EnErgy SEcurity EffortS by Surat Municipal corporation

Surat Municipal Corporation (SMC) in line with the smart city mission, decided to undertake the project of energy conservation by meeting 10 per cent of its total energy requirement through solar
energy. SMC also focused on reducing its water supply system’s electricity consumption by using renewable sources of energy. Therefore, solar revolution under SMC kick-started with the launch
of solar roof top programme in September 22, 2016. With the motive of reduction of carbon footprint by conservation of electrical energy and by reducing the usage of conventional fuel/ energy,
usages, SMC implemented various Energy Efficiency (EE) measures in Water Supply System which have rendered 109.80 GWH per annum. This implies reduction of equivalent CO emission by
2
92,230 tonnes of CO2 per annum. Till date, all the energy savings realized through Energy Efficiency and Renewable Energy measures for the whole of SMC have rendered 116.25 GWH per annum.

Introduction Background
urat City was declared as a ‘Solar City’ in 2011 by Ministry of New and Renewable ater supply system’s electricity consumption is more than half of the electricity
SEnergy (MNRE) and being the model solar city it has been promoting solar energy and Wconsumed by entire Surat Municipal Corporation even after taking various energy
energy efficiency projects since 2013-14, even before it made it to the Smart Cities list in conservation measures. After detailed study, it was concluded that running water treatment

decided to undertake the project. It was estimated that of the rooftop potential of 11,924 sustainable and renewable energy based installation of wind power plant was taken up and

thus reducing conventional fuel/ energy sources usages, SMC implemented various Energy

As the size of the water supply system increased immensely, dedicated focus was also not
possible by the engineers involved in projects and operation & maintenance works of water

established in the Year 2001.

Key dates

Tof 240 MLD WTP at Katargam Water Works. Similar projects were also initiated at
Sarthana and Rander Water Works and the same were carried out till the year 2009. With
installation of 3 MW wind power plant in 2010 at Adodar in district Porbandar, Surat Municipal
Corporation became the first Urban Local Body in India to achieve such a landmark. Surat
