MidAmerican Energy wants to boost electric rates, and is proposing a first-ever "environmental compliance" adjustment clause to reflect those costs on customers' electric bills.
The privately owned utility says it plans to seek approval for an overall 3.5 percent rate increase in February 2012. Interim rates could be in place by March.
Rather than file a general rate case, the utility has outlined in filings with the Iowa Utilities Board (IUB) that it wants to add two automatic adjustment clauses for "environmental compliance" and "coal and coal transportation" costs.
