District Cooling in Canada and Jamaica -- Precedents and Prospects

  1. 1. District Cooling in Canada and Jamaica – Precedents and Prospects
  2. 2. New Leaf Power- Background New Leaf Power & Conservation Solutions Limited is a full service energy solutions company serving Jamaica and the Caribbean. The Company won a Climate Change Innovation Award from the World Bank for it work developing an solar energy hub for an offshore fishing island off the cost of Jamaica on the Pedro Banks. NLP has partnered with Bluerise to explore the development of Cooling Districts in the Northern Caribbean in general; Jamaica in particular.
  3. 3. The Cayman Trench The Cayman Trench, Bartlett Deep, or Bartlett Trough is a submarine trench on the floor of the Caribbean Sea between Jamaica and the south-eastern tip of Cuba. The trough has a maximum depth of 25,216 feet (7,686 m) with near freezing temperatures; the deepest point in the Caribbean Sea. Paradoxically, some of the world’s hottest (up to 400 degrees Celsius) and deepest deep-sea vents are found in the Cayman Trench some 5 km (3.1 miles) below the surface of the sea.

  6. 6. SWAC PRECEDENTS IN CANADA Enwave: •Deep Lake Water Cooling (“DLWC”): •Commissioned in 2004, DLWC anchors Enwave’s district cooling system •DLWC is a renewable, “geothermal” source of cooling that allows Enwave to offer our customers several quantifiable benefits including a reduced environmental footprint and a hedge against volatile electricity prices

  8. 8. Precedents in Canada Cont’d Purdy’s Wharf The Purdy’s Wharf office complex sits on the waterfront of Halifax, and buildings extend out over the harbour on pilings. Cold seawater is drawn from the bottom of the harbour through a pipe to a titanium heat exchanger in the basement of the complex where the closed loop of water, cooled by the sea water, is then pumped to each floor of the building where fans blow air over the cooling pipes to cool the air. The seawater is returned to the harbour floor. The project was jointly funded by the Government of Canada and the building’s developer, and was intended to serve as a demonstration of the technology. The project was constructed from 1983 to 1989 and consists of an 18-story tower, a 22-story tower, and a four- story retail centre. The total area cooled by the system is 65,000 sq. meters.

Cost of Developing SWAC in Jamaica KEY FINANCIAL METRICS FOR MONTEGO BAY PROJECT: Phase I Required Investments: -Sponsors Equity (this round): US$2 MM -Project Finance:US$40-44 MM -Phase II Required Investments: -Project Finance: US$55-60 MM -Projected Levelized Cost of Power : 14-15 cents per kWh -Projected Rate of Return: 14-16%
  11. 11. Developmental Phases of Montego Bay SWAC project Prefeasibility - 3 months Feasibility - 6-12 months Bathymetry Study, Environmental Impact, Offtaker Demand Study, Permitting and Interconnection & Financing  Client Recruitment - 12 months to ongoing  Construction - 12 - 18 months  Commissioning and Burn In - 2-3 months  O&M and Expansion including possibly OTEC conversion - 30-50 Years
  12. 12. Cooling District Opportunities in Proximity to the Cayman Trench Jamaica, Cuba and Cayman all benefit from access to an inexhaustible source of cold deep sea water based on their proximity to the Cayman Trench. Undersea currents brought this extremely frigid water from the Artic thousands of years ago and the Trench has the regions coldest and hottest waters. New Leaf Power and Bluerise have partnered to pioneer the development of this capital intensive infrastructure.
  13. 13. Cooling District Benefits: • Lower cooling costs • Predictable costs • No Noise Pollution • Reduced dependence on imported fuels which require foreign exchange • Significantly less CO2 emissions • Climate Change Mitigation • Reduced emission of ozone- depleting refrigerants • Supports protected agriculture and cold water fish farming • Supports innovative spa and recreational facilities like ice rinks and tropical ski slopes
