Knobelsdorff (KE) provided testing and commissioning services for a 135.5MWDC solar collector substation at the Spring Grove II site in Virginia. Supporting a new solar generation facility, the project required detailed coordination, technical precision and a strong understanding of utility-scale power systems to ensure the substation could be safely energized and brought online.
As part of a new solar generation development, the collector substation needed to be fully tested and commissioned prior to energization. The scope included critical infrastructure such as a 230kV SF6 breaker, main power transformer, 34.5kV vacuum breakers and SEL-based protective relays, along with associated communication and control systems.
With multiple systems requiring validation and coordination with the interconnecting utility, the project demanded a structured and thorough approach to confirm performance and readiness. PACK Power partnered with KE based on the team’s technical expertise and ability to respond quickly, helping keep the project on track during a key phase of development.
