Implementing Solar Irrigation Sustainably

The document outlines a framework for the sustainable deployment of solar irrigation in India, focusing on the water-energy-food (WEF) nexus. It provides detailed guidance across five key areas: inter-departmental coordination, financing and affordability, beneficiary targeting, infrastructure support, and monitoring and evaluation (M&E). The guide emphasizes the need to protect groundwater resources, support small and marginal farmers, and transition away from high-subsidy models through innovative financing and ownership structures.

• Sustainable implementation of solar irrigation requires horizontal coordination between at least six state agencies, including renewable energy development agencies, agriculture and horticulture departments, DISCOMs, water resources departments, rural development departments, and finance departments.
• To address the high upfront capital costs of solar pumps, states should move away from a 'high subsidy' model by using bulk procurement to achieve economies of scale, establishing loan default guarantee funds to reduce bank risk, and providing interest subventions.
• Alternative ownership models can increase accessibility for low-income farmers; these include community-ownership (shared by collectives), entrepreneurship models (village-level entrepreneurs selling water), and irrigation-as-a-service models.
• Effective targeting is necessary to prevent groundwater depletion and ensure equity. Standalone pumps should be prioritized in areas with poor grid access and adequate water, while grid-connected pumps should be targeted where electric pump usage is high.
• To ensure social equity, eligibility rules should be relaxed to allow tenant farmers and women to participate, and a specific quota of pumps should be reserved for small and marginal farmers.
• Water use efficiency can be improved by bundling solar pumps with micro-irrigation technologies like drip and sprinkler systems, and by leveraging surface water sources to reduce groundwater pressure.
• For grid-connected pumps, states should deploy smart meters and bidirectional metering to enable farmers to become 'prosumers' who sell excess electricity back to the grid, thereby increasing their income.
• The use of 'watchdog transformers' with smart meters can address the 'free-rider' challenge in grid-connected schemes by monitoring and remotely disconnecting non-participating farmers who overdraw electricity.
• Monitoring and evaluation (M&E) should utilize Solar Energy Data Management (SEDM) platforms for technical data, but must be supplemented by representative farmer surveys and groundwater assessments to capture social and environmental impacts.
