Choosing backup power

What to prepare for a generator site assessment

The short answer

Bring a list of the systems you want protected, any future changes to the property and information about an existing generator. Make access arrangements in advance. You do not need to measure electrical loads or open equipment yourself to have a productive first visit.

General guidance, not installation, repair, engineering or legal instructions. Confirm equipment-specific and current local requirements with the appropriate professional.

Describe the result you want

Explain what would be most disruptive without electricity: losing heat, water, refrigeration, business systems or the ability to work from home. Include who lives at or uses the property and whether it is sometimes unoccupied. These details help turn a broad request for backup power into a specific discussion of priorities.

Bring the property questions early

Share known renovation plans, available surveys, association requirements and concerns about views, landscaping or neighbors. Point out past flooding or drainage problems without entering unsafe areas. If fuel service is uncertain, say so; there is no need to guess the gas meter or tank capacity before a professional assessment.

Make access and decisions straightforward

Identify the owner or authorized decision-maker and any property manager who should receive the proposal. Confirm how the team will access the relevant areas and whether pets or locked gates require arrangements. Sensitive entry codes should be shared through an agreed private method, not placed in a public review or general website message.

Put it into practice

Your site-visit folder

  • A must-have and nice-to-have list of backed-up systems.
  • Existing equipment model details and service records, if available.
  • A survey or site plan you already have—do not commission one without asking.
  • Questions about placement, future additions, budget and timing.

Is a calculator result enough for an equipment order?

No. An online estimate is a conversation starter. The assessment still needs to consider real equipment, starting demand, fuel, placement and project requirements before a final selection or installation proposal is confirmed.
