Clean Power Research was founded by Thomas Hoff, Ph.D., as a consulting company focused on the economics of renewable energy. Since then, Clean Power Research has evolved into a world-class software company serving 10 of the top 10 Fortune 500 utilities and many of the world’s largest renewable energy companies.
Today we’re focused on expanding our impact with new software technologies that help solve the energy industry’s most challenging problems.
Jeff Ressler is chief executive officer of Clean Power Research. In his more than ten years at the company, he has overseen the inception of the SolarAnywhere® and WattPlan® software families, and grown PowerClerk® from a nascent, online incentive processing tool into a powerful, general purpose energy program automation solution. A software industry veteran, he has a track record of delivering highly available cloud-based solutions to customers as well as deep experience building effective functional teams across engineering, product management, sales, marketing, business development, support and operations.
Jeff’s interest in the clean technology industry is driven by the fast pace of technical innovation and the opportunities to help inform markets about the value of renewable energy technologies. Seeing the parallels with the early software and PC markets, Jeff is applying his insight and expertise to delivering software solutions that quickly and cost-effectively evaluate the financial impact of renewable energy technologies.
Jeff’s career includes stints at both Oracle and Disney in addition to more than 10 years at Microsoft. During his tenure at Microsoft, Jeff served as Director of Product Management for Exchange Server and Lead Product Manager for SQL Server, among other roles. For more than two years, he was the speech manager for Bill Gates, who was Microsoft’s Chairman and Chief Software Architect at the time. Jeff holds a degree in Industrial Engineering from Stanford University.
