The deregulation process of power systems is on its way. The Northeast regional electricity market began to run, though still simulated, at the beginning of this year. The transmission service plays very important role in the northeast region. It is a critical problem to make a reasonable and practical transmission pricing solution in order to optimize the economic resources distribution. Based on the characters of the northeast power grid and the market operation mode, the calculation of transmission cost is analyzed and the transmission pricing methods are studied in this paper.The physical and operational characters of 500 kV power grids in Northeast region are discussed and the demand of the transmission pricing in northeast regional electricity market is drawn out from the practical stage of electricity market and the market scheme.The whole framework of the transmission pricing problem is divided into three parts in this paper on the deep review to this research area. Firstly, the calculation methods and calculation prerequisites of the transmission cost components are analyzed. The main factors influencing the calculation are discussed from various views. A practical strategy for cost evaluation is presented. Secondly, three transmission pricing patterns, which are energy price, are compared with the flexibility and the effect on the whole market. Finally, six transmission pricing methods, such as postage Stamp Method, MW-Miles and marginal cost, etc., are compared and discussed. Also some main effective factors which have important significance for making pricing mechanism are analyzed simultaneously.To help to fully understand the differences among the pricing patterns, a lot of calculation jobs are accomplished in this paper. Many practical calculation methods are applied to the 500kV grid in Jilin province. The results are helpful and significant. Based on the results, many critical questions such as fix cost evaluation, loss apportionment and some related questions are clearly explained.A recommended solution for the transmission pricing, including the pricing patterns and the pricing methods, in the northeast regional electricity market is drawn out from the above analysis. Considering the existing troubles and requires, a strategy of adopting different solution in each stage of the northeast regional electricity market is suggested. Some focus questions including the statistics of cost data, the returns of investments and the amount of transmission capacity are discussed and the solutions are given.To give the transmission pricing solution in the regional electricity market is an important and intricate scientific problem. Some helpful attempts are made in this paper. Though the contribution of this paper is very primary, it could give some reference and guidance to the following research work and help the northeast regional electricity market develop orderly.
