Example Case Study — How a Supermarket Reduced Its Energy Bill

Energy costs are one of the largest controllable expenses for many small and mid-sized businesses. To show what’s possible, here’s an example case study illustrating how an independent supermarket could reduce costs through utility bill analysis, refrigeration optimization, and small operational changes. Real results will vary, but the principles apply broadly across energy-intensive businesses.

Independent Supermarket — Cutting Peak Demand

Challenge:

A regional supermarket was seeing steadily rising electricity costs, even though sales and store hours had not changed. Peak demand charges were driving most of the increase, and refrigeration loads made up a significant share of total usage.

Approach:

Conducted a utility bill analysis to confirm how demand charges were calculated.
Reviewed interval data and identified stacking peaks from refrigeration cycles overlapping with HVAC loads.
Implemented small scheduling adjustments and optimized refrigeration setpoints without compromising food safety.

Reduction 19% in peak kW within 45 days

Reduction 12% Total Bill

Monthly $2000+ Savings

Even without new equipment, supermarkets and grocery stores can achieve meaningful savings by addressing demand charges and optimizing how major loads operate together.

Most small and mid-sized businesses overpay for electricity without realizing it. The good news is that savings opportunities often show up quickly — and they don’t always require new equipment. You can start working with us for free to find savings.
