17 Green Incentive: Aid to Roof-owners  ‘Green Incentive’ is the minimum generation-based incentive for participating Roof-owners specified by GoG.  Advantages: o Encourage awareness and participation among roof-owners. o Will be correlated to home-owner’s electricity bill. o Should not be compared to ‘constant’ (or ‘dead’) lease rental. 17 Plot Size (Sq. m.) Built-up Area (60%) Typical Solar Area (30%) Typical PV Capacity (kW) Monthly Generation (kWh) Green Incentive Rs. 2/ Rs. 3/ Rs. 4/ kWh Distributed Generation- ICORE 2013; 27 Nov. 2013

18 Future Outlook  New Cities – 5-10 MW each: o Bhavnagar o Mehsana o Rajkot o Surat o Vadodara  Incorporation of Rooftop Photovoltaics at Policy and Regulatory Level.  Explore different implementation models: o Feed-in or net metering? o Third party/ Developer driven or private ownership? 18 The Gandhinagar Solar Rooftop Programme is selected as on of the TOP 10 DEALS OF ASIA-PACIFIC by Infrastructure Journal. Distributed Generation- ICORE 2013; 27 Nov

19 Learning of Critical Aspects  How appealing is the Green Incentive? o What is the value of my roof?  How appealing is the Third-Party Model? o Am I willing to sign a 25-year lease agreement? o Why can’t I get the full benefit of my PV system?  Interdependency of Contracts and Financial Closure: o Lease Agreement  PIA  PPA.  Implementation: o Coordination between Statutory Bodies, Regulator, Chief Electrical Inspector, DisCom, Building Owners/ Govt. Departments, Developer, Financer, Project Management, Social. 19 Distributed Generation- ICORE 2013; 27 Nov

20 Evolution & Implementation of Rooftop Solar PV Installations for Gujarat  Model I: Capital cost borne by the Government o Advantage: Ease of implementation, and widely implemented. o Disadvantage: Ownership issues, and hence, maintenance suffers. o Example: Most rooftop solar installations by various governments throughout India (including GEDA).  Model II: Public Private Partnership o Example: 5 MW Gandhinagar Rooftop Solar Programme. o 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. o Disadvantage: Property owners unwilling to sign long-term lease agreements. Incentives from solar generation not enough compared to real-estate lease. 20 Distributed Generation- ICORE 2013; 27 Nov

21 Model III: Individual Ownership (Proposed in Current Rooftop Solar Policy)  Advantage: o Equal opportunity to smaller rooftop owners. o Ownership of individual is well-defined. o Investors reap the direct benefit of electricity and also become energy aware/ efficient. o Investment yields definite returns. o Potential for widespread public deployment. o Successful model globally.  Challenge: o Investment expected from someone who does not understand technology. o Capital subsidies required to incentivize participation (under net-metering scheme). o Direct dealing of DisComs directly with Customers. 21 Distributed Generation- ICORE 2013; 27 Nov

22 Policy Implementation: Preparatory Phase  DisComs: Obvious focal agency o Specify standards of interconnection and Net-Meter. o Set up internal process viz. accepting applications for interconnection, PV system commissioning, regulatory compliance, billing.  State Nodal Agency: GEDA o Empanelment of Channel Partners/ Installers. o Avail necessary funds from State Dept., Central Ministries. o Act as a single-window for disbursing subsidies. o Publicize and monitor overall progress.  Channel Partners/ Installers o Link between System Owners and DisCom/ GEDA for administrative procedures. o Comply with relevant guidelines of safety, standard, performance outlined by DisCom, GEDA, MNRE, GERC, CEA, etc.  Eligible Entities/ System Owners o Only employ Channel Partners/ Installers empanelled by GEDA. o Apply for interconnection of rooftop PV system. o Comply with any other approvals/ clearances required from time to time. o Shall be final beneficiaries of subsidies. o Shall own and be responsible for operation of PV systems. 22 Distributed Generation- ICORE 2013; 27 Nov

23 Policy Implementation: Preparatory Phase 23 GEDA Empanels Channel Partners/ Installers. DisComs set up standards for Net-Metering. GEDA Educates Channel Partners with compliance requirements. GEDA publically promotes Rooftop Solar Policy/Programme DisComs set up internal processes for: 1.Accepting and scrutinizing customer applications, and 2.Commissioning PV systems. DisComs set up internal processes for: 1.Accepting and scrutinizing customer applications, and 2.Commissioning PV systems. Channel Partners commence their own marketing. Rooftop Solar Policy is Launched. Distributed Generation- ICORE 2013; 27 Nov

24 Policy Implementation: Implementation Phase 24 Eligible Entity contacts Channel Partner. Channel Partners undertak- es feasibility of installation. Eligible Entity, via Channel Partner, applies to GEDA for subsidy. GEDA approves: 1.Subsidy subject to fund availability, and 2.PV System capacity subject to DisCom’s and CEI’s clearance. GEDA approves: 1.Subsidy subject to fund availability, and 2.PV System capacity subject to DisCom’s and CEI’s clearance. DisCom: 1.Verifies installation, and 2.Installs Net-Meter to commission the system. DisCom: 1.Verifies installation, and 2.Installs Net-Meter to commission the system. Channel Partner installs rooftop PV system. Eligible Entity, via Channel Partner, applies to DisCom for interconnection. DisCom bills System Owner based on net consumption. System Owner owns and operates the PV system. CEI’s Approves: 1.Capacity of installations CEI’s Approves: 1.Capacity of installations Distributed Generation- ICORE 2013; 27 Nov
