THE PROBLEM

The BESS industry is growing 30% annually.

Most professionals are learning on the job.

Battery energy storage has gone from niche to critical infrastructure in under five years. Utilities are deploying gigawatt-scale projects. Developers are racing to interconnection queues. Investors are committing billions. And the engineers, project managers, financiers, and executives running these projects are mostly figuring it out as they go.

The reason is simple: there is no shared body of structured knowledge. Vendor marketing oversimplifies. University courses are five years behind. And the people who actually know how BESS gets built — the practitioners shipping real projects — rarely have the time to teach.

The cost of learning on the job is real. It shows up in projects that can't get financed, products that get specced but never deployed, and decisions made on assumptions instead of data.

This course closes that gap.

WHAT YOU'LL LEARN

Six things you'll be able to do.

after this course.
01

Speak the language of BESS fluently

Cell chemistry, PCS, BMS, EMS, fire safety, bankability — understand every acronym in any project meeting and never feel lost again.

02

Read a BESS datasheet like a senior engineer

PCS specs, PQ curves, derating, transformer selection — know what matters, what doesn’t, and what vendors hope you won’t ask about.

03

Understand how BESS projects get financed

SPVs, PPAs, capital stacks, bankability — see what makes lenders say yes, and the deal-breakers that kill projects before construction.

04

Navigate the controls hierarchy with confidence

BMS, PPC, EMS, SCADA — know which layer does what, why it matters, and how a single grid signal reaches a battery cell.

05

Evaluate revenue stacking strategies

Energy, capacity, ancillary services — understand how a battery actually makes money across different markets and revenue models.

06

Avoid the mistakes that kill BESS projects

Fire safety, augmentation, bankability gaps — learn from real failures and project deal-breakers, not theoretical edge cases.

Engineers entering BESS

Coming from solar, wind, power electronics, or another technical field? Get the BESS-specific foundation you can't find in datasheets and YouTube videos.

AUDIENCE 02

Senior engineers & PMs

You already know power systems or energy products. This course fills the BESS-specific gaps so you can lead projects with confidence from day one.

AUDIENCE 03

Developers & financiers

You're evaluating BESS projects but need to understand the technology and bankability deeply enough to make billion-dollar decisions.

AUDIENCE 04

Executives & decision-makers

Understand the technology your team is shipping or buying — without going back to engineering school. Strategic clarity to ask the right questions.

This course is for you

  • You want structured knowledge instead of fragmented YouTube tutorials
  • You’re working in or moving into utility-scale battery storage
  • You need to understand both the technology AND project finance
  • You learn best from real practitioners, not academics
  • You want to avoid the mistakes that kill BESS projects

This course isn’t for you

  • You’re looking for vendor sales pitches or marketing fluff
  • You need a deep electrochemistry PhD course
  • You want shortcuts without understanding the why
  • You’re already a 10-year BESS veteran
  • You’re only interested in residential or behind-the-meter storage

The instructor

Built by a Product Director, not a textbook author.

I'm Sergey Syrvachev. I've spent 13 years in product management, including the last 5 in clean energy, building BESS, inverter, and EMS product lines from cell chemistry to grid integration. My focus is simple: turning technically complex hardware and software systems into products that can be specified, financed, and deployed in the real world.

This course is everything I wish I'd had when I started in BESS — structured, practical, and grounded in real projects, not theory.

QUESTIONS

Frequently asked questions.

How long does the course take to complete?
The full course is approximately 15 hours of video across 207 lessons. Most students complete it in 2–4 weeks, working through 1–2 hours per evening. You have lifetime access, so you can move at your own pace and revisit any section as needed.
Do I need an electrical engineering background?
No. The course starts with electrical foundations — Section 3 is a complete bootcamp covering everything from Ohm's Law to AC/DC, power vs energy, and grid basics. If you're an engineer or technical professional from any field, you'll have everything you need.
Is this for utility-scale BESS or behind-the-meter storage?
This course focuses on utility-scale, grid-connected battery energy storage — typically 1 MWh and above. While many concepts apply to commercial and industrial storage, the depth is specifically tuned for the projects, finance structures, and engineering decisions of grid-scale BESS.
Will the course be updated as the industry evolves?
Yes. The BESS industry is moving fast, and the course is updated as standards, technology, and market structures change. Recent updates include the 2026 NFPA 855 changes, large-scale fire testing requirements, and grid-forming inverter content.
Do I get a certificate of completion?
Yes — Udemy issues a certificate of completion when you finish all lessons. While it's not a formal accreditation, many students add it to their LinkedIn profile to signal their BESS knowledge to employers and clients.
Can my company buy this for a team?
Absolutely. Udemy Business offers team licensing, and individual enrollments work too. If you're training 5+ engineers, message me directly via LinkedIn — I can help coordinate group access and answer questions about how to structure team learning.
What if it's not right for me?
Udemy offers a 30-day money-back guarantee, no questions asked. If the course isn't what you expected, you get a full refund. Take this risk off the table — try the course, and if it's not a fit, get your money back.
Why is this hosted on Udemy and not on this site directly?
Udemy provides the best learning infrastructure for technical courses: video hosting, mobile apps, progress tracking, certificates, and Q&A. Hosting on Udemy lets me focus entirely on creating great content while you get the best learning experience. This page exists to give you a complete overview before you decide to enroll.
