How Constellation is building a governed data foundation on Databricks

By · Published by Everything Blog

In short

Constellation is deploying an enterprise foundation on Databricks to bridge disconnected data stacks, including metrics across roughly 2.5 million retail customer accounts. The deployment became critical after absorbing extensive infrastructure from its 2026 integration of Calpine, which brought 79 power plants across 22 states into its corporate orbit. Rather than executing a total architectural overhaul, leadership selected the platform to secure governed artificial intelligence access while supporting engineering tasks. The new infrastructure now assists outage planners, commercial sales pipelines, and technical staff through shared data definitions.

How unifying data governance and semantics prepares enterprise data for AI scaling.

by Renee Voves and Herman Lombard

Constellation operates the largest nuclear fleet in the United States. For them, one of the hardest parts of preparing for AI wasn’t choosing models, it was agreeing on what the data means. Constellation’s team is building a governed Enterprise Data Platform (EDP) on Databricks to make data consistent and usable across the business, and its approach offers a practical roadmap for other enterprises.

Constellation is the nation's largest producer of clean and reliable energy, with generating capacity equivalent to the needs of 27 million homes and approximately 2.5 million retail customer accounts. That breadth of operations and customer relationships is why shared definitions and governance matter to their data work.

Constellation collects data from asset management, supply chain, commercial and trading systems, and operations across the fleet. These are feeding everything from near-real-time market models to nuclear telemetry. In a business where safety and reliability come first, getting definitions and governance right matters. That risk profile drives every architectural choice that follows.
