E Source Announces the Acquisition of EnergyWindow Inc.

EnergyWindow acquisition expands E Source offerings and provides large energy
users with a powerful combination of expertise and technology to mitigate
rising energy costs and 'carbon usage.'

BOULDER, Colo., July 31 /PRNewswire/ -- E Source (http://www.esource.com)
today announced the acquisition of EnergyWindow Inc.
(http://www.energywindow.com), a leading provider of online tools and services
that support energy-sourcing decisions and procurement. The acquisition was
completed in July 2008 for an undisclosed amount, according to company
officials. The addition of EnergyWindow will expand E Source's offerings for
corporate energy managers, providing solutions for energy supply management
that include technology-based tools and information designed to help large
energy users mitigate the cost of the natural gas and electricity required to
power their business facilities and manufacturing plants.
"Businesses are facing an ever-changing energy market -- one that includes
the likelihood of steadily increasing energy prices in the short and longer
term and a considerable amount of uncertainty related to energy and carbon
risk," said Ronald Gerrans, CEO of E Source. "E Source's acquisition of
EnergyWindow brings together two strong, innovative companies. Together, we'll
be able to deliver the tools and services corporate energy managers need to
effectively take control of their energy and carbon risk and make better
energy supply and management decisions," he said.
The combined company will offer an integrated, comprehensive range of
offerings in three key areas: energy conservation (usage management), supply
management (energy procurement), and sustainability (how to mitigate carbon
risk and meet green power goals). "This integrated approach will allow us to
help energy managers greatly simplify often-conflicting energy management
requirements," Gerrans stated.
The business intelligence that E Source experts provide to utilities and
large energy users includes predicting and assessing trends and technologies
related to energy efficiency, utility customer satisfaction, program design,
marketing, customer management, and sustainability. EnergyWindow's information
technology-based tools and strategic consulting help large energy users manage
their energy supply cycle from cost forecasting through actual procurement of
natural gas and electricity.
"Talking with E Source, it became clear that combining our companies would
enable us to bring to bear substantially greater human, financial, and
technical resources for developing additional innovative offerings related to
energy conservation, energy supply management, and greenhouse gas mitigation
requirements," said EnergyWindow President and founder Dr. Jack Mason.
EnergyWindow Acquisition Logistics
With this acquisition, EnergyWindow becomes fully integrated into the E
Source operation headquartered in Boulder, Colo. Dr. Mason will lead the new
combined E Source offering for corporate energy managers.
EnergyWindow has already processed more than 10,000 energy procurement
transactions for more than 100 recognized national companies (more than a
third of which are Fortune 1000 companies) that have resulted in savings of
more than $138 million on $816 million in energy supply costs. "This is just
one example of the kind of innovation that can be enhanced through the
combined resources of E Source and EnergyWindow," noted Dr. Mason.
"Corporate executives have expressed their frustration with their
inability to accurately budget for future energy costs and manage their energy
and carbon risks. Joining forces with EnergyWindow will enable our common
vision of helping businesses improve their bottom lines by optimizing their
energy strategies," said Gerrans. "While our current business relationships
will continue to grow, we look forward to extending our joint offerings into
new markets."
