Energy-efficient appliances and technology developed by Louisville-based GE Appliances & Lighting will help dozens of consumers on Marthaâ¿¿s Vineyard in Massachusetts manage their energy use and costs. The Vineyard Energy Project, a nonprofit organization that promotes the use of clean and sustainable energy, has chosen GE Profile appliances enabled with Brillion technology and GEâ¿¿s Nucleus energy manager to help consumers on the island, according to a news release. As part of a two-year pilot project, about 120 GE Profile appliances will be placed in 35 households, which also will receive the Nucleus technology. Another 15 homes will receive the Nucleus technology only and potentially a control switch on a suitable appliance, such as a hot water heater. To help utilities manage growing peak demand, the technologies can receive signals from power companies to lower or delay power consumption during certain hours of the day. Reducing energy use during peak hours also reduces the islandâ¿¿s need to purchase back-up power to meet demand during energy spikes, according to the release. â¿¿An island like Marthaâ¿¿s Vineyard, where there is little room to build more generation, provides a great test bed for understanding the role of smart-grid technologies in promoting smart-energy management,â¿ Dave McCalpin, general manager of Louisville-based Home Energy Management, a business of GE Appliances & Lighting, said in the release. GE Appliances & Lighting, a division of Fairfield, Conn.-based General Electric Co. (NYSE: GE), has focused on smart-grid technologies. In October, the company announced it would invest $194 million in Louisville to crate a Center of Excellence for â¿¿greenâ¿ and other high-end refrigerators. It established its Home Energy Management business in November. GE Appliances & Lighting has more than 4,000 employees in Louisville.
