Battery & Storage · 2026-07-03 · Holger Roswandowicz · HR Energiemanagement GmbH

Some of the hardest topics in storage and power markets are easier in two minutes of film than on a page. Stromfee Studio is a media library of 236 short videos in 18 sections — "explainer films and stories, short and clear."

Stromfee Studio — a media library of 236 explainer films

A full English Glass-BESS series

For English-speaking audiences the key sections are the Glass BESS role films — the same storage asset explained for three different readers, each as a 14-part set:

Glass BESS — Investor (14)What the battery earns vs. what the market allowed — bankability as a measurement. Glass BESS — Direct Marketer (14)Dispatch, capture rate and the trader-accountability view. Glass BESS — Accounting (14)The register-true numbers behind the settlement.

And the rest of the shelf

Beyond the English role films, the library opens with "BESS — The Film" (a full walk-through of the register-true digital twin) and runs from a 47-part Technician School — the BESS container from the inside to a Day-Ahead learning series, an MSCONS billing set, market-news clips and a 37-part academy. It is free and needs no login.
