The Solar City aims at minimum % of reduction in projected demand of conventional energy through a combination of enhancing supply from renewable energy sources in the city and energy efficiency measures. In a Solar City all types of renewable energy based projects like solar, wind, bio mass, small hydro, waste to energy etc. May be installed along with possible energy efficiency measures depending on the need and resource availability in the city.

2. Why Solar ?
The most employment-intensive energy resource.
A fixed cost resource to balance variable cost fossil.
Private Investment to Leverage Public Dollars.
High-Reliability.
Clean & Green.
Renewable source.

3. Solar City
• The Solar City aims at minimum % of reduction in projected
demand of conventional energy through a combination of
enhancing supply from renewable energy sources in the city
and energy efficiency measures.
• In a Solar City all types of renewable energy based projects
like solar, wind, bio mass, small hydro, waste to energy etc.
• May be installed along with possible energy efficiency
measures depending on the need and resource availability
in the city.

4. Objectives
• To Create a Self-sustained City.
• Green & Energy Efficient City.
• To enable and empower Urban Local Governments to address
energy challenges at City-level.
• To provide a framework and support to prepare a Master Plan
including assessment of current energy situation, future demand
and action plans.
• To involve various stakeholders in the planning process.
• To oversee the implementation of sustainable energy options
through public & private partnerships….Etc.

5. Selection of cities - Solar city
The City is identified based on ;
• City population.
• Potential and commitment for adoption of renewable energy & Energy
conservation in the city activities.
• Initiatives already taken by City Council / Administration/ Private
Developers / Industry / General.
• Public in promoting renewable energy and energy conservation,
regulatory measures taken on deployment of renewable energy
technologies and their willingness to provide resources and sustenance of
activities initiated under the program.

7. Solar City - India
• The “Development of Solar Cities” programme by the
Ministry of New and Renewable Energy (MNRE) GOI is an
immense opportunity for contributing towards a sustainable
India in the coming years.
• As part of the 11th Five year plan ,demand forecasting for the
years 2013 and 2018, this programme is a crucial step
towards supporting Indian cities for the development of
renewable energy and energy efficiency projects and curbing
conventional energy demand by 10% in the next five years.

8. Cities to be developed as Solar cities
• The Proposals received and the cities identified by some of the
State Governments so far are 48 cities, Sanctions have been given
to 31 cities.

9. Master Plan for Solar city
• To create “Solar City Cell” & constitute a “Solar City Stake Holders
Committee”
• To promote National Rating System for construction of energy efficient
Green Buildings in particular to commercial and institutional buildings
• To organize rigorous publicity, and also the training programmes/ business
meets for various stake holders.,e.g..architects, engineers, builders &
developers, financial institutions, NGOs, technical institutions,
manufactures/suppliers, Resident Welfare Associations (RWAs) etc. so as to
involve them actively in meeting the objective of solar city.
• To generate necessary funds from State Govt. and other funding
organizations for achieving the objective of making the city as “Solar City”.

10. Case Study - Agra as Solar city
• City is situated in Western U.P
• It is 27.11' degree Latitude North & 78.0' degree Longitude
East.
• Its Altitude is 169 meters above sea level. It is situated on
the bank of Yamuna River.
• Maximum Temperature in Summer is 45oC & minimum
temperature is about 21.9oC and
• In inter maximum temperature is 31.7oC & minimum
temperature is about 4.2oC.

11. City Urban Services
• Administrative Services,
• Water Supply,
• Solid Waste Generation – 628 MT/Day,
• Street Lights – 28,048
• Public Health,
• Education – 1500 Centers,
• Town Planning

21. Mastering Solar city as Coimbatore
• Coimbatore, National Earth Hour Capital of India 2014, is one of 36 cities that
has finalized its solar city master plan as part of its participation in India’s
National Solar Cities Programme.
• The plan includes the goal to reduce conventional energy consumption by 10%
within five years, through investment in renewables and energy efficiency
measures.
• As a first step, the city has started to install solar photovoltaic panels (PVs) on all
municipal buildings, and is completing its energy-saving project for street lights
by using timers, dimmers, electronic meters, and LEDs.

22. Conclusion
• Many cities around the world are setting targets and
introducing polices for promoting renewable energy
and reducing GHG emissions, India might get added
upon that list.
