Simulating distributed energy resource adoption

The Distributed Energy Resource (DER) market is evolving quickly, and the pace of change is accelerating. We help you understand where it's headed – over time and spatially. We can accurately assess the economics of and forecast market adoption of distributed energy resources, including rooftop solar photovoltaics (PV), battery storage, electric vehicles, and energy efficiency resources. We offer industry-leading approaches and unparalleled accuracy in our forecasts, taking the guesswork out of understanding the future of these markets.

system dynamics modeling

We live in a complex world – one that is ill-suited to simplistic solutions. We have 15 years of experience applying the System Dynamics methodology – an approach conceived and cultivated in the halls of MIT – to simulate the behavior of complex systems. The models our staff have developed have been used in dozens of client engagements with some of the largest electric utilities, regulatory agencies, and conservation organizations in North America. Incorporation of relevant feedback loops, stocks and flows in our models is enhanced by our ability to integrate these models with linear or nonlinear optimization and Monte Carlo analysis – making our approach second to none.
