In the scope of the move towards the implementation of market mechanisms, new tariffs schemes are necessary in order to remunerate the transmission service. Several tariffs in use include marginal based terms that, however, may be very dependent on load levels or load uncertainties. In this paper we present a fuzzy set based approach to deal with load uncertainties in order to compute local marginal prices. This approach is based on a DC fuzzy optimal power flow algorithm integrating an estimate of active losses. This algorithm is finally integrated in a Monte Carlo simulation tool in order to obtain estimates of average nodal prices considering component outages.
