Three EAM platforms dominate large utility deployment: IBM Maximo, Infor EAM, and Hexagon EAM. Each has distinct strengths. This guide compares them head to head for utility applications.
Overview
| Platform | Owner | Utility strength |
|---|---|---|
| IBM Maximo | IBM | Deep functionality, broad ecosystem |
| Infor EAM | Infor | ERP integration, mid to large utilities |
| Hexagon EAM (formerly Intergraph) | Hexagon | GIS integration, complex asset network |
IBM Maximo

- Strong for network assets (transmission, distribution).
- Deep utility industry heritage.
- Handles complex linear assets.
Weaknesses
- Less breadth than Maximo for non network assets.
- Smaller ecosystem than Maximo.
- Enterprise pricing.
Cost comparison
| Platform | Approximate range |
|---|---|
| IBM Maximo | USD 500,000 to 5 million first year |
| Infor EAM | USD 300,000 to 3 million first year |
| Hexagon EAM | USD 400,000 to 4 million first year |
Deployment
| Platform | Typical deployment time |
|---|---|
| Maximo | 12 to 24 months |
| Infor EAM | 9 to 18 months |
| Hexagon EAM | 12 to 24 months |
Best fit for utility scenarios
AI and analytics
IBM Maximo with Watson has strong AI marketing but variable real world outcomes. All three platforms offer condition based maintenance capabilities. Analytics depth varies by module.
Mobile capability
All three offer mobile applications. Maximo Anywhere and equivalents. Modern mobile UX varies by version. Historical Maximo mobile has been weaker than modern competitors.
Integration ecosystem
Maximo has the broadest ecosystem. Third party integration partners for SCADA, GIS, ERP, and specialised applications extensive. Infor and Hexagon smaller but sufficient for most utility applications.
Cloud vs on premises
| Platform | Cloud offering |
|---|---|
| Maximo Application Suite (cloud native) | Available |
| Infor EAM CloudSuite | Available |
| Hexagon EAM cloud | Available |
Reference customers
| Platform | Notable utility customers |
|---|---|
| Maximo | Many large utilities globally, Duke, ConEd |
| Infor EAM | North American utilities, transit agencies |
| Hexagon EAM | Water utilities, electric T and D |
