The global trend towards increased urbanisation requires municipal bodies to provide services
such as streetlights, solid waste management, sewage treatment & disposal, etc.
All these activities consume significant amount of electricity, usually in an inefficient manner.
The cost of energy sometimes constitutes more than 50% of the municipality’s budget and implementing
efficiency measures could reduce it by at least 25%. There is a potential to save around 10 billion
rupees by implementing energy efficiency measures. Almost all municipal bodies depend on government
support to meet their development and operating expenses. Government of India, through
the Bureau of Energy Efficiency has initiated a programme to cover 175 municipalities in the country
by conducting investment grade energy audits and preparation of detailed project reports.
Energy Service Companies are being encouraged to take up the implementation of the programme
with the help of financial institutions. Utility must encourage
implementation of DSM measures to relieve their network of such inefficient load.
Energy saving opportunities for Municipal Corporation:
The major energy loads in a municipality are typically the water pumping
systems, street lighting, sewage treatment and Municipal buildings such as offices,
hospitals, schools also contribute to the high municipal energy bills. Therefore,
the following sectors have high potential of energy savings in Municipal Corporation.
Replacement of inefficient HPSV and Metal
Halide Lamp with energy efficient Lighting fixtures like LED,
T5 & Induction lamp.
Effective energy-efficient lighting design integrates efficient lamp technologies,
optimum pole height and placement, efficient light distribution and aesthetics while using the
and meeting requirements for visibility and appropriate light levels (NYSERDA, 2002)
The most common reason for inefficient
street lighting system in municipalities & others are:
- Selection of inefficient Luminaries
- Poor design and installation
- Poor power quality
- Poor operation & maintenance practices
There is a tremendous potential to improve lighting quality while
reducing energy use, costs, and GHG emissions-through energy-efficient
retrofits for street lighting and improved operation and maintenance (O&M) practices.
