Guatemala Does Not Lack Capital. It Lacks Conductors.

Every August the Administrador del Mercado Mayorista publishes a table that ought to be read aloud in Congress. It lists the plants that were ready to generate and the hours they were told not to. This year the column runs to four pages.

The reason is not demand. Demand grew four percent, as it has for a decade. The reason is that the transmission lines between the hydro basins of Alta Verapaz and the load centres of the capital and the south coast are full, and have been full since 2022. A generator behind a congested line is a warehouse with no road. Its owners are paid for capacity they cannot deliver, and factories in Escuintla buy diesel-fired power at three times the spot price to make up the difference.†

A megawatt that cannot travel is not a megawatt. It is a promissory note.

The fix is well understood and poorly loved. Transmission is a public good that nobody wants to be photographed beside. It takes a right of way, a decade of hearings, and a tariff that raises every bill by a few centavos so that every bill can later fall by many. The Plan de Expansión del Sistema de Transporte has named the same three corridors since 2018. Two remain unbuilt.

We calculate that the congestion premium paid by industrial users in 2025 exceeded the capital cost of the missing lines. That is: Guatemala has already paid for the wire, and does not have it.
