PG&E Wave Energy Study
• Initiated 2007• Two sites considered– Mendocino County• Dismissed due to inadequate harbor
– Humboldt County offshore Manila

Project Scope• 3 nm offshore, 45m deep• Up to 4 arrays, max of 30 generators• 5MW max total output• 12kV transmission lines to Fairhaven– Gen Tie Infrastructure– Power Conditioning Devices (depending in final agreement)– Subsea Transmission Cable
• 5 cables, one for each array and one spare
• Environmental monitoring buoys– Up to 6 environmental monitoring buoys– Up to 6 US Coast Guard approved markers as navigational
aids
