(The Center Square) — Louisiana regulators are grappling with how to power a wave of large scale industrial power users without shifting the cost onto existing customers, as demand for electricity surges alongside economic development efforts.
The issue took center stage Thursday at a Louisiana Public Service Commission technical conference, where regulators, utilities and staff debated whether the state needs clearer rules for large electricity users such as data centers and heavy industry.
The push comes as Louisiana courts major investment from power-intensive projects, including data centers, natural gas plants and steel mills. Those facilities require substantial electricity, raising questions about how utilities can meet new demand while shielding current ratepayers from higher costs.
Commissioner Davante Lewis said the commission is working toward establishing “large-load tariffs,” formal rate structures that would define how major users pay for power, transmission upgrades and other infrastructure.
“There is a committed goal to have large-load tariffs,” Lewis said, adding the effort remains in early stages.
Other states have already adopted similar policies, with thresholds ranging from 5 megawatts to 100 megawatts or more, Lewis said. More than half of states have some form of large-load tariff.
“We do not want to be left behind,” Lewis said in a social media post.
The discussion coincides with the commission’s “Lightning Initiative,” which allows utilities to seek expedited review of major infrastructure projects tied to large new power demands. The initiative aligns with an executive order from Gov. Jeff Landry aimed at accelerating economic development.
Large-load tariffs are intended to ensure that new, high-demand customers cover the costs they impose on the system, including generation and transmission upgrades. Supporters say the approach protects existing customers from subsidizing major projects. Critics argue overly rigid rules could complicate negotiations with companies considering investments in Louisiana.
Entergy declined to take a position following the meeting. Regulatory affairs manager Larry Hand referred questions to the company’s press office, which did not respond to a request for comment.
Regulators also discussed other options, including requiring large-load customers to directly fund the infrastructure needed to serve their projects.
Lewis said the conference builds on broader commission efforts to establish clearer guidelines for handling large-scale electricity demand as Louisiana competes for new industry.
“This conference is correlated to the Lightning amendment,” Lewis said in an interview. “We’re looking at guidelines for how to get approval.”
Louisiana’s current large-load guidelines say utilities should identify transmission upgrades needed because of a new load and demonstrate that network and interconnection costs caused by the load are fully assigned to that load. The guidelines are non-binding, but warn that failure to address the commission’s concerns creates risk for the utility.
Lewis said other states are considering requirements that certain large-load customers bring their own backup generation or meet other conditions before connecting to the grid.
One unresolved question is how much responsibility data centers should bear for the infrastructure needed to serve them. Asked whether data centers should be required to pay for and operate more of their own power infrastructure, Lewis said the issue is complicated because those companies generally do not want to function like utilities or take on the responsibility of maintaining electric infrastructure.
Nationally, the growing demand for electricity is drawing federal attention, according to Dana Shelton, an attorney for commission outside staff. The Federal Energy Regulatory Commission has said it will act by June 2026 on a proceeding involving the interconnection of significant new electrical loads, including data centers, to the transmission system.
Shelton said the federal activity has raised concerns among some states about jurisdiction and local control. While federal regulators oversee interstate transmission, states traditionally regulate how retail electric service is provided, including rates and utility service obligations.
The question for Louisiana, regulators said, is how to make sure utilities can serve major new projects without shifting inappropriate costs to existing customers.
