TRUSense Gateway™

A Data-Centric Approach to AMI that Enables Unified Intelligence

The Convergence of Four Utility Initiatives

The TRUSense Gateway is a multi-purpose device that can be installed in any ANSI meter socket to create a secure communication pathway via a fiber, ethernet or cellular network to devices deployed across the distribution grid and a seamless path to communicate and control devices located behind the meter.

In a larger sense, the TRUSense Gateway is a first-to-market innovation that helps utilities capitalize on the convergence of four major initiatives across the utility industry, including:

Data-centric AMI: Reap the benefits of AMI 2.0 without having to replace existing meters
Grid optimization: Capture and analyze substation-level power-quality data at the meter socket to improve infrastructure performance and target investments.
DER integration: Enable visibility , command and control of behind-the-meter resources such as EV chargers, solar and storage inverters, and smart appliances.
Broadband initiatives: Leverage investments in fiber to connect and backhaul data from existing meters and power optical network terminals that deliver broadband services to the home.

In short, the TRUSense Gateway empowers utilities to accelerate their grid modernization efforts and achieve the benefits of Unified Intelligence in the most flexible, cost-effective and lowest-risk way possible.

Extending the Edge of the Grid to Behind-the-Meter DERs

The TRUSense Gateway extends the edge of the grid to include behind-the-meter assets, creating a secure utility communications path into the premise for advanced data, control, and broadband connectivity.

As an integral part our Tantalus Grid Modernization Platform™, TRUSense Gateway solutions provide utilities with improved visibility, command and control across the entire grid while minimizing the need to rip and replace existing meters.

Benefits of the TRUSense Gateway:

Detects and manages behind-the-meter devices, such as electric vehicle chargers, solar and storage inverters and smart appliances and DERs deployed across the distribution grid
Improves system balancing and restoration efforts
Advanced power quality monitoring with real-time communications to avoid truck-rolls while gaining a granular view of the distribution network
Works in parallel with TRUSync to simplify the acquisition, transport and integration of data from DERs and edge devices
Offers relationships with manufacturers of Smart Inverters, Grid Scale DERs, EVs, Electric Fleets
Allows utilities to leverage existing investments and deploy a data-centric AMI system at their own pace (no forced “rip and replace” of existing meters)
Extends and augments existing AMI and AMR investments, including electric, water and gas
Provides a pivotal component of a proven, cost-effective path to Unified Intelligence, with dozens of utilities having already deployed TRUSense Gateways

Industry-Leading Visibility, Command and Control Behind-the-Meter

As utilities witness the proliferation of DERs installed in residences, such as electric vehicle chargers, solar and storage inverters and smart appliances, being able to access and control these devices is becoming increasingly important. TRUSense Gateway provides an opportunity to build robust demand-side flexibility programs to mitigate imbalances between the supply and demand of electricity, protect assets such as transformers, mitigate the expense of power outages and improve workforce safety.

By leveraging a Wi-Fi access point and HomePlug GreenPHY IP technologies that are embedded on the TRUSense Gateway, utilities gain a secured and dedicated communication path to connect to each device without relying on a consumer’s Wi-Fi network. Having a dedicated communication path to these devices enables utilities to build reliable demand-side programs effectively and accurately in order to reduce both peak demand charges and reduce long-term supply and transmission expenses.

Coupled with TRUSync Grid Data Management, utilities benefit from the true interoperability of data from each of these devices. Once secure IP communication is established through the TRUSense Gateway, DER technologies located behind-the-meter are directly visible and accessible to the utility and can be integrated with an Advanced Distribution Management System (ADMS) or DER Management System (DERMS). Tantalus provides applications to harmonize communications protocols from the DERs (e.g., IEEE 2030.5, SunSpec MODBUS) to protocols used by ADMS or DERMS (e.g., DNP3), to manage the interaction of DERs with disconnect switches for demand-side programs.

Gateway Versions

The TRUSense Gateway is available in three versions to accommodate different communications environments:

TRUSense Fiber Gateway: Connects directly to fiber by use of a Small Form-factor Pluggable (SFP) Optical Network Terminal (ONT)
TRUSense Ethernet Gateway: Supports an outdoor ONT deployment (providing power to the ONT and connecting via an ethernet cable)
TRUSense Cellular Gateway: Leverages an embedded LTE modem for those utilities not deploying fiber to the home (FTTH) to leverage public or private LTE for AMI and/or DER integration

The TRUSense Gateway is more than a communications device—it’s the bridge to a truly data-centric grid.

As part of the Tantalus Grid Modernization Platform™ (TGMP™), TRUSense provides utilities with a proven, secure, and cost-effective foundation for next-generation AMI, DER integration, and Unified Intelligence.

By empowering utilities to modernize at their own pace, TRUSense helps utilities achieve a resilient, reliable, flexible, and sustainable energy future—delivering the most cost-effective, lowest-risk path to grid modernization.
