A structural break is underway, driven by data centers and other factors, but MISO load growth is highly uneven and sometimes counterintuitive. With baseload growing faster than peak and less-populated areas growing faster than urban centers, market participants must keep pace with new and changing grid dynamics.
Understand the nature and drivers of MISO's load growth:
MISO’s “current” load growth trajectory matches its “high” scenario from just two years earlier, and it’s concentrated in the North and Central zones which have been historically slower growing than the South. Yet significant siting-driven uncertainty remains, and regulatory responses could dampen the effects of large loads on the grid.
A decade-long equilibrium is undergoing a regime change, with net energy demand in MISO now projected to grow 63% through 2046. This paper looks at both the actual observed trends in MISO in recent years as well as its 2026 Long-Term Load Forecast and the specific forces reshaping demand from the Gulf Coast to the Dakotas and Manitoba.
