Lyon, France – August 2031 – EDF, France’s leading energy provider, has achieved a 4% improvement in gas turbine efficiency and a 35% reduction in fuel consumption costs at its Lyon combined-cycle gas power plant after deploying the ABB VP01 valve positioner module. The upgrade, completed in Q1 2031, replaced the plant’s outdated valve positioners, which struggled with slow response times and imprecise fuel flow control—leading to inefficient turbine operation and high greenhouse gas emissions.
The Challenge: Outdated Valve Positioners Limit Turbine Performance
EDF’s Lyon power plant features 4 gas turbines with a total capacity of 800 MW, supplying electricity to 600,000 households in the Auvergne-Rhône-Alpes region. The plant’s legacy valve positioners control the flow of natural gas to the turbines, a critical process that directly impacts efficiency and emissions. The legacy systems presented critical operational challenges:
- Slow Response Time Reduces Efficiency: The legacy positioners had a response time of 600 ms, unable to adjust fuel flow quickly to match turbine load changes. This led to inefficient fuel combustion, reducing turbine efficiency by 4% and increasing fuel consumption by €3.2 million annually.
- Imprecise Fuel Flow Increases Emissions: Poor positioning accuracy (±2.5% of full scale) caused uneven fuel distribution to the turbine burners, leading to incomplete combustion. This resulted in higher NOx and CO emissions, exceeding EU Emissions Trading System (ETS) limits and incurring annual fines of €250,000.
- High Maintenance Costs: The mechanical components of the legacy positioners were prone to wear in the high-temperature turbine environment (up to 120°C), requiring monthly maintenance. Annual maintenance costs exceeded €850,000, with frequent unplanned downtime disrupting power supply.
- Inadequate Remote Monitoring: The old systems lacked remote monitoring capabilities, requiring technicians to perform on-site inspections of valve positions. This increased labor costs and delayed the detection of potential valve issues, leading to more severe failures.
“Gas turbine efficiency is critical for reducing fuel costs and meeting our carbon reduction goals,” said Pierre Lefèvre, EDF Lyon Power Plant Manager. “Our legacy valve positioners were too slow and imprecise to optimize turbine performance, leading to unnecessary fuel waste and emissions. We needed a high-performance valve positioner solution that could deliver fast, precise fuel flow control, reduce maintenance costs, and support remote monitoring.”
ABB VP01 Valve Positioner Module: High-Speed Precision for Gas Turbines
After evaluating solutions from Siemens and GE, EDF selected the ABB VP01 valve positioner module for its ultra-fast response time, precise fuel flow control, high-temperature tolerance, and remote monitoring capabilities. Key features addressing EDF’s pain points include:
- Ultra-Fast Response Time: The ABB VP01 valve positioner module has a response time of 40 ms—15x faster than legacy systems. This enables real-time adjustment of fuel flow to match turbine load changes, optimizing combustion efficiency and increasing turbine efficiency by 4%.
- Precise Fuel Flow Control: With positioning accuracy of ±0.1% of full scale, the VP01 module ensures uniform fuel distribution to the turbine burners, enabling complete combustion. This reduces NOx and CO emissions by 30%, ensuring compliance with EU ETS limits.
- High-Temperature Tolerance: The module features a robust design with an operating temperature range of -40°C to 150°C, withstanding the harsh conditions near the gas turbines. Its non-contact sensor technology eliminates mechanical wear, increasing MTBF to 8 years—4x longer than legacy positioners.
- Remote Monitoring & Diagnostics: Supporting 4G/LTE and PROFINET protocols, the VP01 module enables remote monitoring of valve position, temperature, and performance via EDF’s SCADA system. Predictive diagnostic algorithms identify potential issues (e.g., sensor degradation, valve sticking) 3-5 weeks in advance, reducing unplanned downtime by 75%.
- Energy-Efficient Operation: The VP01 module uses low-power electronics, reducing energy consumption by 50% compared to legacy systems. Its compact design fits easily in the limited space around the turbines, simplifying installation.

“The ABB VP01 valve positioner module has been a game-changer for our power plant,” Lefèvre said. “The 4% improvement in turbine efficiency has translated to significant fuel cost savings, and we’re now fully compliant with EU emissions regulations. The remote monitoring capabilities have also reduced our maintenance workload, allowing our technicians to focus on proactive maintenance rather than reactive repairs.”
Thomas Berger, ABB’s Global Power Generation Automation Manager, commented: “Gas power plants require valve positioners that can deliver fast, precise control in harsh environments. The ABB VP01 valve positioner module meets these demanding requirements, helping power providers improve efficiency, reduce costs, and lower emissions.”
EDF plans to deploy the ABB VP01 valve positioner module across 28 additional gas power plants in France and other European countries by 2037, targeting a 3.5% group-wide improvement in gas turbine efficiency and a 30% reduction in fuel consumption costs.
Lausanne, Switzerland – July 2031 – Nestlé, the world’s leading food and beverage company, has achieved a 55% reduction in material waste and a 38% increase in production line efficiency at its Lausanne production plant after deploying the ABB VP01 valve positioner module. The upgrade, completed in Q2 2031, replaced the plant’s outdated valve positioners, which struggled with imprecise flow control and poor hygiene compliance—leading to product contamination risks and high material waste in the production of dairy products and bottled water.
