Wildlife Mitigation, Done Right, Removes One of the Top-Three Outage Categories From Your Cause Distribution.

Wildlife-caused outage events are one of the most consistent forced-outage categories on a typical Canadian distribution network. They’re predictable, recurring, and concentrated on a recognizable set of feeders and asset geometries. The hardware to stop them has existed for decades — what changes the outcome is how the program is scoped, which assets get prioritized, and how consistently the work is installed in the field.

This page documents how Canadian utilities are deploying TE/WAP polymer wildlife covers — what the operational outcomes look like, which feeder conditions warrant which programs, and how TE’s Technical Engagement & Training program supports the deployment work.

Stop the Outage Pattern That Repeats Year After Year on the Same Feeders.

Wildlife outage events follow a pattern. The same handful of feeders absorb the worst-hit count year after year, on the same exposed asset geometries — transformer bushings, deadend and line-post insulators, breaker bushings in substations, conductor and jumper sections at junction points. The pattern is so consistent that reliability planners can identify candidate assets from outage records before a field walkdown happens.

WAP polymer covers deployed across a worst-hit feeder’s exposed assets drop the wildlife-event count on that feeder to near zero — converting a recurring sustained-outage category into a maintained-asset category. Hot-stick installable means the work runs without de-energizing the feeder and without a planned outage window.

Wildlife-event outage count drops on covered feeders

Repeat events on the worst-hit assets stop after the cover deployment. The outage data tells the story before the engineering walkdown does.

CAIDI and SAIDI move on feeders where wildlife events were a top-three cause

Removing the wildlife-event category from the cause distribution converts sustained outages into prevented ones.

Storm-restoration overtime and emergency truck rolls drop

The outages that don’t happen don’t generate restoration calls — the mitigation cost is paid back through the events that never reach the dispatcher.

The pilot becomes a standardized practice

Worst-hit-feeder pilots that show measurable outcomes inside one reliability reporting cycle become defensible expansion programs across the next tier of repeat-pattern feeders.

Substation Bushing Flashover Events Are a Higher-Consequence Pattern — With Higher Mitigation Leverage.

Substation wildlife events drive a separate consequence profile from distribution-level events: typically higher customer-minutes-out per event, longer restoration cycles, and station-level reliability impact that shows up on regulator-reported metrics. The events concentrate on a recognizable set of substation apparatus geometries — transformer bushings, breaker bushings, station-class apparatus, and the equipment combinations that drive substation flashover events.

WAP substation cover configurations are engineered for those geometries directly. Substation mitigation programs are typically higher-value-per-asset investments than distribution-class cover programs, with reliability outcomes that show up on station-level metrics rather than feeder-level.

Substation forced-outage events on bushing flashover patterns drop on substations with WAP substation-class covers deployed.

Station-level reliability metrics move on substations with active wildlife mitigation programs.

Application-engineering work at the specification stage produces a defensible substation mitigation program scope — engineered per substation rather than catalog-selected.

Wildlife Mitigation Is Often the Fastest-Payback Move in a Resilience Investment Program.

Grid hardening programs frequently start as a capital-planning exercise — undergrounding, asset replacement, automation — and stall at the budget conversation. The investments that actually move reliability metrics fastest and earliest in the program are usually the smaller, faster ones: wildlife mitigation on the worst-hit feeders, substation cover deployment on the bushing geometries driving flashover events.

WAP is engineered to deploy inside a hardening program without forklift upgrades, without an extended outage window, and without specialized supply-chain procurement separate from the rest of the distribution material program. Specified through Rexel Utility, the portfolio sits inside the existing Canadian material supply chain.

Worst-hit-feeder pilot programs

Cover deployment on the three to five feeders with the highest wildlife-event count — a defensible reliability investment with measurable outcomes inside one fiscal year.

Substation wildlife mitigation

Substation-class cover deployment on the bushing geometries driving substation forced-outage events.

Feeder hardening sequencing

WAP covers deployed alongside other feeder hardening work — pole and crossarm replacement, vegetation management — as part of integrated feeder reliability programs.

