First unit connected at Costa Rica’s 305.5-MW Reventazon hydro project

The first unit at the 305.5-MW Reventazon hydro project in Costa Rica is being connected to the national power grid, news sources are reporting.

A 130-meter-high dam, on the Reventazon River, impounds a reservoir with an area of 6.9 square km. The diversion structure runs 4.2 km from the dam to the powerhouse. When complete, anticipated by the end of this year, the powerhouse will contain five turbine-generator units.

The project is expected to cost US$1.1 billion and is being developed by state-owned electric utility Instituto Costarricense de Electricidad (ICE).

Abengoa of Spain and Siemens of Germany received a contract in 2014 to equip and construct a substation for the project. In addition, Andritz Hydro Gmbh was contracted in 2012 to provide four Francis turbines, auxiliary generators, control systems, and balance of plant. Sistemas de Potencia received a contract that year to provide a main bridge crane.
