Under which legal figure does this operate?

Mexico's current electricity framework contemplates three self-supply modalities: isolated, interconnected with surplus sales, and interconnected without surplus sales. Each project is structured under the modality that optimizes permits, timelines and economics. Gemex manages the full regulatory process: generation permits, interconnection where applicable and ongoing compliance.

Who finances and who operates the plant?

Gemex develops, finances, builds and operates. Your company does not invest capital in the asset: you consume energy under a long-term contract with agreed conditions. Operation and maintenance are ours for the life of the contract, with committed availability.

What if gas prices rise?

The contract structure defines how fuel risk is shared: there are schemes with transparent indexed pricing and schemes with hedging. What disappears is the exposure to regulated supply tariff adjustments and transmission costs, which are the components that have historically risen the most. In the technical-economic proposal we model the scenarios with your numbers.

When does gas win and when does solar win?

They are complementary, not rivals. On-site gas produces 24/7 with a high capacity factor on a small footprint, delivers useful heat if your process uses it, and sustains critical loads that admit no intermittency: for a data center or a continuous process it is the firm base. Solar with batteries turns surface into low-cost renewable energy, covers daytime profiles and shifts peaks with storage. We develop both lines as a standalone solution, under the same zero capex model, and the assessment tells you which one wins with your numbers.

How long does a project take?

The assessment takes weeks, not months. From signing, a typical 3–20 MW project reaches operation in 12 to 24 months, depending on modality, interconnection and the site's gas access. The detailed schedule is part of the proposal.

Does my site have natural gas access?

Mexico has a robust trunk network (SISTRANGAS and private pipelines such as Los Ramones, Wahalajara or Mayakan) plus virtual LNG/CNG options where the pipeline does not reach. Supply viability is among the first things we verify in the assessment, at no cost.

What happens to my current supply contract?

Self-supply coexists with your current supply: it can cover the base load and leave the grid as backup, or cover everything under the isolated modality. The transition is designed so your operation is never exposed.

What about emissions?

Efficient generation with natural gas, and especially cogeneration at over 80% combined efficiency, reduces primary energy consumption versus consuming grid electricity and generating heat in separate boilers. We do not dress it up: it is natural gas, and what it offers is measurable, reportable efficiency for your sustainability commitments.

We develop tailor-made projects from 3 to 20 MW. We are not small-scale distributed generation: we design, finance and operate power plants for critical loads.

Three generation lines

Three lines. The same deal.

Firm gas power, cogeneration and solar with batteries: three expert lines under the same model. GEMEX puts up 100% of the capital and you consume your energy under a 15 to 20 year contract. Zero capex, one single counterpart.

Data centers

A data center does not negotiate availability: every minute without power is an SLA breach. We design dedicated generation plants with N+1 or 2N architectures, aligned to the Uptime Institute's Tier III (99.982%) and Tier IV (99.995%) availability requirements, as primary source or in a hybrid scheme with the grid.

On-site generation with natural gas delivers the firm, continuous, high-quality power a critical compute load demands, without depending on available interconnection capacity in the area, today the number one bottleneck for new data centers in Mexico.

Firm behind-the-meter power: your project timeline stops depending on the interconnection queue.

Industrial parks

A centralized plant inside the park, with distribution to multiple facilities and per-tenant metering. The park offers reliable, competitive power as a strategic amenity: the differentiator that decides where advanced manufacturing tenants set up today.

The model applies to new parks (designed from the master plan) and operating parks (integration with existing infrastructure). Gemex develops, finances, builds and operates; the park and its tenants consume under a long-term contract.

The park that guarantees power wins the tenants others cannot receive.

The three modalities the law contemplates

All three modalities apply to all three lines: gas, cogeneration and solar with batteries. The technical assessment defines the right one for your project.

Isolated self-supply

Your plant generates behind the meter, with no grid interconnection. Maximum independence and the most direct permitting path.

Interconnected with surplus sales

You generate for your own consumption and sell surplus energy to the system. Optimizes project sizing.

Interconnected without surplus sales

Interconnection as backup, without injecting energy into the grid. Operational flexibility with simpler permitting.

The group solution

One accountable party: from the pipeline to your power

The project does not end at the plant: gas has to arrive, with permits, right of way and firm supply. Gemex Autoconsumo solves it end to end with the group's companies.
