Lower energy cost per tonne at your mine in Mexico

ASHRAE Level II and III energy audits and ISO 50001 readiness for mining and metals operations facing CFE demand charges, remote grid constraints and outage risk. We measure what your equipment actually draws, then hand your board a fact base it can act on. We sell no equipment and take no commissions.

Energy is the largest controllable cost per tonne, and most of it sits in six systems

Electricity and fuel run 15% to 40% of total production cost in mining and metals, depending on process and ore body. The CFE bill shows the total. It does not show which mill start set the billed demand or what each system costs per tonne processed. The audit measures those systems on site, coordinated with your operations team and using your existing metering.

Crushing and grinding circuits

Energy intensity benchmarking of comminution, motor loading and throughput to energy ratios for SAG and ball mills.

kWh per tonne · motor load · throughput

Pumping and dewatering

Pump efficiency testing, system curve analysis and variable speed drive assessment for process and dewatering circuits.

Ventilation

Ventilation on demand assessment, fan curve analysis and airflow management for underground and process areas.

airflow · fan curve · schedule

Load curves and peak events

Interval metering analysis, demand profiling and identification of the equipment sequences that set the billed peak.

Auxiliary utilities

Compressed air, HVAC and lighting reviewed for efficiency and load reduction across the plant and camp.

CFE tariff and billing

Every audit also reviews rate structure, power factor correction, demand ratchets and tariff migration options, so the measured findings connect directly to the line items on the bill.

Operators and owners read the same audit

Whether you run the plant or own the asset, energy is the cost that swings your margin per tonne and the risk that can stop production. The audit is written so the site team can act on it and the investment committee can rely on it.

Producers and site leadership

Lower and stabilize energy cost per tonne across crushing, grinding, pumping and processing. Cut demand charge spikes and firm up reliability on constrained grids.

Private equity owners

Improve EBITDA and lower asset risk with an audited energy cost baseline you can verify at exit.

Institutions and lenders

Document the energy risk in your holdings to a standard your investment committee will accept.

When demand spikes and the grid is weak, production is on the line

A single uncoordinated peak can reset your billed demand for a full cycle. Remote sites run on constrained grid connections where one outage stops throughput. The audit finds the events and the equipment behind them, then maps where your supply is exposed before it costs you a shift.

Your energy cost per tonne, before and after measures

Enter your annual energy spend and annual throughput. The calculator shows your current energy cost per tonne and what a 10% and a 20% reduction would be worth. The preliminary review replaces this scenario with your own measured baseline.

Annual energy spend (USD millions)

12 M

Electricity and fuel across the site, including demand, transmission and power factor charges.

Annual throughput (thousand tonnes)

2,500 kt

Ore processed or metal produced, whichever your cost reporting uses.

Reference

In the representative engagement above, the modeled cost per tonne moved from USD 5.40 to USD 3.40 after measures, a 37% identified pathway. The 10% and 20% cases shown here are illustrative reduction levels, not a forecast for your site.

Every project risk has a control defined before work starts

Project risks and MEP controls
Risk	Control
Confidential site data	A mutual NDA is executed before bills, interval data or production records are shared. MEP never discloses client names without written consent.
Production interruption	Measurement is non-invasive, uses existing metering and is scheduled with operations around shutdowns. The preliminary review requires no site visit.
Remote site logistics	The site work plan sets access, safety induction, measurement points and windows before the field team travels.
Vendor bias	MEP sells no equipment, takes no commissions and does not act as installer. Recommendations rest on measured data and your site's economics.
Unsupported savings	Every investment case keeps assumptions, dependencies, missing data and measurement requirements visible, with an IPMVP-aligned M&V plan.

What mine managers, CFOs and asset owners ask

What do you need for the preliminary review?

One recent CFE bill per site or twelve months of monthly consumption, the site location and the process stages in operation. No site visit and no contact with suppliers at this stage.

Will the measurement interrupt production?

No. Field measurement is non-invasive, uses your existing metering where available and is scheduled with the operations team around planned windows. The site work plan is agreed before anyone travels.

Our site is remote and the grid is weak

That is the profile most of our mining work covers. The supply reliability review maps interconnection, power quality, backup adequacy and contingency protocols, and the team has delivered at remote sites in Sonora, Chihuahua, Durango, Zacatecas and Guerrero.

How is MEP paid?

Through fees paid by the client. MEP receives no commissions from suppliers, generators or equipment manufacturers, so the recommendation does not depend on which vendor wins.

Can the report go to our investment committee as is?

Yes. The executive summary, financial model and M&V plan are written to the standard finance teams, investment committees and lenders expect, and the deliverables are built to survive diligence.
