Key Issues

- —
AES Indiana (IPL) coal retirement cost recovery: IURC adjudication of AES Indiana's request to recover stranded costs and accelerated depreciation associated with Petersburg coal plant retirement, including contested intervenor arguments regarding imprudent investment and over-collection through prior rate cases.

- —
