Las Tunas, Cuba.- Workers of the Provincial Construction and Assembly Company, started work on two of the 34 bases to place the wind turbines of La Herradura 1, located on the northern coast of the municipality of Jesus Menéndez, once ready it will be able to generate 51 MW / h.
Likewise, work is being carried out in La Herradura 2, which will have 14 fewer generators, but with a greater power, so that as a whole, it will be able to deliver a similar amount of energy to the National Power Grid.
Engineer Carlos Manuel Quesada Borges, director of the Provincial Construction and Assembly Company, explained to the Cuban News Agency that "starting to cast the first base it's easy to say. However, it is a complex and important process; first the water had to be extracted from the holes -1,70 deep and a radius of 16 meters-, generated by the proximity of the phreatic surface, then the steel is placed and then the casting, for which a large amount of materials is required."
The executive explained that this procedure will be done in each of the bases, for which 50 tons of iron bars and 4,000 bags of P-350 cement should be used, so that 136,00 bags of this material will be used in the 34 platforms of La Herradura 1.
"Now we have new technology for the movement of land, but most of the work was done with the old equipment handled by men in charge of building the induced works, mainly roads to facilitate the entry and exit of special vehicles for the transfer, from Puerto Carúpano, of the components of wind turbines. Each of them has a length of almost 70 meters."
We are also working on the movement of land for the construction of the electrical substation that will transfer to the National Electric Power System, the energy generated by La Herradura 1 and La Herradura 2 wind farms, which together can provide up to 100 MW / h. This would stop consuming about 75,000 tons of fossil fuels in a year, with the consequent elimination of considerable volumes of CO2.
Quesada Borges informed that by taking advantage of the infrastructure created to locate the wind turbines; a third park is planned in the same area, in addition to one in the municipality of Manatí, with foreign investment.
Cuba foresees until 2030 that 24 percent of electricity consumption comes from renewable energy, a program in which Las Tunas is emerging as the first province to depend less on fossil fuels, when the wind farms are activated and the contribution of the three photovoltaic solar parks in operation, fundamentally. This possibility is based on the fact that only La Herradura 1 and La Herradura 2 will be able to generate 101 MW / h, and the current average electricity consumption in the province is 112 MW / h.
