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. A detailed engineering design cost study determines 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 moment in time and updated annually, and 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 interconnection process.
More informative and site specific information on hosting capacity is offered in the following order:
- Information on other projects in the interconnection queue for various feeders, but not yet interconnected, may have an impact on hosting capacity. This information is not reflected in the maps because we lack certainty on whether the projects will proceed. You may use this information in conjunction with the maps and with the Pre-Application below. This interconnection queue information is available on-line under the Substation DG Queue prompt on this page.
- You may make a Pre-Application Report data request for a specific location as set forth in our Minnesota Section 9 tariff, at sheets 68.13 – 68.14. The fee for this is $300.00. For more information on obtaining a Pre-Application see the discussion about Pre-Application Requests on this page.
- You may submit a formal request for interconnection at a specific site. For more information on submitting a formal request for interconnection see this page. After your application is determined to be complete, and you pay the applicable fees, we will perform any necessary screening or study specific to that location and generation size and type, and where applicable offer an interconnection agreement under our applicable tariffs. If a study is required, and Xcel Energy system modifications are found to be necessary, the study results will contain an indicative cost estimate for our work in building out our system to accommodate your distributed generation. Smaller sized systems typically do not need these studies or system modifications. If the distributed generation system is under 250 kW and not subject to other restrictions, the Uniform Statewide in our Section 9 tariff may be used in lieu of the Section 10 interconnection agreement.
- After the Section 10 interconnection agreement is signed and funded, and if system modifications are required, the Company will perform a detailed engineering design cost study with a more specific estimate of the Company’s costs to build out the system to accommodate the interconnection. You will have the opportunity to cancel the interconnection agreement before the Company starts to do the build out and before it starts to incur significant costs. You will be responsible for the actual costs incurred by the Company.
