Jiangxi Completes Its First Hourly Matched Trade in Distributed Green Power

State Grid Jiangxi Electric Power Co., Ltd. recently completed its first hourly matched trade in distributed green power, becoming the first provincial power company in the State Grid system to do so. The transaction extends green power trading in Jiangxi to distributed renewables, enabling hourly matching of supply and demand across all types of centralized and distributed renewable generation.

In the transaction, a company in Jiangxi purchased 7.2 MWh of distributed green power from an electricity retailer. The system matches output from distributed generators with the company’s electricity consumption profile hour by hour. It also uses State Grid’s blockchain technology to issue time-stamped certificates of green power consumption. The certificates record where and when each kilowatt-hour was generated, so the information can be verified and the power traced throughout the process.

To meet exporters’ needs for traceable green power and for matching generation and consumption times, State Grid Jiangxi Electric Power Co., Ltd. has continued to improve resource aggregation, time-based matching, and data coordination. It has improved recordkeeping, metering, and the management of market entry data for distributed generation projects and linked registration, trading, and settlement procedures. The company has also worked with local energy authorities to integrate distributed generation into the existing trading system for hourly matched green power.
