6 Moving Towards grid parity Source:KPMGBy , roof top solar power cost will reach the grid parity.13-Apr-17SOLAR ENERGY CORPORATION OF INDIA
7 Why Rooftop PVOn national level, reduces requirement of land for addition of solar capacitiesFor consumers, itReduces the dependency on grid powerMitigates diesel generator dependencyLong term reliable power sourceFor Discoms, it reducesDay Peak load DemandT&D and conversion losses as power is consumed at the point of generationMost suitable for commercial establishmentsMax generation during peak usage timeSolar power cost is close to the commercial power cost
8 Roof top PV potential in India According to 2011 Census India has:330 million houses166 million electrified houses76 million houses use kerosene for lighting1.08 million houses use solar for lighting140 million houses with proper roof (Concrete or Asbestos / metal sheet)130 million houses having > 2 roomsAverage houses can accommodate 1-3 kWp of solar PV systemLarge commercial roofs can accommodate larger capacitiesAs a conservative estimate, about 25 GW capacity can be accommodated on roofs of buildings having > 2 rooms alone (considering 20% roofs are available/suitable)
9 Rooftop PV Programmes under JNNSM Small scale rooftop PV systemsSize: less than 100 kWpImplemented through MNRE Channel PartnersGenerally in off grid modeLarge scale rooftop PV schemeSize: 100 to 500 kWp grid-connected systems (without battery back up)Implemented through SECI through a process of competitive bidding3 Phases announced; Phase I: 5.5 MW (4 cities); Phase II: 11.3 MW (6 cities); Phase III: 10 MW (9 cities)… more to comePossible locations include public buildings, hospitals, educational institutions, warehouses etc.

12 SECI’s Implementation methodology SECI is implementing the scheme by selected developers through competitive bidding on the project cost in for selected cities .SECI has prepared technical specifications to ensure quality of installations.Under the scheme SECI willAllocate capacity to selected bidders for each city.Verify project proposals w.r.t. technical specifications and release the sanction for subsidy which is linked to performance up to 2 years.Release initial subsidy on successful commissions as per technical specifications. (20%).Release 5 % subsidy at the end of 1st and 2nd year of successful maintenance of the project.Help developers for identification of projects through dissemination workshops and to assist in resolving any issues with concerned authorities.
13 Status of Implementation Phase-I:Chennai – 2 MWBangalore – 2 MWDelhi – 1 MWGurgaon – 0.5 MWCompanies shortlisted as per their bids for each cities against benchmark project cost of Rs. 130/WpProjects allocated up to ~ Rs. 88/WpAbout 4.5 MW of projects already identified and started implementationPhase –II:Revised benchmark cost Rs. 90/WpJaipur – 3.1 MWBhubaneswar/Cuttack - 1 MWHyderabad – 2 MWGurgaon – 1.5 MWNOIDA/ Gr. NOIDA – 1.5 MWRaipur – 2 MWThe initial deadline for identification of the Projects is 14th Nov, 2013
14 Experience in Bhubaneswar 1 MW allotted to two bidders under Phase II of Rooftop schemeFollowing developers selected:M&B Switchgears Ltd (500 kW)Photon Energy (500 kW)About 700 kWp of projects have already been identifiedKalinga Institute of Social Sciences (500 kW)NALCO (160 kW +) - Requested for more capacities on their Angul Plant.Orissa government is also implementing/planning to install roof-top projects on government buildingsMore roof-top capacities could be considered for allocation, if there is good progress and interest of the stake holders
15 Main Issues in implementation Connectivity IssuesElectricity to be fed into grid at Voltage level below 33 KVNo clarity on connectivity norms at these voltagesHowever, CEA has published the CEA (Technical Standards for Connectivity of Distributed Generated Resources), Regulations 2013 recently to address these issuesMetering issuesMany states have no regulations on net meteringNo uniformity of standards, different state regulations inconsistentCEA has come up with draft CEA (Installation and Operation of Meters) Amendment Regulations, 2013SECI working with states to bring out net metering regulations
16 Contd… Business models – Tariff & PPA etc Project Performance Confusion over contract clauses; different tariffs quoted to different consumersSECI has identified some key provisions to be a part of PPA for benefit of rooftop owners and developersSECI may assist in discovering optimum tariff structureProject PerformancePerformance of large scale grid connected rooftops untested in IndiaSECI to monitor performance and facilitate mitigation of issues (if any)

19 Initiatives for promotion of Rooftop PV in Andhra Pradesh AP Solar Policy promoting roof top solar projectsOnly for 3 phase service consumers can setup roof top PV systemsNet metering is allowedRecently announced by a committee that Rs.3.50 per unit would be paid for exported power for 7 yearsThe consumer/SPV generator also has to set up a protection system on their premises with “Islanding” for events like grid failuresAny prevalent subsidy from Government of India can be availed.
