  • They diverge on capability: EnergyCAP covers Utility bill management, Stem Athena covers AI optimization.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

EnergyCAP

  • Priced per meter per year, so cost scales with how many utility connection points exist rather than with users or sites
  • No figure is published at any level, and every package is quoted by sales
  • Emissions, interval data, bill capture and bill pay are separately priced add ons rather than part of the core platform

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
