The state government has imposed an electricity surcharge of 10 paise per unit on industrial and commercial consumers to finance its scheme to provide 25,000 solar pumps to farmers, a senior official said on Sunday.

In view of the forthcoming Lok Sabha and Maharashtra Assembly polls next year, state Energy minister Chandrashekhar Bawankule had announced that farmers would be provided with one lakh solar pumps in three phases between 2019 and 2021, of which 25,000 would be given in the first phase.
