2Objectives Facility Overview EcoElectrica in the System Operational ExperienceGas Natural Impact on Production CostsEnvironmentalResultsTSA Functional Description
3Facility Overview Facility Staffing Commercial 507MWnet Combined Cycle Power PlantLNG Import Terminal and Re-gasification station2MGD Desalination Water Production PlantStaffing77 total number of EcoElectrica Employees67 positions in the O&M Organization40 positions form O&M allocated to the power plant, .07/MWCommercial100% contracted with PREPA for 22 years93% availability / 45% thermal efficiency contracted guaranteeFacility dispatched from 54% to 100%Energy priced fixed annually up to 76% dispatch, above 76% dispatch price is based on spot offers
4EcoElectrica 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.
5Operational Experience Power PlantStable 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 leadersThree 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 AgenciesAnnual inspections from FERC and USCG consistently w/out material findings or recommendations.
6LNG Terminal Receiving Storage Re-gasification 136,000mt3 tankers 24 hrs total unloading timeStorage160,000mt3, Double containmentUn-cooled / atmospheric pressureRe-gasification2 X 93 MMSCFD, heat source from CT’s inlet airControlled temperature rise from -256oF to 40oF
7Production Costs Fuel Cost Thermal Efficiency O&M Costs NGCC – low O&M cost / high efficiencyFuel Cost + Efficiency + O&M CostFuel Costaccounts for 49% to 92% of the total production cost of the Power PlantThermal Efficiencyenergy conversion factor from fuel to electricitynormalized to the best thermal performance in the system this component accounts up to 38% of the total production costO&M Costsaccounts for 26% to 5% of the total production cost of the Power Planton 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 efficiencyCoal CFB – high O&M / low fuel costPR electric system cost estimates. Based on actual fuel cost and IPP’s PPOA base energy cost.
8Actual gap from crude to LNG is above 40% including estimated Production CostsActual gap from crude to LNG is above 40% including estimatedtransportation costs.
9Environmental 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.ControlsSteam injection and SCR with ammonia injection for NOx reduction.6 –
10ResultsReliable operation in compliance with PPOA warranties and within best 10% of comparable operations worldwide.Excellent relation with Federal and Local Regulating Agencies.Perfect safety record on the LNG Terminal Management.~ 7 years w/out lost time accidents in the facility.OSHAS 18,001 certified facility.2008 EPA Environmental Excellence Award.ISO 14,001 certified facility.Best O&M team in the sector.
