Grid connected Rooftop Scheme (Phase I to IV) PAN India: 80 MWp 73 MW Rooftop scheme for Warehouses 50 MWp Rooftop Scheme for CPWD in RESCO mode 500 MWp Rooftop Scheme under 30% Subsidy PAN India 500 MWp Rooftop Scheme without Subsidy Industrial & Commercial Segment
This first-of-its kind Rooftop competitive scheme was launched in Jan 2013 Target Group: Educational Institutes, Hospitals, Government bodies/psus, Commercial Establishments, Industries, Warehouses, Residential Sector etc., Grid connected systems without battery back up Surplus solar power, if any, could be fed to the grid (under netmetering) MNRE provides Central Financial Assistance (CFA) through SECI 30% subsidy is available for schools/colleges, residential sector, Social sector etc. CFA is not available to commercial and industrial sector Incentives/Awards for Government and PSUs#
Achievements so far Rooftop programme expanded from Tier I to Tier III cities: covering 20 States/UTs, over 60 cities Benchmark cost reduced from Rs. 130/Wp to Rs. 75/Wp 120+ MWp capacity allocated among 40 successful bidders covering 20 States including Andaman & Nicobar Islands of India More than 62 MWp (>300 nos. projects) rooftop capacity sanctioned so far 42+ MWp commissioned Rs. 54 Cr CFA released to the project developers (inter-alia means more than Rs. 270 Cr. investment in the rooftop segment).
Advantages of Rooftop Solar PV Social Opportunity for consumer participation and investment Higher employment generation and entrepreneurship options Technical Low distribution losses Last-mile support to grid stability, w.r.t. voltage & reactive power support Creates case for smart grids Administrative Widely accepted, Saves space Lowest time to commission technical and administrative Lower investment in distribution infrastructure (for lower penetrations) Can improve distribution grid capacity 9
Implementation Model Projects are implemented under two broad business models I. CAPEX (Ownership Model) bids invited on project cost II. RESCO (PPA Model) bids invited on tariff Against total 150* MWp rooftop capacity allocated: 70 MWp under Capex Model 52.5 MWp under RESCO 29* MWp ( Ready for allocation)
