Lumidyne staff (Cory Welch), while employed by the National Renewable Energy Laboratory (NREL), Summit Blue, and Navigant, has simulated the adoption of distributed energy resources (e.g., solar PV, combined PV & storage, and advanced technology vehicles) for over a decade using well-established methodologies, including System Dynamics, Bass diffusion, consumer choice theory, optimization, and discounted cash flow analysis.
Lumidyne staff (Cory Welch) originally developed a model to simulate the adoption of energy efficiency technologies by integrating Bass diffusion with stock turnover dynamics while employed at the National Renewable Energy Laboratory (NREL). He further applied this modeling approach at Summit Blue and Navigant Consulting. The model formed the basis for NREL's Stochastic Energy Deployment Systems (SEDS) model, and has also been used by Navigant Consulting to estimate energy efficiency potential for roughly 20 electric and gas utilities in North America over the last decade.
Lumidyne staff (Cory Welch), while employed at Navigant Consulting, re-developed the Regional Portfolio Model (RPM) for the Northwest Power and Conservation Council. The model employs many classic System Dynamics methods, including multiple stocks and flows, feedback loops, material and information delays, behavioral expectation trending algorithms, and co-flows. It is highly transparent for stakeholder review, and can be run using an online interface not requiring any software installation (Image adapted from online model - click link below).
