Campobello Island

Campobello Island, while not the site of the project, played an integral part in the Passamaquoddy Tidal Power Project. Dexter Cooper, the engineer behind the idea, had a summer home on Campobello and often observed the powerful tides of Passamaquoddy and Cobscook Bay. President Franklin D. Roosevelt was a powerful supporter of the tidal power project and, like Cooper, owned a home on nearby Campobello Island.

Exhibit and Working Model of the Tidal Power Project

Conceived by hydroelectric engineer Dexter P. Cooper in 1920, the Passamaquoddy Tidal Power Project aimed to harness the power of ocean tides to generate electricity. With more than 70 billion cubic feet of water flowing in and out of the bay with each changing tide, Passamaquoddy was the ideal choice for such a project.
