In June 1989, DOE held public hearings to support the expanding demand for energy in the United States. The purpose was to begin determining the undeveloped potential hydropower resources. As a result of the meetings, and through partial analysis of the database of undeveloped resources by industry groups, DOE discovered that the data on potential hydropower included redundancies and errors which reduced confidence in the published estimates of the developable hydropower potential. As a result, DOE established an interagency hydropower resource assessment team to determine the resource. The team completed a preliminary assessment of potential hydropower resources in February 1990. DOE has continued these resource assessment activities to develop a basis for correcting these deficiencies. The goal is to assemble a resource database of all potential hydropower sites in the United States for use as a planning tool to determine the viable national hydropower potential.
Virtual Hydropower Prospector
The Virtual Hydropower Prospector (VHP) is a geographic information system (GIS) tool is designed to assist you in locating and assessing water energy resources in the United States.
Hydropower Evaluation Software
To assess the hydropower potential in any area of the United States from a national perspective, a uniform set of criteria was developed and a probability factor computer model, called Hydropower Evaluation Software (HES), was designed to standardize the assessment. HES offers the PC user the ability to factor in environmental attributes of a hydropower site to calculate a relative development suitability factor for a project.
