Under TNB’s RP4 tariff, one 30-minute spike can set your demand charge for the entire month — at RM89.27 to RM97.06 per kW. Cobler’s CobiNeural platform watches those loads in real time and automatically shaves the peaks before they hit, so your monthly maximum demand stays low. No battery. No rip-and-replace. It runs standalone or over your existing BMS.
How do you reduce maximum demand charges in Malaysia?
You shave the peak. Maximum demand is billed on your highest 30-minute average kW in the month, so trimming short demand spikes — by automatically staging or curtailing large loads like chillers, AHUs and compressors — lowers the charge. Cobler does this with automated threshold-based control across your monitored equipment, no battery storage required.

Real deployments across hotels, hospitals, malls and commercial towers — not a pilot.
Maximum demand (MD) is the highest average power your site draws in any single 30-minute interval during the billing month, measured in kilowatts (kW). TNB doesn’t average your demand across the month — it charges you on that one peak half-hour. So if every chiller, pump and compressor happens to run together for 30 minutes on one hot afternoon, that spike sets your demand charge for all 30 days.
Under the RP4 tariff (effective 1 July 2025), the old MD charge was replaced by a combined Capacity + Network Charge, billed at RM89.27/kW per month for Medium Voltage General and RM97.06/kW per month for Medium Voltage Time-of-Use customers. On a 1,000 kW site, that’s roughly RM89,000–97,000 every month — before you’ve paid for a single kWh of actual energy.
The RP4 detail most people miss:
for Non-Domestic MV and HV customers, demand peaks that occur during the off-peak period are not charged. Shift or curtail your big loads so the monthly peak lands off-peak — or never happens — and the charge drops. That’s exactly what automated peak shaving does.
Peak shaving means keeping your demand under a target threshold so no single 30-minute interval spikes your bill. Cobler does it with automated, threshold-based control — a real, shipping capability, not a battery you have to buy.
CobiNeural sub-meters your major loads — chillers, air-handling units, compressors, pumps — and logs demand in real time, at the same 30-minute resolution TNB bills on.
We establish the kW ceiling that protects your bill, based on your tariff and load profile.
The platform tracks the rising half-hour average and sees a threshold breach before it registers on the meter.
CobiNeural stages, sequences or briefly curtails non-critical loads — trimming setpoints, delaying equipment starts, rotating compressors — to hold demand under the ceiling without disrupting operations.
Every intervention is logged, so you can see the peak that didn’t happen and the ringgit it saved.
Do you need batteries? No.
Cobler’s peak shaving works entirely through automated control of the equipment you already run — no capital outlay for energy storage. Battery energy storage (BESS) integration is on our roadmap for sites that want to push savings further, but it is not required to start cutting your demand charge today. This runs standalone or over your existing BMS and building automation.
The math is simple: every kW you shave off your monthly peak saves the full demand rate, every month. At RM89–97/kW, the savings compound fast.
| Peak reduction (kW) | Monthly saving (RM) | Annual saving (RM) |
|---|---|---|
| 20 kW | ~RM1,785–1,941 | ~RM21,400–23,300 |
| 50 kW | ~RM4,464–4,853 | ~RM53,600–58,200 |
| 100 kW | ~RM8,927–9,706 | ~RM107,100–116,500 |
| 200 kW | ~RM17,854–19,412 | ~RM214,200–232,900 |

Because automated peak shaving produces a measurable kW reduction against a known tariff, we can structure the commercials around the result. Talk to us about a performance-based arrangement where the platform is paid from the demand savings it delivers — so the reduction funds the project, not your capex budget. We shave the peak; you pay from what you save.

Across Cobler’s deployments in hotels, hospitals, malls and commercial towers, CobiNeural’s automated peak shaving trims the monthly maximum demand by staging and curtailing large loads before they spike. The equipment keeps running normally; occupants notice nothing except a lower bill. See the verified before/after kW and ringgit figures on our case studies.
See more resultsReducing demand isn’t just cheaper — it aligns with the standards and incentives Malaysian buildings are now measured against.
Large buildings (≥8,000 m²) and heavy consumers (≥21,600 GJ/yr) must run a documented energy management system and report performance. CobiNeural’s continuous metering and audit-ready data give your Registered Energy Manager the evidence those obligations require.
CobiNeural supplies the baselines and energy performance indicators these standards are built on. We provide the data layer; certification is issued by accredited bodies.
Verified operational monitoring supports Energy Efficiency credits, especially for Existing Building (O&M) certification.

Maximum demand is the highest average power your site draws in any single 30-minute interval during the billing month, measured in kilowatts (kW). TNB charges on that one peak half-hour, not your average — so a brief spike sets the charge for the whole month.
Under the RP4 tariff effective 1 July 2025, the demand-based Capacity + Network Charge is RM89.27/kW per month for Medium Voltage General and RM97.06/kW per month for Medium Voltage Time-of-Use customers. It replaced the older standalone maximum demand charge.
Peak shaving keeps your demand under a set threshold so no 30-minute interval spikes. By automatically staging or curtailing large loads before they push demand up, you lower the monthly peak that sets your charge. Every kW shaved saves the full demand rate, every month.
No. Cobler shaves peaks through automated threshold-based control of equipment you already run — chillers, AHUs, compressors, pumps — with no energy-storage capex. Battery (BESS) integration is on our roadmap but is not required to start saving.
No. CobiNeural trims setpoints, sequences equipment and briefly curtails non-critical loads within limits you approve. Occupants typically notice nothing — comfort and critical systems are protected while the peak is held down.
No. CobiNeural deploys standalone or over your existing building management system, reading your equipment and adding automated demand control without a rip-and-replace.
Energy (kWh) is how much electricity you use over time; maximum demand (kW) is how hard you draw it at the single peak moment. You pay for both separately — peak shaving targets the demand charge, which many buildings overpay because of short, avoidable spikes.
It depends on your load profile, but because the saving applies every month against RM89–97/kW, most sites see the reduction cover the project within the first year. Use the free MD calculator to estimate your own payback.
