GridSim re-runs full ERIS and NRIS study methodology under your own assumptions, so you can see exactly how a site holds up before you put capital behind it. This is the product you have known as the Local Studies Tool.
methodology replicated
the same ISO engines
Bring your view of queue drop-offs, retirements, and planned transmission upgrades into the model, and apply it to the sites you care about.
GridSim runs the same ERIS and NRIS methodology the ISOs use, in the same software, so the upgrades it surfaces are the ones you would actually be assigned.
Add competing projects and new loads, then watch how a site’s results change. Run a hundred what-if scenarios before your decision point.
See the specific constraints and network upgrades a project triggers, so you can explain the result and act on it with confidence.
Toggle queue drop-offs, retirements, and planned upgrades, then re-run the study. GridSim applies your assumptions to the full ISO methodology, so the results reflect the grid as you expect it to be.
Test how a competing generator or a large load at a nearby point of interconnection changes your available capacity and which constraints it triggers, so your timing and siting decisions reflect the queue around you.
GridSim runs the full ERIS and NRIS injection study rather than a shortcut, and returns accurate results quickly enough to iterate, so you are not waiting weeks for each consultant pass.
Stack scenarios next to each other to see how each site performs under different futures, so you advance the projects that hold up and disqualify the ones that do not.
