Utilities
Utility-grade Transmission, Distribution, and Grid-scale Energy Infrastructure
Hasilwan supports utility operators with ultra-highvoltage (UHV), high voltage (HV), and medium voltage (MV)transmission and distribution infrastructure, including 500kV, 275kV, 132kV, 33kV, and 11kV substations, grid automation, and utility-scale renewable energy integration.
Energy Priorities & Challenges
Utility operators manage large-scale power systems where reliability, safety, and compliance are critical.
01
Grid Reliability & Stability
Maintaining stable power delivery across UHV, HV and MV networks under growing demand.
02
Ageing Grid Infrastructure
Upgrading existing substations, overhead transmission lines (OHTL), and underground cables (UGC) while keeping systems operational.
03
Network Expansion & Load Growth
Supporting new industrial zones, urban growth, and regional development.
04
Renewable Energy Integration
Connecting utility-scale solar and grid-scale BESS without compromising system stability.
05
Protection & Safety Requirements
Meeting strict protection, earthing, and grid code standards.
06
System Visibility & Automation
Improving monitoring, control, and fault response through SCADA, grid automation and grid digitalization.
