After repeated outages and signs of structural degradation, a major utility in the Western U.S. launched a multi-year grid modernization program. The initiative aimed to improve system reliability, expand capacity, and address aging infrastructure across the service territory.
As part of this effort, the project scope included upgrading 60 kV transmission lines to 120 kV. In addition, it involved rebuilding several substations to meet both current and future demands. ReeshaTech was engaged early to lead business case development, scope definition, budget forecasting, scheduling, permitting, and stakeholder coordination. Consequently, this established a strong foundation for successful execution.
Our team delivered a broad range of engineering services to support the utility’s modernization goals. Specifically, on the transmission side, we managed end-to-end line design. This work included GIS mapping, topographic surveys, land acquisition, easement negotiation, rerouting plans, and final structure placement.
To ensure compliance with modern standards, our engineers performed detailed pole loading analysis. These studies accounted for both communication and distribution underbuilds to guarantee safety and structural reliability.
Moreover, we supported the rebuild of five substations. Our scope included specifying high-voltage equipment, switchgear, transformers, and protective relaying systems. Additionally, we handled procurement of long-lead items and ensured on-time delivery to match construction milestones. Each rebuild improved system redundancy and allowed for seamless integration with upgraded transmission lines.
During construction, ReeshaTech played a critical role in execution. We coordinated with vendors and contractors, provided field engineering oversight, performed safety and compliance inspections, and managed planned outages. As a result, our integrated approach helped control costs, reduce schedule risk, and ensure high-quality results.
Ultimately, the outcome was a modernized, resilient transmission network ready to support present and future load demands. This project highlights ReeshaTech’s ability to deliver turnkey utility infrastructure solutions—managing the full lifecycle from planning to energization with precision, reliability, and adaptability.
