Delivering Reliable, Efficient Energy Solution for Telecom Sites

Client: China Mobile Guangdong XXX Base Station

Challenges & Requirements

With the rollout of 5G technology, the power consumption of base stations has increased significantly, consuming 3-4 times more energy than 4G stations. The existing power distribution system cannot meet these demands. Key requirements include:

• Extended Backup Power: Ensure stable operation with 1 hour backup for wireless equipment, 3 hours for auxiliary equipment, and 10 hours for transmission equipment.
• Reduced Energy Loss: Lower electricity costs and improve energy efficiency.
• Lower Maintenance Costs: Optimize energy management to reduce daily maintenance and operational costs.

Our Solution

To address these needs, Juding designed a comprehensive grid-connected photovoltaic energy storage system.

Power and Backup Analysis:

• Designed for an average power consumption of 5KW, meeting daily operational needs.

System Design:

• Energy Storage: 50kWh capacity.
• Power Configuration: -48V100A for communication equipment and 3KW/220V for auxiliary equipment.
• Generation Method: High-efficiency polycrystalline silicon photovoltaic system, supplemented by off-peak grid power for continuous supply.

Complementary Power Supply:

• Uninterrupted supply via photovoltaic generation, energy storage batteries, and off-peak grid power.
• Maximizes cost reduction and uses clean energy to support carbon peak goals.

Solution value

The 50kWh energy storage cabinet and solar + grid + storage solution offers:

• Annual Savings: Approximately 23,945 RMB in electricity costs.
• Payback Period: Around 6 years.

This solution meets the energy needs of the telecom site, reducing operational and maintenance costs, enhancing efficiency, and supporting sustainable development.
