Illinois Power Marketing Company seeks compensation for congestion charges resulting from MISO’s alleged incorrect, reverse definition of a flowgate from MISO into PJM on December 29, 2016, which caused the Duck Creek unit to be dispatched higher by PJM and to incur high congestion costs. Big Rivers Electric Corporation seeks relief from reduced dispatch, and lower day-ahead prices, of its Wilson unit due to heavy congestion from April 7-22, 2017, which allegedly resulted because MISO’s next-day and day-ahead models did not promptly reflect a new combined-cycle plant that became operational on April 7, 2017. Uncia Energy, LP – Series A seeks compensation based on its claim that a particular transmission constraint was not relieved when, pursuant to Schedule 28A of MISO’s Tariff relating to Transmission Constraint Demand Curves (“TCDCs”), MISO made temporary overrides of the Marginal Value Limits (“MVLs”) in multiple hours in the Real-Time Market on February 19-20, 2017 to relieve the constraint. 05/05/17 Pending Pending Pending 06/14/17 Pending Pending Pending 07/19/17 Pending Pending Pending 07/20/2017 Party Requesting ADR Great River Energy Page 2 of 12 Date Dispute Received by MISO 01/05/16 Nature of the Dispute Great River Energy (“GRE”) seeks compensation relating to allegedly improper mitigation of Real-Time Revenue Sufficiency Guarantee (“RSG”) Make-Whole Payments for three separate events on January 7, 2014 and February 10, 2014.

Date Request for ADR Posted on Web 02/13/15 Wisconsin Electric disputes the calculation of variable compensation and compensation during a test of its Presque Isle Power Plant under a System Support Resource Agreement with MISO. DC Energy Midwest, LLC seeks to recover the value of FTRs acquired at the 2013/2014 Annual FTR Auction, and the Jan. and Feb. 2014 monthly auctions, claiming that the associated Interface Commercial Pricing Nodes were defined a certain way at the auctions, but that MISO settled the FTRs based on a subsequent redefinition of such nodes. Entergy Arkansas, LLC seeks compensation in the form of makewhole payments for its units that were manually redispatched on December 9 and 21, 2014. 03/17/15 Entergy Arkansas, LLC seeks compensation in the form of makewhole payments for one of its units manually redispatched on April 27-28, 2014. 12/04/15 03/17/15 05/20/15 Resolution of the Dispute Following discussions with management officials, MISO granted DTE’s request for reimbursement of Schedule 17 charges on DTE’s Ludington Pumped Storage Facility for the period June 1, 2011 to August 19, 2014 and September 30 to October 17, 2014. Following discussions with management officials, MISO partly granted Wisconsin Electric’s ADR request (i.e., regarding the use of Actual Energy Injections to determine variable compensation and to compensate any must-run energy). Following discussions with management officials, MISO disagreed with DC Energy’s position that the redefinition of the SPP Interfaces was inappropriate, and that the redefinition should not have been applied to DC Energy’s FTRs. Following discussions with management officials, MISO granted Entergy Arkansas equitable relief during certain hours of Manual Redispatch. MISO will file a request for waiver of its Tariff seeking FERC authorization in order to implement such relief.

Exelon seeks compensation relating to alleged improper control mode signals on January 25-26, 2014. Wolverine seeks compensation relating to Real-Time Revenue Sufficiency Guarantee Make Whole Payments that were mitigated on February 24, February 28, March 3 and March 6, 2014. Date Request for ADR Posted on Web 06/10/14 06/26/14 06/11/14 Resolution of the Dispute Following discussions with management officials, MISO determined Entergy Louisiana should be compensated for the operation of its Ninemile 5 Generating Unit based on its real-time dispatch. Following discussions with management officials, MISO granted Exelon relief because zero control mode signals resulted from MISO’s premature replacement of ICCP links. Following discussions with management officials, MISO deemed it appropriate under the circumstances to grant Wolverine Real-Time Revenue Sufficiency Guarantee (“RSG”) makewhole payments that would have resulted based on updated cost information it had tried to upload, consistent with the MISO Tariff’s RSG-related provisions, and the underlying principle of ensuring that Generation Resources are made whole to their cost of operation.

