Against the backdrop of global energy conservation and carbon reduction, a high-energy-consuming industrial park in the Pearl River Delta faced high electricity costs and unstable power supply. Shenzhen Borui Smart Control Co., Ltd. provided a customized solution based on 522kWh liquid-cooled energy storage cabinets, achieving significant energy-saving results.

Project Background & Customer Needs

The electronic component manufacturing park operates 24/7, with core pain points: high peak electricity costs (28% of total operating costs), unstable grid power supply, and wasted excess photovoltaic power. Its needs are to cut electricity costs, ensure stable power, and improve photovoltaic utilization.

Borui’s Customized Solution

Borui provided an integrated energy storage solution centered on 522kWh liquid-cooled energy storage cabinets, including:

1. Core Configuration: 4 sets of 522kWh liquid-cooled cabinets (total 2088kWh), adopting safe, long-life lithium iron phosphate batteries and liquid-cooled heat dissipation for stable high-temperature operation.

2. Intelligent Control: Borui’s self-developed energy management system realizes automatic peak-valley charge-discharge (valley: 00:00-08:00; peak: 09:00-23:00) to reduce grid peak power usage.

3. PV-Storage Integration: Connects to the park’s existing PV system, storing excess daytime power for peak/night use to maximize renewable energy utilization.

Project Effects & Customer Benefits

Since its March 2024 launch, the project has delivered remarkable results:

1. Cost Reduction: 33% lower monthly electricity costs, saving over 2 million yuan annually.

2. Stable Power: 99.8% system stability rate, acting as backup power to avoid outage losses.

3. Carbon Reduction: 45% higher PV utilization, cutting annual carbon emissions by ~1200 tons.
