History

Early in the twentieth century, electricity generation and distribution was managed by local councils or municipal departments. An electricity network was established in Hastings in 1912, with a power house in Eastbourne Street. Following changes to national legislation, the Hawke's Bay Electric Power Board was formed in 1924.
