El Cajon
Location: Honduras
Operator: Empresa Nacional de Energia Electricia (ENEE)
Configuration: 4 X 75 MW Francis
Operation: 1986
T/G supplier: Voest, GEC Alstom
EPC: Motor Columbus, CELCA (Impregilo/Losinger/Lublin), CONINCA (Astaldi/Codelfa/Columbus Panamericana)
Quick facts: El Cajon, also known as Francisco Morazán, is the largest hydro plant in Central America outside
Mexico and was built with $750mn in loans from the World Bank and the Inter- American
Development Bank. The 226m, double curvature arch dam is the sixth tallest
in the world and the project was the largest civil engineering project
ever carried out in Honduras. After the reservoir was filled, cracking
began in the grout curtain behind the dam. Extensive grouting work was
required to stabilize the limestone bedrock under the dam, a process
completed in 1995.

Péligre
Location: Haiti
Operator: Electricite d'Haiti (EDH)
Configuration: 3 X 17 MW Francis
Operation: 1971
T/G supplier: Ansaldo
EPC: Ansaldo
Quick facts: This power station in Centre department on the Artibonite River is the most important generating resouce in Haiti but is barely operational due to heavy silting in the reservoir and mechanical problems. The facility was also damaged by Haiti's devastating Jan 2010 earthquake. Development started in the 1930s and the dam was competed in 1956 by the US Army Corps of Engineers and Brown & Root. In Dec 2010, IBD, KfW, OFID, and OPEC jointly funded a 3yr, $48.8mn rehabilitation package for the
Péligre plant to be undertaken by a consortium of Alstom and Compagnie de Montages Electriques a l'Exportation (Comelex).

Rio Blanco
Location: Honduras
Operator: Energia y Transmision SA de CV (Enetran)
Configuration: 1 X 5 MW Francis
Operation: 2004
T/G supplier: Alstom
Quick facts: Rio Blanco went online in Jun 2004, the first such project to
sell Certified Emission Reductions (CERs) under the Kyoto Protocols Clean
Development Mechanism (CDM). The project is in the San Francisco de Yojoa,
60km south of San Pedro Sula. Grupo Terra subsidiary Enetran worked with
Asociacion de Pequenos Productores de Energia Renovable (AHPPER) on the
project. The powerhouse is about 2km below a dam on the Rio Blanco. The
developers signed a 15yr PPA with ENEE and expect to supply 32 GWh/yr on
average to the gird through a 1.5km, 34.5kV transmission line with a
capacity of 34.5 kV. The scheme has a diversion dam, a forebay, a
powerhouse with discharge channel, and an access road. Rio Blanco now
supplies local communities that thus far have not been connected to the grid.
