The 15-minute interval that sets your bill
Why cutting total usage doesn't lower your bill — and what demand charges actually measure.

You cut consumption. So why didn't the bill go down?
Because for most industrial facilities, 30–70% of the electric bill is demand charges — set by your single worst 15-minute interval, not your total usage. We engineer both sides down: staggered startups, load management, peak shaving, and turnkey system upgrades. And if a project won't pay for itself, we'll tell you. We do not sell what we would not buy.
How the bill actually works
Two charges, one bill — and only one of them cares how hard you tried
Consumption is what you used. Demand is the worst 15 minutes you had all month — and on most industrial rate schedules, it's the bigger number.
Consumption charges
What most facilities focus on
- Billed on total kWh used across the whole month
- Improves gradually as equipment gets more efficient
- Rewards steady, spread-out usage
- Cutting it alone often barely moves the total bill
Demand charges
What's actually driving the number
- Billed on your single highest 15-minute interval of the month, in kW
- One bad startup sequence sets the charge for the next 30 days
- Typically 30–70% of the total industrial electric bill
- Falls fast when peaks are staggered, shaved, or shifted
The four levers
We work both sides of the meter
Consumption efficiency helps. Controlling the peak is what actually moves the bill. We typically run all four in combination.
Staggered startups
Large motors, compressors, and HVAC banks pulling in-rush current at the same moment create a spike that sets your demand charge for the month — even if it lasts seconds. We sequence startup timing across equipment so the same load comes online without ever stacking into one interval.
Load management
We map which loads actually need to run simultaneously versus which are running together by accident — shift schedules, batch timing, control logic that never got updated as the plant grew. Automated load shedding and scheduling keeps concurrent draw below your target threshold.
Peak shaving
Battery storage, on-site generation, or curtailment absorbs the top of a demand spike before it hits the meter. This is the direct lever on that single worst interval — it doesn't reduce usage, it flattens the peak that's setting your rate.
Turnkey system upgrades
Motors, drives, lighting, and controls that are 15–20 years old draw more than modern equivalents at every hour of the day. We scope, spec, and install the replacement — designed, procured, and commissioned as one project, not a parts list you have to assemble yourself.
The numbers behind the claim
This isn't a rounding error on your bill
The U.S. Department of Energy and the National Renewable Energy Laboratory have documented demand charges as a large, often-overlooked share of industrial electricity costs — and the reduction potential once they're actually engineered against.
Demand charges commonly make up 30–70% of the total electric bill for commercial and industrial facilities on demand-based rate schedules.
Facilities that implement peak shaving and load management have achieved demand charge reductions in the range of 15–40%, depending on load profile and equipment age.
A single 15-minute interval, once a month, sets the demand rate for every day that follows — which is exactly why it's the highest-leverage number on the bill.
Mission before money
If it won't pay for itself, we'll tell you
Every energy reduction proposal we write includes the payback math — not a rosy vendor estimate, but our own modeled interval data against your actual rate schedule. When the numbers don't clear a reasonable payback window, we say so, even when that means recommending a smaller project or no project at all.

How we get there
The process, start to finish
Four steps, one engineering team, no handoffs to a call center.
1
Interval data audit
We pull 12 months of interval-level utility data and rebuild your load profile hour by hour, isolating exactly which equipment and which minutes are setting your demand charge.
2
Payback-tested proposal
Every lever — staggering, load management, peak shaving, upgrades — gets modeled against your actual rate schedule. We only propose what clears payback; we tell you plainly when something doesn't.
3
Turnkey execution
Our team designs, procures, and installs — controls, sequencing logic, storage, or equipment — as one coordinated project on your production schedule, not a string of subcontractors.
4
Verified results
We measure the same interval data post-installation and show you the before-and-after on your own bill — not a modeled estimate, the actual number.
