Provides that: (1) eligible project development costs incurred for a project that is canceled or not completed may be recovered by the eligible utility if found by the IURC to be reasonable, necessary, and prudently incurred; but (2) such costs shall be recovered without a return unless the IURC makes certain additional findings.	us/states/in	Indiana General Assembly	2025	SB 423	Indiana SB 423 (2025)	bill	AGENCIES; Utility Regulatory Commission (IURC) ECONOMIC DEVELOPMENT ENERGY; Nuclear TECHNOLOGY; Generally UTILITIES; Electric UTILITIES; Generally	enacted	Edmond Soliday Eric Koch Spencer Deery Stacey Donato	4	29	3	2025-01-13	2025-05-01	openstates	ocd-bill/18904e45-0661-4d4a-b1b4-d10649ee95ae	https://api.iga.in.gov/2025/bills/sb0423	cfd050dd85844646c74e0f773f6b3f3c33e8ec2cde85497805640114eca368e4	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-in