Canadian climate exposure

Polymer construction engineered for Canadian climate exposure — UV, freeze-thaw, salt and contamination, thermal cycling — performs across asset design life in the operating conditions covers are specified into.

The Program That Makes WAP Cover Installation Consistent Across Crews and Territories.

Wildlife mitigation programs share a recurring operational failure mode: the right covers specified, the wrong installation practice in the field. The variance shows up across crews, contractors, and operating-centre territories — and it’s the single largest controllable factor in whether a wildlife mitigation investment delivers the operational outcome it was scoped for.

TE’s Technical Engagement & Training program is engineered to close that gap for WAP. Canadian utilities are using it in a handful of recurring ways:

Crew installation training at operating centres

Training trailer visits or instructor-led sessions delivered to crews at their own operating centres, covering hot-stick cover installation technique across the cover families.

Engineering and standards group seminars

Technical sessions delivered during specification work, covering cover family selection, voltage class considerations, and standards-compliance documentation for utility standards groups.

Wildlife mitigation program design support

Application-engineering engagement at the program-design stage — feeder asset selection, cover geometry specification, field-deployment sequencing for a worst-hit-feeder mitigation rollout.

Substation wildlife mitigation engineering support

Direct TE engineering on substation cover configurations and station-level mitigation program design — non-standard work that exceeds standard catalog selection.

What Standardizing on WAP Looks Like on the Reliability Calendar.

Standardizing on WAP through Rexel Utility produces a recognizable operational pattern across a year of reliability work. Worst-hit-feeder mitigation runs against the spring and fall windows; substation cover programs run against the substation reliability calendar; training engagements sit alongside both, scheduled to lead the field deployment. The portfolio produces the operational outcomes; the supply and engineering relationship makes the calendar deliverable.

Wildlife-event outage counts drop on feeders inside the mitigation program — typically measurable inside one reliability reporting cycle after deployment.

Substation forced-outage events drop on substations with active WAP substation-class deployments.

Crew installation practice tightens across territories. The training program produces consistent installation outcomes across crew rosters, contractor variation, and operating-centre territories.

Reliability metrics move. CAIDI and SAIDI on feeders inside the program shift in the direction the program is engineered to move them — by removing the wildlife-event category from the cause distribution.

Canadian inventory backs the deployment calendar. WAP covers are stocked across Rexel Utility’s Canadian distribution footprint — Surrey, Edmonton, Newmarket, and Quebec — so the deployment calendar is driven by program design, not by import lead times.

Frequently Asked Questions

How quickly do WAP covers reduce wildlife outage events on a feeder?

 

Covered feeders typically show a measurable drop in wildlife-event outage counts inside one reliability reporting cycle after deployment, with worst-hit-asset repeat events stopping immediately after the covers are installed. Specific outcomes depend on feeder asset count, prior event distribution, and the cover deployment scope — confirmed during program design with TE engineering.

Most utilities prioritize the three to five feeders with the highest historical wildlife-event outage count from the prior reliability reporting period. Application-engineering support through Rexel Utility helps with feeder asset selection, cover family specification per asset, and field-deployment sequencing for a defensible worst-hit-feeder pilot scope.

Substation events drive higher customer-minutes-out per event and longer restoration cycles than distribution events. WAP substation cover configurations are engineered specifically for substation apparatus geometries and typically warrant TE application engineering at the specification stage — higher-value-per-asset investments with station-level reliability outcomes.

Yes. WAP covers are engineered for hot-stick installation on energized distribution assets, with no de-energization or planned outage window required for most distribution applications. The mitigation deploys without interrupting service to customers — the standing operational advantage that makes WAP programs schedulable against normal feeder maintenance windows.

Yes. TE’s Technical Engagement & Training program covers cover installation practice across the WAP portfolio — distribution-class hot-stick installation, substation-class installation procedures, and the cover family selection considerations that go into program design. Training trailer visits and on-site demonstrations are coordinated through Rexel Utility’s specialist contact pathway.
