WEB Aruba has a roadmap to reduce heavy fuel oil (HFO) consumption and increase renewable energy from 2014-2020. So far, WEB Aruba has reduced HFO consumption by 40% since 2005 through investments totaling $450 million, and increased renewable energy penetration to 17%. The roadmap aims to further reduce dependency on HFO and increase renewable technologies like wind, solar and energy storage. The goal is an additional 20% reduction in HFO consumption and increasing renewable penetration to 40% by 2018 through $211 million in investments. This will result in a total 60% reduction in HFO compared to 2005 levels and a cleaner, greener energy system for Aruba by 2020.

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

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
