Cabaiguán Solar Park Connected to National Power Grid

After just over two months of assembling its 1,638 solar panel arrays, the Cabaiguán Photovoltaic Solar Park (PSFV)—one of three 21.87-megawatt (MW) facilities under construction in Sancti Spíritus province—was connected to Cuba’s National Electric System today following required technical verifications.

Located near the Arroyo Lajas recreational camping area, the project is part of the Cuban government’s program to transition toward clean energy.

Julio Antonio Hernández Puebla, head of the Comprehensive Project Directorate for these installations at the Sancti Spíritus Electric Company, told Escambray Digital that the site features seven inverters, totaling 21.87 MW, all now synchronized.

In prior statements to the Cuban News Agency (ACN), Roberto Hernández Rojas, the company’s general director, noted that while panel assembly was initially projected to take three months from resource delivery, collaborative efforts involving local and external organizations accelerated completion to roughly two months.

He highlighted that this site differs from other operational solar parks on the island, which were built using pile-driving technology for easier construction. Due to rocky terrain, the Cabaiguán project required pilarotes—a more time-consuming technique involving excavation and concrete pouring.

Meanwhile, the Tuinucú PSFV in Taguasco municipality has begun panel installation, while the third planned facility in Jatibonico’s El Meso community is in the earthworks phase.

Hernández Rojas explained that once all three 21.87-MW solar parks synchronize this year, alongside 18 MW from seven smaller local installations, Sancti Spíritus will exceed 80 MW of photovoltaic capacity. This expansion will significantly bolster daytime power supply and reduce national fuel consumption.
