NiSource Inc., through subsidiary NiSource Generation Company LLC (GenCo), entered into a battery storage tolling agreement with Atlas Storage 1 LLC, an indirect subsidiary of AGP Capital Holdings Pte. Ltd. (AGP Group). AGP Group will develop, construct, own and operate a stand-alone battery system with 600 MWAC of capacity and 2,400 MWh of storage, interconnected to the Midcontinent Independent System Operator (MISO) transmission system.
GenCo will supply the electricity used to power the project and may direct its dispatch and receive the economic benefits of its available capacity, discharged energy and services. The delivery term is expected to be approximately twenty and a half years, beginning when the first phase reaches commercial operation, expected by December 1, 2027.

The agreement is expected to be accounted for as a finance lease obligation. Its effectiveness is conditioned on AGP Group executing an engineering, procurement and construction contract and an interconnection agreement reasonably satisfactory to AGP Group by January 31, 2027. GenCo also has an exclusive and irrevocable option to purchase the project at specified intervals during and at the end of the delivery term.
