Chicago, October 25, 2011 — S&C Electric Co. completed a VAR compensation system that helps the Edison Mission Energy Goat Mountain Wind Ranch meet the Electric Reliability Council of Texas' new grid interconnection requirements.
Retrofit projects, such as the one at Goat Mountain Wind Ranch, are increasing as renewable plants and utilities ensure existing assets and systems comply with evolving grid requirements. Compliance with these requirements allows renewable energy projects to bring renewable sources on to the grid.
S&C's VAR compensation system was retrofitted at the 150-MW Goat Mountain Wind Ranch near San Angelo, Texas, developed and owned by Edison Mission Energy. The retrofit project helps ensure production at the wind farm is not curtailed.
S&C first analyzed the impact of the new requirements on the Goat Mountain plant, then provided a complete engineer-procure-construction solution that successfully navigated the complex challenges associated with retrofitting a VAR compensation system at an existing plant.
As part of the EPC solution, S&C provided a PureWave DSTATCOM Distributed Static Compensator. The PureWave DSTATCOM today enables production of gigawatts of wind energy by allowing plants to meet even the strictest grid codes.
The VAR compensation system, which was designed, installed and commissioned by S&C, also includes a mechanically switched capacitor and reactor banks controlled by the PureWave DSTATCOM for a complete and cost-effective solution.
