Distribution facilities get treated as simple loads. Big box, lights, some conveyor, done. That assumption is what leaves money in the contract, because the modern warehouse has three distinct load behaviours and only one of them is flat.

Three loads in one building

Ambient conditioning and lighting is the flat part, and the part everyone prices. Predictable, cheap to serve, and not where the negotiation should focus.

Refrigeration, where present, is the dominant load and it is weather-coupled. A cold chain facility in July behaves nothing like the same building in March, and a contract written off an annual average will be wrong in both directions.

Automation and materials handling is the newest variable. Conveyor, sortation, automated storage and retrieval, and increasingly battery charging for electric forklifts and autonomous units. This load is peaky, it tracks throughput rather than the calendar, and in a facility built out over several years it often was never re-baselined.

Forklift charging is the one people miss

The shift from propane to electric lift trucks moved a fuel cost onto the electricity bill, and specifically onto the demand charge. A bank of chargers coming on together at shift change is exactly the coincident peak that sets a monthly demand number.

It is also one of the easiest to manage. Opportunity charging, staggered start times, or simply moving the bulk charge outside the facility peak window are operational changes rather than capital ones.

Seasonality cuts both ways

Distribution volume is seasonal in most sectors, and the seasonality is known in advance. That is unusual and it is an advantage at contract time, because a supplier pricing a load they can predict prices it more cheaply than one they cannot.

Bandwidth clauses matter here. A fixed contract with tight swing provisions can penalise you for the peak season you told them about. Read the tolerance bands against your own volume forecast rather than against an annual average.

The multi-site question

Most distribution operators run several facilities, often across state lines and therefore across regulatory regimes. The same rules apply as in retail: aggregate the sites in markets with retail choice into a single bid, handle the regulated sites as a tariff and efficiency exercise, and stagger contract end dates so the whole estate does not reprice at once.

What to bring to a bid

• Twelve to twenty-four months of interval data per facility, not monthly summaries.
• A volume forecast by season, since you have one and it improves your pricing.
• A clear statement of which sites are refrigerated and which are ambient. They are different books.
• Any planned automation build-out, because it changes the shape you are asking to be priced.
• The list of which sites sit in deregulated markets.

Where to start

Find the interval that set your demand charge last month at your largest facility. In a distribution building it is usually shift change, refrigeration recovery after a dock door has been open, or a charging bank. All three are manageable, and none require a capital project to address.
