Colombia’s proven natural gas reserves have contracted by more than half since 2018, fundamentally altering the country’s energy balance sheet.
The long-term erosion of the resource base has shifted Colombia from a net exporter of gas and power to its neighbors into a net importer, just as meteorological forecasts point to a strong El Nino event that threatens to exacerbate domestic supply constraints.
Data reported by La República indicates that proven natural gas reserves fell by 54.
The structural deficit in domestic production capacity leaves the national grid vulnerable to seasonal shocks.
With hydroelectric generation expected to face pressure from drought conditions associated with El Nino, the reliance on imported gas for thermal power generation is likely to increase.
This dynamic introduces volatility into regional energy markets, as Colombia competes for supply in a tighter Latin American gas landscape.
Data reported by La República indicates that proven natural gas reserves fell by 54.6% between 2018 and 2025.
