Department of Power Government of NCT of Delhi Delhi Solar Policy

Solar Potential of Delhi Solar Potential by Sector • Rooftop Solar potential in Delhi – 2.5 GW estimated potential for Rooftop Solar 26 • Government – 26% 49 • Commercial, industrial – 25% 25 • Residential – 49% • Current installed solar capacity is 12 MWp and 15 MWp is under implementation. • Financing potential and options in Delhi are well above average • Discom networks relatively better than elsewhere in India (low loss/theft) • Very little grid downtime, ideal for solar installations without batteries (“the grid is the storage”) • With the right solar policy and implementation, Delhi can reach 1 GW Solar Power capacity in 5 years 2

Delhi can become a shining example for rooftop solar in India! • Remember Delhi’s CNG revolution a decade ago? • Delhi has the opportunity to lead a rooftop solar revolution! • 400 MW on Delhi govt. rooftops can save ~ 200 crores/year – In 20 years, Delhi government can save over 5,100 crores! • Delhi can cut its electricity expense, improve energy security, and shave off over 10% of peak demand by 2025, reducing the need for new PPAs! * Savings for 1 MW with INR 3.5/unit gap = INR 51 lakhs/year; with 0.5% annual output reduction; 5% CAGR in conventional 3 power.

Rooftop Solar Economics in Delhi • 1 kW Solar System Parameters – Cost ~ INR 65,000 Includes panels, inverter, installation – Rooftop space needed ~ 10 sq. meters (3m x 3.3m) – Generates ~ 1,300 kWh (units)/year – Households generate electricity worth INR 11.5K/year • Payback time 6 - 7 years* – Commercial/Industrial/government generate electricity worth INR 15K/year • Payback time ~5 years* • After payback, rooftop earnings are pure profit for the next 18-20 years • Tariff – and payback time – vary by consumption. Household calculation is for • the 400-800 units/month band. 4

Initiatives taken by EE & REM Centre • Promotion of LED in all buildings, street lightings and hoardings, advertisements etc. 45 lac LED bulbs have been distributed and 1.62 lac street lights have been changed in Delhi from conventional to solar. • Mandatory use of Solar Water Heaters in Delhi in different categories of buildings. Delhi Govt has also provided subsidy of Rs. 6000/- for domestic Solar Water Heating Systems & up to Rs 6000/- (@ Rs. 6000/- per 100 LPD) for Systems installed in Non-commercial Institutions/organizations. • Mandatory use of ISI marked Motor pump sets, Power capacitor, and foot/Reflex valves in Agriculture Sector of Delhi State. • It is proposed to make Delhi Secretariat the first Green, Energy Efficient secretariat operating completely on Solar Energy. For this a 3MWp surface mounted SPV plant is being installed on the vacant land of erstwhile Indraprastha Power Station. Power generated from this 3MWp SPV plant will be dedicated to Delhi Secretariat for meeting out the total electricity requirement of the building. • Out of total capacity of 3MWp SPV plant, 1 MWp capacity has already been commissioned on 24.10.2015 and the power generated is being used in Delhi Secretariat. This is resulting in saving of approx Rs 6 Lacs per month which shall increase to 18 lac per month.

Initiatives taken by EE & REM Centre • EE&REM Centre under Department of Power, participated in the Indian International Trade Fair 2015 held at Pragati Maidan, Delhi. The theme was Renewable Energy. Quizzes were organized daily for the general public to create awareness about rooftop Solar PV Power Plant, Net Metering benefit and Frequently Asked Questions and the prizes to the successful participants were given. • A series of workshops are being conducted to disseminate the knowledge about Renewable Energy, Energy Efficiency and Energy conservation among the citizens of Delhi through Resident Welfare Associations. Reputed experts from Bureau of Energy Efficiency (BEE), Energy Efficiency Service Limited (EESL), National Productivity Council (NPC), Indian Institute of Technology, Delhi and EE&REM informed about the importance of Renewable Energy, Energy efficiency & conservation and how to achieve it using simple tips in domestic sector like houses, shops, parks etc. • Organising “ Suryamitra ” training programs in Delhi state in collaboration with National Institute of Solar Energy (NISE) and The Energy Resources Institute (TERI). • Provided active support and cooperation to the National Campaign of Bureau of Energy Efficiency on Energy Conservation i.e. “Painting Competition on Energy Conservation” since 2007, to spread the message of energy conservation among the younger generation.

