When a farmer uses conventional electricity, he pays a subsidised tariff and so will be careful about wasting power. Since solar pumps have no billing, he will tend to leave his pump on, draining more of precious ground water.
“I propose to expand the scheme to provide 20 lakh farmers for setting up stand‐alone solar pumps; further we shall also help another 15 lakh farmers solarise their grid‐connected pump sets. In addition, a scheme to enable farmers to set up solar power generation capacity on their fallow/barren lands and to sell it to the grid would be operationalized."
The above proposal was made by Finance Minister Nirmala Sitharaman as part of her Budget speech this morning. The proposal sounds good. Even sensible. But it could turn out to be a nasty proposal. For two reasons:
First, when a farmer uses conventional electricity, he pays a subsidised tariff (of around Re 1 per kWh or thereabout). That makes him careful about not wasting electricity and thus pushing up his bills. He thus uses less groundwater. When he has a solar pump, there is no billing. So he will tend to leave his pump on, draining more of precious groundwater. This is disastrous, especially for a country that is already witnessing declining water tables.
The other alternative is to persuade him to sell surplus solar power back to the grid and thus earn some money. That will probably persuade him to switch off his pump and send the solar power to the grid and earn a feed-in tariff from the state electricity board.
The only solution would lie in selling grid power to the farmer at Rs.3.5 or more per unit. Then this theft would not be possible, and depletion of water tables could also be minimised. But that will require tremendous political will.The government hasn’t even thought of these consequences.
