Large Residential Customer – Large PV and Residential Battery Installation

Challenge
A resident of Milton Keynes faced extraordinarily high energy bills, with the latest monthly bill before our intervention at £1,845.32. This extensive energy demand arose from his large estate, featuring multiple amenities such as pools and a heat pump. The client sought to significantly reduce his energy costs and achieve greater energy self-sufficiency.

Solution
Q Energy tailored a sophisticated energy management system centred around its SmartQube hub to transform the estate into an almost entirely self-sufficient unit:

• 70 kW Ground-Mounted PV System: Maximises solar energy capture.
• 215 kWh Commercial-Grade Battery Storage: Stores excess solar energy for use during peak demand periods, reducing grid dependence.
• EV Charger Installation: Seamlessly integrates with the energy management system to optimise charging based on available energy and lowest cost.
• Export Tariff Participation:  Leveraging favourable rates to sell excess solar PV energy, using our AI technology – SmartQube optimises to maximise financial returns.
• Optimisation Based on Time of Use Tariff: Using the client’s selected tariff we exploit lower rates during off-peak hours for further savings.
• SmartQube Hub Integration: The core of the system, SmartQube, uses advanced AI algorithms to monitor and optimise battery charge and discharge cycles precisely aligned with the client’s energy consumption patterns. It intelligently manages the timing and amount of energy exported, ensuring optimal financial return from surplus energy while maintaining household energy needs.

Results
The integrated solution yielded impressive results from the outset:

• Immediate Cost Savings: The client saved £1,546.56.
• Increased Energy Independence: Dramatically reduced reliance on external power sources.
• Revenue from Energy Export: Enhanced financial benefits from the strategic sale of excess energy, automated by SmartQube’s intelligent energy management capabilities.

Impact
This project exemplifies how residential properties can approach full energy self-sufficiency by integrating solar power, battery storage, and intelligent energy management. The Q Energy SmartQube hub plays a pivotal role in this transformation, employing sophisticated AI to not only optimise energy usage and storage but also to maximise the economic benefits of energy production and consumption. This case highlights the transformative impact of technology on managing and reducing household energy costs and contributing to environmental sustainability.
