Japan Meteorological Corporation Launches New Price Forecast for Demand-Supply Adjustment Market

The Japan Meteorological Corporation (JMA) has announced the launch of a new service called the Demand-Supply Adjustment Market Price Forecast. Starting from January 22, 2026, this service aims to enhance electricity trading strategies and maximize revenue through high-precision price forecasts provided in 30-minute intervals.

This innovative price forecasting service supports energy-related businesses in optimizing their trading strategies within the demand-supply adjustment market (operated by EPRX). It focuses on predicting the auction prices of the third-level adjustment power every 30 minutes, ensuring that electricity providers can adapt their plans effectively in a market characterized by significant fluctuations.

Understanding the Demand-Supply Adjustment Market Price Forecast

The Demand-Supply Adjustment Market Price Forecast predicts the auction price of the third-level adjustment power for the next day, segmented into 30-minute blocks. This collaboration with existing services, such as the spot market price forecast, allows for a more comprehensive understanding of electricity pricing dynamics. By integrating weather prediction data along with uncertainty information, the forecasts have become significantly more reliable.

Considering the impact of renewable energy prediction errors on the adjustment power recruitment amounts, the service further refines these predictions to address the specific needs of the market. This precision is essential, especially when it comes to making informed decisions about market bidding and planning for the electricity distribution.

In addition, by incorporating spot market price forecasts, businesses can make strategic decisions about bidding in the demand-supply adjustment market depending on whether the predicted auction prices are higher than the previous day's spot market prices.

Context and Need for Enhanced Forecasting

Since its inception in 2017, JMA has consistently provided price prediction services primarily focused on wholesale electricity trading. However, the establishment of the demand-supply adjustment market in 2021, prompted by a surge in renewable energy integration and improved grid management, has necessitated a shift in focus toward this new market segment.

Given the uncertainties surrounding electricity prices due to climatic and demand variations, energy-related firms require highly accurate price forecasts to guide their bidding decisions and operational planning. The critical nature of these precise predictions becomes evident, especially when the financial viability of energy trading activities is at stake.
