT: This exit begins the outward trickle of Japanese asset management companies, following banks and insurance companies. Most U.S. banks and insurers have also quit NZAM. The world’s largest asset manager, Blackrock, left in January.

TAKEAWAY: These exits were on the cards as soon as Trump called for the U.S. to withdraw from the Paris Agreement, again. Most financial companies that have left NZAM plan to continue with climate and sustainability policies independently. NZAM’s implosion creates an opportunity for new frameworks to emerge, possibly centered on Europe.

 

NEWS: ELECTRICITY MARKETS

JERA acquires EDF Trading’s Tokyo desk to expand in Japan’s power trading

(Company statement, March 27)

  • EDF Trading and JERA Global Markets will merge operations in Japanese power trading. JERA GM will effectively take over the Tokyo desk of EDF Trading.
  • CONTEXT: EDF Trading has built up one of the biggest power trading desks in Japan. JERA GM is a JV between JERA (two-thirds owner) and EDF Trading (the rest), and focuses on trading in fuels.
  • The two companies launched cooperation in 2008, when EDF Trading was a counterparty with Chubu Electric on coal procurement. (JERA is a 50-50 JV between Chubu Electric and TEPCO).
  • The integration of the two trading desks takes effect from April 1, 2025. JERA GM will continue to operate out of the Coredo Nihonbashi building in Tokyo with an expanded team of over 50 staff.

TAKEAWAY: JERA is the world’s largest LNG importer, but in the last couple of years it has also tried to expand into international gas trading that’s not directly linked with the fuel needs of its power plants. JERA has a Singapore office to bolster its global LNG trading while also dipping its toes into the electricity markets at home. The addition of EDF Trading expands JERA’s resources considerably and should help make it a top player in Japan’s fast-growing power derivatives markets.

JERA seeks to supply gas-fired power for data centers

(Nikkei Business, March 27)

  • JERA plans to enter the data center market by constructing gas-fired power plants near data centers, or by attracting data centers next to its existing facilities, providing rapid and stable electricity supply through on-site PPAs.
  • CONTEXT: Rising demand from IT firms competing in generative AI development has accelerated the expansion of data centers. However, the volume of renewable energy in development lags behind, pushing operators to explore other ways to secure electricity. This is where generators of gas-fired power plants hope to come in, knowing that the availability of electricity from nuclear plants in Japan is limited.
  • Gas-fired generation supplies 35% of Japan’s electricity, with JERA responsible for roughly 30% of the nation’s total generation. JERA operates gas-fired plants at 26 locations, mostly around urban areas.

TAKEAWAY: The lack of available power for new data centers is starting to push U.S. operators to review other options. Just a few months ago, ExxonMobil said it will design large (1.5 GW or more) gas-fired power plants specifically to serve data centers in the U.S. JERA seems to be the first Japanese company to test interest for similar applications here.

  • SIDE DEVELOPMENT:
  • NYK to begin experiment in Yokohama for offshore data center 
  • (Company statement, March 27)
    • NYK will begin an experiment in Yokohama in autumn to develop an offshore data center powered by renewable energy. A test facility will operate on stored battery power, examining potential issues such as salt damage. 
    • CONTEXT: NYK, Mitsubishi UFJ Bank, NTT Facilities, Eurus Energy Holdings, and Yokohama City are partners on the project that calls for a container-type data center with solar panels and batteries on a floating mooring facility. 

TAKEAWAY: Nuclear power is often regarded as the most reliable energy source for meeting the growing energy demands of data centers, especially given many operators’ preference for non-fossil fuel sources. However, exploring alternatives, particularly battery storage, could offer a viable solution.

