Using JEDI Data
Jobs and economic development impact analysis requires project specific data, state specific input-output multipliers and personal expenditure patterns, and price deflators.
Project specific data:
- Construction Costs (materials and labor)
- Equipment Costs (feed handling, boilers, process, etc.)
- Annual Operating and Maintenance Costs (personnel, materials and services)
- Other Parameters (financial — debt and equity, taxes and land lease)
- Other Costs (engineering, insurance, etc.)
Many developers consider this type of information proprietary due to competitive forces in the marketplace. In addition, project specific differences can and do significantly impact costs. As a result, it is impossible to identify a set of default values that will correctly reflect the idiosyncrasies of every power generation project. Yet, JEDI provides default values allowing users to run the model, obtain a broad estimate, and investigate how various inputs affect model outputs.
Default values represent average costs and spending patterns developed from a number of sources, including ten years of research and analysis of renewable and fossil fuel resources. Other resources include personal communications and anecdotal evidence gathered to complete this model, previous renewable and fossil fuel energy studies, and project-related case studies.
Where Do We Get Our Data?
Multipliers and personal consumption patterns were derived from IMPLAN Professional™ state data files. IMPLAN data files are updated periodically.
Where Can Users Find Their Own Data?
Users can obtain their own data from a variety of sources, including:
Non-IMPLAN users, or those unfamiliar with input-output modeling, have several options for gathering the necessary data to perform a more specific county or regional analysis.
- Follow a similar process (as described above) to derive the aggregated multiplier and consumer expenditure data from another input-output modeling tool;
- Purchase the necessary aggregated multiplier and consumer commodity demand data from someone skilled in input-output modeling (IMPLAN or another modeling tool); or
- Purchase the necessary aggregated multiplier and consumer commodity demand data directly from Minnesota IMPLAN Group, Inc.
