How much electricity do retail stores use?

CBECS 2018 puts retail buildings (other than malls) at about 13.7 kWh per square foot per year (median 9.0).

Illustrative site	Annual use	Est. peak demand	Est. capacity tag	Capacity cost at 2026/27 price	Value of 0.5¢/kWh
3,000 ft²	41,100 kWh	10 kW	9 kW	$1,065/yr (≈2.6¢/kWh)	$206/yr
10,000 ft²	137,000 kWh	35 kW	30 kW	$3,549/yr (≈2.6¢/kWh)	$685/yr
40,000 ft²	548,000 kWh	139 kW	118 kW	$14,197/yr (≈2.6¢/kWh)	$2,740/yr

How these numbers are built: annual use = 13.7 kWh/ft² (EIA CBECS 2018 Table C14, retail (other than mall) (mean; median 9.0)). Peak demand assumes a 45% load factor; the capacity tag assumes 85% of that peak falls in the grid's summer peak hours. Capacity cost uses PJM's 2026/27 clearing price of $329.17/MW-day (about $120 per kW-year) before utility scaling factors. These are illustrations for sizing a decision — your own bills and interval data are what suppliers price.

Where the electricity goes

Lighting and ventilation are about 25% each of retail electricity in CBECS, followed by cooling (13%) and refrigeration (7%).

When the load peaks — and why that matters for price

Median retail operating hours are 55 a week, with peaks on summer afternoons and holiday-season evenings when lighting, HVAC and door traffic coincide.

In Ohio's PJM market, the capacity part of your generation cost is set by how much you use during the grid's few highest summer peak hours. With a 45% load factor and about 85% of the site peak landing in those hours, capacity alone works out to roughly 2.6¢ per kWh at the 2026/27 price of $329.17/MW-day — compared with about 0.2¢ at the 2024/25 price of $28.92. That jump, not the energy price, explains most of the 2025–2026 increase in Ohio business electricity bills.

How retail stores in Ohio buy electricity

Single stores are small-commercial accounts; chains typically buy all Ohio locations together with one supplier and a master agreement, splitting price by utility territory.

If you…	Usually consider
need a fixed monthly budget	a 12–36 month fixed price with capacity included (fixed vs variable)
can move load away from summer peak hours	a product that passes capacity through at cost, so reducing your capacity tag lowers your bill
use more than 700,000 kWh a year at a site	an interval-data RFP, block-and-index structures, and HB 15's behind-the-meter options
are 700,000 kWh a year or less and never chose a supplier	first check whether you're already in a community aggregation program

Ohio rules that affect this industry

Stores in shopping centers often have their own meters but pay common-area charges through the landlord; only your own meter can be shopped.
Supplier choice applies to customers of AEP Ohio, Duke Energy Ohio, AES Ohio, Ohio Edison, The Illuminating Company and Toledo Edison. Municipal-utility and electric-cooperative customers generally can't choose a supplier.
Ohio does not charge sales tax on electricity; the per-kWh excise tax does appear on bills.
As of 2026, Ohio's utilities do not offer general business efficiency rebates, so upgrades must pay back on bill savings (plus any federal tax treatment).
Under HB 15 (effective August 14, 2025), suppliers must send two notices before a fixed-rate contract rolls to a variable rate — but only to accounts with demand of 25 kW or less. Larger sites should track their own expiration dates.

Ways retail stores cut electricity costs

Convert sales-floor and sign lighting to LED on astronomical time clocks.
Keep entry vestibules and door closers working; open doors drive HVAC load.
Set rooftop-unit schedules to store hours and lock thermostats.
For chains, standardize settings and compare every store’s kWh per square foot.

FAQ

How much electricity does a retail store use?

At CBECS’s 13.7 kWh/ft², a 10,000 ft² store would use roughly 137,000 kWh a year.

Can a chain buy electricity for all its Ohio stores at once?

Yes — a portfolio contract is common; prices are usually set per utility territory.

Is lighting still worth upgrading?

Lighting is about a quarter of retail electricity in CBECS, so LED and controls remain one of the fastest paybacks.

Operating evidence for the next contract

For retail stores, an electricity quote should reflect the actual operation rather than a generic business category. Give the reviewer the opening schedule, continuously required systems, planned equipment changes and the responsible legal customer. A national building benchmark can frame a question, but cannot prove the usage or saving at your facility.

Evidence to review	Decision it supports
Current operating schedule and required service levels	Identify whether the quoted load shape represents the next term, rather than last year’s business
Equipment and controls associated with retail store operations	Separate a procurement question from an engineering or maintenance question
A committed expansion, closure or tenant/ownership change	Review usage tolerance, assignment and site add/delete rights before signing
Written supply inclusions and exclusions	Distinguish an energy-only offer from a product that includes capacity or other components

Separate safe operating changes from price decisions

Use an appropriate facility specialist to validate technical changes. For chains, standardize settings and compare every store’s kWh per square foot. Treat that as a potential review item, not a guaranteed saving or permission to alter safety-critical settings. Medical, food, process and temperature requirements take precedence over an energy target.

Retain a base case without assumed rebates or unapproved tax benefits. If a project materially changes electricity use, ask the supplier how it affects the contract rather than silently carrying the old consumption profile forward. A lower supply price and reduced consumption are separate effects and should not be counted twice.

Keep the bid review practical

Compare at least the proposed start date, included components, monthly fees, renewal clause, exit rules and the treatment of expected load changes. Ask who is responsible for enrollment and what happens if a meter cannot switch on the expected date. An adviser should be able to explain why staying on the current arrangement may be appropriate.
