BESS, explained the way it actually gets built — watch the preview.

What the instructor says, word for word.

The energy industry is going through the biggest transformation in its history — and most engineers are learning it while already building real projects. Battery energy storage systems are no longer optional. They are essential. They stabilize grids, enable renewables, and keep the lights on.

But here's reality: this industry, as we know it now, is incredibly new. Standards are evolving, architectures are still forming, and grid requirements change from market to market. And yet professionals are expected to connect batteries, power conversion systems, and controls — and to look at all of this in the perspective of real grid behavior, often without ever seeing the full picture.

My name is Sergey, and I'm a director of product engineering working on utility-scale BESS solutions. Over the past several years I've worked on real projects from system design to grid integration — and I've seen where things go wrong, and what actually works.

This course is built to give you that missing clarity. By the end, you will understand a battery energy storage system from the battery cells all the way up to the grid — not as isolated components, but as a whole connected system.

You will learn how batteries actually work, without unnecessary complexity; how the power conversion system and controls behave in real grids; and how full BESS systems are designed, operated, and integrated into real projects. And of course: how a BESS earns money, and why bankability matters so much for these systems.

We'll use simple explanations, practical examples, and real-world insights — so you don't just understand the theory, you understand how the whole ecosystem around the BESS works.

This industry doesn't need more narrow specialists. It needs people who understand the full picture and the full system. And that's exactly what we're going to build in this course.

The full course goes far deeper: 11 sections, 207 lessons, ~15 hours — cells, enclosures, PCS and transformers, the BMS/EMS/PPC control stack, fire safety (NFPA 855, UL 9540A), grid integration, project finance, and revenue. Start with the curriculum overview or the learning path.
