Uruguay expands solar energy as electricity demand increases
With an electricity mix fed by approximately 94% renewable sources, Uruguay is already a decarbonisation pioneer. But while 46% of those sources are hydropower, 27% comes from the wind
Reprinted here with permission. Once reliant on exorbitantly priced fossil fuel imports for nearly half of its energy needs, Uruguay has gone from suffering frequent blackouts and power cuts to relative energy sovereignty based almost entirely on electricity generated from a stable mix of wind, solar, hydroelectric, and bioenergy sources.
In 2019 alone, Uruguay exported 2,994 gigawatt hours to Brazil through two international connections, and to Argentina from the Salto Grande Dam—over a fifth of its overall energy generation—adding over $70 million to government coffers.
The map of Uruguay's electrical grid today is starkly different from that of 2008, when the majority of power was generated at a few hydroelectric dams north of Montevideo and the rest at a handful of fossil fuel plants in the capital. It's now possible for the entire grid to run several hours a day entirely on wind power.
Ultimately, all parties agreed on a plan to install “no less than 300 MW of eolic [wind] power and 200 MW of biomass,” as well as to continue searching for fossil fuels on Uruguay's territory. Fridays. A weekly digest of the best of our coverage.