Editorial: TEPCO must rewrite path to reconstruction

(Nikkei, March 23)

  • CONTEXT: This is an editorial from Nikkei.
  • TEPCO held up publication of its revised business reconstruction plan for FY2024 over delays in restarting Kashiwazaki-Kariwa NPP. The restart is essential for improving TEPCO finances, but local approval is uncertain.
  • The utility faces rising costs from the Fukushima Daiichi cleanup, with the total now at ¥23.4 trillion, up from an initial estimate of ¥6 trillion. Despite plans to have two Kashiwazaki-Kariwa reactors operating, safety issues caused delays.
  • TEPCO expects a loss of ¥520 billion by March 2025, its seventh consecutive year of losses. TEPCO’s fifth business plan must focus on accelerating the plant’s restart, and aim to improve public trust and profitability through restructuring.
  • In a provisional update, TEPCO requested an extra ¥1.9 trillion in state aid to cover rising costs. TEPCO’s reliance on public funds continues to grow, raising concerns about the financial burden on taxpayers.
  • TEPCO’s attempts at business restructuring and attracting capital have had limited success. The only significant achievement has been JERA. Other efforts to diversify and strengthen revenue have fallen short. To regain financial stability, TEPCO must not only restart Kashiwazaki-Kariwa, but reduce dependence on nuclear power and state support.

OCCTO reports on status of FY2025 supply plan 

(Agency statement, March 19)

  • OCCTO reported its outlook for power supply in FY2025 (and through FY2034); this includes assumptions around impact of severe weather on supply and demand and the influence of reserve margins on balancing.
  • OCCTO says that demand for electricity should continue to increase through FY2034, due to economic growth, and new data centers and semiconductor factories; their impact is expected to be greater than the impact of population decline and energy conservation measures.
  • In terms of the supply-demand balance, there’ll be years when supply reliability is not certain in some areas, which will require measures such as additional capacity market auctions and adjustments to the timing of power plant repairs.
  • As far as balancing capacity, OCCTO sees annual fluctuations due to the retirement, as well as construction, of thermal power plants; but, overall the balance is expected to remain at FY2024 levels. Also, the power mix of coal, LNG-fired thermal power and pumped storage power is expected to stay largely unchanged.
  • In response to robust summer and winter demand, OCCTO expects to secure the minimum required reserve rate of 3% in all areas, taking into account increased supply from thermal power, inter-regional volumes, and dispatchable power sources during periods of high demand.
  • The agency expects few changes in supply-demand management in the context of the reserve margins as they stand. 
  • CONTEXT: Each March, OCCTO publishes the “Supply Plan” in its annual report. 
  • SIDE DEVELOPMENT:
  • OCCTO to prepare long-term policy for cross-regional grid
  • (Agency statement, March 21)
    • With a view to formulating the third long-term cross-regional grid system policy, OCCTO will examine the following issues:
  • Review of long-term outlook for cross-regional grid development
  • Update guidelines for renewal of aging facilities
  • Evaluate and implement renewals of interconnection facilities
  • Study congestion management on trunk and local grids (with an eye on the future needs of a simultaneous market)
    • These discussions will be in tandem with ANRE, EGC and TSOs; not just OCCTO.
    • CONTEXT: OCCTO has formulated the “Long-term Policy for the Cross-regional Grid System” for the development and renewal of the nationwide grid systems. This includes the ideal state of the nationwide grid systems over a 10-year period and how to achieve it. The first version dates to March 2017; it was reviewed in March 2023. It now must be rethought in light of recent changes, such as the 7th Basic Energy Plan.

Japan retail electricity sales dip; new entrants reach 20% market share

(Denki Shimbun, March 24)

  • Total electricity retail sales in December 2024 slid 1% YoY to 64.8 TWh. New market entrant suppliers (shin denryoku) increased sales 17.4% to 13.0 TWh, reaching a market share of 20.1%, up 3.1 percentage points from a year earlier.
  • The big power utilities, EPCOs, saw sales decline 4.7% to 51.8 TWh, marking a continued erosion in their market share.
  • Total electricity contracts rose 0.2% YoY to nearly 90 million accounts, with new entrants accounting for about 20.4 million contracts (up 3%).
  • Regionally, sales by incumbent utilities declined in most areas, notably 7.7% in Tohoku and Kyushu, and 5.3% in Chugoku; while Okinawa saw a 6.2% increase.

