CFE Energizes 75 MVA Transformer; 400,000 Users Benefit in Los Cabos

Mexico's Federal Electricity Commission (CFE) energized a 75 megavolt-ampere (MVA) transformer at the Turbogás Los Cabos substation in Baja California Sur on Sunday, July 5, a reinforcement that will benefit approximately 400,000 users in a region of high seasonal demand and historically vulnerable supply.

The equipment, installed alongside a 115-kilovolt (kV) bay, is equivalent to adding a new generating unit to feed the municipality, according to a CFE statement cited by El Sudcaliforniano. Most of the electricity consumed in Los Cabos is currently transported from La Paz, creating transmission losses and vulnerability during summer demand peaks. Baja California Sur is the only electrical system in the country that operates without a connection to the National Interconnected System (SIN), forcing the peninsula to rely entirely on its own generation capacity to meet local demand.

The region has recorded 71 outages since May 2026, according to El Sudcaliforniano, as peak demand approaches 750 megawatts (MW) and has intermittently exceeded available generation capacity, estimated at 65 percent of the 1,100 MW installed. The most severe interruptions occurred on June 23 and 24, with cuts in neighborhoods such as Monte Real lasting up to three hours. The transformer's transport and construction of the 115 kV bay, carried out since June 2026, involved 50 workers from CFE's Generation and Transmission divisions, reported BCS Noticias. The energization benefits 399,648 users in the country's northwest.

CFE maintains additional expansion projects for the northwest transmission network to increase operational reliability. The Baja California Sur peninsula remains the only electrical system in the country without interconnection to the national grid, a condition that structurally exposes it to supply-demand imbalances during peak consumption months.
