New World Power Corporation of Lime Rock, Connecticut is now practising what it preaches. Since early March virtually all the power required by its manufacturing facility at Waitsfield, Vermont, has been produced by a 50 kW wind/photovoltaic/diesel village power system. Last month the company announced it had disconnected the Waitsfield premises from the grid. The system, which can be increased in size in 100 kW increments, uses low cost high reliability rotary inverters and is controlled by New World's proprietary control system. Markets for the system are seen in Alaska, northern Canada, Mexico and Central and South America with first shipments this year. The Waitsfield project is supported by the National Renewable Energy Laboratory, the Alaska Science and Technology Foundation and Sandia National Laboratories.
