33% into a course on Grid-Scale BESS, by Udemy and it's already humbling. As an electrical engineer, I walked in thinking I had a decent handle on Battery Energy Storage Systems. Turns out, what I actually knew was maybe 5% of what this course covers. Grid-scale BESS is a whole different world of complexity — sizing, integration, protection, controls, economics — and I'm only scratching the surface. Shoutout to the instructor, Sergey Syrvachev. He's not a native English speaker, and honestly, that's turned out to be a plus — it makes me listen more carefully to every word, and I end up retaining more because of it 😂 If you're an engineer or anyone curious about BESS and grid-scale energy storage, I'd genuinely recommend checking this course out. Will share more as I progress through the rest of it.
Reading BESS from the project side, not the battery side
Dr. Carlos Rodríguez — Head of Yield and Performance - Australasia and APAC Renewables Senior Engineering Project Manager, RINA —
posted on LinkedIn, .
Alongside the practical experience gained through projects over the years, I recently completed several BESS courses that go beyond battery chemistry and manufacturing, focusing more on aspects relevant to utility-scale project design, deployment and operation. These included BESS architectures and design choices, AC- vs DC-coupled systems, grid-forming vs grid-following systems, performance and degradation, augmentation, warranties and LTSA, project development and construction, financing and bankability, optimisation and revenue stacking, as well as safety, permitting and compliance, among other topics. I found this particularly useful because understanding BESS from a project perspective requires looking beyond the battery itself and considering how the technical, commercial and regulatory aspects come together throughout the asset’s lifecycle.
Just wrapped Sergey Syrvachev’s highest-rated course on grid-scale Battery Energy Storage (BESS) — 14.5 hours covering everything from cell chemistry to grid economics. […] Bankability is the real product. The banks financing these projects aren’t underwriting the battery — they’re underwriting the risk structure behind it: tier-1 OEM status, independent DNV due diligence, and LTSA-backed performance warranties are what actually gets a project financed. […] It’s clear the fundamentals matter as much as ever — but the technology curve keeps moving fast.
Just completed a course on Battery Energy Storage Systems (BESS) by Sergey Syrvachev. With ongoing involvement in multiple BESS projects across Pakistan and Western Europe, the knowledge gained will further strengthen my understanding of BESS technologies, market dynamics, and real-world applications.

Energy storage is one of those fields where the learning curve is steep and almost nobody hands you a map. Sergey Syrvachev’s Grid-Scale BESS course is the exception. 200 lectures covering cell chemistry, system architecture, controls, project finance, grid integration and energy markets. Built by someone who has actually done this work at scale. […] I am at the beginning of my journey here and intentionally going deep on the fundamentals before anything else. This course is exactly that kind of foundation. Highly recommend to anyone serious about becoming a BESS aficionado!
Technical performance and bankability in one place

I recently completed Grid-Scale Battery Energy Storage (BESS). Working on BESS projects globally makes it essential to keep strengthening my understanding of both technical performance and project bankability. This course brought those two areas together. Thank you, Sergey Syrvachev, for a practical and informative course.
Merit Order in 3 minutes - and that’s not a complaint! I’ve been interested in energy storage since I moved into energy quant trading. I believe physical assets offer a unique edge, with almost limitless potential across ever-changing markets (and regulations). To better understand the “physics” of BESS, I took a course a friend recommended. 14.5 hours later, I think I will recommend it to a friend myself. The course covered, it seemed, everything: from the depths of chemistry and physics (my academic background helped me there) all the way up to bankability and revenue streams. And yes - merit order got just 3 minutes, which shows how much ground 14.5 hours covered. Granted, I work in energy, so for me this was more about filling gaps than learning a genuinely new field - but I absolutely got my time’s worth. It also left me with an idea: adding battery dispatch optimization to my personal forecasting project. A forecast on its own is just a number; feeding it into a dispatch decision is what turns it into something practically valuable. Big thanks to Sergey Syrvachev and Udemy for the course!
Just completed the Grid-Scale Battery Energy Storage (BESS) Complete Guide by Sergey S. on Udemy. On the technical side, the course covered system architecture and how the PCS, BMS, EMS and PPC work together, as well as safety and environmental aspects, including fire protection and noise assessments. Where it added the most for me was the commercial and financial side: how degradation and augmentation assumptions feed into the financial model, how revenue can be stacked beyond arbitrage, and what lenders look for in warranties and performance guarantees, all of which play a major role in a project’s success alongside the technical fundamentals. Thank you Sergey S. for sharing such valuable insights. I’d recommend the course to anyone looking to build a well-rounded understanding of grid-scale storage. Plenty more to learn in this space!
