State utility regulators have agreed with NorthWestern Energy’s request to block details on its new coal supply contract from becoming public — at least for the moment. This comes as Montana’s biggest utility moves to buy a larger share of the coal-fired power plant in Colstrip. 

A controversial bill to change the state’s regulation of NorthWestern Energy in a potential deal at Colstrip cleared a critical vote Wednesday in the Senate. 

The proposal encourages the state’s largest monopoly utility to increase its operating share of energy production at one of the coal-fired power plant's four units.

A rewritten Republican plan aimed at protecting the future of the coal-fired power plant in Colstrip is moving forward. But concerns remain about its potential impact on Montanans’ electric bills.

When the so-called Montana Energy Security Act of 2019 was first introduced it drew comparisons to the deregulation of the Montana Power Company in the late 1990s, which skyrocketed electric bills across the state.

Last spring a hailstorm pounded Billings leaving thousands of homeowners filing claims for new roofs, siding, windows, and other property damage. Later several filed complaints with the state Insurance Commissioner that their insurance company dropped their coverage.
