Colombia Faces US3.7 Billion in Investor Claims as Its Energy Cushion Flips to Deficit
COLOMBIA · ECONOMY
Key Facts
—What happened: Investors are claiming COP$73.8 trillion (US$23.7 billion) from Colombia in arbitration cases.
—How fast it grew: Claims stood at COP$59.9 trillion (US$19.3 billion) in mid-2025, a year and more ago.
—The real story: The energy cushion flipped from a 2 percent surplus in 2022 to a 4.4 percent deficit in 2026.
—The catch: Claims are demands, not debts, and Colombia won five of the nine investment cases concluded.
—Who is suing: Thermal power generators, toll-road concessionaires and a US treasure-hunting firm lead the list.
—What comes next: A new legal defence chief, Germán Calderón España, inherits the docket from the outgoing team.
Colombia faces COP$73.8 trillion (US$23.7 billion) in arbitration claims, according to an analysis published by Semana. The same magazine says the country burned through its energy surplus in four years. It also finds that mining lost ground under 333 new rules.
The claims add up to COP$73.8 trillion
The number comes from Alejandro Linares, a former president of Colombia’s Constitutional Court. He analysed the docket for Semana as the outgoing administration handed over power.
Colombia closed the term with 19 active international investment arbitrations. Another 16 disputes sat in the pre-arbitration stage.
Together their claims reach COP$73.8 trillion (US$23.7 billion). A year earlier, in mid-2025, the agency’s registry showed COP$59.9 trillion (US$19.3 billion).
The single largest claim is Sea Search Armada, at COP$33.8 trillion (US$10.9 billion). The US firm has fought Colombia for decades over the San José galleon shipwreck.
The catch: Colombia wins most of these cases
The headline figure measures what investors demand, not what the state owes. That distinction is the whole story.
Between August 2022 and July 2026, nine investment cases concluded. Colombia won five outright, lost three and settled one.
Only one award against the state became final. That was Glencore I, for US$20.7 million.
The settlement was the 2025 agreement with Aris Mining under the Canada trade deal. It avoided an estimated US$380 million award and required no cash payment.
The state’s legal defence agency, known as Andje, says it avoided convictions worth more than COP$545 trillion (US$175 billion) in 2025 alone. Its success rate approached 81 percent.
Defence is also cheap by regional standards. Colombia spends about US$2.5 million per international case, less than half the Latin American average of US$5.6 million.
Where the energy cushion went
The claims wave connects to a second Semana finding. Colombia’s firm-energy balance went from a surplus near 2 percent in 2022 to a 4.4 percent deficit in 2026.
The figures come from a report by the outgoing mines and energy minister, María Nohemí Arboleda. The system now faces a possible power deficit for 2026-2027.
The timing is bad. A strong El Niño weather pattern is beginning. El Niño means less rain for the dams that generate most of Colombia’s electricity.
New capacity is not arriving on time. Of 4,475 megawatts of generation expected for 2026, only 15.5 percent has entered operation.
Transmission is late too. Close to 60 percent of projects show delays, and the grid logged 216 overload disconnections between April and July 2026.
Gas imports and the Air-e hole
Gas makes the picture tighter. Colombia now imports 30 percent of its national demand, and reserves keep shrinking.
The Caribbean distributor Air-e shows the financial damage. Its equity went from a positive COP$2.22 trillion (US$714 million) in 2023 to negative territory.
Air-e posted a net loss of COP$1.15 trillion (US$370 million) in 2025. The state intervened in the company, and that intervention now feeds new claims.
Two thermal generation groups went to the World Bank’s arbitration centre in 2026 over the electricity crisis. Spain’s Termocandelaria Power claims more than US$198.4 million.
The second claimant is Glenfarne–EnfraGen, owner of plants in Barranquilla, Santa Marta and Palmira. It alleges a lack of gas for its plants and uncertainty over backup payments.
Roads, tolls and a COP$5.3 trillion lesson
The costliest awards did not come through the state’s defence agency at all. The infrastructure agency ANI litigated alone and lost.
Three cases produced COP$5.3 trillion (US$1.7 billion) in awards and one settlement. The Ruta al Mar award alone was COP$3.57 trillion (US$1.15 billion) on 30 April 2026.
Perimetral Oriente de Cundinamarca added COP$1.3 trillion (US$418 million) in June 2026. Autopistas del Caribe settled for COP$0.48 trillion (US$154 million).
Linares traces all three to the same cause. A 2023 decree altered the toll tariff scheme, and the tribunals treated that as the state’s breach.
ANI still has 48 active arbitration tribunals in infrastructure concessions. Their claims total COP$18.3 trillion (US$5.9 billion), double the load of four years ago.
And 333 mining rules later
Semana’s third count covers mining. The magazine tallied 333 new regulations for the sector over the four-year term.
Its conclusion is blunt. After those 333 rules, Colombian mining has lost investment and competitiveness.
Lawyers consulted by the magazine make the same point about energy. Elements on which investors relied were changed by decree or resolution, damaging project bankability.
That is the thread linking the docket, the deficit and the mines. Regulation made during the term is now arriving as compensation claims.
What the new government inherits
President Abelardo De La Espriella’s team takes over with a full file. Germán Calderón España is the new director of the state’s legal defence agency.
Linares sets three priorities. Prevent the damage in the first place, centralise all cases under one system and settle more disputes before they reach a tribunal.
One more risk hangs over the list. In March 2026 the previous government announced a withdrawal from the World Bank arbitration system, and pre-arbitration claims rose after the announcement.
