Core Viewpoint - The "Green Power Direct Connection" policy is an innovative approach to address the dual challenges of energy transition and carbon tariff barriers, aiming to enhance the efficiency of clean energy utilization and improve the physical attributes of green electricity [2][3]. Group 1: Systematic Advantages - The policy establishes a localized framework compatible with international rules, allowing for clear physical traceability of renewable energy consumption, thus addressing the moral issues associated with "greenwashing" [3]. - It defines "Green Power Direct Connection" as a model where renewable energy sources supply electricity directly to a single user without connecting to the public grid, enhancing clarity in energy sourcing [3]. - The policy introduces a dual-track mechanism that ensures the safety and stability of the public grid while granting market entities greater autonomy, transforming electricity from a "generic commodity" to a "low-carbon passport" [3]. Group 2: Market and Transaction Innovations - The policy breaks away from traditional green electricity trading models by introducing a "physical direct connection + market settlement" approach, allowing for a more accountable and transparent trading environment [4]. - It mandates that connected projects participate equally in the electricity market, ensuring that the electricity generated is accounted for and settled based on market transactions [4]. - The policy aligns with broader goals of integrating renewable energy into the electricity market, facilitating a more efficient and high-quality development of the sector [4]. Group 3: Organizational Support and Development Models - The policy emphasizes the need for flexibility in projects to address the intermittent nature of renewable energy sources, encouraging the use of energy storage and load adjustment to enhance project adaptability [5]. - It places the primary responsibility for connected projects on the load, promoting investment from both load and power source entities to ensure the sustainability of the direct connection [5]. - The policy outlines specific requirements for project operation, including energy input ratios and exit mechanisms, to guide scientific assessments of demand and prevent discrepancies between design and actual performance [5]. Group 4: Challenges and Future Outlook - While the "Green Power Direct Connection" initiative presents significant opportunities, it also poses challenges related to construction costs, market uncertainties, and the need for a robust regulatory framework [6]. - The initiative is seen as a trial to gather collective efforts from government, enterprises, and research institutions to enhance technological development and improve market mechanisms for efficient clean energy utilization [6].
