FRANCES P. WOOD                                                                                                 

Frances-2Ms. Wood is a Director at OnLocation and has over thirty years of energy and environmental consulting experience with government and private clients. She has performed policy analyses using a variety of integrated energy models, including EIA’s National Energy Modeling System (NEMS) that provide comprehensive representations of energy markets. Topical areas include impacts of technology and R&D, tax incentives, and regulatory policies across many sectors of the energy economy. Policy objectives have included the reduction of greenhouse gas emissions, improving energy security through reducing oil consumption and imports, as well as lowering costs to consumers. The electric power sector plays a central role in environmental policy, and Ms. Wood has analyzed the impacts of various proposals for reducing emissions from this sector, as well as its capability to adopt new technologies, such as wind and solar PV. She also has conducted several analyses of alternative transportation policies, including fuel taxes, vehicle mandates and subsidies, CAFE standards, biofuel mandates, and transportation low carbon fuel standards. She led a model development activity to add representation of hydrogen production and delivery to NEMS. She also is working on the construction of a new transportation model for EIA’s World Energy Projection System Plus (WEPS+).  Other areas of interest include the analyses of residential and commercial sector policies, such as appliance standards and subsidies.

Before joining OnLocation in 1997, Ms. Wood was Director of Consulting for the AES Corporation, a global power company. Ms. Wood has an A.B. from Dartmouth College and a M.S. in Engineering Economic Systems from Stanford University.

DANA K. GRISWOLD                                                                                              

UntitledMs. Griswold is a Senior Consultant with OnLocation and has over twenty five years experience designing and implementing models and information systems for many types of clients. She has supported the international modeling at DOE/EIA, including the current WEPS+ model as well as its predecessor the SAGE Markal model. She was the key analyst in the design and implementation of changes made to the SAGE electricity sector, and is currently a key modeler of the new WEPS+ transportation model. She supports the (DOE/EIA) U.S. integrated energy model NEMS (including over 15 years of substantive code changes to the electricity model and more recently implementing the liquid fuels market model integration) and was a major contributor in the development of the Policy Office Electricity Modeling System (POEMS). She has also made significant improvements to the Dynamic Merit Order Dispatch Model (written in Processing, a Java type language). She has successfully undertaken model conversions from several different platforms (Personal Computer, Mainframe, RISC) and integrated widely different models written in different languages (NEMS to POEMS, NEMS to IPM, and NEMS to GAMS models (CTS and LFMM)). She has assisted many government and NGO clients by conducting numerous electricity, energy, and environmental studies.

Ms. Griswold has a B.A. in International Studies from Dickinson College, a B.S. in Information Systems Management from the University of Maryland, and a M.S. in Technology Management from the American University.

REGINALD (SANDY) SANDERS                                                             

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.
