The feasibility study will start this summer and should be complete in about a year. They will measure how much energy might be available and look at the technologies that are available to capture some of that energy as well as do an environmental impact study. PG&E will kick in $1.5 million to fund the study by outside consultants and San Francisco will put in another $346,000. A study by the Electric Power Research Institute in 2006 indicated that the tides of San Francisco Bay could provide one of the biggest sources of tidal power in the world.
