OPower, Connexus announce energy efficiency results

Arlington, Va., August 26, 2010 — OPower and Connexus Energy announced the first full-year results of their residential energy efficiency program.

The program, which features OPower’s Home Energy Reports, delivered a 2.1 percent reduction in electrical energy consumption and close to $1 million in annual savings for Connexus customers.

In contrast to some of the company’s initial deployments, the Connexus program was run in a largely conservative district. Connexus, the largest customer-owned utility in Minnesota, is the first utility in the state to offer such a program.

“The OPower energy efficiency program has been a bona fide success in helping our customers save money on their bills, and helping Connexus meet its state-mandated energy conservation goals,” said Bruce Sayler, Manager of Regulatory Affairs and Conservation at Connexus. “Our customers have given us great feedback on the Home Energy Reports and it’s clear that they’re using them to make smarter decisions about their energy consumption.”

The effectiveness of OPower’s Home Energy Reports at Connexus was independently assessed by Power System Engineering, Inc. PSE’s comprehensive analysis incorporated monthly billing data, program specific characteristics, customer demographics and climate data over a three-year period. The study concluded robust and tangible energy savings for the program at 2.1 percent for the first year.

“We’ve seen evidence that OPower’s program was effective in hotter parts of the country, however the program has worked remarkably well here in Minnesota where average temperatures are cooler and electrical consumption per household is a bit lower than in warmer climates,” Mr. Sayler went on to say.

More than 35 utilities have signed up to implement its unique approach to scaling residential energy efficiency, which combines patent-pending data analytics that evaluate customers’ energy usage patterns with cutting-edge behavioral science techniques proven to motivate action.

OPower’s household-tailored Home Energy Reports allow customers to see how their electricity use compares to similarly-sized homes in their neighborhood, and provides personalized suggestions on how to save more energy and money.