Vitol seeks a determination that the Commercial Pricing Node definitions MISO used to award monthly and annual FTRs at certain nodes be used to settle the corresponding FTR positions obtained by Vitol in the monthly and annual auctions, which would allegedly reduce the amounts owed by Vitol for the months of March – May 2014. NRG Power Marketing LLC seeks recovery of the hedging value allegedly lost by FTRs it purchased in the 2013/2014 Annual FTR Auction, and the November 2013 Multi-Period Monthly Auction due to the subsequent redefinition or “collapsing” of MISO South’s Interface CPNodes. Date Request for ADR Posted on Web 07/14/14 Resolution of the Dispute Following discussions with management officials, MISO granted Dow Chemical relief for costs incurred because automatic midnight reversion to normal equipment default ratings on several dates unduly caused binding constraints that resulted in significantly negative LMPs. Status of Resolution of Informal Negotiations (Granted) Date Resolution Posted on Web 01/08/15 07/03/14 Following discussions with management officials, MISO disagreed with Vitol’s position that the redefinition of the SPP Interfaces was inappropriate, and that the redefinition should not have been applied to Vitol’s FTRs. (Denied) 12/05/14 08/14/14 Following discussions with MISO management, MISO denied NRG’s ADR request, finding that (i) the redefinition of the MISO South Interface CPNodes was appropriate and (ii) the redefinition was properly applied to NRG’s FTRs.

(“MISO”) Informal Requests and Resolutions of Alternative Dispute Resolution Pursuant to Attachment HH (Dispute Resolution Procedures) of MISO’s Tariff and ADR Business Practices Manual Party Requesting ADR Exelon Generation Company, LLC Date Dispute Received by MISO 09/03/14 Nature of the Dispute Exelon seeks relief from allegedly improper mitigation of its combined cycle facility below its production costs during certain Operating Days in December 2013 and January, February, and March 2014. Date Request for ADR Posted on Web 10/09/14 New Ulm Public Utilities (NUPUC) 10/10/14 NUPUC seeks compensation for its unit’s emergency dispatch on March 4, 2014, for which MISO allegedly received incorrect meter data. 11/20/14 Union Electric Company (d/b/a Ameren Missouri) 10/21/14 Ameren Missouri seeks correction of an alleged under-allocation of ARRs for 2014-15 that it claims is due to MISO’s receipt and use of EMS model substation load information. 11/20/14 DC Energy Midwest, LLC 10/22/14 DC Energy Midwest, LLC seeks restoration of FTRs that it purchased in the 2014/2015 Annual FTR Auction on paths between points modeled inside and outside of MISO South, and that MISO subsequently nullified as Same-Bus FTRs. 11/07/14 Resolution of the Dispute Following discussions with management officials, MISO determined that Exelon’s Frontier generation facility (i) was correctly mitigated on certain dates, (ii) should be excused from mitigation on two dates, and (iii) should have mitigation reduced on some dates. Following discussions with MISO management, MISO partially granted NUPUC’s Request for ADR. Such relief excludes amounts that exceed the applicable Reference Level and that relate to start-up costs for which the unit is not eligible. Following discussions with MISO management, MISO partially granted Ameren Missouri’s Request for ADR. MISO concluded it would be reasonable and equitable to grant Ameren relief for the reduction of Stage 1B ARR allocations attributable to the unsuitable load data to model the Franklin substation’s load. MISO also determined that no relief is warranted for the reduction in allocation due to relevant transmission constraints, and ARR nomination patterns. Following discussions with MISO management, MISO denied the ADR request because the FTRs involved sources and sinks that are physically in the same electrical location, and as such are Same-Bus FTRs.

Big Rivers Electric Corporation seeks recovery of overcharges allegedly resulting from an inaccurately calculated Marginal Congestion Component of the DayAhead Locational Marginal Price at the BREC.CENTURY Pricing Node on August 8, 9, 15, 18, 19 and 20, 2014. Date Request for ADR Posted on Web 12/05/14 02/13/15 Resolution of the Dispute MISO and DC Energy have reached an informal resolution of DC Energy’s dispute regarding MISO’s rejection of, and untimely refund of the price of, certain FTRs that cleared in the 20142015 Annual FTR Auction at a positive price based on the consistent modeling of the relevant CPNodes in the Day Ahead and FTR markets. Following discussions with MISO management, MISO resolved to grant Big Rivers partial relief (i.e., for the overstated congestion on August 9 and 20, 2014). Status of Resolution of Informal Negotiations On 11/03/15, a Stipulated Order Dismissing Arbitration was issued by the Arbitration Panel.

This dispute concerns an erroneous Day-Ahead Market Demand Bid that was submitted and cleared on November 20, 2013 for Operating Day November 21, 2013. 01/24/14 Resolution of the Dispute Following discussions with management officials, MISO confirmed that lost opportunity costs are not compensated by MISO or contemplated in MISO’s Tariff. Following discussions with management officials, it was confirmed MISO’s Markets Settlements Business Practices Manual specifies combined cycle units are settled at an aggregate level. Following discussions with management officials, MISO agreed to pay Minnesota Municipal for start-up costs for the July 17-18, 2013 Operating Days. Following discussions with management officials, MISO agreed to issue a Miscellaneous Adjustment for Operating Day November 21, 2013 based on an analysis of what MISO’s Market Settlements would have calculated with corrected MW values for the impacted Operating Day, and certain adjustments.
