Benefits of Grid ConneCted solar rooftop pV

Solar Potential in India

Tropical Country More than 300 sunny days More than 300 sunny days

Around 5000 trillion kwh/year energy incident over India

Potential: 600 GW

Highest global radiation received in Rajasthan & Northern Gujarat

Solar Targets :India

Rooftop solar to account for 40 percent of the target (40 GW)

Residential sector (Grid connected Rooftop PV) :- major part along with large scale utility power plants

Key Benefits for Consumers

Reduces the dependency on grid power, Long term reliable power source Reduction in Utility Electricity Bill; Higher benefits in TOD regime Option for revenue generation through Net Metering Framework One time investment provides 25 years’ solar generation Accelerated Depreciation Benefits for I&C consumers Levelized cost of generation vis-à-vis increasing fossil fuel cost makes economically viable project

Growth Drivers for Residential Consumers

Delhi Solar Policy: Generation Based Incentives (GBI) @ Rs. 2/unit for 3years; applicable to solar plants which generate > 1100 units /KW/annum.

Residential Consumers 30% Capital Subsidy by MNRE Generation Based Incentive (GBI) Net Metering Value creation from unutilized roofs Reduction in Utility Electricity Bill No

Maintenance

Cost

Key Benefits for Discoms Ease of Development (Permits, Site Selection, and Clearances) Minimal operation and maintenance cost Grid Interactive Rooftop Systems Fulfill RPO obligations for Discoms Reduction in T&D losses

• n account of proximity to

load centers Less dependence on fossil fuels-Green source of Energy Low Gestation Period Ease Network Congestion Avoided Network Augmentation Cost

80% Solar Generation Off-sets Normal Hours & 20% Off-sets Peak Hour Load for ToD Consumers

Summer Peak Periods Afternoon - 3pm to 4:30pm Evening – 11pm to 1am Winter Peak Periods Morning- 9am to 11am Evening – 6pm to 8pm

Key Benefits for Discoms: Impact on System Peak Load Peaking of Rooftop Solar Generation is partly co-existent with Peak Demand of Discom

Challenges/Barriers in Large Scale Deployment

• High Upfront Cost
• Apprehensions about the technology
• Limited financing Scheme by Banks
• Shift of I&C consumers to solar result in revenue loss for Discoms
• Issue of Cross subsidy to be handled
• Regulators don’t often factor in / compensate for the cost of the grid

support provided by utility to the solar consumers Technical: Grid-integration challenge with likelihood of ‒ Reversal of power flows across the LT network. ‒ Breach of voltage regulations with tail-end generation feed ‒ Erratic behavior of LV protection systems

Solar Implementation Roadmap for Discoms Identify key markets for solar- Utility can begin offering Commercial & Industrial customers quality and financially attractive rooftop solar systems Standardize and improve quality Streamline the interconnection process for customer Solar Plant Develop standards to ensure quality of solar installations; monitor and track system performance and costs Manage Utility Portfolio: Further develop complementary programs: Demand Side Management /Energy Efficiency, Demand Response to maximize utility value from the solar Manage Supply portfolio: As the installed solar increases, manage the conventional supply portfolio in a complementary manner

• Empanelled as first Utility Channel Partner with Ministry of New & Renewable Energy, GoI
• TPDDL Initiative for providing Value Added Services to consumers on Solar Project received DERC

Approval

• Three Turnkey Solar Project Installation Agencies with Highest Grading have been empanelled
• Association for framing BIS Standard for smart meter(whole current) to be used in Solar Projects.

Smart Net Meter Specification has been finalized

• Received National Award under category “Discom –Promotion /Facilitation for Rooftop Solar “ by

Shri Piyush Goyal, Hon’ble Union Minister for Power, Coal, New and Renewable Energy, GOI

• TPDDL has won the award “Rooftop Solar Enabler of the Year – Utility” under the aegis of the Indian

Rooftop Solar Leadership Awards, 2016

Stakeholder Services Benefit to Customer

TPDDL Empanelment of Implementing Agency with open competitive bidding

• Optimum price with superior technology
• Benefit of Economy of Scale

Consumer Benefits from TPDDL Solar Projects

Tie Up with Indian Bank

• Proposal received from the Indian Bank offering attractive interest rates for TPDDL

consumers :-  For individuals, SHGs, NGOs etc.: 10.75 %  For Industrial & Commercial Consumers: 10.25 %  Home loan for consumers installing Rooftop Solar PVs : 9.55% (upto Rs. 75 lakhs) 9.75% (>Rs. 75 lakhs)

• Joint Marketing Plan

 Subsequently, we would be carrying out joint promotional campaign for the potential target

• consumers. Following plan has been chalked out :-

 Joint visits to potential consumers  Presentations to be delivered during IWA and RWA meets for consumer sensitization  Display about the offer from banks on TPDDL websites  E-Mailers to be sent to the registered consumer base  Leaflets highlighting about the tie-up and scheme to be sent along with the electricity bills

• Total 82 cases with cumulative solar capacity of 5.6 MWp are connected

with Tata Power Delhi Distribution Grid/ under progress for connection.

• TPDDL till date has set up 15 Grid Connected Solar Plants, with a cumulative

capacity of 1.78 MW, in its own premises.

• 40 Awareness Campaigns done covering 1200 nos. of Potential consumers.
• Proposals under consideration by Consumers – 59 cases with 3.2 MW

SOLAR PROJECT STATUS

16 Camps at various RWAs Camps at various IWAs Camps at various IWAs

• More than 1000 Industrialists &

Domestic consumers participated

• Presentations have been made to

Key Consumers like DJB, DMRC and NDMC.
