6 Moving Towards grid parity
Source:KPMG By , roof top solar power cost will reach the grid parity. 13-Apr-17 SOLAR ENERGY CORPORATION OF INDIA

7 Why Rooftop PV On national level, reduces requirement of land for addition of solar capacities For consumers, it Reduces the dependency on grid power Mitigates diesel generator dependency Long term reliable power source For Discoms, it reduces Day Peak load Demand T&D and conversion losses as power is consumed at the point of generation Most suitable for commercial establishments Max generation during peak usage time Solar power cost is close to the commercial power cost

8 Roof top PV potential in India
According to 2011 Census India has: 330 million houses 166 million electrified houses 76 million houses use kerosene for lighting 1.08 million houses use solar for lighting 140 million houses with proper roof (Concrete or Asbestos / metal sheet) 130 million houses having > 2 rooms Average houses can accommodate 1-3 kWp of solar PV system Large commercial roofs can accommodate larger capacities As 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 systems Size: less than 100 kWp Implemented through MNRE Channel Partners Generally in off grid mode Large scale rooftop PV scheme Size: 100 to 500 kWp grid-connected systems (without battery back up) Implemented through SECI through a process of competitive bidding 3 Phases announced; Phase I: 5.5 MW (4 cities); Phase II: 11.3 MW (6 cities); Phase III: 10 MW (9 cities)… more to come Possible locations include public buildings, hospitals, educational institutions, warehouses etc.

MNRE’s Large-scale Rooftop PV Scheme 30% subsidy available from MNRE Projects being set up in select cities Project capacity: Phase I: under implementation Phase II: Rooftop identification in progress Phase III: Projects in bidding and evaluation stage Chandigarh (1) Noida/Greater Noida (1.5) Gurgaon (2) New Delhi (2) Jaipur (3.25) Palatana (1) Gwalior (1) Kolkata (1) Bhubaneswar (1) Mumbai (1) Raipur (2.05) Pune (1) Legend Phase I Phase II Phase III Multiple phases Capacity in MW () Hyderabad (2) Bangalore (2) Chennai (4) Coimbatore (1) 13-Apr-17 SOLAR ENERGY CORPORATION OF INDIA 11

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 will Allocate 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 MW Bangalore – 2 MW Delhi – 1 MW Gurgaon – 0.5 MW Companies shortlisted as per their bids for each cities against benchmark project cost of Rs. 130/Wp Projects allocated up to ~ Rs. 88/Wp About 4.5 MW of projects already identified and started implementation Phase –II: Revised benchmark cost Rs. 90/Wp Jaipur – 3.1 MW Bhubaneswar/Cuttack - 1 MW Hyderabad – 2 MW Gurgaon – 1.5 MW NOIDA/ Gr. NOIDA – 1.5 MW Raipur – 2 MW The 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 scheme Following developers selected: M&B Switchgears Ltd (500 kW) Photon Energy (500 kW) About 700 kWp of projects have already been identified Kalinga 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 buildings More 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 Issues Electricity to be fed into grid at Voltage level below 33 KV No clarity on connectivity norms at these voltages However, CEA has published the CEA (Technical Standards for Connectivity of Distributed Generated Resources), Regulations 2013 recently to address these issues Metering issues Many states have no regulations on net metering No uniformity of standards, different state regulations inconsistent CEA has come up with draft CEA (Installation and Operation of Meters) Amendment Regulations, 2013 SECI 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 consumers SECI has identified some key provisions to be a part of PPA for benefit of rooftop owners and developers SECI may assist in discovering optimum tariff structure Project Performance Performance of large scale grid connected rooftops untested in India SECI to monitor performance and facilitate mitigation of issues (if any)

18 States’ Initiatives for Rooftop PV

19 Initiatives for promotion of Rooftop PV in Andhra Pradesh
AP Solar Policy promoting roof top solar projects Only for 3 phase service consumers can setup roof top PV systems Net metering is allowed Recently announced by a committee that Rs.3.50 per unit would be paid for exported power for 7 years The consumer/SPV generator also has to set up a protection system on their premises with “Islanding” for events like grid failures Any prevalent subsidy from Government of India can be availed.

20 Gujarat Gujarat 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 Kerala Kerala launched its 10,000 rooftop power plants program for With 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 Bengal West 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) during 50 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 Uttarakhand Uttarakhand 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/UT Chandigarh – 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.
