Sweetwater Wind has awarded a $2.6 million contract to S&C Electric Co. for upgrades to parts of its 585 MW wind farm in Sweetwater, Texas.

The companies say the enhancements will enable Sweetwater Wind to meet new renewable energy generation interconnection standards that have been enacted by the Electric Reliability Council of Texas (ERCOT). ERCOT has revised its grid code related to reactive power capabilities, requiring Sweetwater Wind to provide a lagging power factor capability of 0.95 or less and a leading power factor capability of 0.95 or less at the point of interconnection.

"S&C worked with Sweetwater Wind to evaluate the current system and develop the best long-term solution that can quickly meet the new requirements, which is critical to avoiding production curtailments," says Dan Girard, director of renewable energy and energy storage business development for S&C. "This upgrade will help Sweetwater Wind maximize its wind project production while ensuring the grid is protected."

S&C is engineering and constructing a complete system using mechanically switched capacitors in three substations at the site. S&C is also designing and installing the control system in the plant's east substation to manage the capacitor banks and switches.

The project is expected to be completed by June, the companies say.
