Energy SavingEnergy Saving

Energy Saved is Energy Generated. Saving of Energy is the need of the day. Government is one of the major consumer of

Energy. The Govt. has to lead others by taking

effective steps to save the energy


278 million units of energy per annum are consumed by Maharashtra State Government Office Buildings

This is equal to 105 MW Generation during working hours under the assumption of 10 hours /day, 22 days /month, 12 months /year.

One unit saved is TWO units generated. Annually Rs.111 crores are spent by the

Government on energy bill .


Energy Efficient Lamps and Equipments can save energy bill up to 30 %.

100/60/40 watts bulbs can be replaced by CFL lamps of 22/11/9 watts having power factor more than 0.9.

40/36W Fluo. fittings can be replaced by 28W E+/T5 fluo. fittings or their chokes by electronic chokes.

Four pillars of successful Four pillars of successful Energy Management : Energy Management : Key Key ElementsElements

Successful energy management programme needs the total support of senior management.

The other important requirements are A well-charted strategy plan. An effective monitoring system. Adequate technical ability for analyzing and implementing energy

saving options.

In any organization, which does not already possess an energy efficient ethics, good communication downwards from senior officials will be vital first step.

Active participation & planning for the energy management

Ways of Energy Ways of Energy ConservationConservation

Awareness Replacement of conventional fittings with E+ fluo. fittings Replacement of conventional pumps with submersible

pumps/energy efficient pumps Replacement of old water coolers with energy efficient

water coolers Replacement of GLS lamps with CFL lamps Incorporating timers for passage lights Incorporating digi guards for ACs Incorporating DPSD for compound & street lights

Ways of Energy Ways of Energy ConservationConservation

Replacement of electric water heaters with solar water heaters

Replacement of water coolers with heat pumps Replacement of resistance type regulators with electronic

regulators Replacement of conventional chokes with electronic chokes Incorporating VFDs for hydro pneumatic systems, pumps &
