June 19 (Renewables Now) - Mainstream Renewable Power and Chilean power transmission company Transelec SA signed last week a contract to design and build a transmission line that will connect the Irish firm’s 293 MWp of solar parks to the National Electric System.
Mainstream is currently developing two solar photovoltaic (PV) projects, the 170-MWp Rio Escondido and the 123-MWp Valle Escondido, in Tierra Amarilla in the Atacama region. The contract with Transelec will deliver a 55.5-km long 220 kV transmission line that will evacuate electricity from the solar farms. The power will then be transported to Transelec’s Cardones substation, the Irish renewable energy company said Tuesday.
In the first phase, the transmission line will connect the Rio Escondido farm to the national grid. Valle Escondido will be connected at a later stage.
Construction of the transmission line will begin later this year.
Transelec has connected almost 64% of the renewable energy capacity built in Chile in the last five years.
