Event Response Protocol\n- **grid-failure**: Prioritize critical load (~15 MW) using LFP first, then NMC if needed. LTO should idle. Solar provides available power.\n- **freq-drop**: LTO must discharge immediately, proportional to frequency deviation. LFP provides secondary support for severe drops.\n- **solar-peak**: Absorb maximum solar by charging assets. Priority: LTO → LFP. Never use NMC for daily solar absorption.\n\n### 2.
