One company that has successfully stayed more or less in business throughout the permitting process for traditional pumped hydro storage is Symbiotics, which is based in Utah. They received preliminary permits from FERC for two Utah pumped-hydro projects, one that has a capacity of 700 MW in Rich County, due online in 2020, and another, in Piutte County, Utah, with a capacity of about 1,330 MW, due online in 2017.
During this long drawn out process, Symbiotics was bought out by a new kind of hydro-power startup, Riverbank Power, which acquired Symbiotics in a merger a few months ago. Riverbank Power is the highly innovative company we wrote about last year that uses gravity under rivers to store hydro power: Pump Hydro Underground to Store Wind Power.
Vince Lamarra, founder and former CEO of Symbiotics, and now vice president of project development at Riverbank Power, is sanguine about the time it takes to get permitted and built; about a decade.
"In a best-case scenario, you might be able to get a federal license in five years, but then it takes another two years for the engineering and then three more years to build a pumped-storage project, and they cost about $1.5 billion to $2 billion to build, because they are very large facilities," he said.
