Developing FERC-Compliant Heat Maps For A Large Utility Company

Discover how CartoVista developed an innovative mapping application for one of the largest utility companies in the United States.

heat map hero


One of the largest utility companies in the United States enlisted CartoVista’s expertise for their new heatmap application project and develop FERC-compliant public generator Interconnection Queues and Capacity Heat Maps, greatly enhancing access to interconnection information for developers.

In a collaborative effort, CartoVista designed a custom interactive application through a series of Joint Application Design (JAD) sessions with the client. This process ensured a tailored tool that allows users to visually identify potential generation interconnection points, with a graphical interface displaying the estimated capacities on the client’s transmission system.

Introduction to the Heatmap Application

1. Current Queue Activity Map

This map provides a dynamic overview of ongoing activities within the project queue, offering up-to-date insights for effective management and planning.

queue map
poi map

2. Point of Interconnection (POI) Analysis Map

Tailored for analyzing potential interconnection points on the grid, this map is an essential tool for detailed capacity and feasibility studies.

Both these maps are integrated with a standard base map. This base map was meticulously designed to encompass the full geographic extent of the client’s operational areas, while also reflecting the company's brand identity.

Current Queue Activity Map

The Current Queue Activity Map provides detailed insights into the current status of queue activities. This map is designed to be highly interactive, enabling end users to visualize and comprehend the queue data across various metrics and scenarios. Key features of this map include:

fuel type

Fuel Type

Users can filter and view projects based on the type of fuel used, such as natural gas, solar, wind, etc. This helps in understanding the energy mix within the queue.

interconnecting utility

Interconnecting Utility

The map allows for the identification of projects based on the utility they are seeking to connect with, offering insights into the distribution of projects across different utilities.

Request status

Request Status

This feature displays the current status of each request in the queue, such as pending, approved, or denied, enabling users to track the progress of various projects.



Users can view projects based on the type of service that facilities have applied for (ERIS, NRIS, etc.)

total NW

Total Net MW

This metric shows the total net megawatt capacity of each project in the queue, providing a sense of the scale and impact of each project.

incremental NW

Incremental Net MW

This feature allows users to see the incremental net megawatt capacity added by each project, offering insights into how each project contributes to the overall capacity of the grid.

Point of Interconnection (POI) Analysis Map

The POI Analysis map displays a heat map that correlates to potential available capacity on the system and allows end users to perform a MW request analysis from specific POIs (points of interconnection) on the map.


Scenario Analysis

The Scenario Analysis feature in the application offers users an advanced method to model and visualize different grid capacities:

Year and Scenario Selection – Users can choose a specific year and scenario to simulate various grid capacity situations. This flexibility allows for a thorough analysis of how the grid might evolve or react under different conditions in the future.

Visual Heatmap Display – Upon selecting a year and scenario, the application dynamically generates a heatmap that visually represents the capacity in the client’s system. This visual tool is invaluable for understanding the spatial distribution of grid capacity.

Customizable Display Options

kV Levels: The interface’s kV Level switches allow users to choose voltage levels for analysis, alongside the year and scenario. By default, all levels are selected. Choosing a specific level filters Points of Interconnection accordingly, updating the heatmap. This capability is crucial for precise capacity analysis, enabling informed decisions with detailed data.

Layer Control: Users have the flexibility to tailor their view on the POI Analysis Map by toggling various layers. This includes switching on or off the points of interconnection layers, capacity heatmaps, and the current queue activity.

User-Friendly Search Functionality

The Search feature in the app improves user navigation by enabling precise location searches using different geographic criteria. It helps users find specific areas on the map quickly and efficiently, catering to diverse search preferences.

  1. County Name and State: Users can enter the name of a county along with the state to focus the map on that particular county, facilitating regional analysis.

  2. City/Place Name: Typing in the name of a city or a place zooms the map directly to that location, providing a more localized view.

  3. Postal Code: Users can search using postal codes, a useful feature for pinpointing areas when the exact address or place name is unknown.

  4. Address: For more precise location targeting, entering a full address brings up the exact spot on the map.

  5. Latitude, Longitude Coordinates: For users who have specific geographical coordinates, inputting latitude and longitude details offers the most precise location-finding capability.

These varied search options significantly enhance the usability of the map, allowing users from different backgrounds and with different needs to effortlessly navigate to their area of interest.


Easy To Export

The Scenario Analysis feature in the application offers users an advanced method to model and visualize different grid capacities:

Multiple Formats: The application facilitates easy export of maps in both PNG and Adobe PDF formats.

Versatility in Usage: These export options make it convenient for users to incorporate the maps into presentations or share them with other stakeholders, enhancing communication and collaborative efforts.

Effective POI Analysis

2. POI Search Functionality

Users have the option to search for a POI by name, enhancing ease of navigation. request min

3. MW Request Analysis

Users can conduct a POI analysis by entering the desired number of megawatts (MW) for that interconnection.

4.impact min

4. Impact Calculation and Visualization

After entering the MW request, the application calculates its impact on the system. An updated heatmap is generated showing the injected MWs, and a detailed table provides insights for the selected POI. For POIs with overloaded lines, additional data like Transfer Distribution Factor (TDF), MW impact, and line loading percentages are displayed.

5.color coding min

5. Dynamic Color Coding

POIs on the map change color based on the status of the analysis, such as Normal Load or Overload, providing a quick visual reference.

6.culmulative impact min

6. Cumulative Impact and Overlay Options

If multiple locations are selected in a session, the results table and heatmap reflect the cumulative impact. Users can also overlay the Current Queue activity layer for a more comprehensive analysis.
