Story summary

FEMA designated the Waiau power plant site as a 100-year flood zone, effective in June, raising questions about permits and federal funding for HECO's $1.15 billion upgrade.
HECO's vice president Jim Kelly stated the plant has operated safely since 1938, but the new designation may complicate financing.
