TROLIE

This webinar recording introduces potential users in the energy industry to the communications specification defined by TROLIE, an LF Energy project aiming to establish an open conformance standard and cultivate a software ecosystem to accelerate the implementation of reliable, secure, and interoperable systems for the exchange of transmission facility ratings and related information. With FERC Order 881 being implemented next year in the United States, most organizations involved in the operation of the transmission system in North America now need to exchange ratings and related information in an automated, frequent manner. This project will help accelerate their implementation and simplify interoperability.

This webinar provides a technical introduction as well as "how to" content from the perspective of TROLIE's primary users - reliability coordinators and transmission owners.

The webinar was presented by Christopher Atkins of MISO and Tory McKeag of GE Vernova.

The TROLIE Working Group was started to address the interoperability challenges brought on by FERC Order 881. The TROLIE 1.0 project scope addresses the key use cases for the exchange of transmission ratings and limits necessary to ensure compliance and reliable operations. In this webinar, the TROLIE maintainers will explore these use cases and highlight how the TROLIE OpenAPI specification addresses them. Attendees will gain insights into the concepts that the TROLIE project identified when articulating solutions to the 881 use cases, as well as how to make effective use of the project documentation and the specification itself. The presentation will focus on ensuring the audience is prepared to implement their respective interoperability use cases. Accordingly, this will be a fast-paced, in-depth tour of all that the project has produced as it nears completion.

TROLIE - Establishing an Open Conformance Standard for the Exchange of Transmission Facility Ratings - Minh Dupuis, GE Vernova

With FERC Order 881, North American Transmission Owners, Transmission Operators, Transmission Providers, and Reliability Coordinators must establish a means to exchange ratings information based on current and forecasted ambient conditions. There is no standards body with a mandate to define a technical specification for that exchange and no vendor consortium that is working toward a specification. TROLIE started as a MISO and GE Vernova collaboration and is now an LF Energy project. Most organizations involved in the operation of the transmission system in North America now need to exchange ratings and related information in an automated, frequent manner. This project helps accelerate their implementation and simplify interoperability. The project’s specific aims are: -Define an API specification for the exchange of ratings and ratings-related information to support organizations working to comply with FERC Order 881. -A conformance program to provide vendors a means to demonstrate their compatibility with the above specification and signal their commitment to maintaining compatibility. -An open commons for the development of clients of the API specification.

This is a recording of a presentation at the Open Sustainability Policy Summit in Washington, DC. It was presented by Christopher Atkins of MISO and Tory McKeag of GE Vernova.

Abstract: Policymakers strive to ensure positive impacts, but implementation hurdles often blunt or delay those effects. When intricate technological coordination is required, navigating these hurdles among myriad stakeholders can be a painstaking and time-consuming process.

This talk presents TROLIE, an open-source initiative addressing this challenge in the context of FERC Order 881. The Order mandates the use of ambient-adjusted ratings, requiring the communication of hourly forecasted and real-time ratings and limits data between entities who ensure the reliable and economic operation of the electric power grid. Historically, implementing such mandates entails individual stakeholders developing proprietary solutions, leading to inefficiencies and inconsistencies.

TROLIE, on the other hand, fosters interoperability between stakeholders by providing a community-driven, open-source specification for the data exchange. This specification serves as a common language, streamlining communication and interoperability between diverse systems. Stakeholders may contribute directly to its development, ensuring it meets their needs and fosters innovation.

This talk will explore several benefits of TROLIE's open-source approach from the perspective of accelerating the implementation of Order 881, including:
• Contributor Accessibility: Transparency, a simple participation model, and IP clarity promote engagement
• Software Commons: Practical examples supported by a community of implementers engenders predictability and reliability in disparate implementations
• Simplified Governance: Ensures low ceremony, a clear path to adoption, and sustainability

The talk concludes by discussing the broader applicability of TROLIE's open source approach. By demonstrating the power of open source collaboration in accelerating policy implementation, it serves as a model for tackling similar challenges, paving the way for faster and more impactful policy realization.

The Open Sustainability Policy Summit was hosted by the Johns Hopkins University Whiting School of Engineering, May 2-3, 2024.

LF Energy TROLIE is establishing an open conformance standard and cultivating a software ecosystem to accelerate the implementation of reliable, secure, and interoperable systems for the exchange of transmission facility ratings and related information.

This session is an open forum for anyone implementing ratings integrations using the TROLIE specification. The goal of this workshop will be about asking deep questions of specific implementations, and helping to work out corner cases with a community of experts.

The session will include experts from MISO, SPP, ISO New England and GE Vernova.

Keynote: Commercial by Design: Turning Open Source into Grid transformation with TROLIE, LEP, and GridOS® - Minh Dupuis, Global Product Lead MMS, GE Vernova

As the electric grid becomes more complex, fragmented, and decentralized, software must evolve just as radically. In this keynote, Minh Dupuis, Global Product Leader for Market Management Systems at GE Vernova, shares how open-source collaboration is powering that evolution — and turning into real commercial success.

Minh will walk through the journey of developing LEP (Limit Exchange Portal), a licensed product built on top of TROLIE, an open-source API hosted by LF Energy. He’ll share how GE Vernova strategically decides what to open and what to monetize, and how this model accelerates adoption, lowers friction with competitors, and increases customer trust.

This approach is part of a broader transformation: GridOS, GE Vernova’s next-generation grid software platform, is designed from the ground up to leverage open-source software and modular, grid-specific innovation. For anyone navigating the intersection of energy, software, and open ecosystems — this keynote offers real-world strategy and lessons.
