The hosting capacity map display is a high-level estimate of the available hosting capacity for adding distributed generation. Hosting capacity is defined as the amount of generation that can be accommodated at a point on the distribution system without requiring mitigations such as specialized inverter settings or infrastructure upgrades. This map is one tool you may use to help assess the available hosting capacity in a given general location.

The determination of the amount of generation that can be accommodated at a point in the distribution system can include several steps, with more specific and more accurate information becoming available as the effort and expense to provide that more specific information increases. Based on the size of the proposed project and other qualifying factors, different review and study processes in the Minnesota Distributed Energy Resources Interconnection Process (MN DIP) determine the exact amount of generation that can be accommodated at a given location as well as the mitigations required to interconnect the generation capacity under review. The hosting capacity map is offered free of charge and correspondingly is not as accurate as the next steps for obtaining more specific information. Also, the map is taken from data as of a point in time and updated as of the date indicated in the pop-up display on the map, and therefore may not reflect current conditions in a given area. The map is being provided for informational purposes only and is not intended to be a substitute for the established MN DIP interconnection process.

Additional information or tools to aid your consideration of potential hosting capacity is available on our website under the How to Interconnect section:

1. Distributed Energy Resources (DER) Interconnection Queue

DER projects in the interconnection queue that have not yet been interconnected may have an impact on available hosting capacity. The hosting capacity map and tabular results reflect DER projects that were in-service as of the date indicated in the pop-up on the map. Projects in the DER interconnection queue that are pending or that went into service after this date are not reflected in the hosting capacity map. So, using the queue information in conjunction with the hosting capacity map and tabular results will provide you with an updated view of potential hosting capacity for specific portions of the distribution system. This interconnection queue information is updated monthly and available under the Public Distributed Energy Resources Queue prompt on this page.

Pre-Application Data Report

You may also choose to make a Pre-Application Report request for a specific location. The Pre-Application Report is a preliminary screen of a specific site on the distribution system that is based on existing, available distribution system data without any field verification. The fee for the Pre-Application Report is $300.00. For more information on obtaining a Pre-Application Report, see the request form and additional discussion under the Pre-Application Report prompt on this page.

DER Interconnection Request

Finally, you may submit a formal request for DER interconnection at a specific site. More information on submitting an interconnection application under the MN DIP is provided under the Application Engineering Process as well as Technical Requirements and Resources prompts on this page.

Energy Saving Tip

Create your own shade by planting a tree in a strategic location in your yard to block sunlight from pouring into your windows. It doesn't get much more green than a tree!

Break Ground, Not the Law

Always call 811 before digging in your yard to avoid hitting buried gas or electric lines. Not only is it the safe thing to do, but it's the law.
