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.

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 will help accelerate their implementation and simplify interoperability.

The project’s specific aims are:

  • Define API specification for the exchange of ratings and ratings-related information to support organizations working to comply with FERC Order 881.
  • A conformance program that emulates that Zowe Conformance Program or the Certified Kubernetes Conformance Program insofar as they give vendors a means to demonstrate their conformance to the above specification and signal their commitment to maintaining their conformance over time.
  • An open commons for the development of clients of the API specification.

We are committed establishing a vendor-neutral specification and building an inclusive community.

TROLIE - Establishing an Open Conformance Standard for the Exchange of Transmission F... Minh Dupuis

September 22, 2024 10:00 pm

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.
