Sandy-1Mr. Sanders is a Senior Consultant with OnLocation and has over thirty five years of experience creating and exercising integrated energy and environmental models to help clients gain the knowledge necessary to confront the energy and environmental issues that continue to challenge our economic and environmental health. His last 25 years with the OnLocation team has allowed him to use his modeling and linear programming expertise to provide objective quantitative analysis to a wide variety of stakeholders in addressing energy, environmental and climate issues for the U.S.

Mr. Sanders began his career with a government agency that would become the Energy Information Administration (EIA), helping to create and utilize an integrated energy and environmental model, which helped the U.S. address the challenges of the 1973 oil embargo. He continued with EIA for nearly a decade, building, modifying and using models to inform policy makers in their efforts to address a series of energy and environmental issues that challenged the nation. Much of his current focus is on providing analysis of the impacts of proposed environmental legislation on the energy markets. Specifically, climate change policies are expected to press the power sector and refining sector into adopting new less carbon intensive asset choices. Model enhancements and analysis are needed to inform OnLocation’s clients of the economic consequences and physical limitations of investing in these new assets. Each policy choice influences the selection of new assets and results in different carbon migration efficiency and economic outcomes, such as higher direct costs to consumers.

Mr. Sanders has a M.S. degree in Management Science from the University of Miami and also received his B.S. from Miami where he majored in Mathematics with a minor in Physics.
