CARMEL, Ind. – MISO projects adequate power reserves to meet 2017 summer peak demand. MISO expects summer demand to peak at 125 gigawatts, with 148.5 GW of available capacity.

The summer peak demand forecast was released during today’s Summer Readiness Workshop, a feature of MISO’s reliability planning efforts.

“MISO continues to work closely with stakeholders to ensure the reliability and efficiency of the bulk electric system,” said Todd Ramey, vice president of system operations. “We appreciate the ongoing efforts of load-serving entities and states to ensure adequate resources are in place.”

The MISO region’s 23.5 GW reserve in 2017 – providing an 18.8 percent margin – is up from 2016 primarily due to a reduction in projected peak demand in the MISO North and Central regions.

MISO's seasonal assessments review projected demand and resources for the MISO footprint and assess adequacies and risks for upcoming seasons. These projections are compared to the minimum Planning Reserve Margin requirements established under MISO's Tariff. The margin requirement for 2017 is 15.8 percent.

MISO holds regular Summer Readiness Drills with MISO operators, members and Market Participants to review emergency operating procedures and test communication protocols. All MISO stakeholders can also participate in the Summer Readiness Workshop to understand how the region prepares for potential extreme weather conditions.

MISO works closely with stakeholders to address long term resource adequacy needs through a range of efforts. This includes the increased transparency around future resource projections provided by the Organization of MISO States  – MISO survey. Additionally, MISO continues to work with stakeholders to improve MISO’s resource adequacy construct around locational and seasonal issues.
