⦿ MISSION AND VISION

Build the energy infrastructure of the future.

AESYS — Applied Energy Systems d.o.o. was founded on the belief that the Balkans’ energy transition is about more than solar power plants and wind farms. For renewable energy to become reliable and efficient, energy storage is essential.

That’s why we develop BESS solutions that support a more decentralised, resilient, and efficient energy system — giving businesses greater control over their energy consumption, reliability, and costs.

⦿ Energy Future

The Energy Transition.

The growth of renewable energy, grid instability, and volatile electricity prices demand a new approach — one where energy storage becomes a cornerstone of modern energy infrastructure.

We believe battery energy storage systems will become standard alongside every major solar power plant, wind farm, and industrial facility across the region. Those who build flexibility into their energy strategy today will gain greater control, resilience, and competitive advantage tomorrow.

⦿ How we deliver BESS solutions

Complete support throughout the entire BESS lifecycle.

Our ambition is to become a leading energy storage company in Southeast Europe.

We don’t simply supply equipment. We design, integrate, and maintain energy storage systems that form the foundation of tomorrow’s energy infrastructure.

  • System Design

    We analyze energy consumption, load profiles, and usage patterns to design a BESS tailored to the customer’s actual needs. Every solution is sized around the required capacity, operating strategy, and long-term objectives of the project.

  • Integration

    We integrate the BESS with your existing electrical infrastructure, EMS platforms, and renewable energy sources. Our goal is stable system operation, maximum energy utilization, and simple, effective control.

  • Maintenance

    We provide continuous monitoring, technical support, and preventive maintenance throughout the entire system lifecycle. Through fast response and ongoing optimization, we help ensure system reliability, stability, and long-term performance.

⦿ Our Values

Why AESYS?

Five principles that define who we are:

  • 1

    Technical Excellence

    Energy systems operate 24/7 — and every failure has real consequences. That’s why every technical claim we make is backed by data, specifications, or a clear explanation.

  • 2

    Integrity

    Transparency with our clients, financing partners, and regulators is the foundation of relationships built to last.

  • 3

    Partner Centric

    We don’t focus on transactions. We build lasting relationships. The system we install today is one we intend to support and maintain for years to come.

  • 4

    Innovation with Purpose

    We adopt new technologies when they deliver measurable value — not simply because they are the latest trend.

  • 5

    Responsibility

    Every system we deploy contributes to a more resilient grid and a cleaner, more efficient energy future across the region.

Energy Projects Don’t Fail Because of Technology — They Fail Because of Poor Coordination.

Between equipment suppliers, contractors, financing institutions, and legal advisors, coordination can quickly become complex. Communication gaps happen. Mistakes happen.

That’s why we bring technical, legal, and financial expertise together under one roof.

For you, that means one trusted partner, one contract, and one point of responsibility — from the initial analysis through commissioning and long-term system maintenance.

⦿ Expertise

Areas of expertise.

  • BESS system design

    System sizing based on energy consumption, load profiles, and the project’s energy objectives.

  • EMS platform integration

    Integrating BESS with existing electrical infrastructure and energy management platforms.

  • Energy optimization

    Reducing peak demand and optimizing grid-related and fixed energy costs.

  • Peak shaving & backup systems

    Greater system resilience and more reliable energy management during critical operating scenarios.

  • Container & Cabinet ESS solutions

    Scalable energy storage systems for a wide range of industrial and infrastructure applications.

  • Support and maintenance

    Continuous monitoring, technical support, and performance optimization throughout the system lifecycle.

⦿ A Real Need, Not a Future One

The energy sector is changing fast.

Rising energy prices, grid instability, and the rapid integration of renewable energy are changing how businesses manage and use electricity.

BESS systems are becoming a critical part of modern energy infrastructure, enabling:

✓ Reduced peak demand

✓ Greater grid stability

✓ More efficient use of renewable energy

✓ Lower and more predictable energy costs

"Every system is designed around the customer’s actual energy needs, existing infrastructure, and long-term project objectives."
