3. Facility Overview Facility Staffing Commercial
507MWnet Combined Cycle Power Plant
LNG Import Terminal and Re-gasification station
2MGD Desalination Water Production Plant
Staffing
77 total number of EcoElectrica Employees
67 positions in the O&M Organization
40 positions form O&M allocated to the power plant, .07/MW
Commercial
100% contracted with PREPA for 22 years
93% availability / 45% thermal efficiency contracted guarantee
Facility dispatched from 54% to 100%
Energy priced fixed annually up to 76% dispatch, above 76% dispatch price is based on spot offers

4. EcoElectrica in the System
First IPP integrated to the electric system and only power plant on natural gas.
9% of the electric system installed capacity of 5,700MW.
13 – 15 % of the island annual energy production of 23,000MkWhr.
Environmentally cleanest and best thermal efficiency power plant on the island.
Ancillary services provider as any other power station on the electric system.
One of 10 LNG Terminal’s in US Borders.

5. Operational Experience
Power Plant
Stable plant reliability, achieving contractual availability.
Base loaded power plant with daily load following dispatch.
> 90% service factor, ~80% capacity factor.
~ 80k EBH, 3rd W501F fleet leaders
Three fuel capability, on-line fuel transfers from NG to Diesel and from NG to LPG.
LNG Terminal
~99.5% annual availability with >99.9% reliability.
128 LNG ship un-loadings w/out safety incidents.
Exceeding security requirements from Federal Agencies
Annual inspections from FERC and USCG consistently w/out material findings or recommendations.

6. LNG Terminal Receiving Storage Re-gasification 136,000mt3 tankers
24 hrs total unloading time
Storage
160,000mt3, Double containment
Un-cooled / atmospheric pressure
Re-gasification
2 X 93 MMSCFD, heat source from CT’s inlet air
Controlled temperature rise from -256oF to 40oF

7. Production Costs Fuel Cost Thermal Efficiency O&M Costs
NGCC – low O&M cost / high efficiency
Fuel Cost + Efficiency + O&M Cost
Fuel Cost
accounts for 49% to 92% of the total production cost of the Power Plant
Thermal Efficiency
energy conversion factor from fuel to electricity
normalized to the best thermal performance in the system this component accounts up to 38% of the total production cost
O&M Costs
accounts for 26% to 5% of the total production cost of the Power Plant
on a gas turbine burning natural gas vs oil#2 the O&M cost is reduced by a factor of 30%.
Oil#2 SC – high fuel cost / low efficiency
Coal CFB – high O&M / low fuel cost
PR electric system cost estimates. Based on actual fuel cost and IPP’s PPOA base energy cost.

8. Actual gap from crude to LNG is above 40% including estimated
Production Costs
Actual gap from crude to LNG is above 40% including estimated
transportation costs.

9. Environmental Natural Gas Inherent Controls
Fossil fuels lowest CO2, 30% less than Oil and 43% less than Coal.
Nitrogen Oxides is less than 25% than oil.
Almost zero Sulfur & Particulates.
Controls
Steam injection and SCR with ammonia injection for NOx reduction.
