Introduction • Ecopower International is a development and advisory firm
with a focus on renewable energy-related opportunities.
• Our team consists of senior international renewable energy and financial services experts with over 10 years of experience with development, finance and construction of a.o. Wind Power, Wind-Diesel Hybrid and Seawater Air-conditioning projects.
• Our mission: To contribute to improving sustainability by
developing sustainable energy and related projects, while optimizing sustainable social and economical development.
Characteristic of Caribbean Island Nations
• High dependence (over 90%) on foreign fossil fuels • Mainly diesel generation (HFO some LFO) • High percentage of export earnings spend on oil products • Exposed to negative impacts of climate change (sea level
rising, hurricanes, floods, coral reef in danger) • Abundant (untapped) local (renewable) energy sources • Islands are naturally the first places where alternative
energy solution become feasible. We should use that in our advantage
– (SWAC Airport and Aqualectra, Ecopark Curacao, Wind Diesel Bonaire and TNO Aruba).
Island resources
• Solar (intermittent, day and night, backup needed) – All islands have plenty of sun – Every moment of the day 10.000 times the energy we needed reaches
the earth • Wind (intermittent, no wind days, backup needed)
– Many island have reasonable to good wind (Hurricane risk) • Ocean (No backup needed)
– All islands have the ocean (OTEC, Tidal) – Seawater air-conditioning
• Hydro power (No backup needed) – Belize, Cuba, Dominica, Jamaica, St Vincent and Suriname)
• Bio mass and Waste to Energy (dependent on amount waste/bio mass, No backup needed)
– Most island have bio mass potential, all have a waste problem • Geo Thermal (No backup needed)
– Some islands have geo thermal possibilities (St Lucia, Dominica, St Kits) • Oil and Gas (No backup needed)
– Some islands
Energy cost (HFO at 100USD/bbl)
Price USD/kWh*
Price with Backup*
Diesel HFO 0.19 - 0.25
Diesel LFO 0.28
Gas Engine LNG 0.15 - 0.18
Wind 0.09 - 0.13 0.19 - 0.23 Back-up needed
Solar PV 0.20 - 0.24 0.25 - 0.28 Back-up needed
SWAC 0.17 - 0.23 No Backup- needed
W2E 0.30 - 0.50
* Equivalent centralized energy production costs (thus no end-user energy costs)
Seawater air-conditioning Introduction • Many businesses approximately 70% of total energy consumption is
cooling. With the high electricity tariffs and the proximity to the ocean, Seawater air-conditioning seems a logical option for the Airport Complex.
• An additional benefit, making it a potentially perfect fit for the CAH vision, is that Seawater air-conditioning has the potential to serve as a source for an Eco Park for high-end research, development and exploitation of aquaculture, agriculture and other spinoff activities like ocean thermal energy conversion (OTEC).
• Aqualectra and CAH have decided to coordinate the development of the respective SWAC projects (maximize synergy),
Seawater air-conditioning Project: Initial dimensions • Proven technologies • Replace conventional A/C completely or partially • Several sites (Hawaii, Bora Bora, Japan & New York) • Hurricane and tsunami resistant
• 3000 Ton AC • Seawater intake line: 6 km, 850m depth, 6 C • Effluent line: 100 m depth • Pump station and shore landing: 600 m2 • Distribution system:
– Length main distribution line: 8500m – Length secondary distribution line: 1500m
Seawater air-conditioning Facts/value drivers • SWAC is Basic Infrastructure providing up to 70% of the total energy
(30% will be electricity). • Reduce energy consumption for cooling with 13.5Million kWh (90%)
per year. – Reduction of the dependence of fuel imports (thus foreign currency
expenditure) – Save ca.3.0 Million liter fuel per year (ca. ANG 2.0-4.0 Million/year,
depending on fuel type). – Save roughly 1.0-2.0MANG/year in cross subsidies by the other
consumers to the preferential tariff. – Reduction of GHG emissions of approx. to 11.000 tons CO2 per year
(Equivalent to 1,750 cars). – Eliminates use of refrigerants and other cooling tower chemicals.
Seawater air-conditioning Facts/value drivers • First hour clients benefits:
– Long term low price guarantee – Long term reduction in customer’s cooling cost of up to
50%. – Stable and predictable cooling cost for 15 years, not
subject to oil price volatility. • SWAC is a reliable, renewable and quiet
alternative. • Possibilities for research, development and
exploitation of: – Aquaculture and Agriculture using the clean water from
deep sea – Desalination, Water Bottling and ocean thermal energy
conversion (OTEC).
Seawater air-conditioning Current status and Planning • Project development phase:
– Signing required commitment with minimal number of (first hour) customers • CTEX (committed) • CAP (final approval phase) • Other potential customers: Meteo, NAATC and Curinde, FOL, Coast
Guard, Hato handling, Swissport, KLM, Goddard etc. – Start Engineering process incl. high resolution seabed survey – Permitting incl. environmental impact assessments – Construction contracting – Structuring and Financing
• Financial closure and start construction phase Q3-Q4 2013 • Start Operations approx. Q4 2014
