Optimizing the LCOE of Navojoa’s solar PV plant

The project has been carried out in the State of Sonora, municipality of Navojoa, Mexico. This photovoltaic plant integrates 257 MWp, deploying more than 674.000 panels to produce green and clean energy, avoiding releasing tons of greenhouse gases.
Ormazabal has helped to optimize the LCOE of this photovoltaic plant, by modifying the original plant design which consisted of a single busbar of more than 3000 A, into two busbars rated at 2500 A, with our primary distribution technology products of the cpg.0 family.
This solution makes the project cost-competitive by decreasing the short-time withstand and rated currents per secondary winding of the power transformer, and thus reducing grid connection infrastructure expenses.
It is also important to note that this solution increases the availability of generation in the event that the downstream infrastructure of the power transformer suffers a failure.
