AES Indiana files to convert Petersburg coal units to natural gas
March 15, 2024
In filing a Certificate of Public Convenience and Necessity (CPCN) this week, AES Indiana sought the right to repower Petersburg Units 3 and 4 from coal to natural gas.
This would make the utility the latest to push away from coal, as the once dominant energy source continues a rapid decline in American use. Petersburg are the remaining coal units at AES Indiana’s disposal, and their redesignation aligns with the company’s 2022 Integrated Resource Plan that called for the most reliable portfolio at the least cost. That same plan called for the addition of approximately 1,300 MW of wind, solar and battery energy storage through competitive bid projects elsewhere.
