基于碳减排效益的西藏绿色水电外送上网电价定价机制研究

我国主要呈现由北至南、由西至东的跨区送电格局。从长景规划建设看,西藏水电将成为"西电东送"的中流砥柱。虽然新一轮电改提出发、售电环节市场化,但西藏厂网未分、水电建设成本高和远距离外送等特殊性决定了其不具备实行市场化的基础。由于缺乏配套上网电价定价机制,藏电外送面临极大挑战。为了进一步促进西藏水电开发及跨区送电的发展,本文统筹考虑水电的环境成本和在受电区的清洁能源价值,结合碳交易市场机制,并以综合因素法权衡现有上网电价定价机制的优缺点,提出基于碳减排效益的西藏绿色水电外送上网电价定价机制,为西藏清洁水电外送提供新定价参考。

Power generation pricing mechanism for trans-region power supply of Tibetan green hydroelectricity considering carbon emission reduction benefits

Most trans-region power supply in China is from north to south and west to east, and Tibetan hydropower will play a key role in west-to-east power transmission from the vision of long-term supply. Although the new electricity price reformation puts forward a project to realize marketization of electricity generation and sale, Tibetan hydropower is unsuitable yet for marketization due to its particularity? integrated plants and network, high construction costs, and very long transmission distance. Without an appropriate supporting pricing mechanism, power supply from Tibet to the outside is facing huge challenges. This paper suggests a new pricing method to promote the development of Tibetan hydropower and its trans-region supply, namely the power generation pricing mechanism for trans-region power supply of Tibetan green hydroelectricity considering carbon emission reduction benefits. This method considers the environmental costs and benefits of hydroelectricity and all the advantages and disadvantages of the existing pricing mechanism, thus providing a new idea of power pricing for power transmission from Tibet to the outside.
