Commercial Battery Storage

Commercial battery storage systems enable UK businesses to store surplus solar energy and utilise it during periods of peak demand or high electricity tariffs. For companies delivering commercial solar installations, integrating battery storage adds significant value to the overall energy solution—enhancing system efficiency, reducing grid reliance, and supporting a more comprehensive approach to energy management.

Main features:

• Increased Solar Self-Consumption - Help customers maximise the use of their on-site solar energy, reducing reliance on the grid and minimising export losses.

• Additional Revenue Streams - When a business installs a commercial battery storage system, it can do more than just store excess solar energy — it can also participate in national energy markets to generate income. This is typically achieved through two main routes in the UK:

  1. Grid Balancing Services - The National Grid occasionally requires support to maintain real-time balance between electricity supply and demand. Businesses with battery storage can contribute by either discharging stored energy to the grid or temporarily reducing consumption. In return, they receive financial incentives or capacity payments.
  2. Demand-Side Response (DSR) - DSR schemes involve adjusting on-site energy usage in response to grid signals during periods of peak demand or system stress. With battery storage, businesses can participate by discharging energy or shifting loads, earning compensation in return.
• Reduced Electricity Costs - Rely on battery storage to offset energy use during peak pricing, cutting costs and improving efficiency.
• Energy Security - Maintain critical operations by providing reliable backup power in the event of grid instability or power loss.
• Enhanced Sustainability - Improve business's green credentials by maximising the use of renewable energy.

Here are some practical applications:

Peak Shaving

Reduce demand charges by discharging stored energy during periods of peak consumption.

Load Management

Align energy consumption with on-site generation to create a more stable and efficient energy profile.

Backup Power Supply

Enhance energy resilience by providing reliable backup power during grid interruptions or outages.

EV Charging Integration

Support low-carbon transport strategies by combining solar and storage to enable efficient electric vehicle (EV) fleet charging.

Integrating battery storage into a solar PV system is central to delivering efficient, scalable, and long-term energy solutions for UK businesses. Choosing the right energy storage system ensures maximum return on investment, enhanced energy resilience, and long-term sustainability.

When designing and installing C&I battery energy storage systems, it’s important to assess several technical and site-specific factors to ensure reliable performance and long-term value for the end user:

• Energy Usage Profile: Understanding the customer’s typical energy consumption and peak demand periods helps determine the appropriate battery size and discharge strategy.
• Installation Space : Evaluate the available space for installation, whether indoors or outdoors. It is important to consider factors such as ventilation, safety clearances, and compliance with UK electrical and fire safety regulations.
• Scalability and Flexibility: Choose modular battery solutions that can grow with the customer’s energy demands. This ensures the system remains adaptable as businesses expand.
• Grid Connection and Compliance: The systems should meet UK requirements for grid connection, including those set by the Distribution Network Operator (DNO) and G99 standards. Proper compliance is essential for system approval and participation in grid-related services.
