Church Electricity Rates
A large sanctuary used ten hours a week can pay demand charges like a building used sixty. That's the load-factor trap most congregations don't see until they're already paying for it.
The demand charge problem for congregations
Most commercial utility tariffs include a demand charge — a fee based on your highest 15- or 30-minute interval of consumption during the billing period. For a house of worship, that peak almost always happens at the same moment every week: when the HVAC system races to bring a large, high-ceiling sanctuary from overnight setback to comfortable temperature before the first service.
That one Sunday-morning recovery spike sets the demand charge for the entire month. The building may sit near-idle the other 160 hours, but the utility doesn't care — the charge is set by the peak, not the average.
The fix isn't complicated. Pre-condition the sanctuary gradually over several hours rather than cold-starting it an hour before service. That spreads the load over time, lowers the peak that sets the charge, and doesn't require any capital investment — just a schedule change. For a fuller explanation of how demand charges work, see our demand charges guide.
What drives electricity use in a house of worship
HVAC — the main event
Conditioning a large sanctuary with high ceilings and poor thermal mass is expensive. The cold-start blast before Sunday service creates the demand spike that drives the monthly charge. Zoning the system so offices and classrooms don't condition the sanctuary during the week helps too — there's no reason to heat or cool 10,000 square feet when only a handful of staff are in the building.
Lighting — high ceilings, long replacement cycles
Sanctuary lighting often runs on fixtures mounted thirty or forty feet up. That height means long lamp life matters as much as efficiency — accessing a fixture requires a lift, so replacement labor is significant. LED retrofits in high-ceiling sanctuaries pay back faster than in typical commercial spaces because they reduce both the wattage and the number of times you need the lift.
Weekday operations — offices, classrooms, childcare
Congregations with active weekday programming — daycare, school, food pantry, community events — have a much better load factor than those that only open Sundays. The additional weekday consumption raises the average without raising the peak, which softens the ratio that determines how efficiently you're using your electrical capacity.
Fellowship and kitchen facilities
Commercial kitchen equipment used for fellowship meals, catering, or community programs adds load concentrated around service times. Electric ranges, dishwashers, and warming equipment all pull hard in short windows — another reason to understand how the charges on your bill actually work.
Practical steps to lower the bill
- Pre-condition gradually, don't cold-start
Start warming or cooling the sanctuary several hours before the first service, at a modest setpoint. Avoid a full-blast recovery an hour before doors open. The load stays lower; so does the demand reading.
- Zone the HVAC properly
Office and classroom zones should condition independently of the sanctuary. Running the full system to serve a few staff members on Tuesday burns money and raises your baseline unnecessarily.
- Set aggressive setback schedules
Program the thermostat to wide setbacks on empty days. A sanctuary doesn't need to stay at 70°F on a Wednesday when no one will be there until Saturday evening at the earliest.
- LED retrofits in high-ceiling fixtures
The labor to access a thirty-foot fixture with a lift is the same whether the bulb lasts two years or fifteen. LEDs cut wattage and extend replacement intervals significantly — both matter when the access is expensive.
- Compare supply quotes at renewal
In deregulated states, the supply portion of the bill is separate from utility delivery charges. Congregations often qualify for small-business rate schedules and can lock in fixed supply rates that protect the annual budget. Use our business quote form to see what's available in your area.

Church electricity questions
Why is our church's electric bill so high when we only use the building one day a week?
The culprit is load factor — the ratio of your average demand to your peak demand. A large sanctuary that sits near-idle all week but gets blasted with HVAC to reach comfortable temperature before Sunday service creates a very sharp, very high demand spike. On demand-billed utility schedules, that one spike sets a demand charge that gets applied to the entire month, regardless of how little you use the rest of the days. You're effectively paying for peak capacity you only need a few hours a week. Weekday use for offices, classrooms, or childcare actually helps by softening that ratio.
Do churches pay demand charges?
Many do, yes. Demand charges appear on most commercial utility tariffs once a meter reaches a certain size. They're calculated from your highest 15- or 30-minute interval of consumption during the billing period. For a congregation, that peak almost always happens during Sunday morning HVAC recovery — the system fighting to pull a large, high-ceiling space from overnight setback to a comfortable temperature in a short window. Pre-conditioning the sanctuary gradually over several hours, rather than a cold-start blast right before service, spreads that load and can meaningfully reduce the peak that sets the charge. See our guide to demand charges for a fuller explanation.
What rate class should our congregation be on?
Check the rate classification on your current utility bill — it's usually a short code like GS (General Service), SC (Small Commercial), or similar. Many smaller congregations qualify for small-commercial or even small-business rate schedules, which carry lower per-kWh rates or more favorable demand charge structures than large-commercial tariffs. If your meter was defaulted onto a large-commercial schedule when the building was built, you may be overpaying for your actual usage profile. Contact your utility's business customer service line to ask whether a reclassification makes sense for your load. In deregulated states, the rate class on the utility (delivery) side is separate from your supply contract — both matter.
Should we lock in a fixed rate or stay on a variable rate?
Fixed supply rates suit most congregations well. Church budgets are typically set annually by a board or council, and budget predictability matters more than the theoretical upside of a variable rate. A fixed-rate supply contract lets you know exactly what you'll pay per kilowatt-hour for the contract term, which makes budget planning straightforward. Variable rates can drop when wholesale energy prices fall, but they also spike — sometimes significantly — during extreme weather. For a nonprofit operating on a tight budget, that exposure is hard to absorb.
When is the right time for a congregation to shop its electricity supply?
In deregulated states (Texas, Ohio, Pennsylvania, Massachusetts, New Jersey, and Washington DC), your congregation can choose its electricity supplier separately from the utility that delivers power. The best time to shop is 60–90 days before your current contract expires, which gives competing suppliers time to quote and you time to compare. If you're on a month-to-month or default utility supply rate, you can shop anytime. Compare all-in quotes — the cents-per-kWh rate, any monthly fees, and the contract length — before signing.
