Grid Aggregations: Behind the meter solar or large numbers of Utility Scale sites

Solar visibility for markets and networks

Improve load forecasting, manage your network, or beat the market. Solcast Grid Aggregations pair up our rapid update, global cloud nowcasting system with your PV installation data to provide live, forecast and historical estimates of total distributed solar power output.

Useful for solar assets of all sizes, including behind-the-meter PV, Grid Aggregations are organised by your areas of interest. Choose postcode/zipcodes, market regions or network assets (e.g. zone substation), and we’ll create a unique API endpoint for each.

Register for a free commercial user account on our API Toolkit and view live samples of one of the 1000+ aggregations we have running live globally. From the API Toolkit, you’ll be able to work with Solcast to quickly create your own under a free trial.

The API Toolkit is our user-friendly way of exploring our data, where you can watch you Grid Aggregation forecasts change in with each Rapid Update and review the API requests available for downloading the data.

Installed Solar Metadata Requirements

Setting up your Grid Aggregation is very straightforward. Once you’ve created your API Toolkit account, locate the Grid Aggregations section of the landing page and click “Request to trial a new Grid Aggregation”.

You’ll need to provide us:

• A region definition (geographic area, postcodes/zipcodes, or a specific shapefile) AND the total Installed PV capacity, OR
• An itemised list of each PV site location and its capacity
