Morphology
The meaning 'at the highest point or level' is directly derivable from combining 'at' (location), 'its' (possessive determiner) and 'peak' (highest point). This preposition + possessive + peak pattern is a straightforward, cross-linguistically common compositional construction, so a B1 learner who knows the constituent words will understand the phrase.
Etymology
At its peak comes from the simple picture of something reaching the top of a mountain or hill. When something is on the top it is at its strongest or highest, so at its peak means 'at the highest point' or 'at the greatest strength'.