NTT Anode Energy inks off-site corporate PPA with NTT Urban 

(Company statement, March 26)

  • NTT Anode Energy will supply renewable energy through an off-site corporate PPA to four commercial properties owned by NTT Urban Development, including Shinagawa Season Terrace and WITH Harajuku.
  • About 9 MW of newly developed solar capacity across multiple sites will supply about 10 GWh annually.
  • CONTEXT: The buildings in the deal need between 4 GWh and 17 GWh of a year. The commercial offices sector has been one of Japan’s most active at inking PPA deals and pursuing 100% RE goals.
  • SIDE DEVELOPMENT:
  • NTT Anode Energy expands solar PPAs
  • (Company statement, March 27)
    • Starting April 1, NTT Anode Energy will supply 6.2 GWh of renewable electricity annually, from newly developed 5.8 MW solar plants, to battery maker Energywith via an off-site corporate PPA.
    • Energywith’s Saitama facility will achieve 100% renewable energy coverage for its total annual consumption of 41 GWh.

 

NEWS: HYDROGEN

  • Japan and South Korea held the 2nd Hydrogen and Ammonia Cooperation Dialogue on March 26 in Tokyo, agreeing to deepen collaboration in supply chains, certification, international standards, and safety.
  • The countries will establish a Japan-Korea platform led by private organizations to promote hydrogen and ammonia supply chain development and utilization.

Cosmo Energy, Shizuoka Univ study green hydrogen by seawater electrolysis

(Company statement, March 26)

  • Cosmo Energy Holdings and Shizuoka University began a joint study of green hydrogen production using seawater electrolysis.
  • If successful, the project could produce green hydrogen at less cost.
  • CONTEXT: Cosmo Energy is working to develop CCS and CCU. The company uses large amounts of seawater in oil refining and has seawater pumping facilities. Shizuoka University has developed and patented technology for producing hydrogen by electrolyzing seawater.

TAKEAWAY: Seawater electrolysis is a process where electricity is used to decompose seawater (H2O + dissolved salts) into its constituent elements: hydrogen (H2) and oxygen (O2). Using seawater could be a boon because of the abundance of the resource as compared to limited freshwater resources, but corrosion from salty water has prevented this development to date. Still, the need for switching to seawater has been questioned by many sources due to the additional costs involved, the additional energy use, and other challenges.

Ammonia-fueled tugboat completes successful demo

  • CONTEXT: HTGRs offer improved safety and can supply high-temperature heat without CO2 emissions; thus it’s a promising source for large-scale hydrogen production.

 

NEWS: SOLAR AND BATTERIES

Kansai Electric to build one of Japan’s largest battery storage facilities

(Company statement, March 25)

  • Kansai Electric plans to build two large-scale battery storage facilities in Sapporo, with a combined output of 100 MW and a total storage capacity of 351 MWh, which would be among Japan’s largest.
  • The facilities, named SGET Sapporo 1 and SGET Sapporo 2, will each have 50 MW of volume and 175 MWh of capacity. The lithium-ion battery containers will be supplied by Sungrow Power (China). 
  • Construction begins in March 2026, with operations set for April 2028. Partners include Sparx Group and JA Mitsui Leasing; Toshiba Energy Systems will oversee construction and battery procurement.

ANRE: control functions of home storage batteries to support DR

(Government statement, March 21)

  • ANRE proposed control functions for home storage batteries that would support demand response (DR).
  • For communication, an appliance will be able to link with the gateway in the same way as a heat pump, and with the DR server using a structured data format.
  • For external control functions, the DR server will be able to issue charge/ discharge commands with target values and durations for power to the appliance, as well as monitoring the amount of charge, and returning the appliance to its own mode after DR control. The server would also monitor the amount of power needed for backup.
  • As with heat pumps, the appliance must pass security requirements and be on the labeling system (JC-STAR). 
  • CONTEXT: The “DRready Study Group” was launched in June 2024 to examine the DR requirements for equipment and appliances. Because DR requirements vary by each appliance, discussions began with heat pump water heaters, which are expected to become more prevalent and consume large amounts of electricity. 

