The Kwanza River Hydroelectric Cascade and Laúca Dam
Across the middle Kwanza River, huge modern dams generate clean electricity from fast water flows to power homes and factories across Angola.
The Powerful Waters of the Kwanza
The great Kwanza River starts in the high green hills of Bié and flows 960 kilometers to the Atlantic Ocean.
In the middle valley, the river drops down steep rocky canyons with a total fall of more than 300 meters.
Engineers built the huge Laúca Dam with strong concrete layers that reach a height of 132 meters.
The wide lake behind the dam holds 5.5 billion cubic meters of water to supply electricity all year.
Workers built the top crest of the dam 1,075 meters long across the deep river gorge.
The plant releases a steady ecological flow of fresh water every day to keep river fish healthy.
Underground Power and Giant Turbines
Workers carved a giant room deep inside hard granite bedrock to protect the heavy electricity machines.
The main underground powerhouse contains six vertical-axis Francis hydraulic turbines that turn fast in rushing water.
A smaller river station with a 65-megawatt turbine creates extra clean energy from passing water currents.
Together, the turbines generate 2,069 megawatts of electric power to make Laúca the largest power plant in Angola.
Six large steel pipes called penstocks drop water over 200 meters down into the spinning turbines.
After turning the metal wheels, clean water flows through long tailrace tunnels back into the river.
The Chain of Mega-Dams
Laúca works together with the older Capanda dam upstream and the upgraded Cambambe dam downstream.
The deep Capanda reservoir stores water during heavy rains so downstream plants always have steady river water.
A big improvement project made the curved Cambambe dam 20 meters taller to generate much more clean electricity.
Builders are also constructing the new Caculo Cabaça dam to add even more power to the middle valley.
The national public power company called PRODEL operates all these big river dams together from modern control rooms.
These clean river dams now produce over 70 percent of all the electricity used across the nation.
Powering Cities and Growing Industries
Tall steel towers carry strong 400-kilovolt transmission lines from the river dams directly to the capital city.
The state grid company called RNT connected regional power networks into one single unified national system.
Abundant river electricity helps government programs expand household power access toward 50 percent across rural areas.
Cheap and reliable river power runs big cement mills, steel works, and food processing factories near major cities.
Angola will soon connect its power grid to the Southern African Power Pool to sell extra clean electricity.
Generating clean river energy saves hundreds of millions of public dollars by eliminating expensive diesel fuel subsidies.

Heavy steel penstocks drop rushing reservoir water over 200 meters into the spiraling metal casings of the turbines.
Discharged water exits the spinning turbine runners and returns smoothly to the lower river through concrete tailrace tunnels.
The Chain of Mega-Dams
Laúca serves as the central anchor of a coordinated river cascade that includes Capanda upstream and Cambambe downstream.
Water storage in the large Capanda reservoir regulates wet-season runoff, maintaining reliable downstream water volume for power generation.
Engineers completed a complex heightening project that raised the historic Cambambe arch dam by 20 meters.

National power carrier RNT built long interconnecting lines to merge regional electrical grids into a synchronized transmission network.
Plentiful hydroelectric energy enables public electrification initiatives to expand domestic household access toward 50 percent.
Stable electrical power drives economic modernization, energizing large cement mills, metallurgy factories, and agro-industrial plants.
Angola prepares cross-border transmission connections to participate in the Southern African Power Pool and export clean surplus energy.
Relying on abundant domestic water power saves the national treasury huge expenses by reducing costly diesel fuel subsidies.
