NEPSI recently shipped two 34.5KV metal-enclosed capacitor banks to Black Spring Ridge Wind project located in Vulcan County, Alberta. The two capacitor banks will help the 300-megawatt project meet Alberta Utilities interconnect requirements.

The project is comprised of 166 V100-1.8-megawatt turbines and is expected to be the largest wind project in Western Canada. Situated on 48,000 acres of rolling hills and grasslands, the project will provide clean energy to serve over 140,000 households once fully completed.

NEPSI scope of supply included two fully assembled metal-enclosed capacitor banks totaling 56 MVAR. The banks are equipped with Southern States Transient Free Switching Technology that utilizes pre-insertion resistors to damping switching transients. Additionally, the capacitor banks are "filter ready", meaning they can be easily converted to harmonic filters should the wind project have difficulties with harmonic resonances.

Planned commissioning of the capacitor banks is set for early December.
