Under the plan, households will be able to buy coal from local governments for no more than PLN 2,000 (EUR 420) per tonne, public broadcaster Polish Radio’s IAR news agency reported.
Meanwhile, local governments will be able to purchase coal from producers and wholesalers for no more than PLN 1,500 (EUR 312) per tonne, according to officials.
The lower house of parliament on Thursday passed the bill with 303 votes in favour, 14 against, and 118 abstentions, state news agency PAP reported.
The measure now goes to the Senate, the upper house of Poland's parliament, for further debate.
In August, Poland's government offered a one-off allowance of PLN 3,000 (EUR 620) to all families that use coal to heat their homes.
