Application/Intent Form, Registration Form, Checklist, SLD, Commissioning Certi cate, Consumer Agreement Background The GoI has launched an ambitious rooftop target of 40GW by 2022 to promote renewable energy for addressing India's energy security challenges. The target is part of India's commitment before United Nations Framework Convention on Climate Change (UNFCCC). As consequence of this initiative, MNRE has laid down tentative renewable energy target for each state. Delhi is well positioned to lead India's rooftop solar revolution and has consequently established solar generation targets of 1GW (1000 MW) by 2020 (4.2% of energy consumed) and 2.0 GW (2000 MW) by 2025 (6.6% of energy consumed).. The Government of NCT of Delhi (GNCTD) recognizes this intent, and has laid down the foundation for effective compliance and rapid capacity addition of renewable energy in its territory. Among the various renewable energy options available, ground mounted renewable energy systems are unfeasible in Delhi's densely populated areas. This is due to scare availability of contiguous land parcels. However, due to high degree of development and urbanization in Delhi area, solar rooftop PV is considered to be most appropriate and viable. By this way, solar rooftop holds a promising future with the potential of lowering the state's expenditure on energy, strengthening its energy security, and reducing its reliance on unsustainable fossil fuels. The Department of Power, GNCTD, has nominated Indraprastha Power Generation Co. Ltd (). as a nodal agency for tendering and installation of solar power systems across the city for the various departments of GNCTD/autonomous bodies. Introduction BRPL rooftop program is a utility anchored rooftop program in residential sector being hosted by a power distribution company in India. Through this program, BRPL plans to create a platform to catalogue and aggregate all interested rooftop consumers in its distribution jurisdiction, starting with single point delivery consumers in Dwarka and the solar rooftop vendors / integrators who are empanelled by, GoNCTD / SECI/MNRE. The program is proposed to be run in line with DERC Net Metering Regulations 2014 and guided by Delhi Solar Policy 2016 aiming to maximize utilization solar rooftop potential in Delhi. The program is to be launched under the alias of BRPL Solar City Initiative. The aim of the program is to accelerate rooftop development within utility jurisdiction by aggregating consumers and bringing in the necessary participation from solar rooftop developers through creation of a platform. The program also aims at educating consumer of bene t of solar energy while ensuring strict quality compliance of the systems being set up. To start with in the intial phase BRPL is targeting Community Group Housing Society consumers to bring the bene t of rooftop to societies in Dwarka, in-line with the DERC Net Metering Regulation The program is to be launched under the alias of BRPL Solar City Initiative (of which rst event s named as SOLARIZE DWARKA). This process is to supplement Govt. of Delhi efforts of accelerating rooftop development in Delhi area.

10 SOLAR PHOTO-VOLTAIC (PV) ROOFTOP FREQUENTLY ASKED QUESTIONS (FAQ'S) 1. What is a Solar Rooftop System? In a solar rooftop system, the solar panels are installed in the roof of any residential, commercial, institutional and industrial buildings. This can be of two types (i) Solar Rooftop System with storage facility using battery, and (ii) Grid Connected Solar Rooftop System. 2. What is a Grid Connected Solar Rooftop System? In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to the grid either of 33 kv/11 kv three phase lines or of 440/220 Volt three/single phase line depending on the capacity of the system installed at institution/commercial establishment or residential complex and the regulatory framework speci ed for respective States. These systems generate power during the day time which is utilized fully by powering captive loads and feed excess power to the grid as long as grid is available. In case, where solar power is not suf cient due to cloud cover etc., the captive loads are served by drawing power from the grid. 3. Where such plants can be installed? Such rooftop systems can be installed at the roofs of residential and commercial complex, housing societies, community centers, government organizations, private institutions etc. 4. How can I install the grid connected solar rooftop plant (types of business models)? Solar PV rooftop can be installed through two prevalent business models: RESCO and CAPEX. - RESCO: No upfront investment required for installation of solar plant in RESCO model. In this model the rooftop system is owned by a third party or a project developer. The project developer can sell the solar energy