Technical Foundations for 765 kV Substation Engineering

The rapid expansion of 765 kV transmission infrastructure, driven by renewable integration, industrial electrification, and large scale grid modernization, requires design practices that go beyond the current industry standards. Field experience has demonstrated persistent gaps in insulation coordination, equipment specification robustness, corona performance mitigation, and electromagnetic compatibility. This project applies a research driven, utility validated approach to develop technically rigorous 765 kV substation design practices that address these gaps.

Our objective is to synthesize global operational experience, high‑fidelity modeling, and empirical testing into an integrated set of engineering recommendations that improve system performance, reduce maintenance costs, and enhance long‑term asset resilience.
