Training & Tutorials — Introduction

Start here for a quick overview of Gridtwin CMS and the interconnection map.

Data Sources and Links

Gridtwin provides transparency into the data sources used for map layers and interconnection analysis.

• View data sources under Help and Support
• Browse state-specific data layers
• Access links to original public data sources
• Contact support to request additional map layers

Steps

1. Navigate to Help & Support → Data Sources
2. Locate the dataset of interest
3. Follow links to original sources
4. Check timestamps and versions
5. Request additional layers if needed

Advanced Interconnection Estimates and Options

Modify project geometry and assumptions to analyze multiple interconnection scenarios.

• Edit project boundaries and points of interconnection
• Manually draw three-phase line extensions
• Analyze multiple interconnection routing options
• Run separate analyses for each scenario

Steps

1. Open a project site to edit geometry
2. Add or adjust candidate POIs and routes
3. Create multiple scenario variants
4. Run estimates for each scenario
5. Compare costs and select a path

Overriding Local Capacity Values

Advanced users can override published feeder and substation values to test alternative planning assumptions.

• Override feeder hosting capacity values
• Adjust connected and pending distributed generation
• Override substation capacity and protection thresholds
• Understand how overrides affect required upgrades

Steps

1. Open My Projects → Select Results → Edit
2. Choose feeder or substation values
3. Edit fields within allowed ranges
4. Save and publish overrides
5. Re-run analyses with new assumptions

Cost Adjustments and Sharing

Incorporate contingency, taxes, and shared upgrade assumptions into interconnection estimates.

• Add contingency as a percentage of total cost
• Apply tax assumptions to project estimates
• Include 3V0 cost sharing between multiple developers
• Compare adjusted costs across scenarios

Steps

1. Open My Projects → Select Results → Edit
2. Add contingency percentage
3. Apply tax assumptions if applicable
4. Configure 3V0 cost sharing
5. Save and compare adjusted totals

Advanced Parcel Searching Tools

Advanced search tools allow users to define custom search areas and perform map-based filtering.

• Define and save custom geographic search areas
• Search across towns, regions, or custom boundaries
• Filter parcels using map-based criteria
• Edit or delete saved search geometries

Steps

1. Define a custom search area on the map
2. Add attribute filters and layer masks
3. Run the search to generate candidates
4. Save or export the result set
5. Refine filters and rerun as needed
