What kind of output (charts, data) can I obtain?

You can output information such as position, exposure, cash flow (revenue and expenses), average unit price, market value, and EaR. All data can be downloaded in CSV format, allowing you to freely process it into internal reports using Excel or other software.

In addition to wholesale procurement and retail contracts, can power sources (thermal power, battery storage, solar power) also be included in the portfolio?

Yes, it is possible. We can accommodate this by linking additional modules according to your portfolio. In addition to the value of trading flexibility offered by thermal power plants, battery storage, and swing options including constant backup, we can also perform risk assessments that take into account risks specific to variable renewable energy sources such as solar power (uncertainty of power generation due to weather, correlation between power generation and market price).

Do you handle not only spot trading but also futures trading?

Yes, it is supported. In addition to calculating the overall EaR (Earnings at Risk) of the portfolio, it also supports VaR (Value at Risk) analysis, which evaluates the amount of loss incurred if futures positions are held for a certain period of time.

Can you handle fuel cost adjustment unique to your company, other than those provided by former general electricity utilities?

Yes, we can accommodate that. We can offer flexible settings, including not only the All Japan Customs Clearance Price but also linkage to fuel price indices such as Henry Hub (HH), JKM, and NEWC.

How far into the future can we measure the risks?

Forward pricing can be measured without any time limit, as long as a forward price exists for that period.

Entering data into the system seems complicated; can I choose the method of integration?

You can choose between CSV upload or API integration. We also provide a sample tool for API integration using Excel as the interface.

How much time and preparation is required for implementation?

No special preparation is required on your end. We will provide a dedicated cloud environment, so you can start using the service immediately by simply logging in with your ID and password via a web browser. Typically, setup and full implementation are completed in a short period of about two months. During the setup period, we will support you with everything from registering your portfolio data to becoming proficient in using the system.

Do you offer a trial?

We offer a trial where you can experience the actual operation and analytical functions in a dedicated environment for your company. Please contact us for details.

Service Overview

Challenges faced by electric power companies

"Both power generators and retail electricity providers face price fluctuation risks (wholesale electricity prices and fuel prices) on both the sales and procurement sides, but as portfolios become more complex, it is not easy to visualize the impact of these fluctuations on their financial balance."

Solution by MPX-ETRM

By entering your company's sales and procurement contract information once, you can quickly visualize risk indicators such as Net Exposure¹ and EaR² (the range of financial fluctuations).

1. An index representing the amount of price fluctuation risk among each index (such as the Japan Electric Power Exchange spot market price, the All Japan Customs Clearance LNG/Coal/Crude Oil Price (JLC/J-Coal/JCC)).
2. Abbreviation for Earnings at Risk.

Risk assessment that is also adapted to the latest trends in the power industry(Examples below)
- Expanding imports of US LNG
- In recent years, Japanese companies have increasingly concluded long-term contracts for U.S.-sourced LNG¹, and domestically, bilateral power transactions incorporating the Henry Hub (HH) price² into fuel cost adjustment clauses have also been on the rise³.
- MPX-ETRM enables the assessment of price fluctuation risks for a variety of fuel price indices, including HH, as well as JKM⁴ and NEWC⁵.

  2. A representative benchmark for natural gas prices in the United States; the reference value for natural gas futures traded on NYMEX
  3. Denki Shimbun, “Chubu Electric Power Miraiz to Reflect U.S. Gas Benchmark in Fuel Cost Adjustment / Revises Extra-High and High-Voltage Tariffs” (December 1, 2025)
  4. A spot LNG price benchmark for Northeast Asia
  5. An Australian coal spot price benchmark
  *However, due to data usage rights, customers are required to provide price data for indices other than the All-Japan customs-cleared price (e.g., HH, JKM, NEWC).
- Domestic policy trends
- Recently, the Agency for Natural Resources and Energy’s advisory committee has been discussing the introduction of a quantitative supply capacity obligation for retail electricity providers¹, as well as the establishment of a Medium- to Long-Term Trading Market².
- Going forward, retail electricity providers, particularly those that have primarily relied on spot market procurement, may face increasing diversification and complexity in their procurement portfolios; however, MPX-ETRM is capable of adapting to such changes.

Reflection of individual asset characteristics
(See examples below. Note that an additional option contract is required in addition to the basic module.)
- Thermal power plant
- By considering the specifications of each power plant (output, power generation efficiency, minimum operating/downtime, startup costs, etc.), it is possible to evaluate how much a power plant's revenue may fluctuate in response to changes in the spot market price of electricity and fuel prices, assuming optimal operation of the power plant.
- Renewable energy
- In addition to market price uncertainty, the profitability of renewable energy sources is evaluated by considering the uncertainty of power generation and the correlation between market price and power generation.
- Swing contract
- For swing contracts (wholesale contracts in which the deadline for exercising volume adjustment rights is set close to delivery), it is possible to evaluate the economic value of optimizing the exercised volume of such contracts while taking into account the uncertainty of electricity spot market prices.
03

Labor saving
- The latest price data, such as electricity prices and fuel prices, is automatically imported.
- Compared to risk management using Excel, etc., this method significantly reduces the workload of on-site personnel.
