For many utilities, the transition to Advanced Metering Infrastructure, or AMI, represents more than an operational upgrade, it's a fundamental shift in how meter data flows through your organization. The promise is compelling: eliminate manual meter reads, improve accuracy, and unlock granular consumption data that drives better decision-making.
With so many different technologies to choose from, it can be difficult to select the right type of system to best maximize AMI’s many benefits for your utility. Neptune is one of the only companies that provides multiple data collection technologies, in addition to guidance towards selecting the right system and transmission tools appropriate for your unique goals.
Finding the Best Fit for You
Any great system design starts with the utility’s specific goals and works backwards to the best solution to meet them. Here’s where many utilities stumble: they approach AMI as a technology purchase, rather than a system design challenge. Without starting at the problem to solve, the result is predictable: over-engineered solutions that waste capital, or under-designed networks that fail to deliver the promised ROI.
When evaluating AMI options, a one-size-fits-all pitch sounds appealing. But this simplicity comes at a very real cost, especially in service areas with unique challenges like meters in basements, diverse geographic terrain, expanding population growth, or a mix of legacy and modern infrastructure already in place.
Neptune takes a different approach: we recommend the technology that makes sense for each part of your network. Fixed-network gateways where coverage and density support it. Cellular endpoints where terrain or isolation demand it. Legacy infrastructure where it's still performing well. The question isn't which technology is "best"—it's which combination optimizes performance and cost across your specific service territory.
That's where total cost of ownership (TCO) analysis becomes our guide. A true TCO model accounts for equipment, infrastructure, subscriptions, and maintenance over your system's 10- to 20-year lifespan—revealing whether you're making decisions based on upfront simplicity or long-term value. It's how we apply Neptune's multi-technology flexibility strategically, ensuring each technology choice actually delivers ROI.
In the Real World
Let’s take a look at how this process works with an example.
Neptune worked with a utility with more than 50,000 meters, some in basements, where signal penetration becomes complex. They had a fixed network AMI system with gateways covering just over three quarters of their endpoints. They also identified seven sites available to potentially add new gateways to provide coverage to the remaining endpoints that did not have coverage. The utility needed to understand not just whether or not to use those seven gateway sites, but also how to balance technology choices, infrastructure investment, and customer experience.
Their objective in collaborating with Neptune was to capture the data from all their endpoints and determine the optimal number of additional sites required to achieve this goal. They also needed to evaluate whether to upgrade existing endpoints to newer models or try to maximize the use of their current equipment.
After closer inspection, it was determined that about 15,000 of their endpoints were older than 10 years. They initially considered a solution they saw as straightforward: deploy an all-cellular solution and eliminate the complexity entirely. However, when Neptune stepped in, we started with their goal of 100 percent coverage and, using our proprietary network analysis, we identified a different path. Our assessment accounted for the basement meter challenge, existing infrastructure value, and the specific coverage characteristics of each potential gateway location.
The recommended design:
- Deploy all seven available gateway sites (each location proved cost-effective)
- Upgrade 12,000 of the legacy endpoints to newer R900 technology
- Maintain 3,000 legacy endpoints that were performing adequately
- Deploy just a few hundred cellular endpoints selectively to fill genuine coverage gaps that gateway signals couldn't reach reliably
The result? An estimated $3 million in savings compared to the all-cellular alternative over the system's expected life. More importantly, the utility preserved the value of existing infrastructure that was working, while strategically upgrading only where it made economic and operational sense.
A Partner to Count On
The core difference between a vendor and a true infrastructure partner is one who will take the time to understand your goals and not force unnecessary upgrades and equipment on you, especially if you already have infrastructure that is working. At Neptune, we want to help you let it become a part of your larger system as your AMI migration evolves at your own pace.
