Generating power is only half the project; connecting it to the grid compliantly is the other half, and it is where many solar and storage projects stall. PrismFlow manages the entire interconnection process end to end, from the first feasibility study to the final permission-to-operate, so your system energises on schedule instead of waiting in a queue.
Interconnection studies
Before a utility approves a connection, it needs to know your system will not destabilise the local network. We perform the engineering studies that prove it: load flow, short-circuit, protection coordination, and where required, detailed impact studies that model how your generation behaves on the feeder. We deliver utility-ready documentation that answers the operator's questions before they are asked.
Our designs align with IEEE 1547 and local interconnection standards from the outset, configuring smart inverters for the voltage and frequency ride-through, anti-islanding, and grid-support functions modern utilities expect. Getting the engineering right up front is what keeps an application moving rather than bouncing back for revisions.
Permitting and approvals
Permitting is a maze of jurisdictions, forms, and deadlines. We assemble the complete application package, submit it, and act as the single point of contact between you, the authority having jurisdiction, and the utility. When questions or revision requests come back, we handle them directly, keeping the project advancing without consuming your team's time.
- Feasibility and system-impact studies prepared to utility standards
- Protection and relay coordination for safe, compliant operation
- Smart-inverter configuration aligned to IEEE 1547 grid-support modes
- Full permit assembly, submission, and authority correspondence
- Witness testing, commissioning, and permission-to-operate sign-off
One team, start to finish
Because PrismFlow designs your generation and storage in the first place, interconnection is not a hand-off to a separate vendor. The same team that sized your array configures the inverters, prepares the studies, and shepherds the paperwork, which means fewer gaps, faster approvals, and a system engineered from day one to integrate cleanly with the grid.
That integration-first approach pays dividends later, too. A correctly interconnected system is ready to participate in advanced grid services and virtual power plants down the line, with the compliance groundwork already in place.
Facing an interconnection queue or a stack of utility paperwork? Hand it to our team and we will carry your project all the way to permission-to-operate.
Frequently asked questions
How long does interconnection take?
Timelines vary by utility and system size, but most delays come from incomplete or non-compliant applications. By preparing utility-ready studies and documentation up front, we keep projects moving and avoid costly resubmission cycles.
Do I need an interconnection study?
Smaller systems may qualify for streamlined review, while larger or higher-impact projects require formal studies. We assess your case early and prepare exactly the level of analysis your utility requires.
What is IEEE 1547 and why does it matter?
IEEE 1547 is the standard governing how distributed generation interconnects with the grid. We configure smart inverters to meet its ride-through, anti-islanding, and grid-support requirements so your system is compliant from the start.
Do you handle the paperwork with the utility?
Yes. We assemble and submit the full application, act as your single point of contact with the utility and permitting authority, and manage all correspondence through to permission-to-operate.
