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 30% Capital Subsidy by MNRE Delhi Solar Policy: Generation Generation No Based Incentives (GBI) @ Rs. 2/unit Based Maintenance for 3years; applicable to solar Incentive Cost plants which generate > 1100 units (GBI) /KW/annum . Residential Consumers Reduction in Utility Net Electricity Metering Bill Value creation from unutilized roofs
Key Benefits for Discoms Avoided Network Augmentation Cost Ease of Development Minimal operation and (Permits, Site Selection, maintenance cost and Clearances) Fulfill RPO obligations for Grid Interactive Low Gestation Period Discoms Rooftop Systems Reduction in T&D losses on account of proximity to Ease Network Congestion load centers Less dependence on fossil fuels-Green source of Energy
9 Key Benefits for Discoms: Impact on System Peak Load 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 9 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 11 Manage Supply portfolio: As the installed solar increases, manage the conventional supply portfolio in a complementary manner
