PM KUSUM-B: Karnataka saves ₹200 crore annually after installation of 27,700 solar-powered pump sets
These pump sets are also expected to prevent the purchase of 240 million units of electricity every year, resulting in annual power purchase savings of about ₹146 crore for Escoms.

Context
Karnataka’s Energy Department reported significant progress under Component B of the scheme, with over 27,700 standalone solar-powered agricultural pump sets installed. This has resulted in annual savings of ₹200 crore in agricultural electricity subsidies and reduced grid demand by nearly 144 MW. The overwhelming response of over one lakh farmer applications highlights the growing adoption of decentralized renewable energy in agriculture, contributing to energy security and reduced power purchase costs for the state's electricity supply companies.
UPSC Perspectives
Economic
The economic impact of the scheme in Karnataka demonstrates a successful model for reducing state fiscal burdens. Historically, agricultural electricity subsidies have placed immense strain on state exchequers and State Electricity Distribution Companies (DISCOMs). By shifting farmers to standalone solar pumps, the state directly reduces its subsidy burden, saving an estimated ₹200 crore annually. Furthermore, this transition curtails the demand for conventional grid power by 144 MW, preventing the purchase of 240 million units of electricity. This results in significant power purchase savings for DISCOMs, improving their financial health and operational efficiency. The funding model—50% state subsidy, 30% central assistance, and a 20% farmer contribution—illustrates cooperative federalism in financing energy transitions, making clean technology accessible to the agricultural sector while mitigating state expenditure.
Environmental
The transition to solar-powered irrigation under Component B is a crucial step towards sustainable agriculture and achieving India's climate goals. The agricultural sector is a significant consumer of groundwater and electricity, often relying on fossil fuel-dominated grid power or highly polluting diesel pumps. The deployment of standalone solar pumps promotes decentralized renewable energy, directly reducing the carbon footprint of farming operations. By decreasing reliance on grid electricity, the state avoids the greenhouse gas emissions associated with conventional power generation. However, a potential environmental concern that UPSC candidates must consider is the risk of groundwater over-exploitation. Since solar energy is effectively 'free' once installed, farmers might be incentivized to pump water excessively, leading to rapid depletion of aquifers, a challenge that requires parallel water management strategies.
Governance
The successful implementation of in Karnataka underscores the importance of effective governance and addressing administrative bottlenecks in rolling out national schemes. The Energy Department's focus on simplifying processes and resolving implementation issues was critical in gaining the trust of farmers, as evidenced by the receipt of over one lakh applications. This highlights the concept of ease of doing business at the grassroots level. The scheme represents a transformative shift from merely providing subsidized electricity to investing in energy security and rural infrastructure. It empowers farmers by making them energy-independent, improving their quality of life, and reducing vulnerability to power cuts. For UPSC Mains, this serves as a robust case study on how targeted government interventions, backed by substantial subsidies and streamlined administration, can drive behavioral change towards sustainable practices in the agricultural sector.
