1. Summary This Product Specification describes the Capstone model C65 microturbine system. The microturbine is a stationary power generating system that provides on-site electrical power for primary or standby applications, and for base loading and/or capacity additions. A microturbine can generate power in parallel with an electrical utility (Grid Connect mode), or isolated from the utility (Stand Alone mode). The system consists of a turbine engine, solidstate power electronics, fuel system, and several outdoor-rated enclosure configurations. Major turbine engine components include a compressor, a recuperator (exhaust gas heat exchanger), a combustor, a turbine, and a generator. The turbine engine is air cooled and supported on air-lubricated foil bearings (air bearings). The compressor impeller, turbine rotor, and generator rotor are mounted on a single shaft. The power electronics are solidstate, double conversion type, producing three-phase alternating current output power from the high-frequency alternating current engine output. 2. Models and Configurations Capstone C65 microturbine systems are available with several optional configurations. The available model and configuration options covered by this Product Specification are summarized in Table 1. Refer to Capstone Fuel Requirements Technical Reference (410002) for additional information regarding Capstone fuel definitions and requirements. The available microturbine configurations are as follows: Heat Recovery Module (HRM) A module mounted on the top of the microturbine enclosure incorporating an exhaust-to-water heat exchanger for combined heat and power (CHP) applications. Microturbine configurations with the HRM installed are considered integrated Combined Heat and Power (ichp) enclosures. A standard copper HRM utilizes a non-asme heat exchanger core. Not all microturbines are available in a standard ichp enclosure; however, the HRM may be purchased as a separate accessory with an ASME-stamped copper or stainless steel core. Stainless steel cores are required for sour gas applications. Dual Mode (DM) Incorporates an internal battery pack and battery controller that allows the microturbine to operate without a utility grid (i.e., Stand Alone mode). Microturbine systems utilizing the DM configuration are capable of operation in either Grid Connect mode or Stand Alone mode. Catalyst Reduction Module (CRM) An enclosure module incorporating a carbon monoxide (CO) reduction catalyst. The CRM is only intended for use with pipeline quality natural gas. (LE) A microturbine enclosure configuration that incorporates a CRM for reduced CO emissions when operating on pipeline quality natural gas. High Humidity (HH) Includes heaters and specially treated electrical connectors to prevent corrosion when the microturbine is not in operation. The heaters require externally supplied power to reduce the local relative humidity within the microturbine enclosure. This configuration is intended for applications where the average annual relative humidity exceeds 80%. GasPack An externally mounted gas compressor accessory to enable use of low pressure natural gas. The GasPack is only intended for use with pipeline natural gas. 460044 Rev D (May 2013) Page 4 of 15
Hybrid UPS (HUPS) Incorporates a secondary inverter to provide reliable power to critical loads in a manner similar to a double conversion UPS. Power to the critical loads can be provided by either direct pass through of grid power or directly from an external battery pack or the microturbine generator.

For simplicity, a lower-case x denotes a character that will vary with configurations and certifications. Not all combinations of configurations and certifications are available. Consult your local Capstone Sales representative for available catalog numbers. (2) Capstone microturbine models are generally designated by their fuel type. Refer to Capstone Fuel Requirements Technical Reference (410002) for additional information regarding these fuel types. (3) Type B and other sour fuels utilizing the HRM accessory must have a stainless steel (SS) core. (4) CE certified microturbines comply with VDE rule VDE-AR-N 4105: 2011-08, a Grid Interconnect regulation for power generation systems. This regulation is applicable for connection to a low voltage grid, which is defined as a 3-phase grid network with a nominal voltage less than 1 KV. (5) The use of Low Pressure Natural Gas (LPNG) with the C65 microturbine requires the Capstone GasPack accessory. The direct current (DC) version of the GasPack utilizes power directly from a microturbine, reducing overall electrical efficiency and potentially reducing the power available for external use. Refer to the GasPack Technical Reference (410058) for additional information. (6) New York City (Microturbine Rule 50) versions include a fuel regulator inside the microturbine enclosure. Low Pressure Natural Gas (LPNG) applications will require the New York version of the GasPack accessory. (7) Microturbine operational envelope is limited when operating in Stand Alone mode on Type B fuels. Refer to section Stand Alone Operation with Type-B Fuels on page 14. (8) The copper core HRM can only be used for liquid fuels with ultra low sulfur content. Refer to Fuel Requirements Technical Reference (410002) for sulfur content limitations in liquid fuels. 460044 Rev D (May 2013) Page 5 of 15

