Knowledge Loss in Utilities and Energy: An Aging, Safety-Critical Workforce

Keeping the lights on runs on people who have spent careers learning how the system actually behaves. The operator who knows how a substation responds under load, the lineworker who can read a fault, the plant veteran who knows the quirks of equipment older than they are: this is deep operational knowledge, safety-critical and largely undocumented. And the utilities sector is aging faster than any other.

A wave of replacements, and a knowledge gap underneath it

The hiring need is enormous: energy employers are projected to need roughly 15 million replacement workers between 2025 and 2035 as the current workforce ages out (Brookings, cited by the Center for Energy Workforce Development). But hiring a replacement is not the same as replacing the knowledge. A new operator can be trained on procedures in months; the judgment a 30-year veteran brings takes far longer, and much of it was never written down to train from.

Why utility knowledge is high-exposure

• It is tacit and system-specific. Much of the expertise is about how this grid, this plant, this equipment behaves, learned by working it for years.
• The stakes are safety and reliability. A knowledge gap can mean an outage, an equipment failure, or a safety incident, not just a slow week.
• Apprenticeships are long. Skilled trades and operations roles take years to develop, so a retiring expert who leaves without transferring what they know creates a gap that cannot be filled quickly.

A procedure tells a new operator the steps. A retiring one knows what the system does when the steps are not enough. That is the knowledge worth capturing.

What to capture before a retirement

The priority is the operational judgment a successor cannot get from a manual: how the veteran diagnoses a recurring fault, the signs they watch for before something fails, the institutional knowledge about specific equipment and past incidents. Captured through a structured session, this becomes something the next operator can actually use.

1. Map the roles where one person is the only one who can keep a system, plant, or process running. A free Knowledge Risk Assessment produces that single-point-of-failure view.
2. Capture those experts first, through guided conversation, well ahead of their retirement date.
3. Turn each session into a successor briefing and a risk view a crew lead can hand to the next operator. See how to run the capture.

TacitTalks runs the capture and produces those artifacts automatically, and for a single critical expert the Continuity Pack handles it for a flat fee. See also the overview of knowledge loss by industry.
