7.1. Coal Consumption

The generating unit uses coal from the collieries of Central Coalfields Ltd. (CCL). The coal is transported through road over a distance of about 34 to 49 kms. The completion of MGR system to transport coal is delayed and efforts are being made to complete this as early as possible.

The normative levels are far from the ground situations experienced by most plants in India. The normative level of heat rate may be applicable for the stations operating at high level of efficiency and high plant load factor.
Tenughat Thermal Power Station is operating under various constraints.

Momentary outages due to tripping of transmission lines.

Outages due to other reasons.

Backing down of the units under instructions of JESB due to lack of load.

Year	Specific Coal Consumption (kg/kWh)	Heat Rate (kCal/kWh)

2010-11	0.700	3000

The transport of coal on a bumpy road in fully loaded trucks is resulting in loss of coal by spilling from the trucks. In addition, there is loss due to wind, evaporation of moisture, during rainy season the coal powder gets washed out. All these factors result in loss of coal in transport and storage. The coal is weighed at loading end and at receiving end, the difference accounts for loss in transit. The experience has shown that the loss accounts to about 0.3 % of coal transported. TVNL requests the Honourable Commission to allow 0.3 % of total coal transported towards transit loss in FY 2009-10.

7.2 Specific Consumption of Oil

The specific consumption of secondary fuel (oil) is projected below:

7.3. Fuel Prices and Costs

Petitioner projects landed cost of coal at Rs 1477 per MT and delivered cost of oil is expected to be at the level of Rs.43269 per kL.
The cost of coal and oil consumption based on the projected prices for FY 2010-11 and consumption worked against the electricity generation results in an aggregate fuel cost of Rs.315.55 Crores for FY 2010-11 as detailed in the Table below:

The proposed variable/energy charges of Rs.315.55 Crores and expected net generation of 2507 MUs results in energy tariff charge of Rs.1.259/kWh for FY 2010-11. The Petitioner requests the Hon’ble Commission to kindly approve this.
