The short version

  • Each has a real cost: HOMER Energy now owned by UL Solutions rather than being independent; Landis+Gyr Gridstream the platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • They diverge on capability: HOMER Energy covers Microgrid optimization, Landis+Gyr Gridstream covers Advanced metering infrastructure.
  • 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.

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

Landis+Gyr Gridstream

  • The platform depends on Landis+Gyr metering hardware, including electric, gas and water meters plus communication network devices, rather than being sold as software alone
  • No price, licensing model or subscription term is published on the solutions pages; the site offers only a contact form and a distributor finder
  • Deployment, integration and ongoing optimisation are sold as separate Lifecycle Services rather than included
