Laundromats energy planning: load, costs and contract choices

Start with the actual operating profile

Laundry utility costs arise from water heating, drying, motors and customer activity. Electricity and gas should be modeled separately with machine turns and equipment fuel type. A per-square-foot comparison can hide changes in machine capacity or dryer utilization.

Map electricity and gas separately

The electrical review should identify washer motors, lighting, ventilation and electric drying where installed. For natural gas, establish whether the site uses dryers and water heating where gas-fired. Equipment fuel and meter ownership matter: a tenant may pay only part of the building’s utility cost.

For the cost review, keep combined energy cost per wash-and-dry cycle separate from a supplier energy rate. The operating metric includes the business’s activity and chosen cost boundary; the supply price measures a different part of the decision.

Translate operating plans into contract questions

Record machine turns, weekend peaks and any commercial laundry work.

Replacing gas dryers with electric models changes more than the supplier rate; check service capacity and demand.

Ask how the forecast and planned changes are handled in volume, assignment or closure terms before approving a contract.

Keep procurement and efficiency evidence separate

Review maintenance, exhaust and hot-water controls with equipment specialists.

For internal monitoring, consider combined energy cost per wash-and-dry cycle. Use a consistent definition and compare similar periods. This operating metric is a management tool, not a universal benchmark or an ENERGY STAR score.

The verification record should connect the result to machine inventory. Changes in that activity can explain a bill movement even when the supply price is unchanged.

Records for a useful review

Alongside twelve months of bills and the current agreement, prepare the records that explain laundromats operations:

• Machine inventory.
• Turns.
• Dryer fuel.
• Water-heating specifications.

Hypothetical machine-mix normalization

Hypothetical: a laundromat records 4,000 small-machine turns and 1,000 larger-machine turns monthly. Management defines one larger turn as two small-load equivalents for an internal worksheet, producing 6,000 equivalent loads. With $3,600 of energy spending, the ratio is $0.60 per equivalent load, compared with $0.72 per unweighted machine turn. The weighting is an explicit assumption, not a measured energy equivalence.

Retain machine capacity, program and dryer-use records before comparing periods. Keep electricity and gas separate, and do not assume a larger washer consumes exactly twice the energy. Equipment replacement or fuel switching should update the purchasing forecast and receive service-capacity and manufacturer review independently from the cost-ratio calculation.