JR Kyushu leads initiative to tackle abandoned small solar plants

(Company statement, March 25)

  • JR Kyushu, Mitsubishi UFJ Trust Bank, Fuyo General Lease, and Girasol Energy have launched “Hyakunen Solar Kyushu,” a business initiative aimed at acquiring and consolidating small to medium-sized solar power plants in Kyushu to ensure their stable, long-term operation and address abandonment risks.
  • Hyakunen Solar Kyushu plans to acquire 10 MW of solar power capacity in the Kyushu region by 2027.
  • The project will be funded with investments from the four companies, alongside financing from regional banks such as Higo Bank.
  • CONTEXT: Small and medium-sized solar power plants, with a capacity of less than 1 MW, account for 90% of Japan’s total, but there are concerns that they will be abandoned after the 20-year FIT period expires.

Japan mulls 12-hour daily limit for battery charging to ease grid integration

(IT Media, March 20)

  • CONTEXT: The govt is discussing how to speed up connection of more energy storage batteries to the grid. There is concern that adding a lot of new battery capacity at once could destabilize the energy system’s flow.
  • One idea is a standard daily maximum for charging, at 12 hours nationwide. Operators that agree would then see their grid applications processed faster.
  • Under the proposed guidelines, battery storage operators subject to these restrictions would retain eligibility to participate in capacity and balancing markets, although failure to meet market requirements due to charging restrictions won’t exempt operators from penalties.
  • Grid operators in turn will be asked to provide, in advance, battery storage developers with detailed hourly grid-flow data, enabling accurate assessments of potential charging limitations before finalizing connection agreements.

TAKEAWAY: METI is reviewing a number of strategies that would give grid operators leeway with how they treat BESS in times of network congestion. These include the use of “non-firm” contracts through which battery facility operators agree to restrictions on charging at times of grid congestion. METI wants to avoid making restrictions excessive, otherwise BESS won’t be able to play its role in balancing the market. However, officials also seem keen to retain a degree of control, especially over peak periods. Where BESS facilities are unable to meet their obligations in the capacity / balancing markets explicitly due to grid issues, the onus may fall on the grid operator to invest in network upgrades.

Smart Energy enters battery maintenance business

(Nikkei, March 27)

  • Smart Energy entered the battery storage maintenance business. It will maintain three large BESS at the JRE Fukuchi Daisan solar farm in Fukuoka Pref.
  • As of January, Smart Energy was maintaining 4.6 GW of solar power capacity. By the end of FY2025, it targets contracts to maintain 300 MW of battery storage.

NEWS: NUCLEAR

HEPCO plans to restart Tomari NPP 1-2

(Nikkei, March 26)

  • Hokkaido Electric (HEPCO) revealed plans to restart Tomari NPP Units 1 and 2 in the early 2030s. By FY2035, HEPCO aims to achieve an operating profit of over ¥90 billion. If the restarts go forward then HEPCO expects electricity rate reductions.
  • As for Unit 3, HEPCO completed the explanations for regulatory approval, and it expects approval within the year, aiming to restart Unit 3 in early 2027.
  • HEPCO also announced its investment strategy through FY2035. It will allocate ¥400 billion over the next decade for carbon-neutral initiatives. It will allocate ¥250 billion for next-gen energy sources like hydrogen and ammonia.
  • CONTEXT: The combined capacity of Tomari Units 1,2,3 is 2.07 GW; they covered over 40% of Hokkaido’s electricity demand before the Fukushima accident. Since then, all units have been offline. By FY2035, HEPCO plans for nuclear power to account for 60–70% of its energy mix.

TAKEAWAY: As TEPCO’s example shows, nothing can be taken for granted in these plans for nuclear reactor restarts. HEPCO’s numbers look promising and could make it one of the most valuable power utilities in the country (see this week’s Analysis section for more details), but the company’s applications for a restart of Tomari NPP have been repelled by the regulator multiple times. As covered in previous Analysis texts by Japan NRG, no nuclear reactor restarts are likely within the next two years. HEPCO’s early 2027 guidance seems overly optimistic.

NRA gives approval for long-term management plan at Takahama NPP

(Company statement, March 27)

  • KEPCO received NRA approval for its Long-Term Facility Management Plan for Takahama NPP Unit 1. The plan addresses aging measures.
  • CONTEXT: Nuclear reactors operating beyond 30 years must be assessed every 10 years, at which point a Long-Term Facility Management Plan must be produced and accepted by the NRA.

