Core Viewpoint - The era of easy profits in the renewable energy sector, characterized by fixed pricing and government subsidies, is over. The new market-oriented pricing mechanism will challenge companies to adapt to fluctuating electricity prices and market dynamics [1][2]. Industry Overview - The introduction of market-based pricing for new renewable energy projects starting June 1 has created uncertainty among companies accustomed to government-set prices. This has led to concerns about a potential decline in new installations and increased market hesitance [1]. - The share of wind and solar power in total electricity consumption exceeded 20% in the first quarter, indicating rapid growth but also increasing pressure on the stability of the power system. The new policy aims to encourage companies to optimize their operational models and address the challenges of scaling up [1]. Market Dynamics - Short-term fluctuations in electricity prices may create anxiety for power generation companies, especially during periods of oversupply. Companies lacking flexible trading strategies may face profitability challenges [2]. - Long-term, the market-driven approach is seen as an opportunity for transformation within the industry. Technological advancements have significantly reduced the costs of solar and wind energy, driven by competition rather than subsidies [2]. Competitive Landscape - The market's core logic emphasizes survival of the fittest, where companies with lower costs and superior technology will thrive. Innovative practices, such as peak-shifting transactions in Xinjiang, demonstrate how companies can adapt to market demands and enhance profitability [2]. - The transition to a market-oriented model will require companies to focus on technological innovation, operational efficiency, and market awareness to navigate the competitive landscape effectively [3]. Future Outlook - The future of the renewable energy sector lies in embracing market competition rather than relying on protective policies. Companies must prioritize technological strength, cost efficiency, and innovative business models to succeed [3]. - Regulatory bodies are encouraged to implement supportive policies to ensure a smoother transition to marketization, allowing companies to build resilience against market fluctuations [3].

Core Viewpoint - The introduction of the first national policy on green electricity direct connection aims to balance efficiency and fairness, facilitating the use of renewable energy and addressing challenges in wind and solar energy consumption [1][2]. Group 1: Policy Overview - The notification represents the first national-level policy for green electricity direct connection, incorporating both incremental and existing projects [2]. - Previous local government attempts in Jiangsu and pilot projects in Xinjiang have laid the groundwork for this policy, which now includes both new and existing renewable energy projects [2]. - Direct connection refers to power lines that connect energy sources directly to users, bypassing the public grid, with a clear physical trace of the supplied electricity [2]. Group 2: Objectives and Benefits - The policy aims to enhance the consumption of renewable energy by requiring that at least 60% of the annual self-generated electricity from direct connection projects comes from renewable sources, with targets increasing to 35% by 2030 [3]. - It addresses the growing demand for green electricity from users, particularly in high-energy industries, by facilitating a transition to low-carbon energy sources [3]. - The policy encourages cost reduction for users by allowing them to self-declare grid capacity and manage their own responsibilities, thus enhancing flexibility and lowering electricity costs [3]. Group 3: Fairness and Efficiency - Green electricity direct connection projects must comply with national regulations regarding transmission and distribution fees, ensuring that local governments do not waive these fees [4]. - The policy promotes the self-regulation of direct connection projects to increase the proportion of self-generated renewable energy, thereby reducing reliance on the public grid and lowering operational costs [4]. - It allows projects to participate in the electricity market, optimizing their energy consumption patterns while ensuring compliance with energy supply requirements [4].
