Sr No. Check List Remarks
1
• Check the power bills raised by the State Electricity Board and locate if any
amount has been paid towards LPF (low power factor), surcharge on delayed
payment or any other payment in the nature of penalty. Such expenses can be
avoided.
2
• Ensure whether the consumption of electricity (in units) is within the contracted
demand because a penal amount is required to be paid if the contracted demand (in
KVA) is exceeded and a fixed sum has to be paid even if the actual consumption is
less than the minimum consumption guarantee. Both the situations i.e. exceeding
the contracted demand and consuming less than the minimum guarantee should be
avoided.
3
• Check the Water bills raised by the Water Department and ensure that the actual
consumption is neither more than the contracted demand nor less than the minimum
consumption guarantee. Penal payments have to be made if the contracted demand
is exceeded to or if the actual consumption is less than the minimum guarantee
consumption. Penal payments of any nature should be avoided.
4
• In case of Captive power plants (CPP) / DG sets it should be ensured that proper
records are maintained in respect of consumption of Diesel/ other consumables and
raw material. Power cost per unit should be worked out in case of CPP and
compared with the per unit cost of power of the State Electricity Board. It should be
the objective to balance the utilization of CPP and purchased power to get the
maximum benefit.
5
• The per unit cost of power of CPP should include the depreciation and interest
element. The per unit cost can be worked out by dividing the total cost of running
and maintaining the CPP (variable + Fixed) by the No. of units produced by the CPP.
