Our capacity data is based on a power flow model which makes assumptions about future events. As such, it is intended as an early-stage estimate and is not meant to replace later-stage interconnection studies that will provide an updated and more comprehensive assessment of available capacity.
In this article, you'll learn how to:
- Search for Parcels with Capacity in the Map
- View Substations with Available Capacity in the Map
- Review Interconnection Data in a Report
- Filter and Export Interconnection Data in a Report
For more information on Interconnection data, please contact your Transect Customer Success Manager.
Using Interconnection to Search for Parcels
With the Parcel Filter, you can easily locate parcels with specific infrastructure attributes. Here's how to get started:
- Navigate to the Map from the top of any page.
- From the "Parcel Filters" menu, select the Proximity option.
- Within the pop-out, input the parameters of your search. Options include:
- Distance to Transmission Lines
- Transmission Line Voltage
- Line Owner [Contains]
- Distance to Substations
- Minimum Bus Voltage
- Minimum Injection Capacity
- Minimum Withdrawal Capacity (ERCOT only)
- Optionally, you can toggle the layers for Transmission Lines or Substations to view them in the Map.
- When finished, select Apply Filters.
Parcels that do not meet your specified criteria will automatically be excluded from view, leaving only relevant parcels visible.
Viewing Substations with Available Capacity
Organizations with access to the Interconnection feature will also have access to both the Injection Capacity and Withdrawal Capacity (ERCOT only) layers. First, add these layers to the Map, and then check the box to activate the applicable layer. To view more information, simply right-click that feature on the Map. Please note that only one of these layers can be activated at a time.
The colors shown on the map indicate the following capacity:
The colors shown on the map indicate available capacity levels. This color-coding applies to the average capacity available across multiple years and scenarios. For example, if one scenario shows a capacity of 10 MW and another shows 100 MW, the color would reflect the average (e.g., Red for <50 MW). We recommend always confirming specific data in the Interconnection table.
Reviewing Interconnection Data within a Report
“Nearest Substation” Card
Once a report is generated, the Executive Summary displays a card for the "Nearest Substation." This includes the distance, maximum injection capacity, maximum withdrawal capacity (ERCOT only), and the nearest transmission line. Click View Details for more information.
Interconnection Page
For more detailed data, you can click View Details in the "Nearest Substation" card (shown above), or select Interconnection from the left-side menu. This page provides a comprehensive analysis of the local grid infrastructure, including the owner, name, distance, voltage, and winter/summer capacity (MW) for all substations and transmission lines within 10 miles of your project.
You can also view:
- Capacity Information
Select your preferred capacity tab or select a substation to view it directly in the Report Map.
- Transmission Line Data
View the name, distance from the Area of Interest (AOI), and voltage of nearby lines.
- Interconnection Queue Data
At the bottom of the Interconnection page, you'll find Interconnection Queue Data for projects in the same county as your AOI. This data, provided by the ISOs, includes the owner, capacity, status, projected COD and additional information about projects that are close to your area of interest.
- The acronyms under “Status” vary by how each ISO reports them. In ERCOT, for instance, the statuses mean:
- SS: Screening Study (started or completed)
- FIS: Full Interconnection Study (started or completed)
- IA: Interconnection Agreement (IA = executed, No IA = not executed)
- The acronyms under “Status” vary by how each ISO reports them. In ERCOT, for instance, the statuses mean:
Our power flow model only considers projects with an executed Interconnection Agreement, as these are likely to be constructed and thus can affect capacity forecasts.
Filtering Interconnection Data
You can filter Interconnection information in the following ways:
- By Years (Capacity Only):
- Select Add/Edit Years in the upper right corner of the capacity table.
- Check the applicable years you’d like to include/exclude. The table will automatically reflect your changes.
- By Column:
- Sort: Click the arrow to sort ascending/descending.
- Filter: Click the filter icon in any column and enter your criteria. Your table will be filtered automatically. Select Clear Filters to remove any applied filters.
Exporting Interconnection Data
You can export transmission or interconnection queue data by clicking Export as CSV in the upper right corner of the applicable data table.
