Milwaukee-based We Energies says energy bills for January 2014 may be 35-40 percent higher than they were a year ago. We Energies delivered more natural gas to its customers in January than any other month in its history.
However, bills were less than they were in 2009, when natural gas prices were higher.
January 2014 was 25 percent colder than January 2013, and the November-January stretch was the coldest start to a heating season since 1976-77, according to We Energies.
We Energies serves electricity and natural gas to more than 2 million Wisconsin customers, mostly in the Milwaukee and Appleton areas. It also has more than 28,000 customers in Upper Michigan.
