No Prices or Devices: How Efficiency Vermont is transforming customers into a demand response resource

Last summer, Opower launched our first-ever Behavioral Demand Response program with Baltimore Gas and Electric (BGE). Unlike traditional DR programs — which are costly technologies that can take years to deploy — Behavioral Demand Response uses real-time digital communications to deliver peak reduction at scale.

As part of the first program with BGE, we helped the utility communicate with 315,000 consumers before and after peak events, saving BGE customers over $7 million.

This summer, we’ve taken the program to new heights, expanding our program to three additional utilities and engaging over one million customers. As opposed to the program at BGE, the new launches at Consumers Energy, Glendale Water & Power, and Efficiency Vermont rely on behavioral science alone — without a price incentive or device — to motivate customers to reduce their peak usage.

The electricity grid has enough capacity today — but don’t stop thinking about tomorrow

Summer peak demand can put tremendous strain on the electricity grid. But, according to a recent report, the U.S. and Canada are prepared to meet this summer’s demand.

In June, the North American Electric Reliability Corporation (NERC) found that both the U.S. and Canada have sufficient reserve margins — a measure of available generating capacity over and above the capacity needed to meet normal peak demand – to reliably serve the country’s electric demand this summer.

In aggregate, U.S. electric demand is expected to peak at about 853,000 MW, which is about the same as last summer. In total, about one million megawatts of capacity exists to meet the expected demand. Below is a map (courtesy of the Energy Information Administration) with reserve margin estimates and targets for summer 2014; in all regions, the estimated reserve margins for summer 2014 are equal to or greater than the target levels.

This is what Tesla owners are doing while you sleep

By day…electric vehicles are taking the world by storm: their sales are doubling every year, their fuel efficiency is off the charts, and some of them can even accelerate from 0-60 mph about as fast as you can say Elon Musk.

By nightthe electric vehicle (EV) community continues to make waves. While you are in bed dreaming about how some day you too might own an electric car, many EV owners are doing something dramatic; something unusual; something that is reshaping the energy landscape.

They are using gobs of electricity.

Average power consumption climbs to 4x above typical
