CARMEL, Ind. — Results from the latest OMS-MISO survey project the MISO region will have adequate resources for 2019, while continued action will be needed to ensure resource adequacy in the extended outlook. MISO briefed stakeholders on the survey results Friday.
The OMS-MISO survey provides a forward-looking view that informs MISO and stakeholders of the potential future resource landscape and helps inform collaborative action by states and MISO members to ensure continued resource adequacy. This year’s survey projects MISO will have from 0.6 gigawatts to 6.6 gigawatts of generation resources beyond the regional requirement in 2019. The reserve margin is expected to range from 17.6 percent to 22.4 percent next year.
“The OMS-MISO Survey provides a holistic view of available generation resources across the region at this moment in time,” said Ted Thomas, president of the Organization of MISO States and chairman of the Arkansas Public Service Commission. "The survey serves as an important tool to inform state and local regulators and load-serving entities in their planning for resource adequacy.”
Like previous years, the demand forecast continues to indicate slowing growth. The 2019 summer peak forecast decreased 1.5 gigawatts from the 2017 survey. In the five-year outlook, the regional growth rate decreased from 0.5 percent last year to 0.3 percent.
On the supply side, the survey indicates that a decrease in resource commitments beyond 2019 could lead to greater resource adequacy risk. In most of the MISO region, load serving entities, with oversight by the applicable state or local jurisdiction, are responsible for resource adequacy.
“While we continue to see decreasing demand in the MISO footprint, the story continues to be the evolving generation portfolio,” said John Bear, MISO chief executive officer. “As the MISO footprint continues to transform, we must learn to adapt in areas such as our transmission planning studies, market-based solutions that focus on speed and flexibility, and enhancing coordination with our neighboring seams partners.”
MISO is committed to continuing to support state resource adequacy actions that will help ensure sufficient electric resources are available to meet future power demand.
“We appreciate all of the work done by our Load serving entities, along with state commissions and their staffs,” explained Laura Rauch, MISO director of Resource Adequacy Coordination. “Our load serving entities have not only demonstrated they have sufficient resources to meet load and required reserves, but also that being part of MISO allows load-serving entities to acquire needed capacity beyond zone boundaries to meet power needs.”
Details on the 2018 OMS-MISO survey are available on MISO’s website.
The Organization of MISO States Inc. is a non-profit, self-governing organization of representatives from each state with regulatory jurisdiction over entities participating in the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission organization as defined by the Federal Energy Regulatory Commission (FERC). The purpose of the OMS is to coordinate regulatory oversight among the states, including recommendations to MISO, the MISO Board of Directors, the FERC, other relevant government entities, and state commissions as appropriate.
MISO ensures reliable operation of, and equal access to, high-voltage power lines in 15 U.S. states and the Canadian province of Manitoba. MISO manages one of the world’s largest energy markets, with more than $24.7 billion in annual gross market energy transactions. MISO was approved as the nation’s first regional transmission organization in 2001. The not-for-profit organization is governed by an independent board of directors and is headquartered in Carmel, Indiana.
