TANTALUS EXTENDS ERT LICENSE AGREEMENT WITH ITRON

Tantalus Systems Holding Inc. has extended its licence agreement with Itron Inc. to support full encoder receiver transmitter (ERT) compatibility across the TruConnect AMI platform, part of the Tantalus grid modernization platform (TGMP).

With the extension of the licence agreement with Itron, Tantalus will continue to have the right to read Itron communications technologies used in early automated meter reading (AMR) systems and legacy AMI (advanced metering infrastructure) deployments, including Advanced SCM+ messaging and enhanced fixed-network functionality such as network interval messaging (NIM). Being able to deliver these messages enables utilities to transition from basic mobile meter reading to Tantalus's modern, data-centric TruConnect AMI platform while extending the life of their existing ERT investments.

With more than 80 million ERT devices deployed across electric, water and gas utilities over the past three decades, ERT technology represents one of the most widely adopted metering architectures in North America. For many public power utilities and electric co-operatives, these devices remain foundational for daily operations. However, as expectations for grid visibility, data granularity and operational intelligence continue to increase, utilities face mounting pressure to modernize without stranding capital-intensive infrastructure investments.

The extended licence agreement directly addresses this industry challenge. Through this agreement, Tantalus is the only solution provider expressly licensed to read and deliver the complete ERT messaging structure across a purpose-built AMI platform engineered to support advanced two-way data logging capabilities. Accessing the full functionality of their ERT end points through TruConnect AMI, as permitted under the licence agreement, allows utilities to maintain Itron warranties and preserve long-term asset value.

The inclusion of the NIM messages allows utilities to receive hourly aligned interval readings and tamper notifications from Itron 100 series-enabled water and gas meters across a fixed network. Using Tantalus's TruScan solution, these readings can be collected automatically rather than relying on periodic drive-by or mobile data collection. This shift from mobile to fixed-network data acquisition enhances system visibility, strengthens operational awareness, and enables more consistent access to interval data for billing, demand calculations and time-of-use programs.

Advanced SCM+ messaging further expands access to advanced features across Itron water, gas and electric meters, positioning utilities to leverage enhanced consumption analysis, customer presentment, and distribution optimization capabilities such as loss and leak detection. Tantalus's full integration with Itron's field collection system (FCS) enables seamless import of ERT reads from both mobile and fixed networks into utility billing systems, dramatically reducing integration risk and lowering deployment costs.

This capability is underpinned by Tantalus's advanced technology stack, including proprietary communications silicon, firmware and protocol-processing technologies designed specifically to support the scale, timing and message complexity of ERT-based fixed-network deployments. These platform investments enable reliable, high-performance decoding and delivery of the complete ERT message, forming the unique technical foundation that makes full compatibility possible.

"Extending this licence agreement reflects the shared commitment between Tantalus and Itron to support utilities' evolving needs for interoperability, efficiency and financial flexibility," said Peter Londa, president and chief executive officer of Tantalus. "Across North America, utilities are navigating how to modernize aging infrastructure while managing cost constraints and changing expectations from customers, state officials and regulators. By accessing the complete ERT message across Tantalus's TruConnect AMI offering, we are helping utilities unlock greater operational intelligence at lower risk and lower overall cost with a data-centric approach to AMI."

The licensed technology supports a broad range of Itron devices, including 60, 100, R300, R400 and 500 series electric, water and gas ERTs, bridge meters and Intelis gas meters. By combining this licensed compatibility with the TruConnect industrial IoT (Internet of Things) smart grid network as well as Tantalus's purpose-built end point communications and protocol-processing technologies, Tantalus provides utilities with a secure, scalable platform that supports two-way communications and advanced grid operations within a modern, data-focused architecture.

As utilities across the industry increasingly prioritize data-driven decision making and grid resilience, the ability to integrate legacy metering assets into a scalable AMI platform has become a critical component of modernization strategy. The extended agreement between Tantalus and Itron reinforces a pragmatic, capital-efficient pathway forward that aligns interoperability, operational performance and financial stewardship in support of long-term grid transformation.
