Off-Grid Academy Field Journal — UK Grid Post-Mortems & DIY System Builds
Long-form British engineering dispatches fact-checked against BS 7671, Ofgem/NESO blackout reports, Ofcom IR 2030, and UK Water Supply Regulations 1999.
Every dispatch in the Off-Grid Academy Field Journal is researched and written for UK households. We examine real British infrastructure failures—such as the 9 August 2019 Low Frequency Demand Disconnection (LFDD) event and Storm Arwen’s 10-day rural overhead line collapses—and translate those lessons into step-by-step domestic hardware builds.
Each article includes a complete bench-matched hardware kit list, step-by-step commissioning checklists, statutory UK regulatory citations, and companion dead-tree print manuals.
