Los Cabos Blackouts: Solar Battery Backup While the Grid Catches Up
Updated October 29, 2026 · By Cabo Solar Experts
Los Cabos blackouts hit a record in summer 2026, and the new power plants planned for Baja California Sur are years away. Solar battery backup lets a home or business in Los Cabos make and store its own electricity now, so the circuits included in the backup design keep running when CFE power drops.

What did the news report about blackouts in Baja California Sur?
On October 27, 2026, Semanario ZETA reported that hotel owners in Baja California Sur say the state still has no short-term strategy for its energy crisis. According to the Centro de Energía Renovable y Calidad Ambiental (CERCA), summer 2026 brought 120 blackouts, mainly in La Paz and Los Cabos. That beat the previous record from 2019, when almost 70 outages were registered. (Source: Semanario ZETA, “Hoteleros reclaman estrategias a corto plazo para combatir la crisis energética de BCS”.)
Agustín Olachea Nogueda, president of the hotel and tourism business association EMPRHOTUR, said federal authorities have not yet set a short-term route to fix the problem. He welcomed that work is starting, and asked that planning look 15 to 20 years ahead, not just four or five.
When will the new power plants for Los Cabos be ready?
CFE’s projects for Baja California Sur include two solar-thermal plants and an internal-combustion power plant for Los Cabos, which together would add 340 MW of generation to the state. ZETA reports these projects will take years to finish, and Olachea described a timeline of three, four or five years before they are installed.
That is good news for the long term. In the meantime, every home and business in Los Cabos still needs power through the next summers. That gap is where on-site solar and battery backup help.
How does solar battery backup work during a Los Cabos blackout?
A solar battery backup system has three main parts working together: solar panels, a hybrid inverter and lithium batteries. During the day, the panels power the home and charge the batteries. When CFE power goes out, the hybrid inverter switches the backed-up circuits to the batteries, and the panels keep recharging them while the sun is up.
- Solar panels make electricity on your roof every sunny day.
- A hybrid inverter lets the panels, batteries and grid work together according to the system design.
- Lithium batteries store energy for the evening and for outages.
One important point: a standard grid-tied solar system with no batteries usually shuts off when the grid goes down, for the safety of line workers. If backup during blackouts is your goal, the system has to be designed for backup from the start.
What can a battery backup keep running?
It depends on the battery size, the inverter capacity and what you plug in. Cabo Solar Experts sizes each system around the loads you care about most, such as:
- Refrigerators and freezers
- Lights, fans and outlets
- Internet, Wi-Fi or Starlink
- Water pumps
- Selected air conditioners, when the system is sized for them
We never promise unlimited backup or an exact runtime without your load information. Instead, we look at your CFE bill and ask how many air conditioners you want running at night, then design the battery bank to match.
Which system is right for my home or business in Los Cabos?
Hybrid solar with battery backup
Best for homes and businesses that stay connected to CFE but want power during outages. You use solar and stored energy first, and the grid fills in the rest. Read more on our solar battery backup in Los Cabos page.

Frequently asked questions
How many blackouts did Los Cabos have in 2026?
According to CERCA, cited by Semanario ZETA, Baja California Sur had 120 blackouts in summer 2026, mainly in La Paz and Los Cabos. That beat the 2019 record of almost 70.
When will CFE fix the power supply in Los Cabos?
CFE’s planned two solar-thermal plants and internal-combustion plant would add 340 MW, but local hotel leaders say they will take three to five years to be installed.
Does solar work during a blackout in Los Cabos?
Only if the system has batteries and a hybrid inverter designed for backup. A standard grid-tied system without batteries normally shuts off when CFE power goes out.
Can a battery backup run my air conditioning?
Selected A/C units can run when the battery and inverter are sized for them. Cabo Solar Experts asks how many units you want at night and sizes the system to match.
Do I need to stay connected to CFE?
No. A hybrid system stays connected to CFE and uses batteries during outages, while an off-grid system runs fully on solar and batteries.