Delhi Solar Policy

Highlights of the policy • Achieve aggressive yet realistic rooftop solar growth in Delhi – 1.0 GW by 2020 (14% of peak load, 4% of total energy) – 2.0 GW by 2025 (21% of peak load, 7% of total energy) • Zero subsidies from Delhi government • Use market-based approaches and regulations to drive growth – Support all business models: Self-owned or third-party-owned – Promote soft loans, such as from central agencies (IREDA, REC, PFC) and/or solar sector soft loans from SBI, World Bank, KfW, etc. • Ensure fairness for all stakeholders in the solar ecosystem – Rooftop owners in all consumer segments, Discoms, investors, technology and services providers, non-rooftop solar and non-solar power consumers & manufacturers.

Net Metering PV Modules Solar Meter Net Meter Consumer’s Premises Distribution Transformer GRID

Hybrid Net-Metering With Battery Backup PV Modules - Separate AC Solar Energy Meter might not be possible. - Alternatively: Solar Energy Generated =Consump. M. – Net M. Net Meter Consumption PCU Meter Consumer’s Premises Distribution Transformer GRID "Considerations in Rooftop Solar Installations," SESI iCon, 29 Jan. 2016, New 10 Delhi.

Delhi Solar Policy Highlights Drive Net Metering Adoption • Promote net metering for every solar installation at or above 1 kW • Self-consume first . Allow up to sanctioned load to be fed into grid • Parity pricing for exported energy • Monthly credits on exported energy. At year end, discom will pay for surplus solar energy at average power purchase cost • Discom responsible for reading/reporting gen, self-consumption, and export – All net metered solar energy generated will count towards discom’s solar RPO • Discoms to streamline net metering, put all requests online with status 11

Delhi Solar Policy Highlights Drive Net Metering Adoption Group Net Metering • Treat two connections as one for energy accounting purposes • Encourages fuller realization of rooftop potential – solves problem of large rooftop/low consumption • But only if same consumer name, in single discom area • Initially case-by-case approval by DERC. • A joint committee comprising of members from DERC, the state power department, SNA shall be formed to achieve this policy objective. 12

Delhi Solar Policy Highlights Drive Net Metering Adoption Virtual Net Metering • To give access to the solar net metering facility for consumers who do not have a suitable space in its premises/rooftop for installing a solar system (e.g. residential consumers who live in apartments, consumers with shaded rooftops) • In Virtual Net Metering consumers can be beneficial owners of a part of a collectively owned solar system. • All energy produced by a collectively owned solar system will be fed into the grid through an energy meter and the exported energy as recorded by that meter will be pro rata credited in the electricity bill of each participating consumer on the basis of beneficial ownership. • A joint committee comprising of members from DERC, the state power department, SNA shall be formed to achieve this policy objective.

Delhi Solar Policy Highlights Generation Based Incentive (GBI) • Solar hasn’t yet achieved grid parity for low -mid range of domestic users • Variable domestic tariff structure (above fixed charge of INR 100 p.m.): Units 0-200 201-400 401-800 801-1200 1200+ Tariff (INR) 4 5.95 7.30 8.10 8.75 • A limited-time incentive will reduce payback time and increase adoption • Generation Based Incentive for 3 years • The minimum eligibility criteria for GBI has also been prescribed at 1000 units (kWh) per annum per kW and shall be capped at 1500 kWh per kWp. • INR 2/solar unit generated – Will reduce payback time by 1-2 years 30.0 New GBI 25.0 – But no subsidy benefit of lower slab 20.0 • Total GBI Maximum cost to state will be small vs. 15.0 its impact 10.0 – 50 crores over 3 years on first come 5.0 first serve basis 0.0 2015-16 2016-17 2017-18 2018-19 2019-20 14

Delhi Solar Policy Highlights A Green Fund Leverage existing Air Ambience Fund in Delhi that’s funded by a cess on diesel • Payment of Generation Based Incentive (GBI) – This amounts to about 38 crores over 3 years • Drive Public Awareness of solar energy and its benefits • Education – technical training / certification programs for solar skill development; this will help create new jobs in Delhi 15
