GEI Consultants begins planning on Northern California pumped-storage hydroelectric project


GEI Consultants, a geotechnical, environmental, water resources, and ecological sciences engineering firm, announced that it is providing certain Owner's Engineer services for the proposed Sacramento Municipal Utility District (SMUD) Iowa Hill Pumped-Storage Development project. GEI is a member of the Jacobs Associates team for the project, and SMUD recently awarded the team the Owner's Engineer services contract for preliminary design and construction services on their proposed Iowa Hill Pumped-Storage Project. If constructed, Iowa Hill would be a 400-megawatt pumped storage hydroelectric facility. GEI will lead the design of the 6,400 acre-foot upper reservoir, a lined impoundment that will be formed by an earth- and rock-fill dam with a maximum height of more than 200 feet and a crest length of 5,900 feet. The design of the dam and reservoir will come under the regulatory authority of the Federal Energy Regulatory Commission (FERC) and the California Division of Safety of Dams (DSOD).

The project would utilize an existing reservoir on the American River, from which water would be pumped up to a new 6,400 acre-foot capacity upper reservoir, where the water would be stored. During peak electrical demand periods, water would flow from the upper reservoir to the lower reservoir via a 1,000-foot-deep (305 m) shaft through 3,500 feet (1,067 m) of water tunnels. The electricity generated would connect the existing transmission line that connects SMUD's existing Upper American River hydroelectric project with the district's customers.
The team consists of Jacobs Associates (prime), GEI Consultants, HDR Engineering, AF-Consult of Switzerland, Carlton Engineering, AMEC, IEC Corporation, Northwest Hydraulic Consultants, Stillwater Sciences, Ascent Environmental, Crux Subsurface, and Foxfire Constructors.

GEI's multi-disciplined team of engineers and scientists deliver geotechnical, environmental, water resources and ecological solutions to diverse clientele nationwide. For more information, visit www.geiconsultants.com.