NEWS: CARBON CAPTURE & SYNTHETIC FUELS

METI eyes competitive bidding for CCS transport and storage

(Government statement, March 28)

  • The latest meeting of the METI working group on how best to support the carbon capture and storage (CCS) sector suggested the govt considers introducing a competitive auction system to allocate funding for CCS transportation and storage projects. The aim is to reduce costs and foster market competitiveness.
  • Consortiums would consist of emitters and transportation/ storage operators bidding on a per-ton of CO2 transportation and storage fee. Carbon capture costs at emission sites, which vary significantly by industry, wouldn’t be included in auction criteria.
  • Auctions could be held annually, beginning in the early 2030s, to slowly scale up CCS projects. Maximum bid prices would be capped to reflect realistic costs, expansion potential, and project risks.
  • The govt should seek to introduce a transparent funding framework to supports CCS operators based on the difference between CCS costs and so-called industry-standard CO2 mitigation expenses, aiming to eventually phase out state support as the CCS sector costs become competitive.

TAKEAWAY: The development of business models for CCS in Japan is still at a very early stage. Early signs indicate that METI is keen to deploy more of contract-for-differences and actions approaches used for other energy sources. The annual auction cycle would give predictability for CCS operators.

METI Forges Ahead on ‘Simultaneous Market’ Plans to Boost Renewables Integration

To improve electricity market efficiency and create a system capable of reliably accommodating greater renewable energy penetration, METI is conducting an in-depth review on introducing a simultaneous electricity market (同時市場) – a fundamentally new approach to power trading in Japan.

In a simultaneous market, generation and consumption of electricity are balanced in real-time, optimizing dispatch and pricing through a centrally coordinated system. This approach integrates electricity supply and balancing services into a unified framework capable of effectively managing real-time volatility in both production and demand. Additionally, it facilitates better coordination among various ancillary and reserve services, potentially reducing the costs associated with balancing power procurement.

Implementing such a system will necessitate significant structural changes in electricity bidding processes, market offers, and methods for securing adjustment volumes. Although inspired in part by the PJM (Pennsylvania-New Jersey-Maryland) system – the largest independent system operator (ISO) in the U.S. – METI’s deliberations on the simultaneous market are already entering their third year. Nevertheless, recent discussions indicate increasing confidence that Japan can successfully adapt and implement this market structure.

The most recent METI committee meeting, held last week, focused extensively on detailed presentations regarding market design options, international comparisons, and strategic implementation considerations. Japan NRG takes a closer look at the simultaneous market debate within the broader context of Japan’s evolving electricity market reforms.

What is PJM and its impact on Japan?

The PJM system operator utilizes a nodal pricing system (also known as locational marginal pricing or LMP) to determine wholesale electricity prices. This reflects the cost of supplying an extra unit of energy at a specific location (node), considering grid constraints. 

Under this system, each node on the grid can have a different electricity price, influenced by factors such as generation availability, transmission capacity, and congestion. PJM centrally coordinates dispatch using detailed real-time data, enabling economically efficient operations and clearer price signals for investment in generation and transmission infrastructure.

Traditionally, Japan has utilized a regional-based market system rather than nodal pricing. Prices are uniform across broad geographical zones, and detailed locational constraints (congestion and transmission limitations) are typically managed through administrative measures rather than direct market signals. 

The introduction of a simultaneous market in Japan would represent a shift from that broader, regional price approach to more granular, node-based price signals. It essentially means using market-based solutions over administrative interventions to alleviate network constraints.

Background: Market reforms

Before METI started power market liberalization, Japan’s electricity system was a vertically integrated monopoly, with 10 regional power companies (EPCOs) controlling the entire process of generation, transmission, and distribution of electricity. 

This system’s advantage was that with exclusive control over their regional areas, the EPCOs ensured a stable power supply. The downside was that it inhibited competition. Pricing and investment decisions were regulated by METI, and consumers had no choice of electricity provider. 

Japan fully liberalized retail electricity sales in 2016, which has allowed over 700 new companies to enter the power market and compete with the EPCOs, mostly on the retail side. Market-based platforms to trade electricity were rolled out, primarily on the Japan Electric Power Exchange (JEPX), which manages the Spot Market, Intraday Market, Baseload Market, and Non-Fossil Fuel Value Trading Market.

