Accomplished till now
40% reduction in HFO Consumption
while prices increased with 170%

5. Current realities (Transition Phase)
• Higher Fuel Oil consumption, due to:
– Increase wind energy (Renewable Energy) production resulting in
equipment not operating at optimal efficiency levels during the
transition phase
– Roadmap to MSF Zero Water plant “100% SWRO” resulting in
equipment not operating at optimal efficiency levels during the
transition phase
• Drop in electricity sales combined with a high peak demand
The roadmap to HFO reduction & renewable energy increase 5

6. The road ahead
Strategy WEB Aruba for 2014–2018:
• Further reduce dependency on Heavy Fuel Oil
• Enhance production plant automation with Intelligent
Generation Management System (IGMS)
• Introduce Energy Storage solutions
• Further implementation of affordable renewable
technologies
