The trading schedule for the medium- and long-term electricity market in Northeast China now spans every calendar day. The region has become the first in the country to implement daily continuous trading simultaneously at both the inter-provincial and intra-provincial levels.
This advancement was driven by the Northeast Energy Regulatory Bureau. It aligns with the requirement to "achieve continuous trading and uninterrupted transactions, and increase trading frequency and flexibility" set out in the Implementation Opinions on Improving the National Unified Electricity Market System.
In recent years, the proportion of new energy installed capacity in the Northeast power grid has continued to rise, with marked fluctuations and intermittency in wind and solar output. The need for cross-provincial resource complementarity and flexible adjustment has thus become acute. To address this, the Northeast Energy Regulatory Bureau began building a power mutual support market system, establishing two trading products: "multi-day continuous inter-provincial medium- and long-term trading" and "inter-provincial power mutual support," which entered trial operation in the second half of 2025.
After reviewing the trial experience, the bureau guided the trading institutions to formally shift to daily continuous trading starting April 27, 2026, with a principle of serving market participants and improving operational efficiency.
This daily continuous trading mechanism is expected to yield multiple benefits. It can help quickly smooth out fluctuations in new energy output and supply-demand gaps caused by extreme weather, thus enhancing supply flexibility. Higher trading frequency can boost the ability to absorb new energy and increase revenue for generators. It also enables various market participants to dynamically adjust their traded electricity volumes based on supply and demand forecasts, reducing assessment risks from forecast deviations.
Going forward, the Northeast Energy Regulatory Bureau will follow the deployment of the National Energy Administration to further deepen the construction of the Northeast regional electricity market, promote synergy between the energy and ancillary services markets, and guide new types of market entities to enter in an orderly manner.
