Electricity network pricing methodologies play a key role in determining whether providing network services is economically beneficial to both the utilities and other m arket participants. There are many pricing methodologies that have been developed since the late 80's, especially for transmission networks. Compared to transmission pricing methods, distribution pricing methods are unsophisticated and pose a significant barrier to embedded generators. Hence, more efficient and executable methodologies are still desirable in open access electricity networks. This thesis presents a series of new long-run marginal cost (LRMC) pricing methodologies for both transmission and distribution networks, and demonstrates the processes o f evaluating and allocating the network asset costs. New reactive power pricing methods, based on the perpendicular approach and arc approach, have been proposed and demonstrated in these LRMC pricing process. Compared with other proposed LRMC pricing schemes, the novel long-run marginal cost with utilisation consideration (LRM C-Util%) pricing methodology aims to evaluate the network asset costs based on the usage o f the network facilities. It can reflect the future network investment and indicate the future location o f network users. The advantages o f LRMC-Util% include the ability to reflect the forward looking costs, to distinguish between the costs o f siting at different locations, to recognize o f the reactive power, and to derive charges for both generation and demand users.
