Minnesota Power, an ALLETE Company

• A SISA is an agreement for MP to study the impacts of the request and identify interconnection and network upgrades required by the requested interconnection; all costs for the study shall be paid by the Requestor.
• Transmission Owner will draft and send an initial SISA to Requestor.
• Initial cost estimate for the System Impact Study (SIS) is $10,000 plus $50 per megawatt of load proposed to be interconnected.
• Within 60 business days of execution of SISA, Requestor will be invoiced for 50% of the estimated costs with payment due within 30 business days.
• MP will utilize its best efforts to complete the SIS within 90 business days (or timeline as otherwise agreed to by Parties) of deposit receipt.
• Once SIS is completed and delivered, remaining cost balance will be invoiced to Requestor and payment due within 60 business days.
• Following receipt and finalization of completed study, Requestor will have 15 business days to decide whether to proceed with a Facilities Study (FS) for interconnection and network upgrades identified in the SIS. If the Requestor hasn’t executed the Facility Study Agreement within 45 calendar days of being presented with the Facility Study Agreement, then the original interconnection request will be considered withdrawn. Further consideration would then require the Requestor to resubmit the interconnection request.

• An FSA is an agreement for MP to identify the scope, schedule, and estimated cost for the interconnection and network upgrade facilities required by the requested interconnection; all costs for study shall be paid by the Requestor.
• Transmission Owner will draft and send an initial FSA to Requestor.
• Initial cost estimate of the Facility Study (FS) is $25,000 plus $250 per megawatt of load proposed to be interconnected by the Requestor.
• Upon execution of FSA, Requestor will be invoiced for 50% of the estimated costs with payment due within 30 business days.
• MP will utilize its best efforts to complete the FS within 90 business days (or timeline as otherwise agreed to by Parties) of deposit receipt.
• Once FS is completed and delivered, remaining balance will be invoiced to Requestor and payment due within 60 business days.

The completed FS shall be valid for a period of 180 calendar days, at the end of which if a Facilities Construction Agreement (“FCA”) has not been executed or filed, the interconnection request shall be terminated, unless extended by mutual written agreement.

• An FCA is an agreement for the customer to pay for, and Minnesota Power to construct, the interconnection and network upgrade facilities.
• An Engineering and Procurement Agreement (E&P) is an agreement which may be utilized to initiate engineering, procurement, and other development activities for the interconnection and network upgrade facilities prior to executing an FCA. The purpose of an E&P Agreement is to begin the study and procurement activities prior to the execution of an FCA which may help a customer achieve a desired in-service date.
• All costs, schedules, and payment terms for the FCA and optional E&P will be spelled out in the Agreements sent to the Requestor. Minnesota Power will self-fund the Network Upgrades that are identified in FCA. (More information on self-funding can be found in the MISO Tariff. FERC has authorized the MISO self-funding model to be applied in non-generator interconnection applications in the MISO footprint. See e.g., FERC Docket Nos. ER23-40 and ER23-2609.
• Additional studies or agreements may be required based on the characteristics of the interconnection that is requested. Projects will not be submitted into the MISO transmission planning process until they have a signed FCA.

• Identifies the obligations of each Party in the interconnection process.
• Governs the ongoing ownership and operation of the Parties’ facilities and equipment at the new interconnection.
• Costs associated with the interconnection have been identified in the previous steps of the interconnection process.
