After falling since 2009, the rates that most Maine homes and businesses pay for electricity are rising again, as the cost of upgrading New England's power grid begins to show up in their utility bills.
The Maine Public Utilities Commission announced recently that the delivery portion of Central Maine Power Co. bills will go up 7.1 percent starting this month. Bangor Hydro-Electric customers will see a 4.5 percent rise.
The initial increases are modest: A CMP home customer with an average monthly bill of $81 will see another $3 or so.
However, this little-noticed change signals the start of rate increases that will play out over the next five years or so. And there's not much that politicians such as Gov. Paul LePage, who repeatedly says that lowering electricity costs is one of his top priorities, can do about it.
That's because an estimated $4.6 billion in transmission projects are planned or under way in New England through 2016, and Maine's share of the investments could be as high as $375 million.
That would add a couple of pennies to each kilowatt-hour consumed in the average home, or another $12 or so per month, according to calculations done by The Portland Press Herald and reviewed by the PUC.
Rising transmission rates are only half the story, however.
Overall electric rates eased in recent years primarily because of record-low prices for natural gas, which is used to generate much of New England's power. Wholesale gas prices are stable now, and that may help temper the transmission effect for home customers over the next year or so. On the other hand, if the demand for natural gas grows as the economy eventually recovers, Mainers also could see a modest rise on the energy portion of their bills.
These factors show how regional transmission polices and market forces -- rather than hot-button programs such as renewable-energy subsidies -- are the primary drivers of Maine power bills.
Even so, government mandates do contribute to overall costs. In the response to a law enacted this year on behalf of the LePage administration, the PUC is starting an inquiry into the costs of programs that include renewable-resource requirements, low-income assistance and money to fund Efficiency Maine.
"It's whatever else we're adding to the bill," said Kenneth Fletcher, LePage's energy director. "We want to stop the bleeding. We don't want to add more in."
The pending rate increases don't come as a surprise to Fletcher or anyone else who follows Maine's energy industry. They were predicted more that two years ago, when state regulators were reviewing the need for CMP's Maine Power Reliability Program.
Building transmission is profitable for utilities, which, per federal law, enjoy a high rate of return on those investments. Despite arguments from intervenors and the PUC staff that the state could have a reliable grid for less money, regulators approved what's considered to be Maine's largest construction project, costing $1.4 billion.
Now under way, CMP's project is designed to meet strict standards aimed at preventing blackouts. As a side benefit, it also improves connections to some power producers, including wind farms in western Maine.
In one sense, it's a good deal for Mainers, who pay only 8 percent of the cost. The rest is spread among other New England power customers. The thing is, Mainers also must share the cost of similar projects in other states.
Utilities say it's a once-in-a-generation effort to upgrade the region's power grid.
"This is basic infrastructure that everyone relies on," said John Carroll, CMP's spokesman. "You have to make big steps forward for what are long-lived assets. You have to think long-term when you look at transmission rates."
