In Peru, the system is based on interconnected electric transmission lines to 220 000 volts (or 220 KV-KV), which carry electric power from the central fundamental and major Mantaro power plants across the country.
Then, using the processors in the country many substations, tension is being reduced to meet ever-smaller requirements. Thus, from the initial 220 KV to 138 KV is passed, then to 66 KV, 33 KV, etc., Up to the voltage of only modest 220 volts we receive in our homes.
But now Peru is beginning to dabble in the transfer to a higher voltage, the same as that used in developed countries. It is with this object that has just opened its first line to 500 KV.
500 KV: line projected northward
line is Chilca-The Plain-Zapallal, which has been constructed by the Consortium Transmantaro, belonging to the Colombian company Electric Interconnection (ISA ), licensee of this network and already present in other electrical enterprises in our country. The work, which connects substations of the three areas mentioned, and has demanded an investment of U.S. $ 130 million, including networks of 220 KV and a total of 300 kilometers, passing through several districts in the provinces of Lima (San Bartolo, Punta Negra, Lurin Pachacamac, Cieneguilla, Ate Vitarte and Carabayllo) Chosica (Lurigancho) and Huarochirí (San Antonio).
With the work being incorporated into the national grid much of the energy generated at the new and very powerful pole Chilca thermoelectric (made by plants and Kallpa Chilca I), which, operating from the Camisea natural gas, sum and power more than 1,100 Megawatts (above the hydroelectric complex Mantaro), which will grow further next year when Kallpa opens its turbine combined cycle.
While this line to 500 KV is only 94 kilometers long, is important because it constitutes the starting point for what is coming, as soon Zapallal from the substation will be extended to Trujillo, with an additional tour 530 kilometers in the north leading to no less than 600 MW. And there will continue to Chiclayo.
addition, projects southward, as the company Abengoa will build, within the framework of a concession, a line of 761 kilometers, will plant becoming Mantaro to Moquegua. There are also plans to build a similar line from the substation Chilca, which will be completed by Marcona and capital in Moquegua. With them, this area of \u200b\u200bthe country significantly improve its supply, and large mines will operate smoothly.
500 KV: projected lines to the south.
As you can see, there are plans for transforming the electrical system to go with these lines, which are not only high capacity, but much more efficient than existing lines. It happens that the higher the voltage decreases the resistance of the conductor, so that reduce transmission losses. And that, ultimately resulting in lower costs and tariffs.
I reviewed is essential at a time when Peru, due to its high economic growth rate, is requiring the urgent expansion of its power capabilities, both in generation and distribution, to avoid getting too close the demand supply . Even better if it is done with projects involving greater efficiency and lower costs.
