The MISO region, including all zones in the South, is expected to have ample electricity-generating resources to meet expected demand in the next five years. Results from the Organization of MISO States-MISO Resource Adequacy Survey released in June show an improved outlook compared to last year.
“Zones 8, 9 and 10 all look positive for MISO South from 2018 through 2022,” explains Todd Hillman, vice president and South Region executive for MISO. “Our survey with the Organization of MISO States continues to provide a valuable outlook and greater certainty around where we are headed in terms of resource adequacy.”
In the MISO region, load serving entities, with oversight by the states as applicable by jurisdiction, are responsible for resource adequacy.
Across the broader footprint, the improved outlook through 2022 is due in part to lower demand, the expected availability of plants that were previously thought to be on track for retirement, and an improved survey methodology that counts some planned energy projects as potential resources going forward.
The survey indicates that certain locations within the MISO region may fall below their resource requirements in 2018 and beyond. However, load serving entities in these areas should be able to reliably acquire capacity from outside their zones to meet these needs, a benefit of being part of MISO.
The reserve margin across the MISO region will range from about 16 percent to 22 percent in the 2018-2022 timeframe, sufficiently above the expected Planning Reserve Margin Requirement of 15.8 percent.
“We appreciate continued collaboration with the Organization of MISO States to provide this outlook on supply and demand in the MISO region,” said MISO President and CEO John Bear. “This forward-looking view informs and enables collective actions by states and MISO members to ensure continued resource adequacy.”
The Organization of MISO States and MISO conduct the survey annually to provide insight into the balance of energy supply and demand for future years.
“The OMS-MISO Survey provides a holistic view of available generation resources across the region at a period in time and thus serves as an important tool to aid state and local regulators and load-serving entities in planning for resource adequacy,” explained Angela Weber, president of the Organization of MISO States and commissioner of the Indiana Utility Regulatory Commission.
More detailed survey results will be discussed during the Resource Adequacy Subcommittee meeting July 12.
