Fabricio Ojeda
Location: Merida
Operator: CORPOELEC - Empresa Electrica Socialista
Configuration: 2 X 257- MW Francis
Operation: 2014
T/G supplier: Alstom
EPC: Engevix Engenharia
Quick facts: In May 2003, Alstom was awarded a contract by Cadafe for the electromechanial equipment for the Fabricio Ojeda HPP in the Rio Capara basin. This followed a feasibility study partially financed by the U.S. Trade and Development Agency (TDA) in Oct 1999, although initial project development at the site dates to 1983. The Alstom contract was worth $160mn and financed by Brazilian and French banks. The package included two Francis generating units, complete electromechanical and control systems, hydro-mechanical equipment, transmission equipment, and some related civil works with much of the fabrication undertaken by Alstom Brasil. Project completion was initially scheduled for 2006, but was repeatedly delayed and finally began commissioning in late 2013. The new plant will generate about 1.8 Twh/yr. The plant, also known as La Vueltosa, is named after a prominent Venezuelan journalist and political activist.

Quick facts: The construction contract for Guri Dam in Necuima Canyon, was signed in Aug 1963 and the 10 units of the first 2,660-MW stage were commissioned from 1968 to 1978. The next stage involved elevation of the main dam from 215m to 270m MSL, the construction of two additional dams, and the installation of ten, 730-MW generating units. About 70 companies were involved in the EPC work at Guri and the plant cost was approximately $550/kW. The plant was named Raúl Leoni from 1978 to 2000 and then renamed Simón Bolívar. Edelca has a large-scale plant refurbishment program ongoing at present.
