Analysis · NI · Energy & Transportation
NiSource's GenCo subsidiary locked in a 20.5-year tolling agreement with AGP Group's Atlas Storage 1 LLC for a 600 MWAC / 2,400 MWh battery storage system on the MISO grid. Under the deal, GenCo supplies the power and controls dispatch, capturing the project's capacity, energy, ancillary and environmental-attribute revenues, in exchange for roughly $2.2 billion of fixed-rate storage payments over the term. Because the agreement is expected to be booked as a finance lease obligation, it adds long-term debt-like commitments to the balance sheet even though it is not a share issuance. The project is not yet built: effectiveness hinges on AGP securing an EPC contract and an interconnection agreement by January 31, 2027, with commercial operation of the first phase targeted by December 1, 2027. GenCo also holds an exclusive option to buy the project outright, which would convert the lease into owned generation. This is a meaningful expansion of NiSource's data-center-adjacent generation strategy, but the ~$2.2 billion is spread over two decades and the project carries construction and counterparty execution risk before any capacity comes online.
