Interconnection software: queue workflow and study tools
Two kinds of software work a queue. Workflow platforms run the application, deposits and milestones: GridUnity GridInterConnect covers study deposits and network upgrade costs under FERC Order 2023 cluster management, and Clean Power Research PowerClerk is a no-code SaaS for large generators and large loads. Study tools run the power flows: Siemens PSS E models up to 200,000 buses, and PowerWorld ships a free 13-bus evaluation version.

Workflow tools or study tools
How rows are readWorkflow platforms
These are for the party that receives applications. GridUnity is cloud SaaS from application to commissioning. PowerClerk tracks project status, milestones, deadlines and tasks and connects by API, no-code connector or file exchange.
Power-flow and screening tools
PowerWorld Simulator covers steady-state security and generator interconnection studies, with ATC and PV and QV curves. PowerGEM’s TARA runs N-1 and N-1-1 contingency analysis with a Python API. Siemens pairs PSS E with PSS MOD to automate generation interconnection workflows and data submission, and exposes more than 2,000 open Python APIs. gridmo keeps maintained grid-code templates for PSS/E, PSCAD and PowerFactory.
Site screening and flexible connection
PVcase Prospect models interconnection capacity and allocated costs for US sites, and Kevala edits queued resources inside scenario models. Smarter Grid Solutions sells real-time controls so distribution utilities can connect more generation, storage and large loads within grid limits.
