On April 30, any unused energy credits are zero’d out and the accruals start fresh on May 1. These dates coincide with the beginning and end of the City's fiscal year.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with City of Geneva Utilities before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
