Bolivia's Warnes II wind farm in Santa Cruz has cleared 90% physical completion, according to ENDE's report on a 25 September inspection by European ambassadors. Once finished, its ten turbines will feed 45 megawatts into the national grid.
The milestone matters because no start-up date has been made public, and the coming weeks of testing will show whether what ENDE calls its fifth wind plant arrives on time.
From 84% to 90% in Under Four Months
On 9 June, ENDE put physical progress at 84.43% and confirmed that six turbine platforms had been handed over. By 26 August, the state company said the total had climbed past 87%, and that the first unit, labeled AG14, was fully raised.
The September inspection then recorded progress above 90%, a gain of more than five points in roughly three and a half months. That figure comes from ENDE's official report, not from an independent audit by the visiting diplomats.
Chinese Machines, French Money
The turbines are Windey WD156-4500 models. A first lot of components came ashore at Puerto Jennefer in late January 2025, and once installed each unit stands about 120 meters tall and weighs around 200 tons, ENDE says. A second, larger haul of blades, nacelles, tower sections and hubs began moving in late May 2026.
The French Development Agency is backing the project with more than 66 million euros. Three contractors share the work: ENDE Corani on civil works, PowerChina Zhongnan on supplying and assembling the machines, and Ingener on the substation.
Ingener is building the substation that ties the wind farm to the grid, and PowerChina is also responsible for testing and start-up. None of the official updates reviewed gives a completion percentage for the substation.
That gap is significant because a finished turbine delivers no electricity until the connection is live.
Two Output Estimates, One Conservative Choice
In June 2024, Windey said the site could yield 150 GWh per year, as reported by Windpower Monthly. ENDE's more recent projection is about 100 GWh, or 100,682.93 MWh, a number the company itself says still awaits official technical verification. This article uses the lower, owner-supplied estimate.
By our own arithmetic, 100 GWh from 45 MW implies a capacity factor near 25%, while 150 GWh would require about 38%.
What It Means for Bolivia's Wind Fleet
Windpower Intelligence counted 135 MW of installed wind capacity in Bolivia in June 2024. Adding 45 MW would expand that by a third, to about 180 MW, assuming nothing else has entered service since.
ENDE presents Warnes II as its fifth wind plant, and the official report credits it with cutting more than 69,000 tons of CO₂ a year.
Europe Reaffirms Existing Backing
Ambassadors from five European countries toured the site with Vice Minister of Electricity and Renewable Energies Rudy Peredo and ENDE president Mario Larrain. EU delegation head Jaume Segura Socías praised the project, and French ambassador Olivier Fontan said France keeps a 216 million euro portfolio for renewable energy.
The report describes the visit as a reaffirmation of support already in place and mentions no new funding. Peredo used the occasion to argue that diversifying the energy mix should also create quality jobs and industrial value for young Bolivians.
When Windey signed its supply deal, Windpower Monthly noted the farm was expected online before the end of 2024. It is now late September 2026, and the official updates reviewed here offer no commissioning date.
The latest turbine count dates from August, when one unit stood complete. No September tally has been published, so how many machines remain is unknown.
