Costa Rica to build 631 megawatts hydroelectric plant

The Costa Rica Institute of Electricity will start to construct the biggest hydroelectric plant in Central America at the end of next year.

Monday, December 22, 2008

The project called El Diquis will be located between Buenos Aires, Osa, and Pérez Zeledón.

The plant's capacity (631 megawatts) will be equal to one third of the energy park in the country (2,000 megawatts) and will supply electricity to a million homes. The project is scheduled to come online in 2016.

650 MW Hydroelectric Project: Yes or No?

May 2018

The new Minister of Environment and Energy in Costa Rica is opposed to the Diquís project, which the state electricity company has been promoting for ten years, and which consists of building a hydroelectric generation plant in Puntarenas.

While the new leaders of the Costa Rican Institute of Electricity (ICE) announced their intention to refloat the project, which due to unconstitutionality appeals filed against it has remained on paper for years, the Ministry of Environment and Energy has declared its opposition, stating that "... there are no studies or other assessments on the social and economic impact that justify the declaration of national convenience given to the project a decade ago."

Expropriations Could Delay El Diquis Hydro Power Plant

The Costa Rican Electricity Institute (ICE) must expropriate 1.500 lots to build hydroelectric power plant El Diquis in the south of the country.

ICE will have to disburse $60 million to purchase lots and relocate nearby populations. This accounts for 3% of the entire cost of the project, estimated at $2.000 million.
