VARIATIONS IN AREA-SPECIFIC AND TIME-SPECIFIC MARGINAL CAPACITY COSTSOF ELECTRICITY DISTRIBUTION

Marginal costs of electricity vary bg time and location. Past research ers attributed these variations to factors related to electricity gene ration and transmission, Those authors, however, did not fully analyze the large variations in marginal distribution capacity costs (MDCC) b y area and time. Thus, the objectives of this paper are: (1) to propos e: a method to estimate MDCC; (2) to demonstrate the significant intra - and inter-utility variations in MDCC; and (3) to discuss the usefuln ess of these cost estimations in integrated resource planning.
