Inner Mongolia's power multilateral trading market has completed its first multi-month trading session, marking a new step in the region's medium- and long-term power trading framework.

The trading, organized on August 20, used remaining monthly electricity volumes from September through December as the underlying asset, attracting 313 power generators, 938 power users and 38 electricity retailers. Total traded volume reached 5.07 TWh at an average price of 282.3 yuan/MWh.

The new multi-month product, added on top of existing annual and monthly trading, is designed to strengthen the medium- and long-term trading mechanism, soften rigid supply-demand signals from short-cycle trading, and provide new market entrants with access to longer-term contracts. It is expected to support price stability and supply security.

Inner Mongolia Power Exchange Center said it had drafted implementation rules for multi-month trading, which were reviewed by the market management committee and approved by supervisory authorities. The rules specify trading cycles, models and applicable scope.

Traded volume from generators already in the market this year reached 2.17 TWh, accounting for 42.82% of the total. The basic contract signing rate for power users for September-December rose to 70.19%, significantly improving medium- and long-term contract coverage.

The exchange said the successful launch of multi-month trading supports the national requirement for full signing of medium- and long-term power contracts and helps ensure stable and orderly market operations.
