Connection Capacity
Available capacity at the point of connection can constrain how much power a battery may charge or discharge.
Grid Connection
Grid Connection Analysis
Grid connection can be one of the most important constraints in a BESS project. Understanding the electrical interaction between the battery, site and grid at an early stage can prevent costly design changes later.
Scope
Topics We Assess
Import / Export Limits
Existing import and export limits may restrict the operating range of a combined PV and battery installation.
Power Flow
Power flows between the battery, the site loads and the grid can be examined to identify possible constraints.
Voltage Considerations
Battery operation can affect local voltage levels, depending on network strength and impedance.
Transformer Considerations
Transformer rating, loading and losses may influence how a battery can be connected and operated.
Loading
Simultaneous operation of the battery with existing loads or generation can change loading patterns on the connection.
BESS Operating Limits
The intended charge and discharge profile can be compared against the technical limits of the connection.
PV + BESS Interaction
Where solar is present, the combined behaviour of PV and battery can affect flows at the metering point.
Grid-Support Considerations
Depending on the grid code, a battery may be able to contribute services such as frequency support.
Preliminary Technical Assessment
An early indicative view of grid-related risks can help flag issues before formal studies are commissioned.
Important Note
Preliminary analysis does not replace formal grid-connection studies, utility requirements or approvals by the relevant grid operator.
Battery, Site and Grid as One System
A battery never operates in isolation. Its behaviour at the point of connection depends on the site loads, any on-site generation, the transformer and the strength of the surrounding network. Looking at these elements together, early in the project, makes it easier to spot where the design and the grid may pull in different directions.
