In the U.S., developers of thermal and photovoltaic solar plants face a number of challenges in their efforts to deploy more utility-scale solar power. Some trends, however, are helping solar proponents move this renewable energy source closer to becoming a mainstream generating option.

Hach Co. unveiled its DR 3900 spectrophotometer featuring state-of-the-art radio frequency identification (RFID) technology. Hach, which describes the device as being “similar to a GPS telling you when to turn,” also says that the DR 3900 requires less training and increases confidence in the test results. This helps water and wastewater facilities prevent measurement errors. […]

The Tettex 2293 from Swiss firm Haefely Test AG is the result of extensive research and years of experience testing transformers. A simple one-time-connection system, together with the simultaneous winding magnetization method (SWM), drastically reduces measuring time. The SWM guarantees fast and reliable measurements even on large power transformers with delta windings on the low-voltage […]

Eclipse Inc. introduced the TJSR v5 self-recuperative burner for direct-fired furnace heating applications. The advanced burner design combines a high-velocity flame with fuel-saving recuperation. A space-saving integral eductor pulls the furnace exhaust through an internal ceramic recuperator. The recuperator preheats the incoming combustion air to very high levels, which improves furnace operating efficiency to reduce […]

Massachusetts-based Cabot Corp. recently introduced Enova, an aerogel that is a new high-performance thermal additive designed specifically for insulation coatings. Enova aerogel is designed for application to surfaces that are not already insulated but ideally should be. Cabot researchers have found that applying a 1-millimeter coating containing Enova aerogel to a 200C metal surface meets […]

Distributed wind generator supplier Southwest Windpower unveiled a small wind turbine for commercial and residential use, the Skystream 600, which it claims is the “most efficient power grid-connected turbine in its class, providing an average of 7,400 kWh of clean, low-cost energy per year per household in 12 mph average annual wind speeds.” The company […]

Encorp LLC announced the launch of its Microgrid System Controller, which it says is the industry’s first microgrid system controller to connect onsite synchronous generators with renewable energy assets—such as photovoltaic systems, wind, and microturbines—and then monitor and control the resulting microgrid. The controller has already been successfully installed at a major international defense contractor […]

Thomas & Betts’ Emergi-Lite Nexus Emergency Lighting Management System provides real-time status of the entire emergency lighting and exit-sign system, runs system diagnostics, performs required monthly and annual functional tests, generates maintenance logs, and runs compliance reports from a central control unit. Additionally, the system operates independently of the emergency lighting and exit sign, so […]

At the close of 2009, the U.S. geothermal industry had seen seven new geothermal power plants come online in the previous 12 months. In 2010, only one new power plant was completed.

Perhaps the most echoed sentiment at the American Wind Energy Association’s (AWEA’s) WINDPOWER 2011 Conference & Exhibition, which took place May 22 to 25 in Anaheim, Calif., was the call to extend the Production Tax Credit (PTC), the industry’s policy driver, before it expires at the end of 2012. But that wasn’t the only theme. The throngs of companies and organizations that are shaping the rapidly emerging sector around the world had different notions of the factors that help or hinder the growth of wind power, and POWER was there to listen to their perspectives about everything from grid integration, to offshore energy, to technology innovation.
