Opower (NYSE: OPWR), the global leader in cloud-based software for the utility industry, today announced that it has saved over 11 terawatt-hours (TWh) of energy in partnership with 100 utilities across four continents. The figure represents enough energy to power over 1 million U.S. homes for a full year, and is equivalent to more than $1.1 billion in savings on customers' energy bills.

"This is a huge milestone, and it demonstrates that smart software can have a significant, tangible impact on the way utilities and their customers use energy," said Opower CEO Dan Yates. "With Opower's help, utilities are transforming the way they approach demand-side management and playing a pivotal role in shaping a cleaner, safer, and more affordable energy future."

Opower works with some of the largest utility companies on earth, including Exelon, Pacific Gas & Electric, National Grid, Con Edison, Southern California Edison, E.ON UK, ENMAX Energy, ComEd, and TNB in Malaysia. The cumulative impact of saving 11 TWh is equivalent to taking 1.6 million cars off the road for a year. In 2015 alone, Opower and its partners saved 3.2 TWh of energy — twice as much energy as America's largest residential solar company generated over the same time period.

"ComEd has worked with Opower since 2009, delivering nearly 750 GWh of savings for our customers to date," said George Malek, Director of Energy Efficiency Services at ComEd. "Opower's Home Energy Reports have enabled ComEd to scale energy efficiency in a way that achieves extraordinary savings for our customers."

Opower's demand-side management program is driven by the leading customer engagement platform in the utility industry, which uses proprietary personalization algorithms and ingests more than 85 different variables to produce insights and recommendations unique to every customer. To date, Opower's analytics engine has processed more than 500 billion meter reads — making it the largest residential energy data store on earth.
