Ensenada’s municipal government is moving forward with plans for a large-scale solar energy facility that officials say could generate enough electricity for 36,000 homes. Mayor Armando Ayala Robles announced the project during a working session this week, describing it as a step toward energy self-sufficiency for one of Baja California’s fastest-growing cities.
Ensenada Consumes More Electricity Than It Generates
The proposed solar farm would be built on a 100-hectare site (about 247 acres) in an unspecified location within the municipality. According to city officials, the facility would have the capacity to produce roughly 100 megawatts. That figure would represent a significant addition to the region’s power grid, which currently relies on generation capacity located outside the municipality.
Ensenada imports most of its electricity. CFE, Mexico’s federal electric utility, operates the regional grid. But local generation has not kept pace with population growth and commercial expansion. The city’s population surpassed 600,000 in the 2020 national census, and development along the coastal corridor south toward San Quintín has accelerated since then.
Baja California as a whole sits in an unusual energy position. The peninsula’s northern grid connects to both CFE’s national system and the U.S. grid through cross-border transmission lines near Tijuana. But Ensenada, roughly 80 miles south of the border, sits at the end of that transmission chain. During peak summer demand, voltage drops and brownouts have affected colonias on the city’s eastern edges.
Solar potential in the region is strong. Ensenada averages roughly 300 days of sunshine per year. The arid valleys east of the city, particularly around the Ojos Negros and Real del Castillo corridors, receive some of the highest solar irradiance levels in the state. Several smaller private solar installations already operate in the wine country zone of the Valle de Guadalupe, where vineyards and boutique hotels have installed rooftop systems to offset high commercial electricity rates.
Municipal Solar Projects Are Rare in Baja California
What makes this proposal notable is the municipal government’s direct involvement. In Mexico, electricity generation is constitutionally controlled by CFE at the federal level. Private and municipal solar projects must navigate a permitting framework overseen by the Comisión Reguladora de Energía (CRE), the national energy regulator. Under reforms pushed by former President Andrés Manuel López Obrador between 2021 and 2024, the rules for non-CFE generation tightened considerably.
Those federal restrictions discouraged many municipal governments from pursuing their own renewable projects. Tijuana, for example, shelved a 2022 proposal for solar canopies over public parking lots after encountering permitting delays. Mexicali, which has long generated geothermal power through the Cerro Prieto plant operated by CFE, has no municipal-level solar projects of comparable scale.
Ayala Robles did not specify whether the Ensenada project would operate as a public-private partnership, a direct municipal investment, or a concession to a private developer. That distinction matters. A fully municipal project would face stricter federal scrutiny. A private developer selling power through a bilateral contract could potentially move faster, though recent federal policy has made such contracts harder to secure.
The mayor stated that the project aligns with broader infrastructure goals for the municipality, including water and road improvements. City officials also referenced potential job creation during construction, though no specific employment figures were provided.
Electricity Costs and Reliability Affect Property Owners Directly
CFE electricity rates in Baja California are structured by tariff zones. Ensenada falls under the Tarifa 1 residential rate, which uses a tiered pricing system. Households consuming more than 850 kilowatt-hours per billing period in summer months pay the highest “DAC” (Domestic High Consumption) rate, which can push bimonthly bills above 5,000 pesos (roughly $280 USD). Properties with pools, air conditioning, or electric water heaters commonly cross that threshold.
Reliability is the other concern. Power outages in Ensenada’s hillside colonias, including areas popular with foreign homeowners like Chapultepec and parts of El Sauzal, have increased during summer heat events over the past three years. A local generation source could reduce strain on transmission lines running south from Tijuana and Rosarito, where CFE’s main thermal plants for the northern Baja grid are located.
No construction timeline has been announced. The city government indicated that environmental impact studies and federal permitting would need to proceed before any ground is broken. The next formal update is expected during the municipality’s infrastructure planning sessions scheduled for later this year. The project details were first reported by Punto Norte.
