 Durgapur
Projects Limited's total power generation capacity
after the recent renovation and upgradation, today
stands at 401 megawatt (MW). It is engaged in all
the three functional areas of a power utility -Generation,
Transmission and Distribution. It generates and
distributes power in an uninterrupted mode at grid
frequency. It has a cluster of six generation units
of different capacities. The largest unit is of
110 MW capacity followed by three of 77 MW each
and two of 30 MW each. Two boilers are of B&W,
UK make, two of B&W, USA make. The remaining
two boilers are of Mitsubishi and ABL. Except one
of BHEL make, all other five generators are supplied
by Siemens. The coal input for all the six units
taken together is 6669 tonnes per day. The power
tariff it offers to all its end users, is reasonably
cheaper than many other power utilities in the country.
The growth in power in the DPL command area is
around 20% per annum, the current demand being
around 120 MW which is about 30% of the total
power generation capacity of the utility. It meets
local demand through its captive transmission
and distribution networks.
