Cuba is expanding the use of solar energy technology at telecommunications facilities in Ciego de Ávila as authorities seek to improve the reliability of phone and internet services during the country’s energy crisis.

ETECSA officials said photovoltaic systems are being prioritised at telecommunications sites in municipal centres and hard-to-reach communities, where electricity shortages can affect fixed-line, mobile and data services.

The province currently has 22 photovoltaic systems serving municipal centres, alongside around 20 technology sites with solar backup. ETECSA described the programme as part of short-, medium- and long-term efforts to increase the energy autonomy of the telecommunications sector.

The initiative comes as Cuba’s telecommunications infrastructure faces pressure from prolonged power disruptions. ETECSA has acknowledged that electricity shortages can shut down technology sites and reduce the availability of communications services.

Solar-powered telecommunications infrastructure could provide an additional energy source for critical communication equipment and help maintain connectivity in vulnerable communities.
