Core Viewpoint - The current limitation of transmission channels is a significant issue restricting the delivery of wind and solar power resources from Northwest China, despite the recent commissioning of the Ningxia-Hunan ±800 kV UHVDC project, which is the first of its kind focused on delivering renewable energy from large bases [1][2]. Group 1: Transmission Challenges - The existing transmission channels are insufficient, with a total capacity of 86.71 million kilowatts in the Northwest region, while the installed capacity of renewable energy has reached 305 million kilowatts, indicating a mismatch between supply and demand [6][7]. - The actual utilization of built transmission channels is lower than expected, with the proportion of renewable energy in the total transmission volume being only about 25.12% in 2024, far below the anticipated 50% [8][9]. - The complexity of approval processes for transmission lines, which involves multiple government agencies, contributes to delays in construction and planning, leading to a time lag between power generation and transmission capacity [7][8]. Group 2: Necessity of Power Delivery - The necessity of power delivery is highlighted by five key aspects: addressing spatial mismatches between energy resources and load, managing time-based fluctuations in energy demand, achieving cost-effective solutions for carbon neutrality, ensuring energy security, and promoting a unified electricity market [4][5]. - Local consumption alone cannot solve the problem due to limited demand in the Northwest and insufficient regulatory power sources, necessitating cross-province and cross-region power delivery [5][6]. Group 3: Pricing and Market Mechanisms - Negotiations on transmission pricing are complicated, with discrepancies arising from the differing expectations of sending and receiving provinces, often leading to conflicts in pricing agreements [15][16]. - The current pricing mechanism is primarily based on the receiving province's market price, which may not adequately reflect the sending province's costs, creating a disadvantage for the latter in negotiations [16][17]. - Suggestions for reform include establishing a two-part floating price system for transmission fees to better reflect market conditions and introducing transmission rights trading to account for congestion costs [18][19]. Group 4: Future Opportunities - The demand for transaction and consulting services in the power delivery market is expected to grow, as more private companies are emerging to assist power generation and consumption enterprises in developing pricing and trading strategies [19]. - The recent slowdown in investment from major power groups in renewable energy projects is attributed to the lack of system adjustment capabilities keeping pace with installed capacity, indicating a potential growth area for technologies that enhance grid stability [20].
