The Federal Energy Management Program (FEMP) offers resources to help federal agencies plan and implement distributed energy projects.
Also see FEMP's collections of case studies, publications, and tools.
Tools
-
Identifies and prioritizes renewable energy projects at a single site or across a portfolio of sites in cities, states, or countries. -
Compares the combination of capital costs, operations and maintenance, performance, and fuel costs -
Tool helps agencies manage existing solar photovoltaic systems, benchmark performance, manage needed repairs, and adopt ongoing best practices. -
Maps allow users to explore U.S. renewable energy resources including biomass, geothermal, hydrogen, marine and hydrokinetic, solar, and wind. -
Examines the viability of three solar technologies in the U.S. with a high-level annualized economic calculation -
Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems throughout the world. -
Customizable template for federal government agencies seeking the construction of one or more on-site solar PV systems. -
A map listing clean energy purchasing programs offered by vertically integrated utilities (i.e., those responsible for the generation, transmission, and distribution of electricity in their service territory).
