Acrel has completed a large‑scale chain‑restaurant energy‑monitoring cooperation with Brio Energy, a professional French system integrator. The project targets hundreds of Burger King restaurants around Paris, implementing refined sub‑metering and predictive maintenance for kitchen & store‑front electrical loads, to improve energy efficiency and reduce operational costs for retail catering chains.

Project Background

Brio Energy won the project through international bidding, searching for reliable multi‑circuits energy meters with external current transformers. Before the renovation, each Burger King restaurant only had a main incoming power meter. Operators could not acquire power consumption data of individual equipment, such as lighting, ventilation, deep fryers, ovens and refrigeration cabinets. Without branch‑circuit energy data, it was difficult to carry out energy optimization and equipment predictive maintenance.

Planned coverage

~300 Burger King restaurants

Implementation Plan

Phase‑1 finished, Phase‑2 in 3 years

Cumulative order value

575,000 RMB

Measuring capability

Up to 35 loads, min 0.02A

Main Technical Challenges

Limited internal space inside original distribution cabinets, requiring compact DIN‑rail multi‑loop measuring devices
Measuring points are scattered, cable distance between different circuits can reach 6‑8 meters
Some kitchen loads run under very small operating current
Demands for basic harmonic measurement to support equipment predictive maintenance
Data needs to connect and upload to Brio Energy's self‑developed cloud platform

Acrel Solution

After technical communication and sample testing, the customer selected ADW210‑D10‑4S and ADW210‑D16‑4S multi‑circuit energy meters, cooperating with AWT100‑CEHW LoRaWAN gateway, together with Milesight LoRaWAN gateway for data uplink.

Field commissioning and sample validation were finished during Mar‑Jul 2025. Batch purchasing for 60 stores started in Oct‑Nov 2025. Another 30 restaurants were ordered in 2026, with further 30 sites to follow.

Project Benefits & Value

Refined energy data collection

Real‑time reading for lighting, ventilation, fryers, ovens and cold‑storage equipment, no manual meter‑reading.

Predictive maintenance

Harmonic & power data identify abnormal equipment, reduce kitchen device breakdown risk.

Cross‑store KPI benchmarking

Compare energy‑use indicators between sites, locate high‑consumption points, guide energy‑saving retrofit.

Third‑party system integration

Hardware seamlessly connects with Brio Energy cloud platform without heavy custom development.

Future Business Outlook

According to the cooperation plan, more than 50 new restaurant sites will be upgraded every year. Based on the successful Burger King implementation, Brio Energy intends to promote this Acrel multi‑circuit sub‑metering solution to other famous European catering retail brands, including McDonald's and KFC.

Drawing on mature experience from chain retail projects (such as Lawson convenience‑store energy‑monitoring cases in China), Acrel provides complete hardware selection, sample testing, remote online technical support and third‑party platform docking services for overseas integrator partners.
