The destruction of the turbines and auxiliary equipment at Russia’s Sayano-Shushenskaya Hydro Power Plant in August 2009 claimed the lives of 75 workers and wrecked an indispensable source of electricity that will take years to fully restore. The disaster, as this report explains, was predictable and preventable.

As wind and solar energy capacity in the U.S. continues to grow, compressed air energy storage (CAES) and other bulk energy storage technologies will increasingly be used to help balance electrical supply and demand.

Composite materials are ideal for producing wind turbine blades because of their strength, light weight, and ability to be tailored to provide the precise mechanical properties needed for any blade design. Now, best practices originally developed for rotorcraft blade manufacturing can be applied to designing and manufacturing wind turbine blades that are constructed from composites.

Recent mandates require government facilities to develop energy policies that enable energy conservation, increase the use of renewable energy, and improve energy security. Utilities with government facilities in their service territory may have opportunities to develop solar and other renewable energy projects that help them meet state renewable portfolio standards while increasing a government facility’s usage of renewable energy. The key to such a win-win proposition is careful structuring of the project agreement to leverage each party’s assets.

In 2010 investment in wind power continued to accelerate, particularly in California and Texas. California also entered several solar projects in the race for financing. The finish line that renewable power developers and their partners are racing to meet is a December 31 deadline to qualify for federal cash grants.

Electro Static Technology’s AEGIS WTG wind turbine grounding ring seeks to prevent bearing damage that could otherwise cause generator failure by safely channeling harmful shaft currents away from bearings to the ground. Maintenance-free, effective at any wind turbine speed, and available for any-size generator, the ring is designed for OEM installation or easy up-tower retrofit. […]

Neptune Mixer Co., a division of Neptune Chemical Pump Co., announced that its Series HGL mixers are now available in both electric and air-driven models. The Series HGL mixers are ideal for intermediate bulk container (IBC) and poly tote applications found within the wastewater treatment and chemical industries. Explosion-proof models are also available. Neptune’s HGL […]

New Pig Corp. recently introduced PIG Transformer Containment Bags, carriers designed exclusively for the safe transport of polychlorinated biphenyls (PCBs) and mineral oils. The bags feature high-capacity straps to ensure safe lifting of up to 4,800 pounds for transport on diamond-plate truck beds without rips or wear. To provide ultimate weather, puncture, and tear protection […]

Spirax Sarco released a new control valve range, SPIRA-TROL, in 6- and 8-inch sizes and with more control options. The company says the valves are easy to maintain and do not require any special tooling due to the “clamp-in-seat” design, resulting in reduced downtime and cost of ownership. Valve size ranges have been extended due […]
