Most exposed

Where AI can do more

Routine, digitized, and highly repeatable tasks face the greatest pressure.

  1. Run signal quality and connectivity tests for individual cables, and record results.67
  2. Disconnect voltage regulators, bolts, and screws, and connect replacement regulators to high-voltage lines.67
  3. Maintain inventories of spare parts for all equipment, requisitioning parts as necessary.65
  4. Test insulators and bushings of equipment by inducing voltage across insulation, testing current, and calculating insulation loss.65
Hardest to automate

Where people still matter

These tasks score lowest on automation feasibility—physical presence, judgement, accountability and real-world variability all resist end-to-end automation.

Beyond AI capability

Adoption and labour-market outlook

Structural factors are kept separate from raw capability so you can see what actually resists automation. Adoption pressure and labour-market resilience are still provisional models—25% of this occupation’s replacement-risk weight rests on them.
