Alphabet’s subsidiary behind a northern Indiana data center has signed a long-term energy supply agreement with NiSource Inc. which is one of the largest gas and electricity utility companies in the US. The agreement also comes decisively in Alphabet Inc.‘s US data center expansion strategy. It is also an important milestone for Google’s parent company as it aligns hyperscale growth with dedicated energy infrastructure, especially with the AI-driven demand that continues to reshape power markets across the US.
Alphabet’s Indiana Data Center Power Supply Deal with NiSource: An Overview
The agreement will see NiSource supply long-term electricity capacity and energy to support the development and operation of a major hyperscale data center campus in northern Indiana.
Key details include:
- Power delivery scheduled to begin in summer 2026
- Supply structured through NiSource’s NIPSCO Generation (GenCo) model
- Model is designed specifically for large-load customers such as hyperscale data centers
The GenCo model aggregates power from a portfolio of generation assets and market purchases. This enables faster deployment of capacity without overburdening existing grid users.
While the exact site location and capacity of the data center remain undisclosed, the scale and structure of the agreement clearly indicates a hyperscale facility. Most likely line in with Alphabet’s US cloud and AI infrastructure rollout.
The Evolving US Data Center Landscape
This agreement also sits at the intersection of two major trends:
1. Hyperscale expansion beyond traditional hubs
Northern Indiana is emerging as a secondary data center market. This mainly because it benefits from:
- Lower land and operating costs compared to primary hubs
- Proximity to Chicago’s connectivity ecosystem
- Access to large-scale power infrastructure
2. Energy-first data center development
Unlike earlier phases of hyperscale expansion, where power followed construction, this project follows a power-led development model, where:
- Energy agreements are secured prior to construction and/or operations start
- Dedicated generation is ring-fenced for hyperscalers
- Utilities act as strategic partners and not just suppliers
NiSource’s approach through its GenCo structure also allows it to serve hyperscalers without passing costs to existing residential customers. This is currently a key regulatory and political concern in the US.
Alphabet’s Indiana Data Center Power Supply Deal with NiSource: Project Cost
While the contract value has not been publicly disclosed, the agreement carries significant financial implications. These include:
- NiSource’s GenCo portfolio is expected to provide 340MW of dedicated capacity, with additional market purchases of up to 175MW
- The broader program is projected to deliver $1.25 billion in savings for existing customers
- A $17 million community fund will support host regions
The deal also triggered a positive market response, with NiSource shares rising following the announcement. Market-wise, it is a reflection of investor confidence in utility-led data center growth.
