Who the new energy minister is

Arboleda is an electrical engineer from the National University with more than three decades in Colombia’s power sector. She has led XM, which runs the national grid and the wholesale electricity market, since 2016.

In that role she became the first woman to head the company and a familiar voice on supply reliability during drought and high demand. She has never held political office.

De La Espriella leaned on that record, calling her a technical pick chosen on merit rather than politics. The appointment is meant to reassure investors and markets about a sector he says he inherits in trouble.

A sharp turn on oil and gas

The appointment marks a clear break from the outgoing government of Gustavo Petro. Petro pushed a green transition and curbed new oil and gas exploration; the incoming team wants to put fossil fuels back at the centre.

The stated agenda is a fast one. It includes reactivating oil and gas contracts, reopening exploration including unconventional methods with limits in protected areas, and a review of the state oil company Ecopetrol.

The vice-president-elect, José Manuel Restrepo, has suggested the government’s first two decrees focus on restarting gas and oil exploration. De La Espriella has framed the shift as a fix for a looming risk of energy shortages.

Natural gas is the sharpest worry. Colombia has slid toward importing gas as domestic fields mature, and reopening exploration is the incoming team’s answer to keeping supply and prices under control.

Why it matters for investors and residents

For investors, the pick rounds out a market-friendly economic team alongside finance minister Miguel Gómez. It points to a more predictable, contract-based approach to energy after years of uncertainty.

For residents, one promise stands out. Arboleda has flagged the high electricity tariffs on the Caribbean coast, among the country’s steepest, as an early priority to tackle.
