THE OPPORTUNITY: 500 GW - 20% OF GLOBAL ELECTRICITY GENERATION
▪ Most concentrated form of renewable energy enabling large amounts of energy with less equipment
▪ Production profile is more consistent and complementary to wind and solar, providing higher average revenue potential per MWh.
▪ Provides grid balancing enabling 100% renewable electricity systems.
▪ CO2 Reduction | 0.8 – 1.6 Gigaton annually

Wind and solar production for 2018 from the California Independent System Operator (CaISO)
Capacity: Solar: 13.5 GW Delivered 31.5 TWh in 2018. https://www.energy.ca.gov/almanac/renewables_data/solar/
Wind: 6.5 GW Delivered 14.2 TWh in 2018. https://www.energy.ca.gov/almanac/renewables_data/wind/
Wave: 6.0 GW Estimated 18.5 TWh production using 2018 wave data (can be increased by better site selection)
Wave production capacity distributed over four sites:
HUMBOLDT BAY NORTH SPIT, CA - 1500 MWhttps://cdip.ucsd.edu/m/products/?stn=168p1
DIABLO CANYON, CA – 1500 MW https://cdip.ucsd.edu/m/products/?stn=076p1
SAN NICOLAS ISLAND, CA – 1500 MWhttps://cdip.ucsd.edu/m/products/?stn=067p1
POINT LOMA SOUTH, CA – 1500 MWhttps://cdip.ucsd.edu/m/products/?stn=191p1
Wave production estimated based on measured wave data from these four sites with 30 min resolution. Solar and wind production has 1h resolution
1.5 GW capacity and 3750 G12 machines per site. G12 rated at 400kW per machine. Power matrix for G12.
Array assumptions: 95% availability, 3% array interaction, 4% electrical collection, 2,1% auxilary losses.
Additional smoothing from larger geographical dispersion not included on wave profile
This is NOT an optimal wave site study, the sites used were picked only based on availability of wave data.

WEEKLY PRODUCTION PROFILE - CALIFORNIA – OCTOBER 20TH - 27TH 2018
WAVE IS VERY CONSISTENT COMPARED TO SOLAR AND WIND
Wind (6.5 GW) and solar (13.5GW) production: Actual time series of the period Wave production (6.0 GW): Estimate based on measured wave data and CorPower power matrix
6 GW wave energy devices evenly distributed over four sites along the coast of California

ANNUAL PRODUCTION PROFILE – CALIFORNIA 2018
Seasonal profile is complementary to solar and wind. Better than base-load from seasonal balancing perspective.

COMBINED WIND & WAVE ARRAYS - NATURAL GRID BALANCING
▪ Natural time shift between wave and wind resource
▪ Higher capacity factor, reduced output variability
▪ Shared electrical infrastructure & operations teams
