Ocean Power Technologies is a U.S. publicly owned renewable energy company, providing electric power and communications solutions, services and related for remote offshore applications. The company's PowerBuoy wave energy conversion technology is theoretically scalable to hundreds of megawatts and the generated energy from wave power can be supplied to the grid via submarine cables. Several projects were undertaken around the world, but the economic viability of the theoretical concept has been problematic. Ocean Power was involved in several large PowerBuoy projects, including a very large Australian project with Lockheed Martin from 2012–2014, when they determined that "the project wasn’t 'commercially viable,' and [the company] changed its strategy. It has since commercialized the technology by providing power and communications to remote sites such as offshore oil fields." Ocean Power Technologies Australasia Pty Ltd, OPTA is an Australian-owned subsidiary of Ocean Power Technologies Inc, previously engaged in wave power projects in Australia. Ocean Power Technologies Limited is the UK-based wholly owned subsidiary. Wikipedia
