The Discussion on the System of Cross-subsidization for Large User Direct Power-Purchase in Electricity Market

With the deepening of the reform of the electric power system in China, the system of Cross-subsidization for large users' direct power-purchase has achieved initial results. The domestic experimental work of large users direct Power-Purchase and the practice of foreign countries have demonstrated that " Large users direct power-purchase " is advantageous to construct the multi buyer - seller's market competition pattern, the construction of the competitive market and to speed up the construction of competitive market, "Large users direct Power-Purchase " is also help price to play a guiding role for the supply and demand of the market, which would timely reflect the real needs of the market. However, the experimental work revealed some urgent problems with the System of Cross-subsidization. Under this background, this paper deeply studies the key problems of the provincial Cross-subsidization for the large user's direct power-purchase. The research results of this paper can improve the implementation scheme of the large user's direct power-purchase and supporting mechanism. It also can further promote and ensure the implementation of the direct power-purchase laid the foundation to establish the competitive power market and realize the optimal allocation of power resources.
