Las Tunas.- Workers of the Construction and Assembly Company of the province, now undertake the its casting. Abdo Salah Alnumair, main investor of the Provincial Construction and Assembly Company, told the Cuban News Agency, that concrete is being deposited -300 cubic meters- in a cavity 2.70 meters deep and 16 in diameter, similar to the seven finished earlier.

The conditions for the construction of the park began to be created in Las Tunas since 2013; first by opening trails between the weeds, the construction of roads and other induced works; while 22 of the 34 wind turbines that will be located, as well as the ferrules that will join the bases with the first section of the towers are already near that enclave of the north coast of the municipality of "Jesús Menéndez."

The country's decision to build the park in this territory was confirmed after checking that the wind speed at a height above 50 meters is about 6.8 meters per second; hence also approved La Herradura 2 (LH-2), very close, which is already under construction.

La Herradura 1 will have 34 wind turbines of 1.5 MW, and La Herradura 2, 20 of 2.5, contracted in the People's Republic of China; but their capacity of generation is the same, hence each one will produce more than 150 GW/hour per year, which means that when both are into operation can save about 80 thousand tons of fossil fuels, and stop emitting 250 thousand tons of C02.

These are calculations of specialists on the subject, who clarify that real figures will depends on weather conditions, wind speed stability and wind turbines efficiency.

LH-1 is structured in five circuits, four of seven wind turbines, and one of 6; and according to the start-up program, the park will begin to be operated by circuits as the bases are finished and the towers are assembled.

"No circuit has been completed yet, because our work strategy is to cast where there is less water in the cavities, so that, for example, we work now at the number one and then at 22," Salah Alnumair explained. Due to the high size of the technology, towers that exceed 30 meters, and gigantic blades, the country plans to use special cranes contracted abroad.

At the same time, a substation is being built in the area that will transfer the energy generated by LH-1 and LH-2 to the National Electroenergetic System.

Because of the power of these parks, the largest in Cuba, which together can generate 101 MW, in addition another one projected in the municipality of Manatí -also to the north of Las Tunas- with foreign financing, and the operation of three photovoltaic solar parks; Las Tunas is emerging as the first province that change its energy matrix from the third decade of the present century.
