MISO is the operator for the electric grid for Arkansas, Louisiana, Mississippi and Texas and a dozen other states all the way up to the Canadian border and coordinates long-range transmission planning (LRTP) .
In 2013, Entergy agreed to join MISO (Mid-Continent System Operator) after an unanimous Federal Energy Regulatory Commission (FERC) vote. Prior to this, Entergy was under a Department of Justice (DOJ) investigation for anti-competitive practices related to its transmission system and had agreed to sell its transmission assets because of it.
Over a decade later, Entergy has yet to sell its transmission assets nor go through MISO’s Long Range Transmission Plan (LRTP) process to build transmission lines that benefit its consumers. MISO estimated that Entergy’s $3.3 billion transmission investment in 2023 had a .01 net benefit to consumers.
