The document examines the implementation of solar irrigation in three Indian states, focusing on the water-energy-food (WEF) nexus. It analyzes the effectiveness of standalone and grid-connected solar pumps, the role of the PM-KUSUM scheme, and the challenges of financing, coordination, and groundwater management. Key findings highlight the success of combining solar pumps with micro-irrigation in Rajasthan, the innovative cooperative and IoT monitoring models in Gujarat, and the use of BLDC pumps and grid-scale solar planning in Andhra Pradesh.

The case study examines the Solar Pump Irrigators’ Cooperatives Enterprise (SPICE) in Dhundi, Gujarat, which uses solar pumps to provide irrigation and sell excess electricity to the grid. This model has increased farmer incomes, reduced water costs for buyers, and lowered carbon emissions by replacing diesel pumps. Key success factors include a 25-year power purchase agreement with the local utility, MGVCL, and a financial structure combining farmer contributions with research grants. The project demonstrates that solar power can act as a 'cash crop' for farmers, provided incentives exist to prevent groundwater over-exploitation.