20 GujaratGujarat already initiated 5MW Rooftop Project in Gandhi Nagar in PPP model.Generated power is completely fed to the grid.As per their model, Roof owner gets paid lease rent (Rs.3.00 per unit) and the project developer gets feed-in-tariff (Rs.11.21) for 25 years.Recently announced a rooftop scheme for development of 25 MW in 5 other cities.
21 KeralaKerala launched its 10,000 rooftop power plants program forWith each applicant eligible to apply for kW only, the total capacity target is 10 MW.Due to the small per capita limit; the target audience will be only households and small cottage industries.Apart from the MNRE’s 30% capital subsidy, the state is offering a discount of Rs. 39,000 per system.
22 West BengalWest Bengal has initiated a net-metering solar rooftop model promoting self consumption.Under the WBERC Regulations, grid-integrated rooftop PV is allowed only for institutional consumers like government departments, academic institutions, etc.The system size limited to kW, Connectivity is allowed at Low Voltage or Medium Voltage, or 6 KV or 11 KV, of the distribution system of the licensee.Solar injection is permitted only up-to 90% of the annual electricity consumption, and the net energy supplied by the utility would be billed as per existing slab tariffs.Solar generation would first offset consumption in the highest tariff slab and then the lower slab.Policy targets 16 MW of rooftop and small PV installations by 2017.Kolkata development authority mandated all commercial and high raise building to install solar PV to meet 2% of their energy demand.
23 Tamil Nadu Solar Policy 2012 Targets 3000 MW by 2015 , including 350 MW of rooftop capacity in three phases of 100, 125 and 125 MW (per year) during50 MW from domestic customers who will receive a GBI of Rs. 2/kWh for the first two years, Rs. 1/kWh for the next two and Rs. 0.5/kWh for the subsequent two years.300 MW from government buildings and government schemes for rural and urban lighting.Mandates 6% SPO for HT consumers to achieve targets.TEDA designated as single window agency.Connectivity : < 10 kW V< 100 kW – 415 V> 100 kW kV
24 UttarakhandUttarakhand Electricity Regulatory Commission released regulations for solar roof top plants.Allowed roof to projects to connect at the following voltage levels(i) Load up to 4 kW: low voltage single phase supply(ii) Load >4 kW and up to 75 kW: low voltage three phase supply(iii)Load >75 kW and up to 1.5 MW: at 11 kV(iv)Load >1.5 MW and up to 3 MW: at 11/33 kV or as per site condition.UERC determined levelized net tariff for roof top systems as Rs.9.2 without accelerated depreciation and Rs and with accelerated depreciation.
25 Other States/UTChandigarh – Hon’ble Union Minister inaugurated roof top PV projects on July 3, 2013.Punjab and Haryana are vey actively pursuing development of roof top PV projects.Rajasthan expressed to develop 3.1 MW of roof top solar plants in Jaipur.Chhattisgarh is also actively working on roof top programs and submitted request for 2MW.
