Grid Modernization Is Colliding With a Retiring Protection Engineering Workforce
Utilities are funding the largest substation build-out in decades right as the relay and protection engineers who know legacy systems head into retirement.

Three demand drivers converging at once
Interconnection backlogs for solar, wind, and battery storage projects are forcing utilities to build and upgrade substations faster than their internal engineering staff can process the work. At the same time, decades-old transmission infrastructure is reaching end of life, and utilities are running parallel replacement programs. Layer on federal and state grid resilience funding and the substation project count has outpaced anything utilities have staffed for in a generation.
Relay and protection engineering is the discipline most exposed. It is a narrow specialty that takes years to develop, and it has historically attracted fewer new entrants than more visible fields like renewable generation design.
The demographic problem is real and it is close
A meaningful share of experienced protection engineers at investor-owned and municipal utilities are within five to ten years of retirement. These are the people who understand legacy relay schemes well enough to modernize them without introducing a misoperation, and their institutional knowledge does not transfer through documentation alone - it transfers through years of working alongside them.
| Function | Demand trend | Talent constraint |
|---|---|---|
| Protection & relay engineering | Sharp increase | Severe - aging workforce, narrow specialty |
| Substation design engineering | Increase | Moderate |
| Field commissioning & testing | Sharp increase | High - travel-heavy, limited pool |
| SCADA/RTU integration | Increase | Moderate to high |
Why utilities can't just hire their way out
- Protection engineering requires familiarity with equipment vintages spanning 40+ years on a single system
- NERC compliance and testing documentation demands are heavier than they were a decade ago, adding hours per project without adding staff
- Many utilities have shrunk internal engineering headcount over the last two decades and now rely on contract and consulting support for peak load
- Interconnection studies compete for the same protection engineering talent that substation build programs need
Field commissioning is the other pinch point
Substation commissioning and testing work is rotational and travel-heavy by nature - crews move from site to site as programs progress. The pool of engineers and technicians willing to sustain that lifestyle for multi-year programs has not grown with the project pipeline, and per diem and travel premiums have risen accordingly.
What a workable staffing model looks like
- Blend internal senior staff with contract protection engineers for knowledge continuity, not just headcount
- Start succession planning for protection roles at least two years ahead of a known retirement date
- Build standing relationships with firms that maintain a bench of relay-qualified engineers rather than posting reactive requisitions
- Budget commissioning field labor with realistic travel premiums rather than assuming local hires will absorb rotational demand
None of this is exotic. It is workforce planning applied to a discipline that utilities have historically under-invested in because outages were rare enough to make the risk feel abstract. That risk is no longer abstract given the current build volume.
Summary
Key takeaways
- Interconnection backlogs, aging infrastructure, and resilience funding are driving substation project counts to multi-decade highs
- Protection and relay engineering skews toward an aging workforce with a narrow pipeline of new entrants
- Field commissioning for substations is rotational and travel-heavy, and the willing labor pool has not scaled with project volume
- Pairing retiring engineers with contract staff for an 18-24 month transfer window measurably reduces commissioning delays
