This spring, Entergy Louisiana asked a team of Tulane Master of Management in Energy (MME) students in the A. B. Freeman School of Business to analyze its tree-trimming and vegetation program. In response, the students developed financial models for potential revenue streams and a proposed change to federal law that would classify the trimmings and vegetation as renewable fuel.
When the student team started on the task, faculty suggested examining whether those costs could be reclassified from operating expenses to capital expenditures, which would allow the regulated utility to earn a return on that expense.
The students went somewhere else entirely.
“They had this whole other idea about trying to get our vegetation clearing, the organic material, limbs and things like that which qualified as a clean fuel source, and to turn it into a revenue stream,” said Harry Barton, who served as assistant general counsel at Entergy Louisiana at the time and is now chief regulatory officer for Entergy New Orleans.
“That’s incredibly creative,” said Barton, who oversaw the students’ work. “It’s nothing anybody here has ever thought of in 100 years of running the business.”
In addition to developing the proposal to qualify the waste as a renewable fuel, the team created financial models for three potential paths: selling the chipped waste to a biofuel facility being built at the Port of South Louisiana; using the material to create biochar, a type of charcoal that’s made by heating organic materials; or creating green hydrogen from the biomass.
