## Voltformer analysis

The release confirms a completed storage asset in operation. Revera owns and operates it; Wärtsilä’s separate JV business model should not be confused with project ownership.

## Considerations for project teams

Commissioning evidence, staged grid-operator acceptance tests and service-agreement performance measures shape the commercial value of a storage project.

When reading contract scope, verify the contracting party, package boundaries, site and grid interfaces, permitting duties, commissioning evidence and operator handover separately.
