ANSWER OF SOUTHERN REGULATORS IN SUPPORT OF MOTION FOR 
EXTENSION OF TIME 
 
The Mississippi Public Service Commission, the Arkansas Public Service Commission, 
and the Louisiana Public Service Commission (the Southern Regulators) submit this answer1 in 
support of the Public Interest Organizations’ (PIOs)2 motion for an extension of time3 to submit 
comments on the Midcontinent Independent System Operator, Inc.’s (MISO) Zero-Injection 
Generator Interconnection Agreement (ZGIA) proposal in the above captioned docket. The PIOs 
request that the Federal Energy Regulatory Commission (Commission) extend the comment 
deadline in this proceeding by seven days from September 8, 2026, to September 15, 2026. Good 
cause exists for the Commission to grant the PIOs’ request.4  
The ZGIA proposal is part of MISO’s response to a recent Show Cause Order,5 which 
required MISO to either (i) explain why its tariff remains just and reasonable and not unduly 
discriminatory or preferential without provisions addressing, among other things, transmission 
service and co-location arrangements for large load customers or (ii) file amendments to make its 
tariff just and reasonable as applied to large and co-located loads.6 The ZGIA framework is

and exclusively serve large loads. As retail regulators of public utilities, the Southern Regulators 
have a substantial interest in understanding how the ZGIA proposal will impact reliability in MISO 
South and fit into MISO’s holistic Show Cause Order Response. Understanding these complex 
and novel issues requires the additional time requested by the PIOs.  
Therefore, the Southern Regulators support the PIOs’ motion to extend the deadline to 
submit comments on MISO’s ZGIA proposal from September 8, 2026, to September 15, 2026.
