Quartux is a Mexican energy technology company that designs, installs and operates battery energy storage systems (BESS) for industrial businesses, commercial properties and electricity generators. The installations use lithium-ion batteries and Quartux Control, proprietary software that manages charging, discharging and electricity consumption. The systems help large electricity users reduce peak demand, store power for later use and manage expenses under time-based electricity tariffs. Customers include businesses in automotive manufacturing, metallurgy, steel, food processing, textiles, plastics, aerospace and hospitality, where electricity costs and interruptions can affect production schedules and operating expenses.

Battery energy storage systems store electricity and release it when required. A factory can charge its batteries during lower-cost periods and discharge them when grid electricity becomes more expensive or facility demand increases. Businesses with onsite solar generation can store surplus electricity for use after solar production declines. Depending on the electrical configuration, batteries can also provide backup power to designated equipment during grid interruptions. Quartux offers direct purchases, leasing, and a battery-storage service arrangement, giving customers alternatives to financing the full installation upfront. Published operating figures include more than 100 operational sites, over 10 million operating hours and more than 50 gigawatt-hours dispatched. These are company-reported figures, not independently verified performance results.

Software Manages Electricity

Quartux Control monitors electricity consumption and coordinates battery charging and discharging. The energy management system uses consumption data and electricity tariffs to schedule battery use, helping businesses reduce grid purchases during expensive demand periods. Peak shaving occurs when batteries discharge as a facility approaches a costly demand peak, reducing the maximum power drawn from the grid during that interval. Energy arbitrage offers another potential source of savings: a system stores electricity when prices are lower and uses it when grid electricity costs more. Actual savings depend on tariff rules, consumption patterns, battery efficiency, installation expenses, and maintenance costs

The software also monitors electrical parameters and battery performance, allowing operators to track energy use and equipment status. Quartux systems can be integrated with existing electrical infrastructure and used alongside onsite solar installations. Remote monitoring and technical service help operators identify equipment faults and manage system performance. Backup duration depends on battery capacity, the amount of electricity being consumed and the loads connected to the system. Batteries also lose some stored energy during charging and discharging, while repeated cycling affects their usable life. Customers evaluating an installation need to consider verified electricity-bill reductions, equipment availability, maintenance expenses and the amount of energy delivered over the battery’s service life.

Capacity Expansion Plans

In March 2026, Quartux tripled its installed battery-storage capacity in Mexico and plans to exceed 1,000 megawatt-hours by year-end. More than 300 MWh of capacity was installed across commercial and industrial projects at the time. The expansion plan included a new generation of lithium-ion battery systems integrated with Quartux Control. Proposed deployments included areas such as Cancún, the State of Mexico and Guadalajara, where commercial and industrial facilities require substantial amounts of electricity. The 1,000-MWh figure is a year-end target, not confirmation that the capacity has already been installed.

Mexico also introduced new regulations for battery energy storage in 2026. On April 16, the National Energy Commission published provisions governing the integration of electricity storage systems into the National Electric System. The rules establish requirements for connecting and operating storage installations, define participation arrangements, and address services that batteries can provide. They also cover storage associated with power plants, industrial and commercial consumption sites, self-consumption projects, transmission and distribution infrastructure, and standalone installations. The provisions replaced earlier storage rules issued in March 2025. Quartux’s planned expansion will require completed installations, equipment commissioning and compliance with the technical and administrative requirements applicable to individual projects.

Financing and Customer Economics

Quartux offers direct purchases, leasing and BESS-as-a-Service for customers with different financing requirements. A direct purchase requires an upfront payment for equipment and installation. Leasing spreads payments over an agreed period, while the service option uses a shared-savings agreement without requiring the customer to finance the battery infrastructure upfront. These arrangements let industrial operators compare the cost of purchasing and maintaining a system with the expected savings from lower electricity bills. The financial results depend on each facility’s tariff, demand profile, operating hours, battery capacity and contract terms. Advertised returns and payback periods must therefore be evaluated against actual consumption data, installation expenses and financing costs.

Battery storage can help Mexican businesses manage electricity expenses, use onsite renewable generation and maintain power for designated loads during grid interruptions. It does not generate electricity, and the financial value of an installation depends on how much energy can be stored and delivered, how frequently the batteries cycle, and the difference between charging costs and the value of the electricity later used. Backup capability also depends on system design and the amount of energy available when an interruption occurs. For large customers, the investment decision rests on measurable bill savings, equipment reliability, maintenance requirements and financing costs. Quartux’s target of more than 1,000 MWh by the end of 2026 provides a measurable benchmark for its expansion. Confirmed installations and operating results will establish whether the company reaches that target and how much additional storage capacity enters service.
