Jay Marhoefer has been many things in his 35-year business career: utility consultant, mathematician, project manager, and attorney. In the early 2000’s, he envisioned a future of networked, distributed energy storage and self-driving cars and detailed his thoughts in his 2007 book, “Re-energizing America”. He coined the phrase “Intelligent Generation” to mean the co-ordinated optimization of a network of distributed energy assets.  This led to the development of two algorithmic energy optimization patents and the creation of IG in 2009. This energy future is now upon us and Jay continues to pursue what he does best: analyzing complex problems and creating novel, workable, and economically compelling solutions for implementation.

Jay has worked for some of the premier professional services companies in the world: Accenture, Price Waterhouse, and Latham & Watkins and brings a culture of quality delivery to all IG clients.
