The short version
- Each has a real cost: Stem Athena stem's site names the product PowerTrack Optimizer, formerly Athena, so the Athena name is retired; Enel X DER Optimization sold through Enel North America rather than under the Enel X name in this market, and enelx.com redirects there
- They diverge on capability: Stem Athena covers AI optimization, Enel X DER Optimization covers DER aggregation.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Enel X DER Optimization
- Sold through Enel North America rather than under the Enel X name in this market, and enelx.com redirects there
- Aimed at commercial and industrial sites and utilities rather than smaller energy users
