Gandhinagar Solar PV Rooftop Programme

• The Gandhinagar Photovoltaic Rooftop Programme marks the first distributed power generation programme in India in its true sense.

• Brings Together True Public Private Partnership:

Objective of the Solar PV Rooftop programs

• Accelerating the harnessing and penetration of solar energy in the state

through distributed means.

• Empower each household/consumer of electricity to be an environmentally

conscious contributor to energy security and sustainable development of

the state.

• Promoting efficient and cost-effective solar installations by providing fiscal

and non-fiscal incentives.

• Broad-basing the solar energy development in the state by harnessing the

participation of large set of stakeholders, tapping local capabilities and

entrepreneurial abilities and allowing for innovation and competitiveness.

• Creation of environmental consciousness among citizens.

13


Advantages of the Solar PV Rooftop programs

• Carbon Emission Reduction

• Reduction in water consumption

• Insulating benefits

• Increases House value

• Encourages further energy efficiency

• Durable and Reliable

• Minimal maintenance

• Increases energy security through distributed generation

• Minimal line loss

• Reducing the need for peak load stations

• Create jobs

• Optimizes land usages

• Encourages wider adoption

14


Milestones of the Solar PV Rooftop programs

• Callifornia has more than 1 GW solar rooftop installations

• Germany’s solar capacity has grown 500% since 2007. The German

government recently announced a 52-gigawatt target for rooftop solar

capacity, to be achieved over the next 3-4 years.

• Japan, Australia are also encouraging solar PV rooftop programs

15


Aim of Gandhinagar Solar PV Rooftop Program

• Gandhinagar Photovoltaic Rooftop Programme aims for…

– 5 megawatt of photovoltaic installations- in two clusters of 2.5

MW each

– in distributed kilowatt-sized photovoltaic systems

– through a PPP mode

– to promote clean energy and energy security

– as a part of the Gandhinagar Solar City Initiative.

• Greater outcome of this pilot Programme:

– Establish a practice/ philosophy of distributed solar and other

energy generation.

– Bring a level of comfort to all stakeholders for further scale-up.

– Encourage public participation.

– To reduce T & D losses

16


• Operative Period – Gujarat Solar Power Policy : upto year 2014

– JNNSM-2nd Phase : from 2013 to 2017

• Eligible units and Capacity– Residential households , Commercial buildings , Industrial Clusters etc,

• Project Identification– Nodal Agency identified

– Self Identified

• Sale of Energy– As per the GERC order

Key Discussion points for a Rooftop Solar Power PolicyContd.

Key Discussion points for a Rooftop Solar Power PolicyContd.

• Metering– Net-metering and energy settlement arrangements

• Electricity Duty– Benefits to consumers having high level of Electricity Duty and

Consumer Tariff applicability

• Possible Incentive Options– Capital Subsidy

– Generation Based Incentive-GBI

– Green incentive

– Feed-in Tariff

18


Pathways for Rooftop Solar PV Projects

1. For Captive Power with/without grid-feed

GERC may specify requisite changes in the Distribution Code and outline the net-metering

and energy settlement arrangements to encourage the net-metering based captive rooftop

solar projects.

2. Third Party Sale

Third Party Sale will be eligible as per Electricity Act 2003 and regulations of GERC

3. REC Mode

Project developer may sale electricity generated at a price not exceeding the pooled cost of

power purchase of such distribution licensee

19


MW Vs Rooftop Solar Plants

• Per MW cost of Rooftop Solar PV systems are HIGHER

than large-scale PV Power plants because :– Installation costs and cost of balance of systems in larger scale plants

can be optimized

– Lease of rooftops in urban area is higher

• Key Benefits of Rooftop SPV projects :– Avoids cost due to savings on T&D network losses

– Avoids Cost due to savings on Transmission Infrastructure related costs

and land costs
