GE/Briggs & Stratton Standby Generators Promise Efficient Whole-Home Power

Tuesday, September 8th, 2009
According to Briggs & Stratton, the 10-kW standby generator with Symphony power control system can power the same appliances as larger competing units.

According to Briggs & Stratton, the 10-kW standby generator with Symphony power control system can power the same appliances as larger competing units.

Earlier this year, GE introduced a line of Briggs & Stratton-built standby power generators. Briggs & Stratton marketing officials, who visited ebuild’s Washington, D.C., office today, said the line is unique because each system includes a generator and a transfer switch (usually sold separately); a power management system in the specially designed Symphony transfer switch allows the modestly priced 10-kilowatt system ($2,898) to provide whole-house power during power outages for 73% of American homes. (Officials said the 10-kW is sufficient for 2,400-square-foot houses.)

Nevertheless, Deadra Richelle, assistant marketing manager for Briggs & Stratton, also said that the cost of installation could double the initial system price. Installation of standby generators–GE and all other brands–averages $2,000 to $3,000, but the cost could be significantly higher and varies depending on the installer. “There is no way to normalize the installation costs,” Richelle said, noting that independent electricians and plumbers who install for The Home Depot set their own fees. The GE line is sold through The Home Depot and Briggs & Stratton dealers.

With the launch of the new product line, which also includes 12-kW, 15-kW, and 20-kW models, GE also unveiled a Web site designed to make product selection easier for consumers.—Jean Dimeo

White Paper Explains How to Integrate Propane Backup Systems Into Renewable Energy Setups

Thursday, August 27th, 2009

The Propane Education & Research Council (PERC) released the white paper Propane-Enhanced Renewable Energy Systems, a 36-page document that describes why and how contractors should implement supplemental propane backup for their renewable energy systems.

Even the most robust alternative energy systems are bound to face some downtimes over their lifetime, whether from cloudy days, fluctuating ground temperatures, or other interruptions. “Nearly all renewable energy sources, when expected to provide the same comfort and convenience modern Americans now enjoy, must be supplemented with efficient and environmentally respectful forms of conventional energy,” the paper asserts.

With thorough descriptions and helpful schematics, the document runs through some of the most common renewable energy setups—including solar hot water, photovoltaics, and air-source heat pumps—and explains how to integrate a propane backup system.

John Siegenthaler, engineer and heating specialist and the paper’s author, told Hanley Wood editors that 90% of the hardware used in these systems is hardware installers are already used to using.

The white paper is available for download on PERC’s Web site. –Katy Tomasulo
