  17. Green Incentive: Aid to Roof-owners ‘Green Incentive’ is the minimum generation-based incentive for participating Roof-owners specified by GoG. Advantages: Encourage awareness and participation among roof-owners. Will be correlated to home-owner’s electricity bill. Should not be compared to ‘constant’ (or ‘dead’) lease rental. Distributed Generation- ICORE 2013; 27 Nov. 2013 Distributed Generation- ICORE 2013; 27 Nov. 2013
  18. Future Outlook The Gandhinagar Solar Rooftop Programme is selected as on of the TOP 10 DEALS OF ASIA-PACIFIC by Infrastructure Journal. New Cities – 5-10 MW each: Bhavnagar Mehsana Rajkot Surat Vadodara Incorporation of Rooftop Photovoltaics at Policy and Regulatory Level. Explore different implementation models: Feed-in or net metering? Third party/ Developer driven or private ownership? Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  19. Learning of Critical Aspects How appealing is the Green Incentive? What is the value of my roof? How appealing is the Third-Party Model? Am I willing to sign a 25-year lease agreement? Why can’t I get the full benefit of my PV system? Interdependency of Contracts and Financial Closure: Lease Agreement  PIA  PPA. Implementation: Coordination between Statutory Bodies, Regulator, Chief Electrical Inspector, DisCom, Building Owners/ Govt. Departments, Developer, Financer, Project Management, Social. Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  20. Evolution & Implementation of Rooftop Solar PV Installations for Gujarat Model I: Capital cost borne by the Government Advantage: Ease of implementation, and widely implemented. Disadvantage: Ownership issues, and hence, maintenance suffers. Example: Most rooftop solar installations by various governments throughout India (including GEDA). Model II: Public Private Partnership Example: 5 MW Gandhinagar Rooftop Solar Programme. Advantage: Generation-based incentive ensures long-term utilization. Government interaction with limited number of credible Developers. Standard quality and optimization of PV installations. No upfront cost to Government/ Utility. Disadvantage: Property owners unwilling to sign long-term lease agreements. Incentives from solar generation not enough compared to real-estate lease. Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  21. Model III: Individual Ownership (Proposed in Current Rooftop Solar Policy) Advantage: Equal opportunity to smaller rooftop owners. Ownership of individual is well-defined. Investors reap the direct benefit of electricity and also become energy aware/ efficient. Investment yields definite returns. Potential for widespread public deployment. Successful model globally. Challenge: Investment expected from someone who does not understand technology. Capital subsidies required to incentivize participation (under net-metering scheme). Direct dealing of DisComs directly with Customers. Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  22. Policy Implementation: Preparatory Phase DisComs: Obvious focal agency Specify standards of interconnection and Net-Meter. Set up internal process viz. accepting applications for interconnection, PV system commissioning, regulatory compliance, billing. State Nodal Agency: GEDA Empanelment of Channel Partners/ Installers. Avail necessary funds from State Dept., Central Ministries. Act as a single-window for disbursing subsidies. Publicize and monitor overall progress. Channel Partners/ Installers Link between System Owners and DisCom/ GEDA for administrative procedures. Comply with relevant guidelines of safety, standard, performance outlined by DisCom, GEDA, MNRE, GERC, CEA, etc. Eligible Entities/ System Owners Only employ Channel Partners/ Installers empanelled by GEDA. Apply for interconnection of rooftop PV system. Comply with any other approvals/ clearances required from time to time. Shall be final beneficiaries of subsidies. Shall own and be responsible for operation of PV systems. Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  23. Policy Implementation: Preparatory Phase Rooftop Solar Policy is Launched. GEDA Empanels Channel Partners/ Installers. DisComs set up standards for Net-Metering. GEDA Educates Channel Partners with compliance requirements. DisComs set up internal processes for: Accepting and scrutinizing customer applications, and Commissioning PV systems. GEDA publically promotes Rooftop Solar Policy/Programme Channel Partners commence their own marketing. Distributed Generation- ICORE 2013; 27 Nov. 2013 Pulkit.d@germi.res.in
  24. Policy Implementation:Implementation Phase Eligible Entity contacts Channel Partner. Channel Partners undertak-es feasibility of installation. GEDA approves: Subsidy subject to fund availability, and PV System capacity subject to DisCom’s and CEI’s clearance. Eligible Entity, via Channel Partner, applies to GEDA for subsidy. CEI’s Approves: Capacity of installations Channel Partner installs rooftop PV system. Eligible Entity, via Channel Partner, applies to DisCom for interconnection. DisCom: Verifies installation, and Installs Net-Meter to commission the system. System Owner owns and operates the PV system. DisCom bills System Owner based on net consumption.
