Scaling Rural Distributed Renewable Energy in India

This report by the International Institute for Sustainable Development (IISD) and Idam Infrastructure Advisory Pvt. Ltd. proposes a system-level framework for planning and implementing distributed renewable energy (DRE) in rural India. Moving beyond fragmented, scheme-driven installations, the study advocates for a 'Model DRE Village' approach that integrates load typology analysis, utility-led planning, and coordinated financing to improve rural electricity reliability and support India's 500 GW non-fossil capacity target by 2030.

• Rural DRE success often depends on individual champions and informal arrangements, making it fragile. Durable deployment requires formalized institutional roles, accountability mechanisms, and structured operation and maintenance (O&M) processes.
• Load typology—the dominant composition and time pattern of electricity demand—is the primary driver for DRE system design. Agriculture-heavy villages should prioritize solarizing agricultural power for daytime consumption, while evening-peaking villages require integrated storage and grid interaction solutions.
• Scaling DRE can create surplus generation and reverse power flows that stress local networks, particularly in seasonal agricultural settings. While village-level storage can reduce peak imports, storage at higher network levels (such as substations) can better pool diverse loads and improve utilization.
• The report proposes a 'Village Energy Plan' (VEP) as a single planning instrument to align various existing DRE schemes. This plan would consolidate typology, load assessment, demand projections, system configuration, techno-economic results, financing convergence, and implementation roles.
• Regulatory alignment, specifically regarding metering and compensation, determines the scalability of DRE. For example, virtual net metering (VNM) is limited to apartments and housing societies in Maharashtra, whereas Assam allows wider residential use, making aggregation models more feasible in Assam.
• Techno-economic modelling in Hiware Bazar (Maharashtra) showed that a 980 kW ground-mounted solar system yielded an LCOE of INR 3.06/kWh with subsidy (INR 4.09/kWh without), both below the state APPC of INR 5.78/kWh. Adding a 350 kW/1,400 kWh battery energy storage system (BESS) raised the blended LCOE to INR 5.44/kWh (with subsidy), which remains comparable to the APPC.
• In Bamun Sualkuchi (Assam), a 1,318 kW on-grid configuration (70% ground-mounted, 30% rooftop) had an estimated LCOE of INR 4.03/kWh with subsidy (INR 6.01/kWh without), well below the state APPC of INR 8.46/kWh. A 500 kW/2,000 kWh BESS raised the blended cost above APPC, but a smaller 400 kW/1,600 kWh BESS kept costs below APPC (INR 8.27/kWh with subsidy).
• The proposed Model DRE Village Framework emphasizes a co-implementation model where distribution companies (DISCOMs) anchor technical planning, grid integration, and asset ownership, while Gram Panchayats and village energy committees (VECs) manage community mobilization, demand identification, and local governance.
• Existing flagship schemes like PMSGMBY and PM-KUSUM face structural challenges, including a mismatch between registrations and actual installations, socio-economic skew in adoption due to high upfront costs, and a lack of motivation for adoption in states providing free electricity.
