Mexican utility Comisión Federal de Electricidad (CFE) is finalising a new call to tender for turbine supplies and installation at its 100 MW La Venta II project in the state of Oaxaca. The new call follows the failure of a previous one, issued in February this year, which brought offers from Vestas of Denmark, Spain's Gamesa, Japan's Mitsubishi and American GE Energy. Bids from all four companies were above the turnkey project budget of $112 million. An unfavourable exchange rate and rising steel prices were mainly to blame for the higher than expected prices, said CFE's Alberto Ramos to Latin American news agency Business News Americas. CFE is now adjusting project specifications in order to bring prices within the budget range. Modifications include a reduction in overall installed capacity. Meanwhile, the utility has also put back to August a call for offers to build the project's 18 kilometre feed-in line.
