Mexico’s Federal Electricity Commission (CFE) energized a new 75 MVA transformer at the Turbogás Los Cabos substation on July 5, bringing a significant capacity boost to one of Baja California Sur’s fastest-growing municipalities. The upgrade is part of a broader effort to strengthen the electrical transmission network across northwestern Mexico.
The project required 50 workers from CFE Generation and CFE Transmission. Crews also built a new 115 kV bay at the substation, which connects the transformer to the existing grid as the output for a new generating unit. CFE said the added infrastructure will improve capacity, reliability, and operational safety across the Los Cabos corridor.
Nearly 400,000 Users to Benefit
CFE estimates the upgrade will directly benefit approximately 399,648 electricity users in the Los Cabos municipality. That figure covers residential customers, hotels, restaurants, and commercial properties spread across Cabo San Lucas, San José del Cabo, and surrounding communities.
Los Cabos has long struggled with power outages during peak demand periods. Summer months are particularly punishing, as air conditioning loads spike when temperatures climb above 35°C (95°F). Rolling blackouts and unplanned outages have frustrated residents and business owners alike in recent years.
More Stable Supply, but No Guarantees
CFE said the additional capacity should make the power supply more stable and reduce the frequency of failures. The utility stopped short of promising an end to outages entirely, a realistic acknowledgment given the region’s rapid population growth and tourism-driven demand.
Baja California Sur operates on an isolated electrical grid, disconnected from mainland Mexico’s national system. That isolation makes every megawatt of local generation and transmission capacity critical. The peninsula relies on a mix of gas turbines, diesel generators, solar farms, and wind installations to meet demand.
The Turbogás Los Cabos substation sits within this network as a key node for the southern tip of the peninsula. The 75 MVA transformer adds roughly the equivalent of 75 megawatts of apparent power handling capacity, enough to serve tens of thousands of homes under normal conditions.
Part of a Regional Grid Expansion
The Los Cabos upgrade is one piece of a larger CFE initiative to reinforce grid infrastructure across the northwest. The commission has identified Baja California Sur as a priority zone due to its population growth, tourism development, and grid vulnerability. Los Cabos alone has seen its population nearly double over the past two decades, putting constant pressure on electrical infrastructure that was originally sized for a much smaller community.
