DEVELOPMENT OF A 3-PART TIME-OF-DAY ELECTRICAL ENERGY TARIFF

This paper presents an analytical technique for determining peak, offp eak and midpeak hours tariffs for various durations of these three per iods. The technique considers the existing flat rate tariff, an hourly generation scenario of a utility on an average yearly demand day, the weighted average life time, annutised capital cost and fuel cost of b ase and peak load plants, and a break even point condition in the util ity's revenue. The developed tariff has been applied to 30 representat ive industrial consumers served by the Bangladesh Power Development Bo ard (BPDB) to estimate the minimum possible shift in consumption patte rn and hence corresponding reduction in peak generation capacity requi rement as well as peak time load shedding by BPDB.
