The Energy Department reports that the average residential rate for electric service was lower than last year in every month this year through August (the latest month of the data). Except this March.

It also reports that the average commercial rate was lower than last year in every month this year. No exceptions.

Year-to-date, the average residential rate was 12.54 cents per kilowatt-hour this year. That’s lower than last year, by 0.9 percent, when it was 12.65 cents.

Demand-side management programs are not new to the electric utility industry. 

Arguably the most effective peak management tool was the invention of commercial and industrial interruptible service and tariff offerings. Electric utilities introduced effective residential peak shaving programs in the 1970’s as well.

More good news yesterday for electric service customers.

The Commerce Department published the numbers it uses to estimate the gross domestic product. Including personal consumption expenditures, which is seventy percent of the GDP. 

Including the expenditures for cars, clocks, carpet, computers, cereal, clothing, cosmetics, child care, cabs, clubs, cable, cell phones and casinos. That’s just the c’s. 

And including the expenditures for electric service. 

It is the process of setting a return on equity that is fair to both shareholders and consumers that demonstrates the art and science practiced by regulators. One case reported here provides a good glimpse at the entire range of issues put before regulators: a decision by the Michigan Public Service Commission setting electric rates for Consumers Energy Company.
