Mexico Must Prioritize Energy Storage for Infrastructure Security

Mexico’s energy debate often focuses on generation, pipelines, and refining capacity, but storage is what turns infrastructure into security. Whether in electricity, natural gas, or liquid fuels, storage provides the resilience needed to absorb shocks and maintain continuity. Mexico has made progress in all three areas, but advances remain uneven and still fall short of the country’s risk profile. If Mexico wants a more reliable, competitive and sovereign energy system, storage must become a national priority.

Electricity Storage

Mexico has finally created a clearer framework for electricity storage, recognizing standalone systems, paired projects, and other configurations within the National Electric System. This gives storage stronger legal standing and greater certainty, which is a major improvement over years of some regulatory ambiguity.

Mexico also deserves credit for treating storage as a system asset, not just a renewable add-on. In a grid with planned growth in solar and wind penetration, storage should be valued for flexibility, backup, and efficiency.

What remains missing is investable market design: clearer revenue streams, particularly on capacity, bankable dispatch rules, operational certainty, and transparent planning treatment. Without this, Mexico risks having the framework but not the projects needed at the scale and in the location to maximize system wide benefits.

Natural Gas 

In natural gas, Mexico correctly identified the problem years ago: a power sector and industrial base that rely heavily on imported gas cannot depend on pipelines alone. The 2018 storage policy accurately diagnosed the country's vulnerability.

But execution has lagged. Mexico remains exposed to weather events, infrastructure constraints, and supply shocks. Strategic storage is still more a plan than a real shield against disruption.

The main gap is institutional and commercial. Mexico still needs a credible model that defines who procures strategic storage, who pays for it, when inventories are released and how strategic and commercial storage interact.

Liquid Fuel Storage

Mexico has been most explicit on liquid fuel storage. Minimum inventory obligations for gasoline, diesel, and jet fuel were the right policy choice because an open fuel market without storage requirements is inherently vulnerable.

There have also been real infrastructure gains through the expansion and rehabilitation of terminals by both public and private participants, improving resilience against logistical bottlenecks and regional imbalances.

Still, compliance and regional depth remain uneven. Mexico continues to operate with thinner storage margins than a country of its size and exposure should accept, which makes stronger enforcement and better transparency essential.

What Mexico Should Do Next

Mexico should now adopt a unified storage agenda across electricity, natural gas, and liquid fuels. In electricity, the priority is moving from framework to implementation with transparent rules that let storage monetize its services. In natural gas, the goal should be to turn strategic storage into an executable infrastructure program with assigned responsibilities and financing. In liquid fuels, the next step is stronger compliance verification and continued expansion in underserved regions.

A serious storage policy should be technology-neutral where appropriate, regionally differentiated, and coordinated across agencies. Mexico has already taken meaningful steps, but the decisive phase is execution. In energy policy, resilience is not declared; it is built before the crisis arrives.
