enechain to Offer eSquare Live for JEPX Next Year, Enabling Intuitive and Seamless Order Placement for Japan's Day-ahead and Intraday Power Markets

August 21, 2025

TOKYO – enechain Corporation today announced the upcoming launch of "eSquare Live for JEPX," an intuitive and powerful tool that enables businesses to trade for both the Day-ahead Market and Intraday Market to members of the Japan Electric Power Exchange (JEPX). This development comes as JEPX plans a comprehensive system update in 2026, which will lead to the discontinuation of its graphical user interface (trading screen) for the Day-ahead Market and Intraday Market. With "eSquare Live," our online trading marketplace for wholesale electricity, enechain will enable one-stop trading for both short-term (JEPX Day-ahead/Intraday) and medium- to long-term physical and financial futures products. Pre-orders for the service commenced today.

 

Since the full deregulation of the retail electricity market in 2016, JEPX has been designated by the Ministry of Economy, Trade and Industry as the sole wholesale electricity exchange in Japan. It operates the Day-ahead and Intraday Markets, serving as a crucial trading platform for many electricity businesses. However, with the planned system upgrade in 2026, JEPX will no longer offer the trading screens for the Day-ahead and Intraday Markets. This necessitates that businesses either apply for dedicated lines and develop their own trading functionalities or prepare for trading through third-party services or systems with equivalent capabilities.

 

In response to this situation, enechain has decided to develop and offer "eSquare Live for JEPX," leveraging the expertise gained from developing and operating "eSquare Live" to provide trading functionalities for JEPX's Day-ahead and Intraday Markets.

 

Businesses already using "eSquare Live" will be able to seamlessly trade in the JEPX market directly from the "eSquare Live" screen, enabling one-stop trading of short-term (JEPX Day-ahead/Intraday) and medium- to long-term physical and financial futures products.

 

Furthermore, JEPX trading member companies can subscribe to "eSquare Live for JEPX" without onboarding "eSquare Live." It offers a user experience similar to JEPX's current trading screen, while also providing numerous highly demanded features from businesses that will reduce trading effort and enable management of trading history. In the future, APIs are planned to be released, allowing trade execution results to be integrated into other systems used by businesses.

 

"eSquare Live for JEPX" can also be utilized for business continuity by companies planning to develop their own trading systems or those already placing JEPX orders via supply and demand management systems, ensuring readiness in the case of their own system failures.

 

Features of eSquare Live for JEPX:

  • Supports batch processing of large orders via CSV, particularly in the Day-ahead and Intraday Markets, enabling CSV bidding for block orders* and orders spanning multiple areas.

  • Integrated management of transaction history from execution to settlement.

  • Supports both Japanese and English.

  • Allows viewing of availability of Interconnector Capacity in the Intraday Market. Its API will no longer be available after the JEPX system update, but availability can still be checked on eSquare Live for JEPX.

  • Enables to manage account permissions and access at an individual user level.
