BESS Engineering Foundations
A full engineering course beneath the core course — energy and power language, DC and AC fundamentals, the battery operating window, degradation, the PCS and transformer interface, P-Q capability, and round-trip efficiency.
- Energy, power, MW, MWh and durationWhy a '100 MW battery' is an incomplete spec — and what an engineer says instead.
- Voltage, current, resistance and AC/DCThe full DC and AC toolkit, with current as the hidden enemy.
- Battery architecture and operating windowFrom a single cell to a 5 MWh container, plus C-rate, SOC, DOD and SOH.
- Degradation and end of lifeAging curves, calendar vs cycle aging, augmentation, and lifetime RTE.
Fire Safety for BESS
A focused deep dive into BESS safety, thermal runaway behavior, testing logic, hazard analysis and emergency planning.
- Fire dynamics and protection layersHow an initiating fault becomes venting, thermal runaway, propagation, fire and deflagration.
- How to read the regulatory landscapeEnforceable codes vs installation standards vs product certifications vs test methods vs guidance.
- North American codes and standardsNFPA 855, the IFC/NFPA 1 route, and how adoption actually works on a given site.
- European regulatory and fire-safety frameworkNavigating Europe without pretending it has one harmonised fire code.
BESS Warranties, LTSA & Performance Testing
One disputed capacity test, followed for four hours — the guarantees, the measurement boundaries, the acceptance tests, the availability accounting, and the claim and remedy that follow.
- The Year-3 test that "failed"The case spine: 365 MWh against a stated floor of 380, and a first vote taken before any evidence.
- The warranty stack and risk ownershipWhich document promises what, and who carries the risk when they disagree.
- Definitions that decide moneyWhere the quantity lives and against what reference — the wrong boundary beats a right method.
- Degradation, operating envelope and augmentationWhat the asset is allowed to do, and what that permission costs later.
How a Battery Gets Paid
A full course on grid-scale BESS revenue — from the flexibility gap and the gross-to-net loss bridge to revenue stacking, the merchant engine, the Capacity Market, and a live 50 MW / 200 MWh stacking model.
- Why storage existsThe flexibility gap, learning curves, and the duck curve.
- What you are actually buyingSite anatomy, the four numbers, chemistry, and what an OEM really sells.
- The hidden costsThe five optimistic assumptions, the gross-to-net loss bridge, and round-trip efficiency.
- Revenue building blocksThe revenue equation, the three markets, and the offtake risk dial.
