Supporting lower temperatures

February 25, 2025
As part of its decarbonization strategy, our customer needs to lower the temperature of its thermal network to integrate more renewable heat sources (heat pumps, waste heat recovery, solar thermal). To achieve this, he needs a better understanding of substation dynamics to optimize energy efficiency while keeping investment costs under control.

Challenge

Our customer was facing several major constraints:
Lack of digitization: Its network was operating without a precise monitoring system, making any optimization complex.
Limited control of substations: Lack of visibility of heat exchanger performance hampered necessary adjustments.
Budget and time constraints: A fast, cost-effective solution was needed, without heavy intervention on the existing infrastructure.

Solution

We deployed a retrofit technology enabling immediate network modernization, without costly equipment replacement. Thanks to a progressive, optimized approach, we were able to ensure an effective digital transition in just a few weeks for several dozen substations.

Project milestones :

1️⃣ Network diagnostics: Identification of critical substations and optimization opportunities.
2️⃣ Deployment of IoT systems: Rapid installation of M2M gateways for continuous collection of accurate data without service interruption.
3️⃣ Implementation of a cloud platform: Centralization and real-time analysis of consumption, temperature and thermal efficiency data.
4️⃣ Reliable analyses: Implementation of a model to characterize heat exchange and assess the impact of temperature reduction.
5️⃣ Progressive optimization: Dynamic temperature adjustments to maximize energy efficiency and integrate new heat sources.

Results

Analysis of SSTs to be optimized in order to achieve lowering targets without exchanger replacement.
Improved energy efficiency thanks to continuous optimization of settings.
Reduced operating and maintenance costs by limiting equipment wear and tear and avoiding premature replacement.
Accelerated deployment: A digital transformation completed in 4 weeks, without any major work.

By adopting a turnkey digital retrofit strategy, our customer was able to improve the reliability and performance of its network while reducing its carbon footprint. A key solution for network operators wishing to accelerate their energy transition without heavy investment.
