Mexico's electricity sector is federally owned and controlled by the Comisión Federal de Electricidad (CFE). The standard light voltage in Mexico is 127 volts (V) at a frequency of 60 Hertz (Hz). However, Mexico has two types of voltage: single-phase and three-phase. Single-phase voltage is 120 volts phase-neutral and 240 volts phase-phase, while three-phase voltage is 127 volts phase-neutral and 220 volts phase-phase. Mexico's electrical frequency of 60Hz is the same as that used in the US and parts of South America, and is due to colonial and industrial influence.

What You'll Learn
Mexico's electrical frequency is 60 Hz
The choice between 50 Hz and 60 Hz is a quirky relic of early electrical engineering, influenced by competing industrial ambitions and practical choices. During the development of commercial electric power systems in the late 19th and early 20th centuries, many different frequencies were used. Standardization was a slow process due to the large investments in equipment at specific frequencies.
Today, about 40 countries use 60 Hz, while most other countries typically run on 50 Hz. The induction motor, commonly used in household appliances and power tools, works well with frequencies around 50 to 60 Hz. When converting between these two frequencies, there is often a performance loss due to adjustments in engine RPM, affecting the overall kW or kVA output.
In Mexico, the standard light voltage is 127 volts (V) at a frequency of 60 Hz. However, the country has two types of voltage: single-phase (120 volts phase-neutral and 240 volts phase-phase) and three-phase (127 volts phase-neutral and 220 volts phase-phase). It is important to use power converters when connecting devices to a different voltage or frequency to avoid damage or electrical fires.

The standard light voltage is 127 volts
In Mexico, the standard light voltage for most homes and businesses is 127 volts (V) at a frequency of 60 Hertz (Hz). This is slightly higher than the voltage found in some other countries, which is typically around 120 V.
There are two types of voltage in Mexico: single-phase and three-phase. Single-phase voltage is either 120 volts phase-neutral or 240 volts phase-to-phase. Three-phase voltage is typically 127 volts phase-neutral and 220 volts phase-to-phase. However, there are some variations in three-phase voltage, which can also be 110 volt phase-neutral and 190 volt phase-phase, 115 volts phase-neutral and 220 volts phase-phase, or 120 volt phase-neutral and 208 volt phase-phase.
The standard light voltage of 127 volts in Mexico falls within the range of voltages typically found in North America, which is 120 +/- 10% or 240 +/- 10%. This means that appliances designed for use in North America will generally operate safely within the 127-volt electrical system in Mexico.
The frequency of 60 Hz in Mexico is also commonly found in the Americas and parts of Asia, while other parts of the world typically use 50 Hz. The choice of frequency was historically influenced by colonial and industrial influences, with European countries spreading the use of 50 Hz to their colonies, while the US and its allies adopted 60 Hz. Mexico, which had previously operated with both 50 Hz and 60 Hz standards in different regions, unified under the 60 Hz standard in the 1970s.
It is important to note that electrical devices may require a power converter if they are not compatible with the standard light voltage and frequency in Mexico.

There are two types of voltage
In Mexico, the electrical source is 60 Hz. This is the number of cycles per second in an alternating current (AC). There are two types of voltage: DC voltage and AC voltage.
DC voltage, or direct current voltage, always has the same polarity (positive or negative). It is commonly produced by sources of stored energy, such as batteries. Sources of DC voltage have positive and negative terminals. DC voltage is typically used for electronics.
AC voltage, or alternating current voltage, alternates between positive and negative polarity. In the US, AC voltage from the wall socket changes polarity 60 times per second, while in the UK and Europe, it changes polarity 50 times per second. AC voltage is typically used for motors.
The choice between DC and AC voltage depends on the nature of the intended load. AC voltage is more common, as utilities deliver it to homes and businesses, and most devices use AC voltage. However, some household devices, such as TVs and computers, use DC voltage power. These devices use rectifiers to convert AC voltage and current to DC.
The voltage between two points is independent of the path taken to get from one point to the other. It is always measured between two points, and one of them is often the "ground" or zero-volt point. Voltage is what makes electric charges move, and it is measured in volts. The volt is named in memory of Alessandro Volta, and one volt equals one joule per coulomb.

The Federal Electricity Commission supplies the AC voltage
Mexico's electricity sector is managed by the Federal Electricity Commission (CFE), or Comisión Federal de Electricidad in Spanish. The CFE is a state-owned entity that was given priority in selling electricity to Mexico's national power grid in the 2021 reform of the Electricity Industry Law (LIE).
The CFE supplies electricity at a frequency of 60 Hz, which is the standard in the Americas and some parts of Asia. The choice of frequency is rooted in the country's colonial and industrial history. In the late 19th century, American engineers at Westinghouse championed 60 Hz as it allowed for smaller and lighter transformers, reducing costs for sprawling power grids. This also synced well with the 60-second clock, simplifying electrical calculations.
Mexico's adoption of the 60 Hz standard can be traced back to the influence of the United States, its northern neighbour and ally. In the 1970s, areas of Mexico that previously operated on a 50 Hz grid were converted to 60 Hz, unifying the country under a single standard.
The voltage supplied by the CFE varies depending on the specific region and application. In North America, including Mexico, a unique split-phase system is used to supply most premises. This system concurrently provides both 240 volts and 120 volts, allowing homeowners to wire up circuits according to their needs and local building codes. Typically, smaller appliances and electronic devices use 120 V sockets, while larger appliances like dryers, electric ovens, ranges, and EV chargers require dedicated 240 V sockets.
The CFE's role in supplying AC voltage has been a subject of debate in Mexico's energy sector. In 2023, the Supreme Court ruled that a law prioritizing the CFE over private companies in selling electricity to the national grid was unconstitutional, citing principles of free competition in the power sector.

Power spikes and surges are common
When electricity returns after a power cut, spikes and surges may occur, and the voltage can be higher than normal, posing a risk to computers and other sensitive equipment. To address this issue, residents can invest in power surge protectors, voltage regulators, or uninterruptible power source (UPS) devices. UPS systems are batteries in a box that charge when the power is on and keep devices running during outages.
The voltage in Mexico is set to 127V and 60Hz, which is similar to the US (120V). However, Mexico's electricity supply differs from that of Europe and other regions with 220V-240V standards, requiring voltage converters for appliances from these regions. The 60Hz frequency in Mexico is a legacy of US influence, as American engineers favoured this standard due to its compatibility with their power grids and clocks.
To summarise, power spikes and surges are common in Mexico due to infrastructure challenges and weather events. Residents can protect their equipment by investing in surge protectors, voltage regulators, or UPS devices, particularly if they work from home or have sensitive equipment.
