Suppose a borewell-dependent farmer receives subsidised electricity. Lower direct pumping cost may help maintain production in a dry year, but groundwater is a common resource. If pumping exceeds recharge, falling water tables raise future energy and well costs for neighbours. Metering, feeder reliability, crop choice and water-saving equipment influence whether the policy remains affordable and environmentally sustainable.

For the public budget, a subsidy can appear as compensation to a power utility rather than as cash to the farmer. The utility still needs to pay for purchased power, network upkeep and employees. If promised compensation is delayed, arrears can move the pressure into utility finances. A cost-benefit discussion must therefore include the farmer, the aquifer, the distribution company and the treasury.

Exam application: identify an energy subsidy as a fiscal flow, not a generation asset. Explain why a free tariff does not imply zero resource cost.

Worked example: If a farm-power subsidy is budgeted, trace four actors: state government, distribution utility, farmer and electricity supplier. The farmer's bill may be reduced, but the utility still incurs a supply cost and needs reimbursement. A stated allocation does not prove that all arrears are cleared or feeders are reliable. Separate fiscal provision, tariff policy, physical delivery and farm output when deciding whether the support achieved its purpose.