Table 2 Notes: (1) Ratings are at full load power and ISO conditions with zero back pressure. Values do not include parasitic losses from any accessories. The nominal values contained in this table do not reflect tolerance ranges. Deviation from the nominal value can occur due to differences between microturbines, measurement inaccuracies, and other factors. (2) See Figure 1 through Figure 4 for nominal power and efficiency charts with typical unit-to-unit variation. (3) The ratio of Higher Heating Value (HHV) to Lower Heating Value (LHV) is assumed to be 1.1. (4) Onload fuel flows and cold starts can be up to two times higher than steady state values. (5) In Stand Alone mode, maximum output current value assumes linear load. (6) Software versions 5.40 and higher (gaseous fuels) and 2.20 and higher (liquid fuel) include VDE (European Electrical Interconnection Guidelines) and Power Factor (PF) functionality. These software versions meet VDE requirements for low voltage grid interconnection and allow for power factor control. Upgrades in the field require key code to enable functionality. (7) Refer to the Capstone Emissions Technical Reference (410065) for microturbine exhaust constituent information. (8) Exhaust temperature will be lower if recovering heat with a Heat Recovery Module. (9) For C65 versions that include the HRM, the minimum operating ambient temperature may be higher, depending on heat recovery fluid characteristics. For water, minimum ambient temperature is 1.7 C (35 F). (10) The electronics inlet air temperature must be within 2 C (3.6 F) of the engine inlet air temperature. (11) Microturbines covered by this product specification have no internal fuel heating. The minimum operating temperature may be higher due to the properties of the fuel. Proper operation may require a higher minimum ambient temperature to ensure that the fuel remains in an acceptable state/condition. Refer to Capstone Fuel Requirements Technical Reference (410002) for additional information. (12) Refer to the section Stand Alone Operation with Type B Fuels on page 14 for additional information. (13) The microturbine must be stored in a dry, climate controlled storage facility. For long term storage, refer to Microturbine Standard Maintenance Schedule (440000). (14) The overall acoustic emissions value represents an A weighted value at full rated microturbine output power taken at a distance of 10 m (33 ft). The overall value consists of an average of multiple sound pressure readings at specific locations around the microturbine at 10 m (33 ft) and is not necessarily a max value. On site sound levels can vary due to a variety of factors such as background noise, environmental conditions and reflective surfaces. The optional acoustic inlet hood kit can reduce acoustic emissions at the front of the microturbine by up to 5 dba. (15) Height dimensions are to the roof line. Exhaust outlet extends at least 0.18 m (7 in) above the roof line. (16) Depth includes 0.25 m (10 in) extension for the heat recovery module rain hood on ichp versions. 460044 Rev D (May 2013) Page 8 of 15

(3) The ratio of Higher Heating Value (HHV) to Lower Heating Value (LHV) is assumed to be 1.1. (4) Onload fuel flows and cold starts can be up to two times higher than the steady state values. (5) The minimum fuel temperature depends on fuel type. Unless stated otherwise, for gaseous fuels, the minimum fuel temperature is 0 C (32 F), or 10 C (18 F) above the saturation temperature of the fuel at the operating pressure, whichever is higher. For liquid fuels, the minimum temperature 10 C (18 F) above the cloud point, or as required to satisfy the microturbine viscosity requirements, whichever is higher. (6) Minimum power output is 35 kw for these fuels when operating in Grid Connect mode. Additional fuel gas conditioning is required. Consult Capstone for specific application guidance. (7) As defined in ASTM D1835 for Special Duty Propane (HD-5). This fuel must be supplied to the microturbine fuel inlet as an unsaturated vapor. (8) The allowable liquid fuels are diesel fuels, kerosene, JP-8, and JP-5 per the liquid fuel specifications listed in the Fuel Requirements Technical Reference (410002). 460044 Rev D (May 2013) Page 9 of 15
5. Integrated Heat Recovery C65 microturbines incorporating an integrated Heat Recovery Module (HRM) are considered ichp versions of the microturbine. When operating in heat recovery mode, the ichp microturbine can recover portions of the exhaust energy to heat water passing through the HRM s heat exchanger core. In such instances, the amount of heat recovered will vary with several parameters, including the load of the microturbine, the flow rate of the water, and the temperature of the water at the inlet to the HRM. Table 4 illustrates the potential heat recovery of an ichp microturbine operating in full heat recovery mode for inlet water at various temperatures. Note that the minimum heat recovery for an ichp microturbine in full bypass mode is 3 kw th (10,000 Btu/hr). Table 4.

6. Performance Derating Microturbine performance, like all gas turbine technology, is affected by intake air mass density. The performance ratings listed above are at full load power at ISO (International Organization for Standardization) conditions. ISO conditions are defined as 15 C (59 F), 60% relative humidity, and sea level pressure of 101.3 kpa (14.696 psia). Performance derating may occur at ambient temperatures and elevations above ISO conditions. Other derating factors include air inlet pressure drop (e.g. air inlet ducting), back pressure, and system parasitic loads (e.g. fuel gas compressor, battery charging). The microturbine nominal net power rating and minimum/maximum nominal net power output versus ambient temperature is provided below for all applicable microturbine configurations. Likewise, the minimum and maximum nominal net efficiency versus ambient temperature is also provided. Note that the following figures show typical curves at sea level with no external parasitic loads, no inlet air restrictions, no exhaust back pressure, and the HRM (if installed) in full bypass mode. 70 Nominal Net Power vs. Ambient Temperature at Sea Level 60 2 kw 3 kw 50 3 kw Power (kw) 40 30 20 Nominal Min/Max 10 0 0 10 20 30 40 50 60 70 80 90 100 110 120 130 Ambient Temperature ( F) Figure 1.

7. Stand Alone Operation with Type B Fuels Capstone microturbines intended for Stand Alone operation and using Type B fuels (which are typical of anaerobic digester gas) have a limited ambient operational envelope. This operational envelope is restricted to the ambient temperature and altitude ranges shown in the shaded area of Figure 5. 125 122 100 95 Ambient Temperature ( F) 75 50 25 0 0 1000 2000 3000 4000 5000 Altitude (Feet) 6000 Figure 5.
