Docket No. ER27-25-000


COMMENTS ON BEHALF OF THE SOUTHERN REGULATORS IN SUPPORT OF MISO APPLICATION

Pursuant to Rule 212 of the Federal Energy Regulatory Commission’s (“Commission” or “FERC”) Rules of Practice and Procedure[fn:1], the Arkansas Public Service Commission (“APSC”) respectfully submits these comments regarding the Midcontinent Independent System Operator, Inc.’s (“MISO”) proposed revisions to its Open Access Transmission, Energy and Operating Reserve Markets Tariff (“Tariff” or “MISO’s Tariff”) to establish the Large Load Addition Resource Study (“LARS”).  
The APSC supports MISO’s filing to establish the LARS process, and agrees with the comments made by the Mississippi Public Service Commission and the Louisiana Public Service Commission.  LARS should be accepted by the Commission because it is just and reasonable.  Further, AR agrees that LARS is a reasonable response to and aligns with the requirements of the Commission’s Show Cause Order.[fn:2] 
Therefore, the APSC respectfully request that the Commission accept MISO’s LARS filing.	


Respectfully submitted,

[fn:2] See Show Cause Order at P 113 (noting that the Commission preliminarily found that MISO’s existing Tariff “may be unjust and unreasonable because it does not provide generator interconnection study procedures and services that account for the operational dynamics of serving electrically proximate large loads.”).
