Grid-tied residential storage expected to overtake off-grid this year

After walking the SPI show floor, there’s no denying the residential storage market is developing quickly. In fact, GTM expects that 2017 will be the first ever in which grid-tied residential battery storage system deployments outnumber new off-grid and grid-independent systems across the United States. According to its report, U.S. Residential Battery Storage Playbook 2017, the U.S. […]

AWEA 2012 Show Recap

Despite comments from many attendees saying booth traffic was slow, I think AWEA’s Windpower 2012 was a success. I even have the blisters to prove it. AWEA hosted the show in Atlanta, a major manufacturing hub, and consisted of two huge halls with well over 1,000 exhibitors. The “slow” traffic can be attributed to the state

Michigan composites company exports to Spain

Energetx Composites of Holland, Michigan, is exporting a complete set of 45.3 meter wind blade molds from its Michigan facility. The molds are shipping to Aeroblade, based in Minano, Spain. Energetx Composites is using an identical mold set in its Holland facility to manufacture the same 45.3 meter wind blade for the North American market.

Wind Reliability: Maintenance-free hydraulic accumulators

Wind turbine pitch, yaw, and brake systems use either electric or hydraulic actuation. The hydraulic systems use high-pressure, gas-charged hydraulic accumulators. Typically, either a bladder or a piston accumulator is used. Maintenance-free, metal bellows accumulators can offer an advantage in these applications. A piston accumulator consists of a cylindrical metal body with end caps and
