Case Study: Monitoring 150MWh Battery Farm

Q Energy provided predictive maintenance and performance monitoring for Europe’s largest battery storage facility in Minety, UK—turning high-frequency BESS telemetry into actionable insights that improve reliability, stability and financial performance.

Challenge

As the UK moves toward net-zero 2050, managing the balance between intermittent renewable output and demand is critical. Minety required a way to store surplus energy, reduce curtailment and stabilise market prices without sacrificing reliability.

Solution

• Battery Performance Monitoring System: Sub-second, real-time data capture from cells—up to 18,000 data points every 10 seconds.
• Predictive Analytics: AI models detect anomalies early to improve efficiency and financial performance.
• Dashboard Visualisation: Clear, decision-ready dashboards to accelerate issue resolution.

Results

• Enhanced Energy Management: Tighter control of stored energy improves grid stability and dispatchability.
• Preventive Maintenance: Early detection reduces downtime and preserves asset performance.

Impact

• Capacity & Coverage: 150 MW supports ~15,000 homes for 24 hours, accelerating the transition to net-zero.
• Innovative Technology: A benchmark for data-driven BESS operations and maintenance.
• Collaboration & Investment: Partnerships with Shell, Sungrow and The Huaneng Group showcase scalable deployment.

Following Minety, Q Energy is deploying the same model across new regions—expanding predictive maintenance capabilities and improving reliability of renewable energy storage systems at scale.
