New wind farm is on the way

    LOS FRESNOS — Wind farm projects continue to proliferate in Cameron County and surrounding counties, which is good news for the Port of Brownsville, since it handles the wind turbine components that enter the Rio Grande Valley, which creates revenue.

    One of the latest projects under construction is the San Roman Wind Farm by Spanish alternative energy developer Acciona Energy’s U.S. subsidiary. Vessels loaded with wind towers, nacelles, blades and cones connected with the project are streaming into the port at regular intervals.

    The components are stored and eventually loaded onto specially equipped trailers and hauled via 18-wheeler to a site on private land between Bayview and the Laguna Madre.

    Acciona USA says the 93-megawatt project will consist of 31 wind turbines capable of generating enough electricity to power 30,000 homes. San Roman is scheduled to be online by the end of the year, according to the company, which owns seven other wind farms around the United States and more than 200 worldwide.

    The port received the first Acciona components in late May. Each steel tower arrives in four sections that stand 287 feet tall when assembled. The nacelles, which house the generator, gear box and other components, can weigh as much a 140 tons apiece, according to the company.

    The power produced by the project will be delivered to the electrical grid operated by AEP Texas. A substation and connections to the main transformer are already complete. Individual concrete pads for the individual turbines have been poured and the turbines themselves are being erected. It’s Acciona’s first wind farm in Texas, though it’s hardly the state’s first wind farm.

    In the Valley, Cameron Wind, Duke Energy and E.ON Climate and Renewables all have giant rotors spinning, a dense forest of turbines highly visible from I-69E.

    West Texas is bristling with wind towers as well, and for a good reason: Texas has a ton of wind. According to Scientific American magazine, the state smashed its previous all-time record for wind energy production on Dec. 20, when a low-pressure system swept the Panhandle with sustained wind speeds of 20 to 30 mph. At its peak, the weather event produced 13.9 gigawatts, or 45 percent of the state’s total electricity needs.

    Still, as Brownsville port director and CEO Eddie Campirano noted, there’s something special about the coast from a power-generation perspective.

    “One of the things that’s very interesting for us, and why this area is good — I’ve heard this repeatedly — is that we have what they call ‘coastal wind,’” he said. “The wind blows during the day during the greatest demand for energy. In West Texas the wind blows at night.”