Later, other platforms were added to mimic physical power systems. The OCCTO-operated Capacity Market helps to secure availability of power plants several years from now. This system was expanded two years ago with a Long-Term Decarbonization Power Source Auction and Standby Power Source System, expanding the option of securing capacity to the short-, middle- and long-term. Finally, in 2024  the Electric Power Reserve Exchange (EPRX) took on the trading of all balancing power services, which cover last-minute adjustments to available supply to ensure it meets demand.

Even with these reforms, challenges still persist. For example, generators say they need stronger investment incentives, especially for low-carbon capacity, and for improving system stability. The EPRX was designed to help Transmission System Operators (TSOs) buy balancing reserves more efficiently in a competitive setting, instead of relying only on their own resources; but major TSOs, particularly Tokyo and Chubu, largely avoid using the platform. 

Instead, the big utilities continue to secure balancing reserves using traditional methods such as internal power adjustments or direct contracts. They claim that this is down to:

  • Difficulty in predicting power demand and supply, especially with solar generation;
  • Existing contracts that do not assume full use of EPRX;
  • Preference for internal control instead of relying on an external system.

Recent updates in power market reform

On January 27, 2025, METI proposed an action plan to review the power market reforms so far and set future directions. A special working group will be created under the Electricity and Gas Basic Policy Subcommittee to review new necessary regulatory and policy changes, including possible amendments to the Electricity Business Act.

The reform plan is divided into three major areas:

Mid-to-Long-Term Supply Security Mechanisms

  • Increasing investment incentives for new power generation
  • Strengthening mechanisms such as the Feed-in-Premium (FIP), Long-Term Decarbonization Power Source Auction (LTDA), and the capacity market to ensure adequate power volumes
  • Encouraging investment in renewable energy and battery storage to improve long-term stability

Development of New Electricity Price Indexes and Trading Markets

  • Creating futures markets, forward contracts, and bilateral Power Purchase Agreements (PPAs) to provide more price predictability for electricity retailers and generators
  • Developing stable procurement methods to reduce price fluctuations and help financial planning for market participants

Short-Term Trading and Balancing Markets

  • Strengthening spot and balancing markets to increase operational efficiency.
  • Introducing the Simultaneous Market
  • Considering integrating the capacity market with the balancing market to improve procurement efficiency

The discussions cover a broad range of issues, but METI expects them to lead to formal policy recommendations by late FY2025, with possible law revisions taking place in 2026.

Simultaneous Market discussions

The METI study group that seeks how to set up a simultaneous market (同時市場) has now held two meetings, the latest on March 24. The group spent much of early deliberations reviewing the broader market reforms in the country and how a simultaneous market would fit within that. Even today, one of the key areas of debate is around pinning down the precise definition of what such a market is and how far its reach should be.

As an example, one of the areas under review is what to do with self-scheduled generation (自己計画電源) – power plants whose start-up/ shut-down and output is determined independently by their operators, rather than by market dispatch instructions. As such, operators have discretion whether to submit information on their status.

As TSOs seek to optimize dispatch and run the grid efficiently, avoiding congestion, they’d like to incentivise self-scheduled generation to report the details of their operations. But some of these self-scheduled generators work under bilateral contracts.

Mandating the generators to bid on the simultaneous market (and share their operations) would raise transparency but also create legal and accounting issues. For example, how would they account for the difference between the market and the contract prices? Even if the generators simply share the plant status information without selling power via the market, new rules will be required to ensure compliance with grid reliability and operational constraints.

The above is one of a plethora of discussion points outlined by METI’s study group, but it shows how the group’s workings has started delving into the practical matters that all market participants will face once a simultaneous market opens.

METI’s group has explored how the mechanism works overseas, referencing similar markets established in Europe and North America, particularly Germany and the U.S.; international experience shows differences in application across jurisdictions.

