【电新公用环保】持续推荐“反内卷”、雅下水电GIL及风电整机板块——电新公用环保行业周报20250803（殷中枢/邓怡亮）

Overall Viewpoint - The article emphasizes the continuation of policies aimed at promoting a unified national market and optimizing market competition, which is expected to have a lasting impact on the solar energy sector. The effectiveness of price support measures and the acceptance of prices by downstream power plants will influence the stock performance of related solar companies, particularly in segments with price elasticity such as silicon materials, glass, and BC batteries [3]. Solar Energy - The political bureau meeting has reiterated the importance of advancing the construction of a unified national market, which is expected to lead to a sustained "anti-involution" policy. The success of price support measures and the implementation of storage plans will be crucial for the stock performance of solar-related companies [3]. Hydropower - The market's understanding of Gas Insulated Lines (GIL) remains low, despite their necessity for interconnecting power stations and high-voltage transmission lines. The investment potential of GIL is significant, comparable to that of traditional hydropower turbines, with the first 550 kV C4 environmentally friendly GIL successfully put into operation by Pinggao Electric [3]. Wind Energy - Progress has been made in the provincial details of Document No. 136, with Shandong province planning its first bidding in August 2025. This is expected to improve bidding data across other provinces. Wind energy will also benefit from the "anti-involution" policy, with a general recovery in the bidding prices for wind turbine units anticipated in the first half of 2025 [3]. Solid-State Batteries - The outlook for solid-state batteries is positive, with a focus on fully solid-state battery equipment and lithium sulfide segments expected to benefit from new tenders initiated by major lithium battery manufacturers. The development of semi-solid batteries and modified electrolytes is also promising, aligning with the "anti-involution" logic and enhancing battery safety and technical standards [4]. Energy Storage - The recent introduction of pricing policies for large-scale electrochemical energy storage in Gansu is expected to counterbalance the gradual elimination of capacity leasing fees, improving the independent storage Internal Rate of Return (IRR). Other provinces are likely to follow suit, and the overall market for energy storage remains robust due to improved commercial models and high demand for energy consumption [4].
