Californian utility company Pacific Gas and Electric (PG&E) has signed an agreement with the City and County of San Francisco and the Golden Gate Energy Co to conduct a comprehensive study to assess the possibilities for harnessing the tides in San Francisco Bay.

The study will begin this summer and is estimated to take approximately twelve months. If the study results were to support the development of a project, the undertaking would require governmental regulatory review and approval, including public participation.

As a result, the parties estimate that operation of a project would be at least three to five years away.
