Data series does not include generation from 41.5 MW plant near Colstrip. The Montana 1 plant came on line in 1990. In
1999, it burned 270,000 tons of waste coal.

Includes propane but does not include petroleum coke. A 65 MW plant using primarily petroleum coke has been in operation in
Billings since 1995.

Montana Power Company transferred most of its generating plants in mid-December 1999 to PPL Montana, a non-utility. Data
for 1999 include utility and non-utility consumption at these plants.

'Less than or equal to 0.5 percent.

' Gross generation less the electric energy consumed at the generating station for facilities owned by or selling to electric

utilities and cooperatives. Starting in 1983, annual output of non-utility plants selling into the grid, except for a few akW of

wind, is included. The data do not include generation from wood-fired plants that do not provide power into the grid;

historically, these collectively have produced less (and usually considerably less) than 75 million kWh per year.

^ Includes propane, fuel oil and petroleum coke.

^ Includes Lake Creek plant, which dropped from EIA database after it was sold to Northern Lights in 1995.

Includes public street and hiighway lighting, other sales to public authorities, sales to railroads and railways, and inter-
departmental sales.

U.S. sales 1998-2000 may be missing a small amount of retail sales by non-utilities due to data collection problems
during the transition to a restmctured utility Industry.
^ EIA data on Industrial sales corrected by adding BPA sales, which EIA didn't include this year.

Data calculated by adding Distribution Only Volumes reported by MPC to the Securities and Exchange Commission to
the data reported on EIA Form 861 . The resulting "Commercial" volumes are slightly higher and "Industrial" slightly
lower than had they been reported under Form 861 category definitions.
