Facility overview

Facility Overview

  • Facility

    • 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


  • Ecoelectrica in the system

    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.


    Operational experience

    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.

    Production costs

    Production 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.


    Production costs1

    Production Costs

    Actual gap from crude to LNG is above 40% including estimated

    transportation costs.


    Environmental

    Environmental

    Natural Gas Inherent

    • 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.

    6 – 22 - 3


    Results

    Results

    • Reliable 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.
