Battery Energy Storage Systems: The Solution to Malaysia's Industrial Demand Charges

BESS (Battery Energy Storage System) is an industrial-grade solution that stores electrical energy during low-cost periods and intelligently discharges during peak demand periods, eliminating TNB's maximum demand penalties while optimizing energy costs.

How BESS Works: 24-Hour Operation Cycle

Off-Peak (10pm-2pm + Weekends)

Charge at Low Cost

Battery charges at ~27 sen/kWh. MD during off-peak is NOT charged.

Peak Hours (2pm-10pm Weekdays)

Discharge & Cap Peak Demand

Battery supplies power at ~31 sen/kWh and caps MD - avoiding RM 89-97/kW/month charges.

Demand Spikes (Anytime)

Eliminate MD Penalties

Automatically supplies power during spikes - saves RM 89-97/kW/month per kW reduced.

Key Insight: BESS charges when electricity is cheap (off-peak) and discharges during peak hours to keep your demand below the MD threshold — saving RM 89-97/kW/month.

Key Advantages of Industrial BESS

Demand Charge Reduction

Reduce TNB Capacity + Network charges up to 100% by capping peak power draw. Typical savings: RM 89-97/kW/month for every kW reduced (Medium Voltage). Higher impact with new July 2025 tariff.

Time-of-Use Arbitrage

Charge during off-peak (27 sen/kWh) and discharge during peak hours (31 sen/kWh). Main savings come from eliminating Maximum Demand charges of RM 89-97/kW/month.

Backup Power & Grid Independence

Seamless switchover (<10ms) during outages. Protects critical operations, prevents production losses, ensures business continuity.

Solar-Ready Integration

Works standalone or with solar PV. Start with BESS now, add solar later for maximum savings. Flexible, future-proof investment.

BESS Solutions Across Industries

Proven applications for diverse industrial and commercial facilities

Manufacturing & Industrial

High peak demand from heavy machinery, CNC equipment, compressors, and production lines.

Key Pain Point:
Demand charges from equipment startup spikes and simultaneous operation
BESS Benefit:
Up to 100% demand charge reduction, TOU savings, production continuity

Commercial Buildings & Offices

High-rise buildings, shopping centers, office towers with limited roof space.

Key Pain Point:
HVAC peak demand, no roof space for solar, urban location constraints
BESS Benefit:
Works without solar, demand shaving, tenant billing optimization

Data Centers & IT Facilities

Mission-critical facilities requiring uninterruptible power and consistent loads.

Key Pain Point:
24/7 operations, zero downtime tolerance, high baseload costs
BESS Benefit:
<10ms backup switchover, TOU arbitrage, demand management

Healthcare Facilities

Hospitals, clinics, medical centers with critical power requirements.

Key Pain Point:
Life-support systems, surgical equipment, refrigeration for medications
BESS Benefit:
Seamless backup power, cost reduction, regulatory compliance

Cold Storage & Food Processing

Refrigeration facilities with high compressor loads and temperature-critical operations.

Key Pain Point:
Compressor startup spikes, continuous cooling loads, product loss risk
BESS Benefit:
Peak shaving during defrost cycles, backup for critical cooling

Hospitality & Hotels

Hotels, resorts, restaurants with variable demand patterns and guest comfort priorities.

Key Pain Point:
Variable occupancy, kitchen equipment peaks, HVAC demand
BESS Benefit:
Demand optimization, uninterrupted guest experience, cost control

Want Maximum Savings? Add Solar to BESS

For facilities with available roof space, combining BESS with solar PV delivers the highest ROI. Generate free energy during the day, store it in batteries, eliminate both energy costs AND demand charges. 3-5 year payback. GITA incentives may apply*.
