Measure the real constraint
Establish whether the limiting factor is contracted demand, transformer capacity, generator capacity, tariff exposure or inadequate operating visibility.

Peak Shaving & Industrial Demand Management in Pakistan
JME Energy & Automation engineers control strategies that coordinate grid import, BESS, solar PV, gensets and manageable loads to reduce demand peaks without compromising critical plant operations.
Grid DemandMonitor point-of-coupling import
BESS DispatchDischarge within safe limits
Load PriorityPreserve critical operations
Generator SupportRespect loading constraints
The engineering objective
Control the peak, not the plant
Demand management is not simply switching loads off. The control system must understand available capacity, tariff periods, battery state of charge, generator limits, process priorities and the duration of the expected peak.
02
Define the response
Choose the correct mix of BESS discharge, solar utilization, staged load control, generator support or operator notification.
03
Prove recovery behaviour
Define how loads return, how battery reserve is restored and how the system behaves after utility, meter or communication failure.
Closed-loop demand control
From measurement to controlled response
JME connects meters, controllers and controllable assets through an EMS or PLC layer with transparent limits and operator visibility.

Peak-shaving strategies
BESS peak shaving
Discharge when measured import exceeds the agreed target, subject to PCS power, battery SOC, temperature and reserve requirements.

Time-based dispatch
Coordinate charging and discharging around tariff windows where the commercial and technical operating strategy supports it.
Dynamic load shedding
Remove lower-priority loads in stages when available capacity is insufficient, then restore them using stable thresholds and delays.
Solar utilization
Use available PV production while respecting zero-export, generator-loading and equipment limitations.
Generator assistance
Start or load generators when the agreed operating philosophy requires additional capacity or resilience.
Operator-guided control
Provide alarms, recommended actions and demand forecasts where automatic control is unnecessary or operational approval is required.
Inputs required for a dependable design
| Input | Why it matters |
|---|---|
| Load profile | Shows the magnitude, frequency and duration of demand peaks. |
| Tariff and demand limits | Defines the commercial target and operating windows. |
| BESS capability | Confirms usable power, energy, SOC limits and supported PCS modes. |
| Generator limits | Protects minimum loading, reverse power, ramping and available capacity. |
| Load priorities | Separates critical, essential, deferrable and shed-capable loads. |
| Metering and communications | Determines response speed, accuracy and failure handling. |
Engineering note: Peak shaving must be based on verified measurements and an agreed control philosophy. Battery capacity alone does not guarantee successful demand reduction; discharge duration, site variability and reserve requirements must also be considered.
Peak shaving and demand management FAQs
What is industrial peak shaving?
It is the controlled reduction of a facility’s maximum electrical demand using battery discharge, generation, renewable energy or manageable loads.
Can BESS peak shaving work during load shedding?
It can support both demand reduction and backup objectives, but the control philosophy must preserve sufficient state of charge and respect PCS operating modes.
Is peak shaving the same as load shedding?
No. Peak shaving may use BESS or generation without interrupting loads. Load shedding intentionally disconnects selected loads when capacity is insufficient.
Can JME integrate an existing BESS or meter?
Yes, when the installed devices expose suitable measurements and commands through supported interfaces such as Modbus RTU, Modbus TCP, RS485 or Ethernet.
How is performance verified?
Performance should be checked using time-synchronized demand, source-power, battery, alarm and operating-mode trends against agreed acceptance criteria.
Do demand peaks exceed your available capacity?
Share 12 months of utility bills, available 15- or 30-minute demand data, tariff information, SLD, BESS details, generator capacities and critical-load priorities for an initial engineering review.
