New Jersey, USA — ESI-AFRICA.COM — 02 March 2011 – Ocean Power Technologies (OPT) “’ a leading renewable energy company specialising in cost-effective, advanced, and environmentally sound offshore wave power technology “’ has announced the completion of the first of its new generation utility-scale PowerBuoy device, the PB150.

The PB150 PowerBuoy is the largest and most powerful wave power device designed by OPT to date. With a peak-rated power output of 150 Kw – equivalent to the energy consumption of approximately 150 homes – the PB150 is designed for use in arrays for grid-connected power generation projects worldwide, a company press release states.

The development of the device, built and assembled at Invergordon, Scotland, has used the skills of local firms and represents a multi-million pound sterling investment in the region. It is currently being prepared for ocean trials at a site approximately 33 nautical miles from Invergordon, off Scotland’s northeast coast.

The sea trials are expected to commence as soon as weather conditions permit. The company is seeking additional financing for the commercial use of the buoy after the trial phase has been completed, including its possible deployment at various potential sites.

A second PB150 is already under construction in the United States for a proposed utility-scale project in Oregon, and the company is involved in other planned projects in Australia, Japan and Europe that may use the PB150.

The ocean trials off Scotland have been fully authorised by the Scottish Government. In addition, Marine Scotland “’ the directorate of the Scottish Government responsible for regulating marine and fisheries matters “’ consulted with interested parties and stakeholder groups covering areas such as local wildlife, shipping, oil and gas and fishing interests, before the go-ahead was given.
