CLIENTS

For forward-thinking companies driving energy transformation.

Our solutions are designed for companies with high energy demand and complex infrastructure systems—where decisions have the greatest impact on cost, reliability, and sustainability.

Our clients:


Large energy-intense companies and industries – steel, chemical, paper, glass, metal processing, and pharmaceutical manufacturing.

Medium-sized and niche companies with energy-demanding processes – specialized chemical treatment, plastics processing, glassmaking, food industry, recycling, and waste management.

Industrial complexes and business zones – where optimization of energy systems, long-term resilience, and strategic investment are essential.

Our clients look for:

reliability and transparency in decision-making,

cost optimization through sustainable solutions,

a partner who understands the entire system—both technical and financial.

Our approach is tailored for companies in search of a trusted expert partner who combines engineering precision with financial clarity.

IN PRACTICE

Real challenges. Real solutions.

Every decision carries risks and opportunities. Our cases show how we manage them.

Case:
Energy System upgrade

The Challenge
A company plans to replace part of its energy system (cooling, compressors, boilers …) with more efficient or greener technology, depending on its strategy.

The Typical Pitfall
Such replacements are often approached too narrowly:

  • Should the old system be written off or kept as backup?
  • How will integration of the new equipment affect other departments (HSE, production, logistics …)?
  • ROI calculations often overlook hidden costs—backup, integration, and operating expenses.

The Antaren Approach
Instead of a partial perspective, we deliver a comprehensive technical and financial assessment of all alternatives:

  • Transparent view of the total cost impact 
  • Evaluation of the effect on production costs and long-term competitiveness.
  • Technical scenarios presented with both risks and benefits—so management decides with a clear view of the whole system.

Our approach means fewer surprises and greater transparency, leading to decisions that are both sustainable and feasible in the long run.

Case:
Energy Audits

The Challenge
Companies are required to conduct regular energy audits, which typically result in a list of proposed optimization projects.

The Typical Pitfall
These lists are often too superficial:

  • projects are only briefly described,
  • payback times are estimated roughly,
  • the report usually ends up in a drawer because investors cannot determine what is truly worth pursuing.

The Antaren Approach
We turn an energy audit into a strategic decision-making tool:

  • Detailed analysis of both the financial and energy impact of proposed solutions on the entire company.
  • Preparation of a strategic implementation plan and proposals for additional measures.
  • Project development taken to the level where they can be included in budget plans, obtain financing, and be handed over to project designers.

With our approach, an energy audit is no longer just a formal document—it becomes a springboard for concrete decisions and actionable projects.

Case:
Establishing Advanced Energy Management

Challenge
Companies aim to implement efficient energy management – either in new facilities or in existing operations, where they seek better control over consumption and performance indicators.

Typical Pitfalls

  • In new facilities, key parameters are often not included early enough in the project design phase.
  • In existing systems, companies often don’t know where to start or lack internal resources.
  • The result is insufficient measurement, scattered data, and systems that fail to deliver meaningful insights for decision-makers.

Antaren’s Approach
We establish energy management as a comprehensive, strategic process:

  • For new facilities, we define key indicators at the right time. For existing operations, we conduct a detailed assessment of the current situation.
  • We develop an environment for regular monitoring systems, reporting, and key performance indicators that enable concrete improvement proposals.
  • We prepare recommendations for smart recapex and project documentation.

→ The company gains a living energy management process that drives cost optimization, better decision-making, and sustainable competitiveness.
