Morphology

islanded = island (transparent) = island + ed

Formed by a productive adjectival/past-participle suffixation from 'island' meaning 'to isolate', so the sense 'made or operating as an island (i.e., isolated from the grid)' is directly inferable.

Etymology

Islanded comes from island plus the ending -ed, meaning 'made an island' or 'left alone'. Think of a real island that must work by itself; an islanded electrical system is cut off from the main grid and runs 'alone' to keep power working.
