TIDAL ENERGY POTENTIAL IN CHILE
Chile has one of the best tidal Available energy:
energy sites around the world ~2.5TWh/year
The Chacao Channel is one of the (using 20% of the available mean
power)
most interesting sites according to
different variables (high tidal currents,
bathymetry, electric network,
infrastructure, etc.)
Chacao Channel
0.7-0.9TWh/year
Corcovado Gulf
0.3TWh/year
Source : Garrard Hassan (2009) 2nd Angostura
1.3TWh/year
Congreso Bienal Internacional CIGRE 2013
WAVE ENERGY POTENTIAL CHILE
Chile: Annual mean wave power density
30-120 kW/m
Estimated gross available wave power:
200 GW
Challenges:
Scarse and short term data
Complex and highly energetic wave
climates (multi modal wave spectrums)
Insufficient bathymetric information
and marine biosphere knowledge
Source : Gunn and Stock-Williams (2012)Congreso Bienal Internacional CIGRE 2013
GENERAL OBJECTIVES
To perform detailed bathymetric and oceanographic studies to
characterize tidal energy resources in the Chacao Channel.
To investigate environmental issues, technical, economical and
regulatory aspects and market barriers for marine energy
extraction in Chile.
To define suitable areas for device deployment and testing.
To support the NCRE implementation process that Chile has
defined.Congreso Bienal Internacional CIGRE 2013

CHALLENGES FOR THE NEXT STAGE OF MARINE
ENERGY DEVELOPMENT IN CHILE
• Chile has one of the highest marine energy resources in the
world and could play an important role in the current pre-
commercial marine energy extraction phase
• There are good scientific and technical capacities available that
can contribute to make marine energy extraction real
(leapfrogging strategy)
• If devices work in Chile, they can do so almost everywhere
(highly energetic climates, earthquakes and tsunamis,
extremely rich marine biosphere, etc.)
• Chile is a natural laboratory for coastal sciences and technology
advancement and testing
• Innovative regulatory policies and market strategies should be
designed and implementedYou can also read
