Generation tariffs
Capacity Vs Energy Deal
Generation tariff setting depends on whether payments relate to
energy generated or for the capacity available

Setting of bulk supply tariff
• The Bulk Supply Tariff (BST) is the price at which the transmission company sells electricity to
distribution companies.
• The BST is charged for peak, shoulder and off-peak time of use periods.
• It is based on the revenue requirement of UETCL which is derived as a sum of O&M, Net power
purchase costs, and debt service costs (No allowance for depreciation and return on equity) divided
by bulk energy sales by UETCL.
• Energy sales by UETCL is derived as energy purchased adjusted for transmission losses.
• The transmission company has been regulated under a Multi Year Tariff regime.
• There is incentives to increase efficiency; reduce costs and achieve energy loss target.
• Benchmarking is key & value for money assessment is necessary.
