AES Indiana's $71M Rate Order Hangs on One Court Ruling

If you have been following TEG Daily, you know we first covered Andy Zay's removal from the IURC on August 4 and the resulting commission vacancy on August 10. What is new today is the lawsuit (filed August 10 in Marion Superior Court) and the structural deadline underneath it.

Zay's complaint names Governor Braun, new Braun appointee Joshua Bain, Energy Secretary Suzanne Jaworowski, and two state personnel officials as defendants. The "for cause" removal argument matters, but the more consequential allegation is the ex parte claim: Jaworowski allegedly called Zay two days before the June vote to remind him "affordability is a big deal to this Governor," and Braun's office reportedly sought access to non-public IURC investigative materials. If that allegation survives discovery, it does not just reach the AES case, it creates due-process exposure across every pending rate proceeding before the commission, including NIPSCO's $38 million coal plant cost recovery case.

Here is the binary every central Indiana plant leader needs to model before September 5.

Zay reinstated: The $71 million rate order likely holds as originally structured, giving manufacturers in AES Indiana's service territory a stable rate baseline to plan against through the Phase 2 increase scheduled for January 2027.

Bain seated through September 5: A Braun-aligned majority could grant reconsideration, reverse the order, and trigger refunds on Phase 1 charges already collected since July, while eliminating the Phase 2 increase. That sounds like relief, but it also means the regulatory trajectory is unpredictable, and any planning assumption you built around rate certainty through 2030 is invalidated.

The Marion Superior Court's ruling on reinstatement is the single event that determines which scenario plays out. Get someone tracking that docket this week.
