On March 4, 2026, Itron, Inc. and Tantalus Systems announced that Itron will extend its Encoder Receiver Transmitter (ERT) license agreement with Tantalus. The extension gives Tantalus the exclusive right to read and deliver the complete ERT messaging structure, allowing utilities to continue using their existing ERT devices while migrating to Tantalus’ data‑centric Advanced Metering Infrastructure (AMI) platform.
The extended license covers a broad range of Itron ERT devices, including the 60, 100, R300, R400, and 500 Series electric, water and gas meters, as well as Bridge Meters and Intelis gas meters. The partnership between the two companies dates back to at least 2011, and the new agreement builds on more than a decade of joint development and deployment of grid‑modernization solutions.
For Tantalus, the extension solidifies its unique market position as the sole AMI provider with a license to interpret the full ERT message set. The agreement enables utilities to preserve the value of their legacy ERT infrastructure while gradually adopting Tantalus’ platform, reducing capital risk and accelerating the transition to a data‑centric grid. The AMI market is projected to grow from $30.33 billion in 2024 to $74.42 billion by 2035, underscoring the strategic importance of this partnership.
Itron’s continued partnership with Tantalus also reflects the company’s broader focus on grid edge intelligence and software‑first solutions. Itron’s Q1 2024 earnings, which saw revenue rise 22% to $603 million and non‑GAAP EPS reach $1.24, demonstrate the financial strength that underpins its ability to support long‑term collaborations. The extended license agreement positions both companies to capture growing demand for modernized metering infrastructure.
Overall, the license extension strengthens the competitive landscape for AMI providers and offers utilities a clear path to upgrade their metering systems without abandoning existing investments. The agreement is expected to drive further adoption of Tantalus’ platform and reinforce Itron’s role as a key enabler of grid modernization.
