Smart Grid

Build and run the modern grid with industrial-strength, real-time data-centric capabilities

⇠ Back to Energy Systems

Future-Proof the Evolving Power Grid

RTI Connext provides a flexible, open and secure databus that enables new operation models, including two-way exchange of electricity and real-time information for improved delivery from generator to outlet. Used by the world’s leading energy companies, Connext enables intelligent information flow from generation to delivery to power distribution to real-time demand, regardless of device or location.

Connext protects existing and future investments by seamlessly integrating new equipment with legacy equipment and protocols without the need for servers or brokers. Devices connect directly to other devices or applications — dispersed or centrally located — running any type of hardware, software or over any type of network. Connext enables autonomous grid operations for real-time configuration changes and personnel/system updates. It works with legacy solutions as well as the latest technologies, such as blockchain and InfluxData. Built-in security protects and modernizes even the oldest proprietary protocols.

To prepare operators for the growing challenges facing the industry, Connext supplies data for Dispatcher Training Simulator (DTS) and Operator Training Simulator (OTS) systems for realistic simulation of real-world emergency and routine scenarios.

As a leader in smart grid solutions, RTI was awarded funding from the U.S. Department of Energy to advance continuing smart grid research and development, utilizing the DDSTM standard.

Learn how Connext meets today’s requirements while protecting the investments of yesterday and future proofing systems of tomorrow.

Use Cases / Features

Use Case Feature Value

Legacy protocol incorporation

Security, interoperability

By embedding on a device, or going through a gateway, even the oldest protocols are made modern and secure

Microgrid, DER deployment


Modern communications frameworks (i.e. 61850) are well established, but communications (i.e. GOOSE) are lacking. Connext DDS unifies the data

Evolving data models

Extensible types (X-Types)

Maintains interoperability between subsystems and over time, despite differences in the data model

Architecting for the future

Layered databus

Operational, maintenance, APM, Controllable data are layered and shared according to where you want, not what you can have

Heterogeneous or unknown hardware platform

Extensive platform and transport support

Application can be moved between different operating systems and hardware platforms, and use different transports without any code changes

Modular development

Data-centric architecture

Application depends only on the data interface, not on the behavior of other modules


Peer-to-Peer, brokerless, server less

Proven capability to scale from a small PoC to a very large system with 100,000’s of data points

Reusing IP in new projects and production

Robust, future proof architecture

Applications can be migrated to production grade, or new projects, seamlessly
