On November 6, 2017, the U.S. Department of Energy (DoE) sponsored an Energy Storage Seminar for Western State Regulatory Commission Staff in Salt Lake City. The summit took place at the offices of the Western Electric Coordination Council, with training provided by staff from DoE, Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratories (SNL). Staff from regulatory commissions in 10 western states attended. The seminar was designed with three key purposes in mind: to facilitate a discussion among regulatory staff about the challenges they face in current regulatory proceedings involving energy storage, to provide training to establish a baseline understanding of current energy storage technology and economics, and to solicit feedback from program participants about how future DoE-funded research and training on the topic of energy storage can be designed to meet state needs. Feedback suggests that future seminars and Energy Storage Program research should be focused on developing and sharing practical information about the impacts of energy storage on regulatory processes, that networking activities are highly valued by regulatory staff, and that program stakeholders want to be engaged in planning future events and research efforts.
