Integrated Resource Plan (IRP) Filing Requirements

Application Instructions for Integrated Resource Plan filing

These application instructions apply to an electric utility application for Integrated Resource Plan under the provisions of MCL 460.6t. The application shall be consistent with these instructions, with each item labeled as set forth below. Any additional information considered relevant by the applicant may also be included in the application.

1)Schedule

A utility shall coordinate with the Commission Staff in advance of filing its IRP application to avoid resource challenges with IRP applications being filed at the same time as IRP applications filed by other utilities. A utility may be requested to delay its IRP application in order to preserve a 21day spacing between IRP applications.

MCL 460.6t(3) specifies that the initial IRP applications be filed within two years of the effective date of the act and also requires the Commission to issue an order establishing filing deadlines. The proposed initial IRP application filing deadlines are:

I)Upper Peninsula Power Company: May1, 2018 (or earlier as requested)

II)Indiana Michigan Power Company: December 14, 2018 (to align with Indiana)

III)Consumers Energy: January 4, 2019 (or earlier date if requested and spaced at least 21 days apart from other IRP cases)

IV)Wisconsin Electric Power Company: January 25, 2019

V)Northern States Power Company Wisconsin (Xcel): February 15, 2019 (to align with Minnesota)

VI)Alpena Power Company: March 8, 2019

VII)UMERC: March 29, 2019

VIII)DTE Electric: April 19, 2019

Following the initial IRP applications, the utilities shall comply with all future filing deadlines directed by the Commission and shall continue to coordinate with Staff to schedule its future IRP application filing dates.

2)Filing Announcement:

In order to facilitate the scheduling and preparation of IRP proceedings, any utility intending to file an IRP shall file a Filing Announcement (FA), in a new docket, at least 30 calendar days prior to the proposed filing of the case. The FA, along with a proof of service, shall be served on the Michigan Public Service Commission (Commission) and all parties granted intervention in the utility’s last IRP case, and the utility’s last rate case. If the IRP described in the FA is not filed within 120 days after filing of the FA, the FA will be considered withdrawn. If a certificate of necessity (CON) is also being filed, the same FA would serve as the FA required for the CON.

I)The Filing Announcement shall include:

a) Statement of intent to file an IRP

b) Estimated date of filing

c) Information related to any stakeholder engagement meetings that have already taken place or are scheduled to take place.

d)Information related to any CON application that would be filed with the utility’s IRP.

The Commission may, if necessary, order a delay in filing an application to establish a 21-day spacing between filings. The “Filing Announcement” is submitted at least 30 calendar days prior to the IRP application, thus providing the Commission with sufficient time to issue an order regarding the 21-day spacing if it so chooses.

II)Pre-filling RFP

Each electric utility whose rates are regulated by the commission shall issue a request for proposals to provide any new supply-side generation capacity resources needed to serve the utility’s reasonably projected electric load, applicable planning reserve margin, and local clearing requirement for its customers in this state and customers the utility serves in other states during the initial 3-year planning period to be considered in each integrated resource plan to be filed, as outlined in MCL 460.6t.

a)Documentation supporting the RFP process that took place shall be included with the IRP application.

b)The RFP process undertaken by the utility is subject to audit by the Staff.

c)The application shall include evidence that the pre-filing RFP process was conducted in a manner consistent with MPSC code of conduct, and applicable state, federal, and MPSC rules.

IV)The utility’s Quinquennial IRP filings shall demonstrate compliance with MCL 460.6t and include the following items:

a)Letter of transmittal expressing commitment to the approved preferred resource plan and resource acquisition strategy and signed by an officer of the utility having the authority to bind and commit the utility to the resource acquisition strategy;

b)Technical volume(s) that fully describe and document the utility’s analysis and decisions in

selecting its preferred resource plan and resource acquisition strategy.

c)The data and information requested in the MPSC’s IRP Filing Requirements included herein.

d) Any other information deemed relevant by the applicant.

