The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Stem Athena.
- Stem's site names the product PowerTrack Optimizer, formerly Athena, so the Athena name is retired
- No price, subscription fee or contract term is published anywhere on the site
- The optimizer is one component of the wider PowerTrack suite alongside separate EMS, SCADA, Power Plant Controller and Logger products rather than a standalone licence
- Design, procurement, commissioning and operation are sold as managed services separate from the software
