Scaling Rural Distributed Renewable Energy in India

The report argues that India's rural electrification must shift from simple access to improving reliability and quality through distributed renewable energy (DRE). While centralized projects are essential for national targets, DRE can address last-mile constraints. The authors develop a 'Model DRE Village Framework' that uses load typologies—such as agriculture-dominant versus residential-dominant—to determine system sizing, storage needs, and grid integration. Through techno-economic modelling in Hiware Bazar (Maharashtra) and Bamun Sualkuchi (Assam), the study demonstrates that solarization is generally cost-competitive compared to average power purchase costs (APPC), though battery energy storage systems (BESS) require careful sizing to remain affordable. The framework emphasizes a co-implementation model where distribution companies (DISCOMs) lead technical planning and ownership, while Gram Panchayats manage community governance and onboarding.

• In agriculture-heavy villages, solar generation often exceeds local consumption during non-irrigation months, creating surplus injections and reverse power flows that stress local networks.
• Techno-economic modelling in Hiware Bazar shows that a 980 kW ground-mounted solar system is cost-competitive, with an LCOE of INR 3.06/kWh (with subsidy), which is below the state APPC of INR 5.78/kWh.
• In Bamun Sualkuchi, a 1,318 kW on-grid configuration (70% ground-mounted, 30% rooftop) is cost-competitive with an LCOE of INR 4.03/kWh (with subsidy), compared to the state APPC of INR 8.46/kWh.
• Battery energy storage systems (BESS) increase the blended LCOE and may exceed the APPC if oversized; for example, a 500 kW/2,000 kWh BESS in Bamun Sualkuchi raised the LCOE to INR 9.75/kWh, exceeding the APPC of INR 8.46/kWh.
• Regulatory differences between states impact scalability; for instance, Maharashtra limits virtual net metering (VNM) to apartments and housing societies, while Assam allows wider residential use, facilitating shared solar assets.
• The framework suggests a multi-tiered governance structure where DISCOMs act as technical anchors and owners, while Gram Panchayats and Village Energy Committees (VECs) handle community mobilization and monitoring.
