JEPX and N-SIDE mark six months of successful collaboration improving Japan's Energy Market

The partnership between the Japan Electric Power Exchange (JEPX) and N-SIDE has reached its six-month milestone in operating Japan's day-ahead electricity market. This period has demonstrated how effective collaboration can support the continuous operation of critical market infrastructure while adapting to evolving needs.

Maintaining Operational Stability

Since April 2024, the day-ahead market has maintained its essential role in Japan's electricity sector, with consistent daily operations supporting market participants nationwide. The transition to the new market-clearing solution proceeded smoothly, allowing JEPX to continue providing reliable service while implementing necessary adaptations.
JEPX and N-SIDE have achieved several operational enhancements, including improved handling of complex bid types and refined market clearing processes. These developments reflect JEPX's commitment to maintaining a robust trading platform that serves the needs of Japan's energy community.

Supporting Japan's Energy Transition

Japan's energy market is undergoing a significant transformation as it strives to reach its national target of achieving a 36-38% share of renewable energy by 2030.  This transition brings specific challenges, particularly in managing grid congestion and integrating variable renewable energy sources.
The day-ahead market plays a crucial role in this evolution, helping to allow the most cost-efficient supply to meet the demand with the highest utility while accounting for physical grid constraints. JEPX's market platform, supported by the N-SIDE clearing solution, facilitates this goal by enabling effective price formation and efficient resource allocation.

Building on Shared Experience

The past six months have provided valuable insights into Japan's energy market characteristics. This collaboration has demonstrated how technical capabilities can effectively support market operations combined with deep market knowledge and careful attention to operational requirements.

Looking Forward

JEPX and N-SIDE are dedicated to advancing Japan's energy market through their ongoing partnership. Their primary focus is on maintaining operational excellence while also preparing for future market demands. This includes a strong commitment to supporting the integration of renewable energy sources and adapting to the changing dynamics of the market.
The insights gathered during these early months lay a solid groundwork for our ongoing partnership, reflecting the commitment of both organizations to work together in promoting the efficient operation of Japan's energy market.
