The Northland Regional Council in New Zealand received an application last week from Crest Energy, Ltd., to build a 200-megawatt tidal power plant just north of the country's largest city, Auckland. The proposed project, situated in the mouth of Kaipara Harbour, calls for two 20-mile DC cables that run across the harbor -- and the construction of a DC-AC converter and substation on land at the Hoteo River.

"Tidal power is predictable, sustainable, silent and invisible -- these advantages need to remain the focus, rather than the eight hours a day when tidal turbines produce little or no power. Tidal power complements other energy sources and will, eventually, be of importance to maritime countries." -- Anthony Hopkins, Crest Energy, Ltd., Director
