An international group with cogeneration and BESS plants operating worldwide · Mexican engineering since 1987
ENEGRIN is the energy company of the Córdova industrial group and part of an international group of technology partners. We design, finance, install and operate battery energy storage systems (BESS) and on-site gas power plants, with savings measured on the bill from CFE, Mexico’s state-owned utility.
Measured savings of 27–37 %
on CFE bills with ENEGRIN BESS in actual operation, depending on season and consumption
No upfront investment
under the shared-savings model: the system pays for itself out of the savings
Plant 100 % backed up during outages
with automatic transfer, within a 2-hour autonomy at maximum discharge (optional)
Transparency guarantee
| No. | Figure | What it proves | How it is verified |
|---|---|---|---|
| 01 | 99.98 % | Match between the CFE bill we forecast and the bill that arrived. It proves we calculate your bill exactly as CFE does. | Reconciliation published every month |
| 02 | 27–37 % | Savings measured on CFE bills with ENEGRIN BESS in actual operation, depending on season and consumption. Not a projection: the range of every reconciled month. | Two meters + CFE formulas and tariffs · reproducible by any auditor |
| 03 | 2 meters | Per system: one in parallel with CFE's meter and one on the BESS side. Together they yield the month's actual savings, without inflating them. | Readings available to your auditor on request |
| 04 | 150+ MWh | Energy dispatched by the systems ENEGRIN operates, cumulative through the last reconciled month. | Updated every month with the reconciliation |
| 05 | 300+ MW | And 600+ MWh of BESS installed in 13 countries and regions by the international group of technology partners we belong to, with the same hardware we install in Mexico. | Group project portfolio · plant visits on request |
The site rebuilds your current bill and shows you the same bill with BESS. If the number is of interest, request a formal proposal in one click.
Our engineering team sizes the system from your bills and delivers a proposal with both payment models. No upfront investment, if you choose.
An integrated system, with permits and filings included. Our EMS operates the system according to CFE's tariff rules; our engineers supervise it with continuous remote monitoring.
One, in parallel with CFE's meter, replicates its measurement exactly; the other, on the BESS side, measures what we deliver to you. We apply the CFE formulas and tariffs for your region to both. That is how we calculate actual savings, without inflating them.
Two business lines, the same engineering
BESS · energy storage
For plants on CFE's GDMTH, DIST or DIT tariffs, or on qualified supply: measured savings of 27–37 % on the bill, a better power factor and, with optional backup, continuous power when CFE's supply fails. If it makes sense for your plant, the same system integrates solar generation, sized from your bills and operated by the same EMS.
Cogeneration and gas-fired generation · over 1 MW
Cummins natural gas engines with an integrated BESS so they run close to maximum efficiency, with power quality guaranteed by contract. If we put the engines' heat to use in your process, as steam, hot water or absorption cooling, it is cogeneration; if not, it is on-site gas generation for self-consumption, under the same model. ENEGRIN finances or builds the plant; you pay for the energy delivered, below what you pay today.
How you pay
ENEGRIN installs, operates and maintains the system. Each month, the savings on your bill cover the service and you keep a share. Guaranteed: you never pay more than you would have paid CFE without the system. You can buy the system later.
You buy the system at the outset or later on. All the savings stay with your plant, and ENEGRIN continues to operate, monitor and maintain it.
What we guarantee
You never pay more than you would have paid CFE without the system. It is written into the contract.
Two meters, CFE's formulas and a reconciliation published every month. Any auditor can reproduce the calculation.
The simulator and the proposal give you the number you should then see on your bill. If the system doesn't make sense for you, we tell you before asking you for anything.
We develop Ollin, the EMS and platform that operate your system, in-house, using artificial intelligence built for Mexico's tariff rules. The hardware is Siemens, Cummins and Tier 1 cells, depending on the system; the brain is Mexican.
Mexico, 2026
The grid will not grow at the pace of your plant, and every outage or voltage fluctuation costs production and equipment. The law now permits the alternative. ENEGRIN designs, finances and operates it: your own stable, high-quality power, measured with CFE’s formulas. Under the shared-savings model, the client does not invest.
