Hosting capacity maps in PVcase Prospect help you efficiently site distributed generation projects by visualizing and filtering grid infrastructure based on available capacity.
Understanding hosting capacity maps
Hosting capacity maps display the ability of the electric grid to accommodate additional distributed generation without major upgrades. Utilities provide these maps, but their format, update frequency, number of layers, and metadata can vary. For example, some maps are updated monthly while others only annually, and some include zoom restrictions requiring users to zoom in to view all grid assets.
Working with different map types
There are three main map types in PVcase Prospect:
- Line layers: Use the add grid sidebar or add grids directly from the layer catalog. Select a grid type and a source utility, then filter for criteria such as location or capacity. Add selected grid segments to your project, which will populate both the map and project table.
- Polyline layers: Use the search around functionality to identify relevant assets near your area of interest.
- Polygon layers: Use the Union of geometry tool to combine multiple capacity polygons into a larger area, then run a parcel search within that new boundary. This helps identify parcels with suitable hosting capacity.
Filtering and adding assets
Regardless of the map type, use filters to narrow down grid assets by parameters such as location, load capacity, or other metadata. You can apply multiple filters to refine your selection, and then add assets in bulk to streamline your workflow.
When working with line layers, remember that utilities often display lines as short segments (pole-to-pole), so you may see many small segments on the map.
Integrating parcels and substations
After adding grid infrastructure, you can use the parcels layer to identify land parcels under areas with available capacity and gather owner information for outreach. Similarly, add substations to your project by selecting from the layer catalog or using polygon tools to select multiple substations.
Best practices
- Use the appropriate tool for the map type (add grid, search around, or union of geometry).
- Apply filters and bulk selection to streamline your workflow.
- Use map tools to create custom areas, add relevant grid layers, and integrate land parcels and substations.
- Always check for map-specific details like zoom restrictions and update frequency.
