How to reduce diesel costs in mining: The Solution Nomad is presenting at EXPONOR Chile

Nomad Solar Energy

Fuel Price Volatility Is Impacting Mining OPEX in Chile and Ecuador. Nomad offers an alternative that helps reduce costs and improve operational predictability on site.

The cost of diesel has become one of the main concerns for the mining industry in Latin America. In both Chile and Ecuador, the gradual removal of subsidies and increased exposure to international oil prices are putting growing pressure on operating costs.

But the issue is no longer just how much fuel costs today. What’s even more critical: is the difficulty of predicting how much it will cost tomorrow.

Why is diesel becoming increasingly critical for mining in Ecuador?

In Ecuador, the recent process of reducing fuel subsidies has led to a significant increase in diesel prices. This directly impacts:

• Mine haulage and internal transportation
• Heavy machinery and equipment
• Power generation in remote locations
• Supply chain and logistics operations

The outcome is clear: diesel has shifted from being a stable cost component to an uncertain variable within mining OPEX. For many operations, this means:

• Greater difficulty in budgeting and forecasting
• Increased pressure on profit margins
• Higher operational risk

The real issue is not the price it’s predictability

This is where the key paradigm shift lies.

Reducing costs remains important, but in today’s environment, the primary challenge is regaining control over energy costs.

When diesel prices fluctuate constantly:

• Financial planning becomes less accurate
• Cost per tonne becomes less predictable
• Decision making tends to become more conservative

How can mining operations reduce their dependence on diesel?

This is the question many mining operators are asking today.

The answer does not necessarily require replacing the entire energy system. Instead, it lies in a more pragmatic approach: reducing diesel consumption at specific points across the operation.

That is where Nomad’s solution comes in.

Nomad’s solution: mobile solar energy for mining

At EXPONOR Chile, Nomad Solar Energy will showcase a solution designed to reduce mining operations’ exposure to diesel by integrating mobile solar power systems.

The approach is straightforward:

• Direct deployment in the field
• No permanent infrastructure required
• Seamless integration with existing operations

This enables mining companies to replace a portion of their fuel consumption with an energy source that offers greater cost predictability.

Direct economic benefits for mining operations

Reduced energy costs

Lower diesel consumption across auxiliary systems and specific operational processes.

Reduced OPEX volatility

The introduction of a stable energy source into the overall energy mix helps mitigate exposure to fuel price fluctuations.

Improved financial planning

Greater visibility and predictability of energy-related expenditures enable more accurate budgeting and forecasting.

Reduced operational risk

Less reliance on fuel supply logistics helps improve operational resilience and business continuity.

Greater operational flexibility

Adaptable solutions that can support different stages of a mining project’s lifecycle, from exploration and construction to active operations.

A different approach: optimize, don’t replace

Unlike other energy solutions, Nomad does not aim to fully electrify mining operations.

Instead, its approach is more practical and immediately applicable: targeting the areas where diesel creates the greatest costs, risks, or inefficiencies. This simplifies implementation while reducing both technical and operational barriers.

Why is this particularly relevant for mining in Ecuador?

Although Nomad is showcasing its solution in Chile, the context in Ecuador is arguably even more sensitive due to:

• Recent increases in diesel prices
• Uncertainty surrounding future energy policies
• Heavy reliance on fuel for remote mining operations

As a result, managing energy costs is becoming a strategic priority for mining companies across the country.

EXPONOR Chile: an opportunity to explore practical solutions

Nomad will be exhibiting at EXPONOR Chile, where the company will demonstrate how its solution can be integrated into existing mining operations.

For mining operators and companies in Ecuador, the event provides an opportunity to:

• Explore alternatives to diesel dependency
• Understand new approaches to energy cost control
• Evaluate solutions that can be implemented within their own operations

The mining industry is entering a new phase in which energy is no longer a secondary operating cost but a strategic variable. The challenge is no longer simply reducing costs it is gaining greater control over them.

Solutions such as Nomad’s are designed to transform a portion of energy expenditure into a predictable, manageable, and optimizable cost.

If you are evaluating ways to reduce diesel dependence in your mining operation, EXPONOR Chile is the ideal place to start.
