The latest tender launched in Mexico, awarding 3.3 GW of renewable energy and 1.2 GW of battery storage to private developers, represents a watershed moment for the country’s energy storage market. For Quartux, the process not only unlocks new market opportunities but also strengthens its financial position to expand into the utility-scale segment.
“This tender is a major opportunity for the entire country. Names such as Iberdrola, Gemex and Copenhagen Infrastructure Partners are already being discussed. These are players involved in strategic projects that require around 30% storage, and we are ready to support them,” said Diego Rasilla González, Chief Revenue Officer at Quartux, speaking to Energía Estratégica. The awarded projects are expected to enter operation between 2028 and 2029.
Against this backdrop, Quartux forecasts a storage boom in Mexico, beginning to take shape from the second half of this year through the first half of 2027.
“The first six months of 2026 will be critical to kick off detailed engineering. Construction and commissioning of the systems will follow shortly afterwards,” Rasilla anticipated.
At present, Quartux holds 85% of the national market share in the commercial and industrial (C&I) energy storage segment, with more than 300 MWh installed and operational. The company is now seeking to move decisively into utility-scale storage, aligning itself with the broader growth of Mexico’s power sector.
With an investment capacity exceeding USD 1 billion, Quartux says it faces no financial constraints. “Today, we have no limitations. We can invest and complement not only private companies but also the state-owned utility,” Rasilla noted, referring to Comisión Federal de Electricidad (CFE).
He added that Quartux’s strong battery procurement capacity allows it to secure more competitive pricing and maintain control over logistics. Battery prices have fallen by around 15% over the past year, a trend the company expects to continue thanks to the scale of its project pipeline.
Regulation remains a critical challenge. Rasilla stressed the importance of the private sector sharing operational experience with regulators to improve market design, particularly regarding the lack of economic recognition for the grid-support services provided by energy storage systems.
“This flexibility must be compensated for both private investors and the electricity grids operated by CFE. In regions such as the Yucatán Peninsula, storage can stabilise the system and step in during outages, and that value needs to be recognised,” he underlined.
International comparisons are inevitable. Texas has already installed more than 6 GWh of battery storage, while California has more than triple that volume. In South America, Chile has moved ahead rapidly, supported by a clear regulatory framework that sends strong signals to investors.
Technology as the engine of scale and long-term growth
At the core of Quartux’s operations lies its artificial intelligence-based software platform, developed in Mexico and already exceeding one million operating hours. The system learns in real time from customer consumption patterns, grid behaviour and electricity demand.
“This platform will eventually be able to predict critical hours and anticipate grid failures. It is so advanced that it will become a leading tool for the sector,” Rasilla said.
On the financial side, Quartux recently closed a USD 50 million strategic investment with Ainda Energía e Infraestructura, aimed at strengthening its participation in large-scale projects, including those emerging from the new wave of renewable generation awarded under the latest tender.
Looking ahead, Quartux is pursuing sustained growth in the short and medium term. The company has expanded its workforce from 10 to more than 140 employees in just a few years and plans to double both headcount and investment annually. After investing USD 500 million in 2023, Quartux targets USD 1 billion by 2026 and USD 2 billion by 2027.
“Our goal is not only to lead the storage market, but to become a trusted player in Mexico’s energy sector—and eventually across Latin America,” Rasilla concluded.
