"Due to the current situation ... companies, which significantly reduced activity or decided to suspend it, have caused a big fall in demand for electricity," the government said in a draft of the proposed legislation.
In March, when Poland launched restrictions designed to stop the coronavirus, power consumption fell by 3.95% year on year, the grid operator said.
"Unplanned falls in demand for electricity increase the threat for maintaining the financial liquidity of companies which sell power," the draft said.
The new legislation offers to ease rules regarding mandatory costs which energy companies have to bear when they sell electricity on the power exchange, which analysts say will help them free up capital.
