Entergy’s proposed natural gas plants now account for one-third of all projects in the Midcontinent Independent System Operator’s (MISO) expedited interconnection queue, according to a Utility Dive report. Roughly 70% of the utility’s planned capacity additions are designated for data centers across Louisiana and Mississippi.
The fast-track process, known as the Expanded Resource Interconnection Service (ERIS), allows generation assets to connect to the grid more quickly than standard timelines. MISO’s queue has swelled with gas-fired projects as electricity demand surges from both data centers and industrial expansion. The inclusion of Entergy’s fleet signals a growing urgency to secure dispatchable power.
Financial details and construction timelines for the gas units remain undisclosed. Entergy has not publicly provided specific capacity figures for each project, though the sheer volume of fast-track applications suggests a concentrated buildout. The plants would add baseload generation to a region increasingly strained by load growth.
Critics argue the fast-tracking of gas projects could lock in fossil fuel dependence for decades, complicating state-level clean energy targets. MISO itself has acknowledged that ERIS does not require the same transmission upgrades as full interconnection studies, potentially deferring grid reliability costs to other ratepayers.
Counter-argument: Supporters contend expedited gas capacity is essential to prevent blackouts as renewable deployment lags behind demand growth. They maintain that ERIS still undergoes reliability reviews and that gas plants can later be used for backup capacity as more renewables come online.
AI context: This brief is based on a single Utility Dive article (verified source) about Entergy’s role in MISO’s fast-track queue. Data center attribution and ERIS process details are drawn from the same report; no independent verification of capacity percentages was possible.
