The Organization of MISO States and MISO Release Results of Annual Resource Adequacy Survey

The MISO region will have ample electricity-generating resources to meet expected demand while also maintaining an adequate supply of reserves for the next five years, according to the latest annual resource adequacy survey. The results show an improved resource adequacy outlook compared to last year.

The enhanced outlook is due in part to lower demand in the region, 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.

"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 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.

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 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.

In the MISO region, load serving entities, with oversight by the states as applicable by jurisdiction, are responsible for resource adequacy.
