If you think the rule of law and fiscal responsibility are key components to growing economic prosperity in Michigan, you probably don’t often look to Illinois for new policy ideas. But there’s at least one lesson Michigan could borrow from the Land of Lincoln: full electricity choice. A recent study from the Compete Coalition estimates that electricity consumers in Illinois saved $41.3 billion from 1999 to 2014 as a result of the state opening up its electricity markets. The state now features the lowest electricity prices in the Midwest.
But things weren’t always so peachy in the Prairie State. As recently as 1997, Illinois had the highest electricity prices in the region. But shortly thereafter, the state embraced electricity choice and forced the regulated public utilities to compete with alternative energy suppliers. The result was Illinois outcompeted every other Midwest state on electricity prices over the next decade and a half.
Illinois electricity prices increased by just 15 percent from 1997 to 2014, moving from about 12 percent above the national average to 9 percent below it. Meanwhile in Michigan, electricity prices increased by 58 percent over the same period. And in Wisconsin, a state that allows for no energy competition, prices rose by a whopping 106 percent.
At the time when Illinois opened up its electricity market, its prices were very similar to Michigan’s and higher than those in Wisconsin. Tracking the difference between these prices over time allows one to estimate how much customers in Michigan and Wisconsin could have saved in electricity costs if they would have paid the Illinois price.
The results are eye-opening. Michigan residents paid $2.3 billion more in electricity costs in 2014 than they would have if prices here matched those in Illinois. Wisconsinites paid $1.3 billion more. But that’s just one year: The total amount Michiganders could have saved from 1999 to 2014 if prices here matched those in Illinois is an incredible $10.6 billion. Wisconsin residents would have saved about half that — $5.6 billion.
The Michigan Legislature is currently considering bills (Senate Bill 437 and House Bill 4298) that would all but choke out the little bit of electricity competition that exists in this state. Based on Illinois’ remarkable success, this seems like a very shortsighted move. Instead of cutting off cost-containing competition, Michigan lawmakers should follow Illinois’ lead and open up our electricity markets.
