Onsemble, a provider of real-time renewable energy data, has completed the company's hub-height wind data network throughout the Electric Reliability Council of Texas (ERCOT) region.
With the new Texas locations, Onsemble will offer real-time hub-height wind data for 95% of the state's wind farms. The completion and launch of the Onsemble network in ERCOT makes it the first independent source of hub-height wind observations in the region, according to the company.
The new network equates to more than 100 hub-height observation points from towers strategically located in close proximity to the wind farms in Texas. Onsemble sensors measure wind speed, direction and temperature, and provide high-resolution data reports in 10-minute intervals to strengthen wind energy forecasts critical to grid operators, utilities, power traders and wind farm operators, according to the company.
Internal studies show that Onsemble's real-time data could potentially provide double-digit reductions in forecast errors.
‘The electrical grid in Texas, where wind represents approximately 10 percent of the state's energy, has already experienced grid reliability threats as a result of quick changes in the wind,’ says Jon Kilberg, Onsemble founder and president of Torch Renewable Energy LLC. ‘These events could become even more dangerous as wind energy grows and becomes a larger piece of the energy mix.’
In addition to ERCOT, Onsemble is currently operating its real-time data network in the Bonneville Power Administration, the Public Service Company of Colorado and the Southwest Power Pool utility markets, with a nationwide build out planned through 2012.
