This blog is the first in a three-part series on defining a practical path from AMI 1.0 to AMI 2.0. We will begin with understanding why grid modernization has become more complex, then outline the principles of a practical transition. We’ll close by sharing real-world experiences and lessons learned from utilities on their own grid modernization journeys.

Advanced metering infrastructure (AMI) has been a foundational utility technology investment for decades. AMI 1.0 systems remain essential to daily meter reading, billing and customer service operations. 

These systems continue to perform reliably;  however, utilities increasingly need them to support a broader range of grid requirements. Accelerating electrification, distributed energy resources (DERs) and increasingly severe weather events are driving the need for greater visibility, intelligence and action across the grid. These requirements extend beyond what AMI 1.0 was designed to address.

For utilities planning their next phase of modernization, the discussion often comes down to balancing two realities: existing investments continue to provide value, while evolving grid challenges are creating demand for new capabilities. The path forward must account for both.

Why Grid Modernization Has Become More Challenging
Many AMI deployments were originally implemented to support meter-to-cash operations. Now, utilities are looking for better visibility into distribution system conditions, faster access to operational information and new tools to support reliability and resiliency initiatives. 

Utilities are also making modernization decisions in an environment where affordability remains a significant concern. Between budget constraints, regulatory oversight and customer expectations, today’s infrastructure investments are evaluated under a microscope. In addition, many organizations are seeking flexible, interoperable technology strategies that prevent vendor lock-in and can adapt to changing business and operational needs over time.

A Simple AMI Refresh Isn't So Simple
Replacing aging infrastructure is rarely a standalone technology decision. Over time, AMI systems become closely tied to utility operations. Integrations with billing and outage management systems are established and continually refined. Business processes are built around those systems, and utilities develop institutional knowledge related to their operation and maintenance.

Modernization efforts are also occurring as many utilities expand their use of data and analytics. Teams that have historically focused on meter-to-cash are now supporting a broader range of grid and data-driven initiatives across the enterprise. Those changes often require new skills and additional training, along with updates to established workflows. 

Additionally, replacing assets that are still within their expected lifecycle can have financial implications beyond the technology itself. Every investment is closely scrutinized by regulators and must demonstrate measurable value to obtain approval. Regulatory requirements can significantly influence modernization plans, investment decisions and business case development.

Long-term planning considerations add another layer of complexity. Utilities are making decisions that may affect operations for many years, making it important to balance near-term needs with future flexibility while minimizing disruption to established business processes and operational workflows.

A False Choice Between “Delay” and “Replace Everything Now”
Every utility is approaching modernization from a different starting point. Existing AMI investments, regulatory considerations and broader grid modernization priorities all influence how organizations evaluate their options.

Some continue operating existing systems while evaluating the timing and scope of modernization efforts. Others pursue larger replacement programs intended to introduce new capabilities within a shorter timeframe. Both approaches come with tradeoffs, particularly as utilities balance modernization goals with affordability concerns.

As a result, the decision can feel like a false choice: continue relying on systems that still work but were not built for modern grid challenges or pursue a full replacement that will introduce new risk, cost and operational disruption before the existing AMI investment has reached the end of its useful life. 

Many organizations today are exploring ways to add new functionality while continuing to leverage investments already in place.  Utilities do not have to choose between delaying modernization and replacing everything now.  They can preserve infrastructure that continues to deliver value while introducing new capabilities where they are needed most.  This creates a practical path forward that advances modernization  without abandoning what's working.

Introducing a Different Approach: OpenWay Forward
OpenWay Forward—Itron’s supported, phased approach to AMI modernization—was developed with those realities in mind. It’s designed to help utilities build on existing investments while introducing new capabilities over time and maintaining business continuity.

The approach provides a path from AMI 1.0 to AMI 2.0 through the phased adoption of technologies such as UtilityIQ, Gen6 network infrastructure, Distributed Intelligence and Grid Edge Intelligence. Utilities can strategically deploy these solutions over time rather than replacing infrastructure all at once, allowing modernization efforts to progress at a pace that fits their operational and business needs.

Building on What Utilities Already Have
Many AMI 1.0 systems continue to support critical utility operations and remain an important part of the utility technology landscape. 

What is changing is the approach. Modernization isn’t all or nothing, nor does it require starting over. Utilities must determine how the systems and processes they already have can continue creating value while new solutions are introduced to meet evolving business and operational needs. 
OpenWay Forward was designed to support that transition by helping utilities bridge existing AMI investments with the next generation of grid capabilities.

The best path to modernization recognizes what should change, what can stay and how the two can work together.

In the next blog in this series, we’ll look closer at the key principles utilities can use to evaluate what a practical, lower-risk transition from AMI 1.0 to AMI 2.0 should include.
