Customer Services - RTP Base Rate Calculation FunctionContentsNarrativeBase RTP Calculation function develops tables of load versus price for each “power system node” and for each “settlement” period (e.g. each hour). These tables are the Base RTP data. The purpose of this computation is to accurately forecast the cost of providing energy during the period. The RTP Base calculations are performed by the Market Operations actor after the Load Forecast function is complete to calculate the costs of delivering energy to customers during each of the settlement periods (usually 1 hour intervals) in the horizon of the calculations. These calculations are usually performed on a day-ahead basis so the information can be processed, transmitted to ESPs and finally to the RTP customer in time for action. RTP can be calculated or modified on an hourly basis if marginal cost warrant and customers are willing to subscribe and respond to such a service. The base calculation require from the Load Forecaster as well as costs information from a variety of sources. These costs include the fuel and variable costs associated with the generation unit that will serve incremental load, adjustments for line losses, a risk adders, and congestion fees. There is concerted effort in the industry to improve the speed and accuracy of the calculations for more timely and accurate pricing. Steps
