According to "Energy Storage and Power Market," on October 10, the Guangdong Provincial Development and Reform Commission and the Guangdong Provincial Energy Bureau issued the "Notice on Matters Concerning the Launch of Mechanism Electricity Price Bidding for New Energy Projects in 2026," formally starting the 2026 mechanism electricity price bidding process.

The notice specifies the scope of projects for this bidding: distributed photovoltaic projects that were put into operation or committed to be put into operation between June 1, 2025 and October 31, 2027 and that have not yet been included in the mechanism, while offshore photovoltaic projects listed as provincial development pilots will be handled under separate provisions.

The rules on the bidding upper and lower limits, power volume scale, and other aspects are as follows:

Bidding upper and lower limits: The upper limit for photovoltaic project bidding is 0.40 yuan per kilowatt-hour, and the lower limit is 0.20 yuan per kilowatt-hour. The basic unit ratio for price declarations has been adjusted from 1% to 0.1%.

Power volume scale: The initial bidding scale for mechanism electricity is 7.934 billion kilowatt-hours (calculated on a full-year basis). To ensure the validity of the bidding results, a competition validity check will be carried out before price clearing. The cleared scale of mechanism bidding transactions is determined by the smaller value between the initial mechanism electricity bidding scale and the declared electricity scale divided by the competition validity coefficient, which is 1.2 this time.

Mechanism ratio: The upper limit of the bidding electricity declaration ratio for distributed photovoltaic projects below 110 kilovolts is 80%, while the upper limit of the declaration ratio for other distributed photovoltaic projects is 70%.

Implementation period: The implementation period of the mechanism electricity price for photovoltaic projects is 12 years.

Formula for calculating the mechanism electricity of a single project. For distributed photovoltaic projects, mechanism electricity ≤ installed capacity × average annual power generation hours of that type of power source × upper limit of declaration ratio (including self-generated and self-consumed electricity). The specific settlement electricity is executed according to the project's actual on-grid electricity and the requirements of the difference settlement rules.

Compared with Guangdong Province's 2025 bidding situation, this bidding has not adjusted the upper and lower price limits or the implementation period, but the mechanism electricity has risen from 5 billion kWh to 7.934 billion kWh, an increase of 58.68%. According to the 2025 mechanism electricity price bidding results, the implemented electricity price ultimately reached 0.36 yuan/kWh, with a total of 4.65 billion kWh of electricity included in the mechanism scale.
