Success Stories

The following are examples of active OpenEI users, organizations that rely heavily upon OpenEI data, or groups who have in some other way played a key role in the success of OpenEI:


Reegle logo.png
reegle Country Profiles are currently pulling renewable resource maps, tools and programs from OpenEI country pages. Additionally, hundreds of definitions from the Openei Glossary have been shared with the reegle Thesaurus.


For OpenEI, cooperation with REEEP (the Renewable Energy and Energy Efficiency Partnership, and organization behind reegle) means seamless access to important information, less duplication of effort, opportunities for joint ventures, collaboration on cutting-edge development projects, and a partnership that has already resulted in a measured increase in both funding opportunities and the number of visitors to our mutual sites.

Green Button

OpenEI is the recognized go-to site for Green Button Apps. The catalog contains apps from contests like the Apps for Energy Challenge as well as apps submitted directly to OpenEI by developers and organizations. OpenEI has also helped with the promotion of the Green Button initiative by providing content such as the participation map to the White House.


OpenEI contains numerous energy related datasets and details, but sometimes users have questions about using these data. OpenEI's Community pages are a place where users can search for answers and post questions that have not yet been answered. One great example of user engagement was assisting an international user with one of the international datasets hosted on OpenEI for their thesis/dissertation. The user had questions regarding the data format and the best way to work with it. The Community format allowed an OpenEI administrator to provide a detailed answer in a timely fashion for the user.

CKB Group

The Climate Knowledge Brokers Group is an emerging alliance of around 50 of the leading global, regional and national websites specialising in climate and development information. Their focus is on primarily online initiatives, and those that play an explicit knowledge brokerage role, rather than being simply institutional websites. OpenEI is proud to be home to the CKB Group portal, and an activate participant on their strategic direction panel.

NREL's BEopt software

Beopt logo no text.png
NREL’s Building Energy optimization (BEopt) software evaluates residential building designs and identifies cost-optimal efficiency packages at various levels of whole-house energy savings along the path to zero net energy. BEopt now uses OpenEI’s utility rate database to make thousands of residential utility tariffs available directly in the BEopt user interface. Accounting for more complex time-of-use and tiered rates is essential to identification of cost-optimal packages of efficiency measures and solar PV generation.

Congressional Briefings

EERE Legislative Affairs routinely uses OpenEI as a source of information on congressional districts and energy-related companies when preparing briefings for key US decision makers.
