Smart meters

The smart metering programs are not new, but their continued rarity speaks in part to the success of power-generating companies in protecting their profit models. Some utilities did install meters in a small number of homes as early as three decades ago, pushed by the environmental movement and a spike in energy prices.

When consumers know the price of their electricity in advance and can tailor their use, even minor changes in behavior can lead to lower home utility bills and less reliance on marginal power plants, said Kathleen Spees, a graduate student in engineering and public policy at Carnegie Mellon.

Consumers who cut back on power use at peak times can do more than just avoid high prices. They can make money, as people in the building on Central Park West learned last summer.

Peter Funk Jr., an energy partner at the law firm Duane Morris who lives in the 48-unit co-op, persuaded his neighbors three years ago to install a single meter to the Consolidated Edison system and then to operate their own internal metering system. That made the building big enough to qualify for hour-by-hour pricing.

When the next day’s prices are scheduled to soar, the building superintendent and a few residents get e-mail messages or phone calls. “We have an orderly plan all worked out to notify people” so they can reduce their power use during the designated times, Mr. Funk said.

The residents save more than just the money on power not used during peak periods, when pricing has been as high as almost 50 cents a kilowatt-hour. During the blackout in July, when parts of Queens were without electricity for up to nine days, the building cut demand as much as 42 percent and sold the unused capacity for about $3,000.

That money helps the building offer a valuable benefit: On most weekend mornings, electricity for residents is free.

“Small reductions in demand can produce very large savings,” said Ms. Spees, who analyzed prices charged within the PJM Interconnection grid, which coordinates the movement of wholesale electricity for 51 million people from New Jersey to Illinois.
