Calgary, AB (February 25, 2026) Enverus Intelligence® Research (EIR), a subsidiary of Enverus, the most trusted energy-only SaaS company that leverages generated AI across its solutions, announced the recently approved High Speed Interconnection Process for PJM, Midcontinent Independent Operators (MISO), and Southwest Power Pool (SPP). We have published new analysis examining how we are reshaping the reliability of the U.S. electricity market across the region. Until 2030.
The EIR found that accelerating interconnection programs could significantly improve regional reserve margins by 2030 and move all three markets towards stronger supply conditions, while increasing the risk of oversupply, especially if power load growth forecasts are lower than forecast. Natural gas production accounts for the majority of the capacity added at short notice, accounting for approximately 69 percent of cleared resources at PJM and 75 percent at MISO.
“While the fast-track interconnection process has significantly improved the grid reliability outlook for several U.S. power markets, it also raises important questions about the long-term market balance,” said Juan Arteaga, an associate at EIR.
“While interconnection queues accelerate and stable power generation continues, some regions could move from undercapacity to oversupply within a decade if load growth is lower than expected.”
Important points:
If interconnection efforts are accelerated and all resources are provided quickly, PJM’s reserve margin in 2030 could rise to around 20%, well above current levels. MISO’s reserve margin is projected to improve to 11% by 2030 and could further increase due to future resource cycle acceleration. SPP could move from an undersupplied electricity market to an oversupplied one, with sudden increases in supply capacity and reserve margins rising to an estimated 19-24% in 2030. Natural gas is rapidly accounting for the majority of electricity generation additions, approximately 69 percent for PJM and 75 percent for MISO, reinforcing natural gas’s role in short-term reliability. Improving power supply conditions are expected to reduce energy market volatility, creating new challenges for the economics of battery storage and existing peaker plants as market constraints ease.
EIR’s analysis leverages proprietary data and modeling and leverages a variety of products including Enverus PRISM® and Enverus AI.
