Solutions · NMD reduction
Notified maximum demand reduction.
On large-power-user tariffs a single half-hour can set the demand charge for the month, and repeated breaches push the notified maximum demand up for good. A battery shaves those half-hours off.
01 · How it works
Four steps,
every day.
- 01Watch the rolling half-hourSolaris tracks demand in each half-hour integration period at the point of connection.
- 02Discharge before the limitAs demand approaches the ceiling, the battery supplies the difference, so the half-hour never records the spike.
- 03Hold a reserve for itEnergy for demand control is held back from arbitrage on days with high-load risk.
- 04Lower the NMD at renewalMonths of capped demand are the evidence for applying to reduce the notified maximum demand.
02 · The numbers
What decides
the value.
| Charged on | Demand in the chargeable periods (kVA) and the capacity you hold with the utility |
| Battery role | Pre-emptive discharge against a rolling demand integral |
| Response | Sub-second, four-quadrant |
| Pairs with | Peak shifting on the same battery |
03 · Questions
Asked before
the first meeting.
What is notified maximum demand?
The capacity a large-power user has agreed with the utility, in kVA. Network charges are levied on that capacity and on the demand recorded in the chargeable periods, and exceeding it attracts excess charges.
Can one battery do demand control and peak shifting?
Yes. Solaris runs both against the same state of charge and holds back a reserve on days when a demand spike is likely.
How quickly can we lower our NMD?
That is set by the utility's rules for changing the notified demand. The battery provides the operating evidence; the application is yours, and we help prepare it.
Next step
Start with your meter data.
Twelve months of interval data, your tariff schedule and your notified maximum demand are enough for a first sizing, an indicative capex and a PPA rate, within five working days, at no cost.
