The parallels between the 5G rollout and today's grid modernization portfolios are not superficial. Both are massive, simultaneous, multi-vendor deployments running across geographies and regulatory environments at once. Both depend on coordinating infrastructure, technology, and stakeholder interests that do not naturally align. And both are governed, too often, as collections of individual projects rather than as portfolios that share dependencies, risks, and constraints.

That last distinction is where the lesson lives. The 5G programs that struggled were rarely undone by technology. They were undone by governance that could not hold the whole portfolio in view at once — that managed each deployment locally while the systemic risks accumulated between them, unowned.

The portfolio, not the project

Grid modernization is now at the same inflection point. The industry is standing up AMI deployments, DERMS implementations, EV integration, storage programs, and transmission investment — frequently as separate initiatives with separate governance, separate reporting, and separate vendors. The dependencies between them are real, but the governance that would surface those dependencies often does not exist.

The 5G experience is a warning worth heeding: when portfolio-level risks are managed only at the project level, the failures emerge exactly at the seams no single project owns. The utilities that treat grid modernization as a governed portfolio — rather than a set of parallel projects that happen to share a balance sheet — will avoid the coordination failures that defined the harder chapters of the telecom buildout.
