Verdantas provided engineering services for a utility-scale solar photovoltaic (PV) and battery energy storage system (BESS) project, supporting the design of a 230 kV generation tie (Gen-Tie) transmission line, substation, and associated collection systems. The project required coordination across multiple engineering disciplines to support reliable interconnection with the regional utility grid.

The scope included civil, structural, and electrical design for the PV array, substation, and medium voltage collection system. This involved development of cable routing, foundation layouts, grounding systems, and protection and control designs to support system performance and reliability.

The project presented several complexities, including evolving design requirements as additional equipment was incorporated to improve system efficiency. The site was also designed to accommodate multiple utility off-takers, requiring adjustments to metering and protection systems as well as substation configuration.

Additional challenges included multiple roadway crossings and compliance with underground installation requirements, along with seismic considerations due to the project’s location. Verdantas addressed these challenges through coordinated design efforts, advanced modeling, and optimization strategies to support constructability and long-term system performance.
