GENERAL DESIGN CONSIDERATIONS. When a given earth station is to transmit multiple digital carriers, consideration should be given to the use of an antenna larger than 3.5 meters in order to minimize the HPA power requirement. It may also be necessary to use a larger than minimum size antenna in order to meet the G/T specification, if the earth station is located outside of the downlink reference gain contour given in Figure 2. Although the design of the earth station is the sole responsibility of the user, to avoid service problems, Alpha Lyracom's customers are encouraged to consult with Alpha Lyracom, in advance of selecting equipment, to ensure that their selection of the optimum antenna and HPA size are in compliance with the requirements set forth herein.

GENERAL DESIGN CONSIDERATIONS. The plant will meet the following requirements: • Location Terre Haute, Indiana • Plant Fuel Capability: Anode Fuel Gas Makeup: Coal/Pet Coke derived syngas, natural gas (one at a time) Oxidizer Burner Fuel: Natural gas or peak shave gas • Overall Plant Performance Targets (Nominal Values) Rated Power Output 2.0 MW (Net AC), lower on syngas due to lower Btu value of syngas Power Output Turndown 25% to 100% of Rated Sustainable Output (stable operation below 25% and islanding) • Electrical Characteristics Output Voltage 480 Volts Power Quality: IEEE Standard 519 Power Factor Range 0.90 Lag to 0.90 Lead at Rated Output Power Output Phase 3 Phase, Wye, 4 Wire Frequency, Hz 60 DC to AC conversion efficiency 95% or greater Black Start Capability Not included; connection to grid will be required or stand alone 480Vac generator provided • Plant Controls Designed for unattended operation with local and remote dispatching/control • Height 25 feet • Plant Constructability Basis Modular (skidded) design. Truck- transportable skids complete with pre- installed piping, valves, insulation, instrumentation, and electrical wiring. The plant will be configured to minimize number of skids to limit footprint requirements and to limit interconnectivities during installation. • Plant Design Life Expectancy 35 years • Equivalent Availability 95% • Fuel Cell Stack Modules Number required in Plant Two Stack Module Design Internally Insulated Nearly-Cylindrical Vessel, truck-transportable modules, each containing four fuel cell stacks Fuel Cell Type/Configuration Carbonate/DFC (Direct Internal Reforming/Indirect Internal Reforming (DIR/IIR) Operating Temperature 1050-1194°F Operating Pressure <1 psig Stack Module Rated Output 1.0 MW (net ac) on natural gas Design Service Life Expectancy 10,000 – 40,000 hours, based on fuel cell stack generation Replacement Philosophy Replacement fuel cell stack modules will be available to meet the 35-year design operating life of the plant, and will be designed to fit into the plant without requiring modifications to the balance of plant components. • Noise 60 dB(A) or less at 100 feet from the plant boundary (fence). Fuel Cell Stack Conditioning Requirements All fuel cell stack modules will be preconditioned before being installed at the site. Plant Control Requirements The plant will be designed for unattended operation with local and remote dispatching/control. The control system will be able to communicate with a remote monitoring station loc...
