“风光大省”甘肃,为何竞配出了全国最低的机制电价?
Sou Hu Cai Jing· 2025-11-13 02:31
"136号文"发布至今,已有6省完成了增量项目首轮机制电价竞价。由于各地增量项目机制电价执行期限约为10—12年,可以说 这些竞价结果预示了各省新能源项目的未来境况。 华夏能源网统计,目前完成增量项目首轮机制电价竞价的省份分别为山东、云南、新疆、甘肃、江西以及广东,竞价结果如 下: 广东0.36元/千瓦时;江西风电0.337元/千瓦时、光伏0.33元/千瓦时;云南光伏0.33元/千瓦时、风电0.332元/千瓦时;新疆风电 0.252元/千瓦时、光伏0.235元/千瓦时;山东风电0.319元/千瓦时、光伏0.225元/千瓦时;甘肃0.1954元/千瓦时。 让人大惑不解的是,甘肃的机制电价竟然垫底了。无论是新能源装机更多的新疆,还是"光伏第一大省"山东,机制电价都高于 甘肃。如果不出意外的话,甘肃的机制电价很可能会在全国垫底。 文 | 华夏能源网 值得注意的是,甘肃"136号文"落地文件规定,新能源机制电价竞价上下限区间为0.1954-0.2447元/千瓦时,也就是说最后竞配的 机制电价是压着下限成交的。这也是其他省份所没有的情况。 | 省份 | 公示日期 | 竞价区间 | 增量机制电价 | 执行期限 | | - ...

Core Insights - The article contrasts India's frequent power outages with China's successful implementation of ultra-high voltage (UHV) power transmission technology, highlighting the importance of timely energy delivery rather than just resource availability [1][28]. Group 1: India's Energy Challenges - India faced a severe power outage in 2012, affecting 600 million people and exposing the inadequacies of its outdated power system [1]. - The Indian power grid is limited to 400 kV, lacking segmentation and protection, which leads to nationwide impacts from localized issues [6]. - India's energy distribution is inefficient, with abundant resources in the north and west but significant losses during long-distance transmission [7][9]. Group 2: China's UHV Solution - China has effectively utilized UHV technology to transport electricity from resource-rich western regions to the energy-demanding eastern areas, overcoming the challenges of energy distribution [3][14]. - The UHV technology allows for long-distance power transmission with minimal losses, making it a more efficient solution compared to traditional methods [9][20]. - The construction of UHV lines has been a monumental effort, involving thousands of scientists and workers over a decade, culminating in the first UHV line operational in 2010 [23]. Group 3: Environmental and Social Impact - UHV technology supports China's dual carbon goals by enabling the transmission of renewable energy sources, significantly reducing deforestation and carbon emissions [20][25]. - The UHV network ensures equitable energy access across China, reaching remote areas and providing reliable power even during emergencies [24][26]. Group 4: Comparative Analysis - The article illustrates a stark contrast between India's reactive approach to energy crises and China's proactive development of infrastructure, reflecting differing national development strategies [28].
