AES Indiana announced the commissioning of the Petersburg Energy Center in Pike County, Indiana, a new energy infrastructure project integrating 250 MW of solar generation and 180 MWh of battery storage. The facility enhances regional power supply security, stabilizes the power supply during peak demand periods, adds operational flexibility to the system, and aligns with the company’s energy transition strategy.
Energy infrastructure in Indiana: new solar and energy storage center
AES Indiana, a subsidiary of AES Corporation, confirmed that the Petersburg Energy Center is now in service at the site of the historic Petersburg generating station, which has supplied electricity to central Indiana for decades. The project incorporates renewable generation assets and energy storage as part of the modernization of the region’s power infrastructure.
The company stated that the facility is part of its generation diversification strategy, aimed at maintaining grid reliability in the context of growing demand, increased energy market volatility, and the gradual retirement of conventional generation units.
Solar capacity and energy storage for supply security
The energy complex features 250 MW of solar capacity, distributed across more than 515,000 photovoltaic panels, as well as 180 MWh of battery energy storage, designed to support peak demand management and enhance regional grid stability.
From an operational standpoint, the combination of solar generation with energy storage improves system responsiveness to load variations, reduces exposure to electricity market volatility, and strengthens supply security during periods of high seasonal demand. This type of configuration has become a key component of emerging energy infrastructure models across the United States.
Capacity planning and energy transition in the power grid
The Petersburg Energy Center was identified as a strategic project within AES Indiana’s 2022 Integrated Resource Plan (IRP), particularly to replace capacity retired from Petersburg Units 1 and 2 and to support long-term capacity planning in compliance with the Midcontinent Independent System Operator’s (MISO) seasonal capacity requirements.
The commissioning of this asset supports the regional power system’s transition toward a more diversified energy mix, in which renewable sources and energy storage play an increasingly important role in maintaining supply reliability without compromising grid stability.
Regional impact and beneficiary sectors
Beyond its technical contribution to the power system, the project has a direct impact on the local economy of Pike County, a community historically linked to energy generation. AES Indiana indicated that the investment associated with the Petersburg Energy Center is part of a broader program to modernize energy assets across the region.
From a sectoral perspective, the main beneficiaries include industrial and commercial users, who rely on a stable power supply for their operations, as well as transmission and distribution system operators, who gain access to new flexible resources for grid management. The project also strengthens the critical infrastructure base supporting industrial development and energy security in central Indiana.
