A geothermal system can be part of a battery or generator plan when the exact compressor, blower, loop pumps, controls and backup-heat sequence are known. The design must also account for well pumps on open-loop systems and any domestic-water, sump, refrigeration or other household loads expected to operate at the same time.
BUILD THE LOAD LIST
Start with equipment data and the operating sequence.
A resilience calculation should use the final equipment electrical data, not a generic watts-per-ton rule. Staging and controls matter because the compressor, blower, pumps and auxiliary heat may not all operate together under every condition.
- Exact geothermal compressor and indoor blower requirements
- Closed-loop circulators or open-loop well-pump demand
- Electric auxiliary heat stages and emergency-heat behavior
- Thermostat, control, condensate and zone equipment
- Other essential household loads and allowed simultaneous operation
STORED ELECTRICITY
Battery planning
A battery system needs adequate inverter output for permitted starting and running loads, plus usable stored energy for the target duration. Load shedding can be more valuable than simply adding capacity.
- Required heating mode during an outage
- Maximum simultaneous power
- Desired operating hours
- Recharge source and winter conditions
- Essential-load panel or controllable circuits
- Compressor and pump restart behavior
- Auxiliary-heat lockout
- Transfer and islanding equipment
ON-SITE GENERATION
Generator planning
A generator must support the approved starting and continuous loads while maintaining acceptable voltage and frequency. Fuel type, storage, cold-weather output, placement, exhaust, transfer equipment and maintenance are part of the design.
Load-management controls may prevent large appliances or auxiliary heat from operating simultaneously. The homeowner should know which loads are automatic, delayed, shed or unavailable.
THE LARGE LOAD TO CONTROL
Electric auxiliary heat can change the entire backup design.
Resistance heat can add substantial demand compared with compressor-only operation. A resilience plan may intentionally limit or lock out auxiliary stages during an outage, accept reduced indoor temperature, prioritize a smaller conditioned area or use an approved fuel-based backup strategy. Those choices must be explicit and commissioned.

Choose the outage objective before the equipment.
Protect the basics
Refrigeration, lighting, communications, sump or well needs and a defined heating mode—not every normal household load.
Heat with limits
Operate geothermal under planned staging or temperature limits while shedding auxiliary heat and selected appliances.
Document concurrency
Identify which large loads may run together, how long they must run and what the transfer or energy-management system will control.
CURRENT LITE WORKFLOW
The site records the outage priority—not a battery or generator size.
The quote workflow carries the customer’s resilience preference into the ServiceTitan summary. It does not price electrical circuits, service upgrades, batteries, generators, transfer equipment or load-management controls. Those remain a separate verified electrical scope.

What turns the goal into a resilience design.
- Finalize geothermal equipment, pumps, auxiliary heat and control sequence.
- Measure or document starting and continuous electrical requirements.
- List essential loads, simultaneous loads and desired runtime.
- Inspect service, panels, grounding, transfer location and circuit routing.
- Define load shedding, restart delays and auxiliary-heat lockouts.
- Confirm battery environment or generator fuel, placement, exhaust and maintenance.
- Commission normal, outage, recovery and emergency modes with the homeowner.
