Tariff Analysis and Cost-Benefit Tool for Solarizing Irrigation

The Tariff Analysis and Cost-Benefit Tool for Solarizing Irrigation (TACTS) is an Excel-based tool created to support the implementation of solarized irrigation in India, specifically under the PM-KUSUM scheme. It addresses barriers such as unviable tariffs, financing difficulties, and lack of administrative buy-in by providing sections for tariff calculation, financing projections, and cost-benefit quantification. The tool emphasizes that grid unavailability significantly affects the levelized cost of energy and argues that solarizing agricultural power can reduce greenhouse gas emissions and state subsidy obligations.

• The TACTS tool is designed to address three primary barriers to the solarization of irrigation power in India: the lack of administrative buy-in, unviable tariffs set by state regulators, and challenges in project financing.
• Solarizing agricultural power demand, particularly for irrigation, offers multiple benefits including improved energy access, lower greenhouse gas emissions, more cost-effective renewable energy integration, and a reduction in power procurement costs and state subsidy obligations.
• Grid unavailability is a critical factor that impacts the levelized cost of energy tariff, necessitating proper exercise of unavailability clauses and appropriate compensation for solar developers for lost generation.
• The PM-KUSUM scheme, launched by the Government of India in 2019, includes components A and C-FLS that provide incentives for installing medium-scale distributed solar power plants (between 1 and 10 MW) connected to distribution substations to meet agricultural power needs.
