Colombia's mines and energy ministry Minminas has launched calls for bids for the construction of transformers and a substation expansion.
Minminas' planning unit UPME has invited bids to build and operate a 100MW transformer at the 110kV substation in Valledupar, César department.
UMPE is also inviting bids for the procurement, construction, operation and maintenance of the expansion works at the 220kV Valledupar substation and the construction and maintenance of two 100MW transformers at the Río Córdoba substation.
The works are due to begin operations in 4Q16 and are part of seven projects announced in May to improve the Caribbean coast's regional grid and include the 500kV Cerromatoso-Chinú-Copey line, the 220kV Caracolí substation, the 220kV Caracolí interconnection line and the 220kV Termocol line.