So, while a simultaneous market would be designed to balance real-time supply and demand, there is a debate over the exact scope of services this market should cover. Should it include services such as frequency control (周波数調整) and synchronous reserve (同期予備力)? Or act as a comprehensive framework capable of quickly and flexibly managing short-term imbalances? Even the application of a real-time market (リアルタイム市場) has to take into account the specific grid infrastructure and regulatory environment of Japan.

The group also has concerns about fairness and transparency, cautioning against scenarios in which established players might gain undue advantages, or where price mechanisms might unintentionally discourage market entry by innovative renewable energy producers. These require adjustments to the regulations, clearer price signals, and ways to encourage the market entry of innovative new technologies.

Of course, one thing is clear: the introduction of a simultaneous market would require more sophisticated real-time information systems, advanced monitoring and control technology, as well as significant upgrades to the electricity grid. The cost of such upgrades have yet to be estimated but they will be substantial.

Challenges and next steps

Given the size and scope of the changes, a major challenge will be convincing all the public and private stakeholders of the cost-benefit of this shift. The study group recommended pilot projects and phased implementation strategies to test, refine, and gradually demonstrate the market’s effectiveness.

As for the next steps, the group plans to conduct detailed simulations and economic modeling to quantify potential market impacts and benefits, while keeping an eye on best practices abroad.

The group recognizes the significant potential benefits of enhancing grid reliability in Japan with an eye to greater renewable energy integration, and more market-driven signals, but their outlook is one of optimistic caution due to the significance of the reforms.

The lackluster performance of the EPRX and the backup reserve markets shows how important incentives are to ensure a broad set of market players buy in. Even in the more popular markets, like the LTDA, there are tensions between big utilities like JERA and the government.

Often, it seems like reforms of this scale move along at a snail’s pace, with the adoption of the simultaneous market not expected for another three or more years. Given what’s at stake, the steady nature of the deliberations may well be justified. And the time to engage with METI on the planning should be now.

Japan’s Electricity Companies Are Cheap and Getting Cheaper

Japanese firms are the cheapest electricity stocks in the G7 — and the gap in market values is widening.

The average major electricity company in Japan is worth 10 times less than one in Europe, and 1/15th the value of one in the U.S., according to a review by Japan NRG. The market capitalization of the top American utility, NextEra Energy, is enough to buy all 10 Japanese regional power holdings — as well as the country’s top electricity wholesaler — three times over.

The differences are not due to the size of generation assets. NextEra Energy has only about 12% more capacity than TEPCO Holdings, the main supplier to the Tokyo area, but it’s 30x more valuable. NuScale Power, a U.S. firm that has yet to build a single working reactor, is worth 30% more than Kyushu Electric, utility with four reactors (total capacity 4.14 GW) online today, as well as dozens of thermal and renewables assets.

In the past twelve months, this divergence has accelerated with Japanese power utility stocks losing value, despite lower fuel costs, while peers in Europe and the U.S. gained. This potentially makes Japanese firms more of a target for M&A as well as significantly hindering their fund-raising capabilities at a time when investments in the grid and clean energy are imperative.

U.S. MARKET

S&P’s Dow Jones U.S. Utilities Index (White) vs S&P’s 500 Index (Blue)

Year-on-Year Return: 19.2%

  • U.S. utility stocks enjoyed a robust rally over the past year, easily outperforming their global peers. The S&P 500 Utilities sector index climbed roughly +20% in price​ from a year ago and as much as +25–27% total return including dividends. This surge made utilities one of the best-performing S&P 500 sectors in the timeframe.
  • Drivers:
  • As the Federal Reserve paused and eventually began signaling rate cuts, bond yields stabilized or fell from 2023 highs. This made the utilities’ relatively high dividend yields attractive again, sparking investor interest in defensive, income-producing stocks.
  • Unlike in Europe, the U.S. economic outlook in late 2024 included some growth concerns (raising recession odds) – this actually helped utilities, as investors rotated into defensives in anticipation of a slowdown
  • Company-specific boosts included NextEra raising dividends, Consolidated Edison selling non-core assets, and Duke Energy streamlined operations by exiting foreign markets

