# BESS Academy

> A self-paced learning path covering grid-scale Battery Energy Storage Systems, the German energy market, and how BESS assets are built, operated, and commercialised.

Welcome to the **BESS Academy** — terralayr's foundational guide to Grid-Scale Battery Energy Storage Systems (BESS).

This learning path is designed for anyone new to the world of BESS and the German energy market. We start with the basics of electricity grids and build up to battery technology, market applications, and financial concepts. Each article is a short, focused read that builds on the previous one — work through them in order or jump to the topic you need.
