How the World’s Largest Energy Megaprojects Are Built. Mega Engineering Documentary

Discover how the world’s largest energy systems are built, from giant hydropower plants and pumped storage caverns hidden inside mountains to nuclear reactors, solar parks, wind turbines, LNG facilities, offshore pipelines, and ultra-high-voltage transmission towers. This mega engineering documentary follows massive foundations, turbine installation, reactor vessel lifting, tunnel boring, pipe welding, transformer transport, live-line helicopter maintenance, and precision construction where a few millimeters matter. See how engineers build the hidden infrastructure that powers millions of homes and keeps modern cities alive.
