Constellation is building its Enterprise Data Platform on [Databricks](/startups/databricks) for 2.5 million retail accounts.

Before the move, teams ran strong domain systems with no shared meaning, as detailed in the [Databricks breakdown](https://www.databricks.com/blog/how-constellation-building-governed-data-foundation-databricks) of the project. Retail counted billing meters, wholesale counted counterparties and CRM counted accounts. The 2026 Calpine acquisition then added 79 plants across 22 states and 27 GW of capacity, per [Databricks](https://www.startuphub.ai/startups/databricks), with its own warehouses and definitions.

Constellation picked Databricks in weeks because it could interoperate without rip-and-replace, the company said. Unity Catalog supplies lineage and fine-grained access, while Data Vault is used selectively only for critical, reusable entities. Not every dataset is vaulted.

Three pilots now run on that base. A Genie assistant surfaces approved nuclear engineering information. Outage teams pull scheduling and asset health data together for refueling work. Sales teams get prioritized opportunities and next actions.

Metric views are Unity Catalog securable objects governed with standard privileges in Catalog Explorer or SQL, according to Microsoft Learn documentation. That matters because Constellation still has to decide who owns each definition, a push that follows [Databricks gives agents a shared truth layer](/ai-news/artificial-intelligence/2026/databricks-gives-agents-a-shared-truth-layer).

Constellation is now exploring Genie Ontology and Unity Catalog Pages to manage business definitions centrally.
