Abstract
A method for installing an electric power plant comprises preparing a plant yard in the form of a shallow pool connected to a water area. The electric power plant is in a package form comprising a floatable base, and is mounted on a submersible barge and towed. Near the plant yard, the package is unloaded and moved into the plant yard when the water is at a high level. Water is then introduced into a ballast tank of the base of the package to cause the package to sink onto the foundation forming the bottom of the pool.
