Where each one falls short

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

PowerFactory DIgSILENT

  • No prices are published; the product pages only offer Request a Quotation and Demo Request
  • The commercial licence is sold by node count, in tiers of 100, 250, 500 or unlimited nodes
  • Functions are sold as a configurable package rather than included, so advanced modules are priced separately
  • Support, maintenance and upgrades are included only for the first 12 months of a perpetual licence and then require an annual maintenance contract
  • The number of concurrent users on the Multi-User Edition is limited to the number of licences purchased
  • A floating licence used on a local machine is time limited to a maximum of 30 days
  • Centralised project data on Oracle, SQL Server or PostgreSQL requires the Team Edition; Single-User and Multi-User editions use a local SQLite database
  • Education licences are capped at 50 nodes and forbid commercial use
  • Student licences are capped at 50 nodes, are cloud softkey only and expire 12 months from issue

Wattwatchers EMS

  • Requires hardware installation at each monitoring point, increasing total cost of ownership
  • Built for small to medium portfolios; scaling to large portfolios may present usability challenges
  • Limited to energy monitoring; not a comprehensive building management system
