THE PROJECT SITUATION
Replacing Diesel Generators On Highway Tunneling Project
China Communications Construction Company was contracted to perform the Zentian highway tunneling works as part of the Guangzhou suburban ring road expansion project. The project required a solution that could reduce diesel generator capacity and fuel costs while handling varying power loads.

The conventional setup used 2,500kVA diesel generators to power 6 air compressors (total 792kW). This resulted in:

• Excessive noise pollution

• High diesel fuel consumption

SENMARCK HYBRID POWER SOLUTION
The Senmarck PowerMore BESS & Generator Parallel Power Output Technology
Senmarck supplied:

• Two synchronized PowerMore250A BESS units (300kWh Battery Energy Storage System)

• Two 365kW diesel generators
       This hybrid system replaced the 2,500kVA diesel generators.

Key Features:

• Charges from either grid or generators (no need for 100% charge)

• Uses parallel power output technology to discharge batteries and generators simultaneously

• Handles short-period peak loads effortlessly

• Delivers stable, energy-efficient, low-emission power

THE BENEFITS
Reduction In Generator Capacity – Fuel Costs, Maintenance, Emissions & Noise
The transition from 100% diesel to hybrid power delivered remarkable results:

• 60% reduction in generator runtime

• 45% lower energy costs compared to diesel-only solutions

• Significant reductions in:

• Fuel consumption

• Maintenance requirements

• Onsite noise pollution

• CO₂ emissions
