Tamazari | Utility ERP Modernization
Connect the Business Systems Behind Reliable Utility Operations.
Enterprise Resource Planning (ERP) touches nearly every part of the utility. When processes and systems do not work together, employees fill the gaps with spreadsheets, duplicate data entry and manual workarounds. Costs become harder to track, decisions slow down and confidence in the information begins to erode.
​
Tamazari helps electric, gas and water utilities turn ERP modernization into better business outcomes. We align processes, data and systems around how teams actually work, then lead the effort from strategy and requirements through migration, integration, testing, training and cutover. The result is better visibility, more consistent execution and a stronger foundation for managing projects.
Case Study: Inside a $40M+ Utility ERP Transformation
A major Pacific Northwest utility needed to modernize a 20-year-old SAP ECC financial system, implement SAP BPC and update integrations with PowerPlan and Trintech—all while keeping the business running and meeting FERC reporting requirements. Tamazari provided project leadership for a 150+ person, multi-vendor team, coordinating governance, requirements, testing, change management and a tightly sequenced cutover.
​
Results included:
-
Both program phases delivered on schedule and within the $40M+ budget
-
SAP BPC launched for more than 500 users with strong adoption
-
FERC reporting capabilities enhanced, with PowerPlan and Trintech integrations modernized.
Utility ERP Modernization Services
We help utilities move from disconnected processes and unreliable data to a coordinated ERP environment built around operational priorities.
ERP Strategy and Modernization Roadmap
Define the business outcomes, implementation priorities and practical sequence for modernization. We help leaders align technology decisions with operational needs, regulatory responsibilities and long-term organizational goals.
Business Process and Requirements Definition
Document how work happens today, identify where processes break down and define future-state requirements. We bring finance, procurement, projects, operations, IT and other stakeholders together around a shared direction.
Data Readiness and Migration
Assess source data, ownership, quality, duplication and dependencies before migration. We help utilities prepare, map, cleanse, validate and govern the information the new environment will depend on.
Utility Systems
Integration
Connect ERP information with the systems used to manage assets, customers, projects, documents and field work. We help define reliable data exchanges, ownership boundaries and integration requirements across the utility environment.
Testing, Cutover and Operational Readiness
Develop realistic test scenarios, coordinate user acceptance testing and prepare teams for deployment. We help utilities identify problems before launch and manage cutover without losing sight of ongoing operations.
A Practical Path from ERP Strategy to Operational Readiness
We move each engagement through four clear stages designed to reduce uncertainty and keep business and operational priorities aligned.
​
1. Assess the Environment
Evaluate existing systems, processes, data, integrations, risks and modernization priorities.
​
2. Define the Future State
Establish requirements, process ownership, system responsibilities, governance and measures of success.
​
3. Prepare the Data and Integrations
Clean and map priority data, build connections and prepare the broader technology environment for deployment.
​
4. Test, Deploy and Enable
Validate end-to-end processes, coordinate cutover, train users and transition the program into sustainable operations.
Utility ERP Modernization FAQs
What is a utility ERP system?
A utility ERP system manages core business functions such as finance, procurement, supply chain, projects, workforce information and enterprise reporting. It often connects with operational platforms that manage assets, customers, documents and field work.​
​
How is ERP different from enterprise asset management?
ERP manages enterprise business and financial processes. Enterprise asset management focuses on asset condition, maintenance and work execution. The systems serve different purposes but should share consistent identifiers, organizational structures and cost information.​​
​
Which systems commonly integrate with a utility ERP platform?
Common connections include enterprise asset management, GIS, CIS and billing, document management, project management, workforce management, inventory and field-service applications. The appropriate integration model depends on which system owns each type of information.​
​
What should a utility address before beginning an ERP implementation?
Start with clear business outcomes, documented processes, defined data ownership and an accurate understanding of existing integrations. Moving directly into configuration without this foundation can reproduce old problems in a new platform.​
​
How can utilities reduce ERP cutover risk?
Use realistic end-to-end testing, validate migrated data, confirm integrations and permissions, prepare contingency plans and involve employees who understand day-to-day operations. Cutover planning should account for both technical deployment and continued business operations.​
​
Why is change management important during ERP modernization?
ERP modernization changes how employees complete everyday work. Early engagement, clear role definitions, practical training and accessible support help employees understand what is changing and use the new processes consistently.​​​
