Mid-Year Electrical Reliability Check: Is Your Facility Ready for the Second Half of the Year?

June is a natural checkpoint for facility managers to evaluate the health of their electrical infrastructure. By mid-year, most facilities have experienced some combination of equipment additions, relocations, tenant improvements, production changes, and shifting maintenance priorities.

While these changes are often necessary to support operations, they can gradually alter the electrical system without triggering a formal review. Drawings may no longer reflect field conditions, maintenance items may be deferred, and new loads may be added without fully assessing their impact on the existing distribution system.

At the same time, summer brings increased electrical demand. Higher cooling loads, longer operating hours, and increased energy consumption place additional stress on electrical infrastructure, making this an ideal time to identify gaps, update documentation, and address outstanding maintenance items before they become larger operational issues.

The Electrical System Challenge

Electrical infrastructure behaves differently than most other building systems because many problems develop with little or no visible warning.

A failing HVAC unit often becomes noisy or loses performance. Plumbing problems typically reveal themselves through leaks or water damage. Electrical systems can appear to be operating normally while risk accumulates in the background. Loose connections generate heat that cannot be seen during normal operation. Aging breakers may continue functioning long after maintenance is overdue. Documentation becomes outdated as modifications occur throughout the facility.

As a result, electrical reliability issues often emerge during periods of peak demand, when systems are under the greatest stress. Facilities with aging infrastructure, deferred maintenance, unresolved deficiencies, or outdated documentation are vulnerable. That’s why electrical maintenance relies heavily on inspections, infrared scanning, testing, engineering reviews, and documentation management. The absence of a visible problem doesn’t necessarily indicate the absence of risk.

A Mid-Year Electrical Reliability Checklist

Before the second half of the year gets underway, facility managers should consider reviewing the following:

Documentation and System Changes

• Review and update one-line diagrams and electrical drawings
• Document equipment additions, relocations, and system modifications completed this year
• Review moves, adds, and changes completed during the first half of the year
• Verify electrical equipment labels remain accurate and legible

Maintenance and Inspection Activities

• Complete or schedule annual infrared (IR) scanning if not already performed
• Review and address outstanding IR scan findings
• Review breaker maintenance and switchgear service records
• Inspect electrical rooms for housekeeping, ventilation, and accessibility concerns

Reliability and Risk Reduction

• Address recurring breaker trips, nuisance outages, or unresolved electrical issues
• Prioritize deferred electrical maintenance items
• Test and maintain backup power systems and generators
• Identify aging equipment that may require additional inspection, repair, or replacement planning

The Value of a Mid-Year Electrical Reliability Review

Facilities that avoid unexpected outages are rarely the ones reacting the fastest. They’re often the ones that regularly evaluate their infrastructure, update documentation, address maintenance issues, and identify emerging risks before they become operational problems.

Mid-year provides an ideal opportunity to pause, assess, and ensure electrical systems are prepared for both peak summer demand and the second half of the year.

The question is simple: Does your electrical infrastructure accurately reflect the way your facility operates today? If the answer isn’t clear, now is the right time for a mid-year electrical reliability review.
