从“照付不议”到“可靠容量”：中国容量电价三十年

Core Viewpoint - The establishment of a comprehensive capacity pricing mechanism for power generation in China marks a significant evolution in the country's electricity pricing system, transitioning from investment protection to system reliability assurance [6][8]. Group 1: Origin and Evolution - In the 1980s, China faced severe electricity shortages, prompting the introduction of the "take-or-pay" contract model to attract foreign investment in independent power plants, providing stable cash flow expectations for investors [2]. - The first successful implementation of this model was seen in the Shenzhen Shajiao B power plant in 1987, which set a precedent for future projects [2]. Group 2: Exploration Phase - The early 2000s saw a shift towards systematic exploration of capacity pricing, with the 2004 notice from the National Development and Reform Commission (NDRC) establishing a two-part tariff for pumped storage power stations [3]. - In 2015, the central government called for the establishment of a market-oriented capacity compensation mechanism, laying the groundwork for future developments [3]. Group 3: Breakthroughs in Mechanism - From 2020 to 2022, local pilot programs and national-level designs advanced the capacity pricing mechanism, with Shandong province launching the first provincial-level capacity compensation mechanism under a power spot market [4]. - The 2023 notice from the NDRC and the National Energy Administration established a unified capacity pricing mechanism for coal power, with fixed cost recovery rates set to increase from 30% in 2024-2025 to no less than 50% in 2026 [4][6]. Group 4: New Regulations and Framework - The 2026 regulations expand the compensation scope to include independent new energy storage and allow provincial authorities to establish capacity pricing for gas power generation [6]. - The new market-oriented approach aims to ensure fair compensation for different power sources based on their peak capacity contributions, moving from government-set prices to market-driven pricing [6][7]. Group 5: Strategic Shift - The evolution of the capacity pricing mechanism reflects a strategic shift in the electricity sector from addressing investment shortages to ensuring system reliability, particularly in the context of increasing renewable energy integration [8]. - The modern capacity pricing mechanism emphasizes the importance of compensating for the availability of power generation assets, ensuring that traditional power sources can support the energy transition effectively [8].
