Challenge

The best time to establish protocols with your clients is when you onboard them.

As the UK moves toward net-zero 2050, balancing supply and demand from renewable sources has become critical. The challenge was to store and utilise excess renewable energy efficiently, preventing waste and stabilising market prices.

Solution

The best time to establish protocols with your clients is when you onboard them.

Battery Performance Monitoring: Real-time, sub-second monitoring of battery cells, capturing up to 18,000 data points every 10 seconds.

Predictive Analytics: AI-based anomaly detection to improve efficiency and maximise financial performance.

Dashboard Visualisation: Converting complex data into actionable insights for quick decision-making and issue resolution.

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.
