Get connected. Without the guesswork.
We manage the technical and administrative path between your renewable energy project and the Distribution Network Operator, from early feasibility through to the connection offer.
BUILT AROUND YOUR PROJECT
Generation, storage and constrained export.
From a commercial rooftop solar array to a multi-technology site, we shape the application around how the electrical system will actually operate.
COMMERCIAL SOLAR PV
New generation systems and extensions to existing installations.
BATTERY ENERGY STORAGE
Standalone battery systems and solar-plus-storage projects.
EXPORT-LIMITED SYSTEMS
G100 export-limitation strategies and associated technical information.
LV AND HV CONNECTIONS
Project-specific coordination for low-voltage and high-voltage connections.

From residential installations to large utility scale, we can help.
We review the site, proposed capacity, point of connection and operating intent. We then establish the correct application route before detailed work begins.
• G98 or G99 route review
• Proposed export capacity
• Generation and storage review
• Key risk identification
• Initial information-gap assessment
We prepare a coherent DNO application pack containing the project information and engineering documents required for technical assessment.
• DNO application schedules
• Single-line diagrams
• Equipment specifications
• Inverter and battery information
• Protection details
• Export-limitation information
We act as the technical point of contact during the assessment process, responding to engineering queries and requests for further information.
• DNO query management
• Design clarifications
• Additional information requests
• Application progress tracking
• Coordination with the wider project tea
When the connection offer arrives, we translate its technical conditions, constraints and dependencies into a practical next-step plan.
• Connection conditions
• Permitted import and export capacities
• Network reinforcement requirements
• Protection and metering obligations
• Export limitations
• Design implications and next actions
As early as practical. Connection constraints can materially affect system capacity, export strategy, equipment selection and the project programme.
Early assessment reduces the risk of developing a design around capacity the network cannot provide.
No. The Distribution Network Operator controls its network and determines the connection capacity it can offer.
Our role is to submit a technically coherent application, respond efficiently to engineering queries and help you understand the available options if the requested capacity is constrained.
• Site address
• MPAN, where available
• Proposed solar PV capacity
• Proposed battery capacity
• Inverter and battery selections
• Existing electrical information
• Proposed point of connection
• Single-line diagram, where available
• Intended import and export capacities
