Data centres, VPP, energy storage and heat–power each offer nine lessons in three modules. The three lessons in each first module are free. Modules two and three are included in monthly and annual Intelligence membership, with technical explanations, figures, engineering cases, exercises and worked answers: 24 member lessons across four topics.
The existing price remains US$19.90 monthly or US$199 annually. One subscription includes all four topics; active members do not buy courses separately. Knowledge libraries, technology overviews, existing topic calculators, data checklists and self-service diagnostics remain free.
Member lessons are available during an active subscription. Topic courses are currently in English and Simplified Chinese. Custom project analysis, design review and personal consulting require a separate scope and quotation; they are not included in the subscription.
All nine lessons are published: module one is free, while modules two and three require membership. Read the concepts, technical mechanisms and engineering cases in sequence, then attempt the exercises. Numerical examples distinguish teaching assumptions from field evidence.
