Founder of GridkraftMs. Chittum researches and develops best practices in federal, state, and local energy policies and programs, particularly those pertaining to combined heat and power (CHP) and district energy. Ms. Chittum wears several hats in her quest to promote the environmental, resiliency, and economic benefits of CHP and district energy: she is a visiting fellow at the American Council for an Energy-Efficient Economy, the manager of strategic initiatives at the International District Energy Association, and the founder of Gridkraft, a Portland, Oregon-based consulting company. She recently spent a year in Denmark as a Fulbright fellow, where she was a visiting researcher with Aalborg University’s Sustainable Energy Planning Research Group. Her research there focused on Danish heat planning and the use of CHP to balance intermittent renewable energy resources. Ms. Chittum’s recent areas of research include measuring the financial value of the resiliency benefits of distributed generation, local energy planning practices, energy resource planning in the United States, the benefits of CHP to utilities, local policy and regulatory support for district energy systems, and the potential for CHP to replace lost coal capacity in the United States. Previously Ms. Chittum managed industrial economic development programs for the City of New York. She holds a master of science degree in Urban Planning from Columbia University and a bachelor of arts degree in Economics from Gonzaga University.

Ms. Karr worked with the Northwest Combined Heat and Power Technical Advisory Panel to develop training and tools for assessment of the viability for installing combined heat and power at commercial and industrial facilities. Assessments include determination of right sizing, selecting the best technology, mechanical and electrical interface, permitting and associated regulations. This is done with the goal of providing customers with a technology that will save them money, improve power and thermal reliability, and reduce their greenhouse gas emissions.