directly to the roof owner or any other captive consumer or the distribution company, under a Power Purchase Agreement. The PPA, contractually binds the developer and the consumer on a mutually agreed per-kwh tariff for a xed time period. - CAPEX: Consumers invests all the necessary capital for the project. In this model, the rooftop owner, who can be a commercial, industrial or a residential consumer, hires a system integrator/epc company to install the rooftop SPV system by putting in all the necessary investment. The system is owned by the roof owner, who is responsible for O&M of the plant for the lifetime of the project. The roof owner, generally enters into an annual maintenance contract with the system integrator, under which the system owner can make service requests to system integrator/epc company regarding system performance and maintenance. 5. What is Net-Metering? Net metering is a billing mechanism provided by the utility, that offsets utility billed units with those generated through Renewable Energy system like Solar rooftop projects. Grid acts as storage.excess Solar Generation to be exported to grid relatively. 6. How much energy does a 1 kw solar plant generate? Under the environmental conditions prevalent in Delhi and NCR areas, a 1 kw system generates 120 units of electricity per month. 7. What kind of system will be in Group Housing Society (GHS)? A solar rooftop project in CGHS consumer category serves a unique and an interesting case. With several common rooftops available in a society, there is a great potential for harnessing solar energy through rooftop PV systems. The energy generated from these systems is used to offset the common loads of the society (common lighting, lift, pumps, etc.). In the society ultimately gets bene ted in terms of reduced monthly electricity maintenance cost. Net Metered Solar PV installation shall be provided against, the Single Point Delivery (SPD) common meter of Cooperative Group Housing Society (CGHS).

11 8. What is BRPL Solar City Initiative? BRPL Solar City Initiative is one of a kind solar rooftop program being promoted BRPL.. The aim of the program is to accelerate rooftop development within utility jurisdiction by aggregating consumers and bringing in the necessary participation from solar rooftop developers. The program also aims at educating consumer of bene t of solar energy while ensuring strict quality compliance of the systems being set up. 9. Who will own the system in GHS? The RWA of the respective society shall be the owner of the solar rooftop project. 10. What will be cost of system? The cost of the system shall be determined by negotiations between developers and consumers directly. However, listed vendors costs shall serve as a benchmark for negotiations. (URL: What will be nancial assistance provided? Financial assistance provided, will be in terms of 30 % capital subsidy provided by the MNRE along with Rs. 2 Generation based Incentive allotted to a limited number of early projects by Govt of Delhi This nancial assistance is proposed to be withdrawn for >5 residential installation. (URL: lemanager/userfiles/comments-on_rts.pdf) 12. Will the system offset my electricity bills? The system shall offset common electricity consumption units of the group housing society. 13. What will be potential size of the system? The size of the system shall be limited by shadow free roof space available at premises along with common connected load of the society. 14. How much rooftop area is required for grid connected rooftop project? As a standard, 1 kw rooftop PV project requires approx.12 sq.m. 15. What happens in case of grid failure? As these are net metered projects/grid tied projects, with the failure of grid power, the rooftop system too shall stop operating. However, with the help of batteries/storage systems, these systems can remain operation during grid failure. 16. What is the role of BRPL? BRPL shall act as a facilitator in aggregating the consumers and matching the demand with the project developer supply. In the process, BRPL shall ensure strict technical compliance of the revised technical speci cation from all the project developers. BRPL shall also ensure, plant monitoring of all potential upcoming projects set up in its operating area. 17. How do I know which vendor to select? BRPL has provided with revised technical speci cation to all vendors. BRPL shall make available the list of complying vendors to all consumers to choose from. Consumers are free to negotiate rates mutually with the vendors. 18. How much savings/bene t can I envisage? A 1 kw system generally corresponds to average monthly savings of INR 750 for a period of 25 years on electricity bills and Generation Based Incentive (GBI) of INR 250 for a limited period of 3 yrs. on rst cum rst serve basis.
