Commercial electricity for cold storage

Nearly flat around the clock. Very little peak to attack, which is why supply price and contract timing dominate this profile rather than demand management.

Illustrative shape, not measured data. It shows the pattern this kind of operation tends to follow, which is why its bill behaves the way it does. Your real profile comes from your own interval data, and it is the only version that can produce a number.

What the federal building survey says

In 2018 the U.S. Energy Information Administration surveyed 6,436 commercial buildings and recorded the electricity each used. These are the surveyed buildings that match cold storage, in kWh per square foot per year. Each is a whole building classed by what fills the most of it, so a single tenant space inside a larger building can use more or less.

Survey year 2018, so this is the usage pattern, not a forecast. Prices here are today's: the US average commercial price for the 12 months to the latest EIA month. The cost estimator does the same for your own floor area and state.

What drives the load

• Compressors and condensers
• Evaporator fans
• Defrost cycles
• Dock door management and infiltration
• Lighting

The trap this industry falls into

A high load factor means supply price and contract structure carry most of the controllable cost, which is the opposite of the restaurant case. Cold storage is one of the few commercial profiles where a supply contract genuinely is the main event — and where a poorly timed renewal is expensive.

What to actually do

1. Treat contract timing as a primary risk, not an afterthought
2. Review defrost scheduling against the demand window
3. Check condenser fouling and head pressure control
4. Evaluate whether interval data supports a shaped or block product

Which half of the bill to attack

A commercial bill splits into supply, which a competitive supplier can price where a competitive market exists, and delivery, demand, fixed charges and riders, which stay regulated whichever supplier you use. Load factor decides which half is worth your attention, and for cold storage the answer is usually clear.

At a high load factor, consumption is steady and there is comparatively little peak to attack. That pushes the controllable cost toward the supply side: the rate, the contract structure and above all the timing of the renewal. For an operation like this, a contract that expires unmanaged is usually the most expensive single event in the year.

That does not make the regulated half irrelevant — rate schedule fit and billing accuracy still apply — but it does mean the sequence is different. Get the contract calendar right first.

The mechanics behind this: load factor, demand charges and rate schedule fit.

What we need to give you a real answer

• 24 months of bills if available
• Interval data
• Contract expiry and current structure
• Refrigeration system type and control strategy

The item that most often turns a vague conversation into a specific finding is twelve months of peak kW. A single bill shows what you paid; twelve months of demand readings show the shape that caused it, and the shape is where the recoverable money is.
