Reduced Water Demand by Reuse
• Alternative Water Supplies To Freshwater:
– Brackish or Waste Water for Power Plant Cooling
– Reuse/Recycle Water for Gas Production
– Dry Cooling, Advanced Condensing Cooling Towers

Reduced Water Demand via Indirect Dry Cooling
28 November 2013 27
This power station in Mpumalanga, South Africa, comprises 6 x 686 MW units,
and operates with the largest indirect dry cooling system in service world wide.
The indirect cooling plant was built by DB Thermal in 1984. It includes 6 Cooling Towers,
each 165m high with a throat diameter of 102m.

IV. Workshop Objectives and Desired Outcomes
• All Energy Technologies Exhibit Some Vulnerabilities to the Consequences of the Changing Climate
• Each Country or Region Will Likely Have a Unique set of Urgencies
• New and Strengthened Technologies Can be Made More Resilient to Many Challenges
• Better Information Can Influence Parameters of Design
• Energy RD&D Planners Should Consider How the Changing Climate Will Alter RD&D Priority-Setting
• What are the Top Priorities for Increased RD&D Investments?
• What are Top-Priority Supporting Policy and Analytical Needs?

Additional Questions Needing Attention
• How do you define climate preparedness and resilience for energy systems?
• What tools, data, and information would be most helpful in evaluating climate preparedness and resilience?
• What lessons can be learned from the private sector, or from public-private partnerships in developing response strategies and deploying climate-resilient energy technologies?
• What are the elements of an effective, integrated framework for monitoring, evaluating and communicating progress towards a climate resilient energy system?
• What approaches would be most effective to communicate results of energy sector vulnerability assessments to climate change, and to inform decision-making for prioritization or restructuring of research investments and related policies, and achieve desired outcome?
