Nothing recorded yet. See the Azelio Energy Storage review.

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
