A practical method for estimating indoor farm energy demand by separating connected load from real operating hours and climate duty.
Peak power describes maximum connected demand at a moment in time. Energy use is measured over time. A useful monthly estimate models each electrical load separately and applies expected operating hours and duty factor.
Grow lighting normally follows a crop-specific photoperiod. Its energy contribution can be estimated from lighting power, hours per day and operating days. Crop plan and dimming strategy can materially change the result.
HVAC and dehumidification are affected by ambient temperature, humidity, insulation, crop transpiration, fresh-air strategy and door opening. Identical growing systems can therefore have different energy profiles in different climates.
Irrigation pumps, dosing equipment, circulation fans, sensors, controllers and other auxiliary loads may be smaller than lighting or HVAC but still operate on their own schedules. Include them separately.
A practical estimate is the sum of each load in kW multiplied by operating hours, days and a realistic duty factor. Use project-specific measured values where available, then apply the local electricity tariff.
