Key Highlights

Project Scale

Residential property with swimming pool

Assets

Two 18kW heat pumps, 180kWh battery, SmartQube

Outcomes

£10,465 savings (53.8% of the bill) for first year

Challenge

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

The homeowner was committed to decarbonising his property, which included a main house and a swimming pool complex, both served by three gas boilers. The objective was to replace these carbon-intensive systems with more sustainable technology without compromising on efficiency and while ensuring financial viability.

Solution

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

To address these needs, we implemented a dual heat pump system using two Heliotherms 18kW heat pumps—one for the house and one for the pool. Additionally, we installed a 180 kWh battery system with a 30 kW inverter, optimised for energy cost savings through the Octopus Go tariff, enabling 6-hour nightly charging at a low rate of 7.5p. The installation was managed in collaboration with our installation partner, MJS Energy, with the client deciding not to incorporate solar panels.

Results

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

  • Energy Cost Reduction: The Q Energy SmartQube system facilitated a significant reduction in energy costs, saving the homeowner £10,465 in the first 12 months.
  • Energy Bill Reduction: Achieved a 53.8% reduction in the energy bill during the first year.

Impacts

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

The project not only met the client’s financial and environmental goals but also showcased the potential of integrating advanced heat pump technology and smart energy management systems in residential settings:

  • Decarbonisation: By replacing gas boilers with heat pumps, the client significantly reduced their carbon footprint.
  • Financial Efficiency: The strategic use of tariff and energy storage allowed the homeowner to maximise financial savings and enhance the property’s energy efficiency.
  • Sustainable Living: This initiative reflects a shift towards sustainable living practices, setting a precedent for similar residential projects.

150 MW → ~15,000 homes / 24h
Data Ingestion
18,000 pts / 10s
Outcome
Higher uptime & stability

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.
