A consortium led by ALSTOM has won a 92 million euro turnkey series capacitor system (SCS) contract with TRANSELEC, the main Chilean transmission operator, to strengthen its transmission grid. ALSTOM’s share of this contract is 56 million euros.
The consortium, which includes Mitsubishi Electric Company (MELCO), will supply a full turnkey solution to transmit electricity produced by the RALCO 570 MW hydro-power plant within central Chile.
The scope of this project includes the construction of four 500 kV SCS, a new 500 kV/220 kV substation at Charrua, the expansion of two 500 kV substations at Ancoa and Alto Jahuel, the supply of 1,500 MVA autotransformers, 500 kV reactors, a digital protection and control system and all related civil works, erection, testing and commissioning.
By using SCS technology, TRANSELEC can increase the transfer capacity of its 500 kV system, thereby avoiding the costly and time-consuming process of building new transmission lines. The entire infrastructure is expected to be in operation by mid-2004.
