The short version

  • Each has a real cost: ETAP no pricing is published, and reaching a figure requires completing a multi step quote form; HOMER Energy now owned by UL Solutions rather than being independent
  • They diverge on capability: ETAP covers Load flow analysis, HOMER Energy covers Microgrid optimization.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

ETAP

  • No pricing is published, and reaching a figure requires completing a multi step quote form
  • Subscription durations offered are 3 years and 5 years, so there is no short commitment option
  • Licences are banded by user count rather than sold individually, in brackets of 1, 5 to 15, 15 to 25, 25 to 50 and over 50
  • National and international network licences are priced separately

HOMER Energy

  • Now owned by UL Solutions rather than being independent
  • Split into three separate products, HOMER Pro for off-grid and microgrids, HOMER Grid for bill optimisation and HOMER Front for utility-scale, so the right one depends on project type
  • Pricing is not shown on the product pages
