  2. Agenda • Background • Project Definition • Data Acquisition, Interpretation & Equipment Selection • Thermal Calculations • Financials • Questions & Feedback

  3. Background An Overview Of The Energy Sector In Jamaica

  4. The electricity sector in Jamaica is in dire straits. • Equipment is aging and results in inefficient power generation. • Fuel cost is high. • Energy theft. • Affects many industries: • Healthcare. • Education. • Manufacturing. • Almost all civil services. • Stagnates economic growth.

  5. Project Definition Crafting An Engineering Solution For High Cost Energy

  6. Red Stripe suffers financially because of the cost of energy. • Red Stripe Jamaica Limited is the Brewer of the world renowned lager, Red Stripe. • Power comes from the Jamaica Public service Company. • Number six heavy fuel oil (process steam) is purchased from the single local refinery PetroJam. • High electricity and process steam requirements.

  7. Data Acquisition, Interpretation & Equipment Selection An Examination Of Electrical Demand Requirements & How To Meet It

  8. Data from the SCADA system was extracted and examined.

  9. Two 1.131MW gensets are needed based on the energy requirements.

  10. The GE Jenbacher JMS 416 is selected because it meets the requirements.

  11. Thermal Calculations The Determination Of The Amount Of Process Steam Available From The Engine

  12. Calculating steam enthalpy.

  13. Calculating enthalpy of incoming and outgoing exhaust gas.

  14. Energy rate balance. • The following formula was used to calculate the available saturated steam at the required pressure of 9 bar.

  15. Allocating both engine available steam and additional steam.

  16. Financials The Confirmation Of The Quality Of This Investment

  17. Financial metrics validate the undertaking of the project. • CAPEX @ Year 0 ~$401,000,000 • IRR Using Future Cash Flows = 83.8% • Savings increase yearly. • Payback happens within two years.

  18. Current charges in Jamaica.

  19. Projected Project fuel costs in Jamaica.

  20. Project experiences payback in 15 months with a strong IRR. *Abbreviated from 6 years

  21. Next Steps

  22. Questions & Feedback
