BDPP , a public sector agency under the
Government of Kerala, that generates and
distributes the electricity supply in the state.
The plant is controlled by Kerala load
Distribution Center(KLDC)
KLDC decides whether to produce or to buy
power(whichever profitable)

LSHS is in semisolid form, it is heated by steam
to make it liquid form.
When melts it becomes the same form of
diesel.
The transfer of diesel to LSHS is done by a
three valve mechanism(first diesel, then a
mixture of diesel and LSHS, then LSHS)

MAINTENANCE DIVISION
There are totally five units of machines which
are similar.
Either two or three will be in work and the
others remain idle.
Once any problem occurs to the working unit,
it is shut downed and the idle unit is operated

Most common problems which require
maintenance
Corrosion of piston.
Bending of crank
Burning of piston ring
All the above problems mainly occur due to the
idleness of machine

Switch gears of 220kv, 25000 A are used to
control the supply.
Then the load is reduced to 11kv for
transmission, with the help of step down
transformers