1)Stakeholder Process.

Stakeholder engagement early in the development of the IRP is encouraged, to (1) Educate stakeholders on utility plans; (2) Improve transparency of utility decision making process for resource planning; (3) Create opportunity to provide feedback to the utility on its resource plan; (4) Encourage robust and informed dialogue on resource decisions; and (5) Reduce utility regulatory risk by building understanding and support for utility resource decisions. The utility may choose to incorporate some, or all, of the stakeholder input in its analysis and decision-making for the Quinquennial IRP filing.

I)Pre IRP filing:

In the year prior to the Quinquennial IRP filing, each electric utility shall consider hosting Quinquennial update workshops with stakeholders.

a)The purpose of the pre filling workshop(s) is to ensure that stakeholders have the opportunity to provide input and to stay informed regarding the:

iAssumptions, scenarios, and sensitivities.

iiProgress of Utility’s the IRP process.

iiiPlans for implementation of selected resource strategy.

II)Documentation demonstrating the stakeholder engagement process undertaken by the utility shall be included with the IRP application. Documentation may include:

iWorkshop dates

iiEvidence that notice of the workshops was provided to the public

iiiMeeting minutes

ivMeeting or workshop attendance lists

vStakeholder comments on the draft IRP

viDiscussion indicating if or how the stakeholder process influenced the IRP

III)The utility shall prepare a stakeholder report to document the outcomes of any pre-filing workshops, and shall file the reports with the Quinquennial IRP filing.

IV)Stakeholders may file comments with the Commission concerning the utility’s stakeholders report within thirty (30) days of the utility’s IRP filing or submission.

2)Risk Assessment Methodology.

The IRP application should include evidence that a thorough risk analysis was undertaken as part of the IRP. Acceptable forms of risk analysis include, but are not limited to the following:

I)Scenario analysis: For non-market-based policy instruments, such as targets, standards, or regulations, scenario analysis is one the simplest ways to explore the decision landscape under alternative futures. Modelers should strongly consider the methodological heritage of various scenario approaches, ensure consistency among scenario assumptions, and carefully consider the limitations and caveats associated with the analysis while drawing insights

II)Global sensitivity analysis: Market-based policy instruments rely on robust policy designs under uncertainty. Global sensitivity analysis should be applied wherever possible to test the robustness of model results and insights. Sensitivity analysis can help determine whether a single input parameter value, combination of parameter values, or a structural assumption built into the model are driving the results and help focus scenario analyses.

III)Stochastic optimization: Stochastic optimization should be considered when the goal is to explore optimal near-term planning strategies that hedge against future uncertainty. The curse of dimensionality limits the number of uncertain parameters that can be included, so modelers should also consider uncertainty that is omitted from the event tree.

IV)Generating near-optimal solutions: MGA can produce alternative solutions that perform well with regard to the modeled objective but are very different in decision space, it should be considered when analysts or decision makers wish to consider a wide range of alternatives. MGA can also be used to test the flexibility of the base solution within a user-specified cost range.

V)Mean-Variance portfolio Analysis:

3)Confidential information.

Transparency and the use of data that can be shared with the Commission, Staff, and intervenors is encouraged. Proprietary,confidential,andothernonpublicmaterialsusedinthedevelopmentoftheforecasts,scenarios,orotheraspectsoftheIRPshouldbepresentedinsuchawaythattheproprietaryandconfidentialnatureofthematerialsispreserved.The use of publically available data and materials is encouraged in lieu of proprietary and confidential materials whenever possible.

Upon Staff’s request, the utility shall make available to Staff any proprietary information, analyses, modeling, or similar that the utility uses to support its filing or that the utility uses to facilitate its internal planning, modeling, decision-making, risk assessment, or similar processes. If a utility is unable to provide the requested proprietary information due to license/contractual/legal restrictions, the utility shall provide staff with verification of such restrictions.

4)Approval of Costs