EUROPEAN MARKET

Country Weighting in the STOXX Europe 600 Utilities Index

Source: Stoxx

  • European utility stocks have been rocked by a number of factors over the past year, both in terms of the region’s macro outlook and global energy policy turbulence. Still, a recent rally in Europe pushed the biggest utility index, the STOXX Europe 600 Utilities, close to the YoY gains of the U.S. market as Germany’s willingness to relax its debt ceiling and optimism on trade led gains.
  • Drivers:
  • Unlike the U.S., Europe’s rate hikes persisted through 2023 (ECB rates peaked in mid-2024), which raised borrowing costs for utilities (typically heavy debt issuers) and made their high dividends less attractive. When the outlook shifted to economic recovery and central banks began signaling rate cuts, investors rotated away from defensives like utilities toward cyclicals.
  • Fuel prices, especially for natural gas, stabilized in 2024 and even receded in the latter half of the year thanks also to a milder winter 2023/24. This led to lower input costs but also lower retail prices, reducing revenues at a time when some of the European energy firms were still dealing with windfall profit taxes and price caps.
  • EU policy support for green energy (e.g. faster permits for renewables, EU Green Deal investments) benefited utilities pivoting to wind/solar. And while firms such as Orsted faced setbacks on large offshore wind projects due to higher costs and financing challenges, European governments started to raise the subsidies offered via capacity auctions.

JAPANESE MARKET

Year-on-Year Return: -5.5%

TOPIX-17 Electric Power & Gas Index

Year-on-Year Return: -5.4%

JPX Electric Power & Gas Index

  • Japanese utilities had a bad year, with nearly all EPCOs losing value over the past 12 months. One major headwind for power indices has been the performance of Tokyo Electric (TEPCO), which has lost about half of its value in the last year due to the further deterioration of its financial condition. Still, TEPCO is not the only utility to suffer in the past 12 months. The shares of Kansai Electric, now Japan’s most valuable power company, are down 14% YoY despite the utility operating all of its nuclear reactors. Other large power firms also saw double-digit drops with only Shikoku Electric and J-Power (previously known as Electric Power Development Co) able to post a positive return. The Nikkei 225 Index is down 7.6% in the past 12 months – less than the drop for most power utilities.
  • Drivers:
    • Oddly enough, most of the drivers for EPCOs are positive, which makes their share performance even stranger. The introduction of favorable wheeling charges and changes to the Balancing Market rules are expected to improve the profitability of the major power companies, which control about 80% of the electricity supply in Japan.
    • Fuel costs declined during 2024: LNG prices in yen terms were down 1.5% YoY and thermal coal prices down 6.2% in January while the dollar-yen exchange was largely unchanged at about ¥150. Meanwhile, most of the EPCOs raised rates in March 2025.
    • The big drag on the sector remains TEPCO. Tokyo’s main utility is unable to restart its only operable nuclear power plant while continuing to pay out vast sums each year for decommissioning work at the Fukushima Daiichi NPP and for disaster compensation. Earlier this month, TEPCO published a new business plan that forecasts a ¥960 billion shortfall over the next two years despite an expectation that profit will double. The erosion of TEPCO’s capital base is at a level where it continues to operate solely at the discretion of the state. The government took a controlling stake after the Fukushima disaster.

The power sector’s performance contrasts with that of gas utilities. Tokyo Gas has shot up by 40% YoY thanks to an expanded shareholder returns policy and an investment in the company by the activist fund Elliott Management. But other large gas firms have recorded positive growth on the back of improving financials and expectations of higher demand for the fuel from industry.

Japan Power Sector Outlook

The Bank of Japan is due to raise rates even further this year, which traditionally would have been a drag on power stocks as utilities tend to raise capital through bond sales. However, the arrival of higher rates is helping to revive investor appetite for utility bonds, which until now offered miserly returns.

What’s more, power companies may be willing to switch their capital raising to equity. Kansai Electric raised over ¥379 billion through a secondary share offering in November 2024, seeking capital for investments in data centers, renewables assets and overseas operations. That’s an unusual move in the sector and may now be echoed at other companies.

The biggest event in the sector remains the often-promised initial public offering by JERA, the top utility by generation capacity and the biggest Japanese importer of LNG. As JERA approaches investors, however, it hopes to persuade them that its valuation should be based in reference to utilities overseas rather than domestic peers.
