New MISO Attributes Roadmap Focuses on Future Grid Reliability Needs

MISO recently (Dec 15) published its Attributes Roadmap report which explores three key electric system attributes required to ensure grid reliability and presents recommended solutions to inform ongoing stakeholder collaboration.  The report presents insights and solutions to the three system attributes where near-term risk is most acute - system adequacy, flexibility, and system stability. 

“We share an obligation to ensure the reliable delivery of electricity to the 45 million people living in our region,” said Todd Ramey, MISO’s Senior Vice President of Markets and Digital Strategy. “The grid requires sufficient amounts of key reliability attributes to meet that obligation every hour of every day.” 

The electric power industry is simultaneously experiencing a shift in the generation resource mix, increased impacts from severe weather, and increasing demand for electricity. The report outlines the following system attributes needed to maintain high levels of electric system reliability: 

• System adequacy: the ability to meet electric load requirements in all operating conditions
  
• Flexibility: the extent to which a power system can modify electric production or consumption in response to changing system conditions
  
• System stability: the ability to maintain voltage stability in all operating conditions

In many instances, new resources do not have the same characteristics as the resources they are replacing. These transformational changes require MISO and its members to study, measure, incentivize, and implement changes to ensure sufficient system attributes to maintain high levels of electric system reliability. 

MISO’s Attributes Roadmap provides insights and recommendations to further ongoing conversations with stakeholders and to advance the development and integration of necessary market reforms and requirements. Near-term work focuses on:

• Further modernization of the resource adequacy construct
  
• Focusing market signals on emerging flexibility needs
  
• Enabling the benefits of emerging resources
  
• Requiring capabilities needed to strengthen the grid

“The analyses that shaped the Attributes Roadmap affirm MISO’s ongoing initiatives and point toward areas to expedite and expand,” noted Jordan Bakke, Director of Strategic Initiatives and Assessments. “MISO looks forward to working with its stakeholders on this proactive and urgent effort to ensure the system is prepared for the future.” 

The report also highlights the continued Response to the Reliability Imperative – the shared responsibility that MISO, its members, and stakeholders have to address the complex challenges facing the bulk electric system. More information about MISO’s System Reliability Attributes work can be found on MISO’s Dashboard for “Identification of Sufficient Reliability Attributes RASC – 2022-1” and in the MISO Stakeholder Resource Adequacy Subcommittee meetings.
