Your Business and JPS
Every dollar of usage you avoid is a dollar that stays in your business.
Efficiency is not about running less. It is about running the same operation on fewer kilowatt-hours. This page shows you where your usage concentrates, when to shift it, and what to check before you spend on new equipment.
Section 01 — Equipment
Efficiency by equipment category
Most small business usage is not spread evenly. It concentrates in a handful of machines that run long hours, cycle constantly, or move heat. Start where the load is.
Section 02 — Timing
Time-of-Use, in plain language
A standard rate treats every kilowatt-hour the same, whatever hour you use it. A Time-of-Use rate does not. It prices the hour as well as the energy, because the electricity system itself works harder at some hours than others.
A rate that reads the clock
Under Time-of-Use, the day is divided into windows. Energy used inside a peak window is priced differently from energy used off-peak. Your meter records not just how much, but when.
An interval meter does the counting
Time-of-Use requires a meter capable of recording usage in intervals. Your monthly statement then reflects the split across windows rather than a single undifferentiated total.
Businesses with movable load
Time-of-Use rewards flexibility. If you can move a laundry cycle, a batch bake, a pressure wash, or a charging session outside peak hours without hurting service, you have something to work with. If your load is fixed to trading hours, the gain is smaller.

Three moves that matter most for you
The highest-impact efficiency move depends on what your business actually runs. Find yourself below.
Section 04 — Equipment Decisions
The inverter question
Inverter appliances cost more on the showroom floor. Whether they earn that difference back depends on how you run them. Here is the mechanism, the math, and the myths.
A conventional compressor or motor has two states. Full on, and off. To hold a fridge at temperature, it slams to maximum, overshoots, cuts out, drifts, and slams on again. Every restart draws a surge far above running draw.
An inverter appliance varies the frequency supplied to the motor, so it can run at twenty percent, at sixty percent, at whatever the load actually calls for. It reaches temperature and then idles there instead of cycling. Fewer surges, less overshoot, less energy spent correcting itself.
This is why the gain is largest in equipment that runs long hours against a stable target: refrigeration and air conditioning. It is smallest in equipment that runs briefly and hard, then stops.
The math, honestly
Inverter equipment carries a higher purchase price. The saving arrives as reduced usage, month after month, for the life of the unit. The decision turns on three variables: how many hours a day the unit runs, how many years you expect to keep it, and how much more the inverter model costs.
A unit running twelve hours a day pays back far faster than the same unit running three. If your air conditioner runs through every trading hour, the inverter case is strong. If it runs an hour before closing, it is weak. Do this arithmetic on your own hours before you buy, not on a general rule.
What to check on the showroom floor
- Confirm the word inverter appears on the unit and in the specification sheet, not only in the store's signage.
- Read the energy label. Compare annual consumption between models of the same capacity, not between different capacities.
- Size the unit to the room. An oversized inverter AC cycles like a conventional one and loses most of its advantage.
- Ask what the compressor warranty covers and for how long. The compressor is the part you are paying extra for.
- Confirm parts and service are available on-island for that brand before you commit.
Section 05 — Estimator
Estimate your monthly usage
Pick your business type, tick what you run, set your hours. You will get an estimated monthly range in kilowatt-hours and the two changes most likely to move it. Your selections are saved on this device.

Section 06 — Generation
Going solar, and how net billing works
Solar makes sense for a business whose usage is already efficient and whose daytime load is high. That order matters. A system sized to carry wasteful equipment is a more expensive system than the one you needed. Reduce first, then generate.
If your business draws its heaviest load while the sun is up, a retailer, a salon, a workshop, you are the natural candidate. If your load is concentrated after dark, the case weakens unless storage enters the picture.
Under net billing, the energy your system produces is used on site first. Whatever you do not consume flows out to the grid and is credited to your account. Energy you draw when your system is not producing is supplied by the grid as normal. Your system must be approved and interconnected before it operates in parallel with the grid.
