Opower to save 1 terawatt hour by taking 100,000 homes 'off the grid'

The company's energy savings rate will be high enough at end of 2012 to keep those homes off the grid permanently

Arlington, Va., June 15, 2011 — Home energy management software company Opower announced that its software platform will help U.S. consumers save one terawatt hour of energy by the end of 2012 — the equivalent of taking 100,000 average U.S. homes "off the grid" for a full year.

Moreover, the company's energy savings rate — which has been increasing exponentially since its first energy management program launched in 2007 — will be high enough at end of 2012 to keep those homes off the grid permanently.

Upon the achievement of its goal, Opower's energy savings rate will surpass the rate at which power is generated by the U.S. solar industry.

One terawatt hour of energy is equivalent to:

· Enough energy to power 100,000 average U.S. homes for a year;

· Abating the carbon dioxide produced by 100,000 cars in a year, 11,000 cross-country flights;

· Abating enough carbon dioxide to approximate the creation of 6,500 acres of rainforest;

· Saving U.S. consumers more than $100 million on energy bills.

Currently, Opower is more than a third of the way toward its goal, having saved more than 380 million kWh of energy through more than 30 live utility deployments.

In addition, the company announced the release of a new report by The Brattle Group outlining best practices in measuring the impact of informational-based energy management (IBEM) programs (such as Opower).

Recognizing the potential for information-based programs to drive large-scale gains in energy efficiency, The Brattle Group report outlines statistically rigorous measurement and verification guidelines for utilities and regulatory agencies to use in determining the actual impact of information-based programs.

Opower's measurement methodology and program results have been independently measured and verified by industry analysts and non-profit organizations, including the American Council for an Energy-Efficient Economy, The Brattle Group, Navigant Consulting, Power Systems Engineering, KEMA, the Environmental Defense Fund, and established academics from several institutions.

The company's measurement protocols follow the guidelines specified by Public Utility Commissions across the country, including the California PUC's Measurement & Verification Guidelines and EPA's National Action Plan for Energy Efficiency guidelines.
