Vernon, CA 90058 Subject: City of Vernon, Extension Dear Ramon, We appreciate the continued confidence in ALSTOM Power and we are looking forward to be working with you in this extended scope, forming power island package together with the gas turbines. We understand the urgency in getting the documentation required for your permitting process in place, and hence, ALSTOM Power is committed to provide the information related to our equipment by mid September for this purpose. Please note that this information will be preliminary since some information and drawings might change during the project phase, During our meeting in Denver we discussed the possibility of issuing a purchase order for this information. Since we understand that speed is critical here, we think that the legalities of such a contract might slow down this process and also complicate this issue more than necessary, and therefore, we will take on this responsibility without a formal purchase order. Please find enclosed the list of information required for the permitting, as provided in the meeting in Denver. We've marked the information we will submit and assume that others will supply the balance of information. Further, ALSTOM Power recognize the value and the convenience for the City of Vernon to get a total power plant performance guarantee, with associated project management / administration and heat balance engineering, optimization and coordination of the total ALSTOM Power scope. Therefore, ALSTOM Power will provide an overall wrap around the performance guarantee document associated with the extension, i.e. the steam turbine and the HRSGs, and the original base scope, i.e. the gas turbines. This wrap around responsibility and coordinating effort will be included in the price for the equipment. ALSTOM Power Inc. 10730 Telge Road Houston, TX 77095-5002, U.S.A.

GENERAL The purpose of the Turbine Protection System is to protect the installation when abnormal operation conditions occur making a continued safe operation impossible. The Turbine Protection System comprises two separate parts, one electrical and one hydraulic part. The electrical section consists of a digital controller, with corresponding power -supply and 1/0 modules, and three redundant speed monitoring channels. The hydraulic part consists of a high pressure hydraulic oil system, powered by two redundant pumps. The interaction between the two sections is the electro- hydraulic solenoids valves. The Turbine is tripped when the hydraulic trip oil is a drained by de -energizing the solenoid valves, causing the servos to quick -close s the steam valves.

In an overspeed situation each speed monitoring channel will de -activate its trip solenoid valve, causing it to open. The nominal set value of the overspeed tripping device is 110% of nominal speed. Testing of overspeed trips is carried out by increasing the actual speed to the trip levels. Each speed monitoring channel can be tested on line, simulating an overspeed signal from the pick-up by adding a virtual additional 10% speed to the signal. The corresponding trip solenoid valve will then be de -energized and indicate correct function. The speed monitoring channels supervise the speed pick-ups and give an alarm in case of faulty pick-up.

The Turbine Controller (governor) is capable of controlling speed and output of the turboset plus process parameters such as pressure and temperature in adjoining systems. The Turbine Controller (governor) comprises of two separate parts, one electrical and one hydraulic part.

The turbine governor Controller Section includes a number of controllers and limiters, each dedicated to a defined function, for example frequency/output control, inlet steam pressure control, load limitation, etc. A controller, as well as a limiter, compares a set (desired) parameter value with the actual measured value. If a deviation exists, the controller/limiter produces a signal causing the controlled valve to move in the direction required to eliminate the deviation. For a controller, the set value is generated within a set value generator. ALSTOM Pawx Sweden AS Based on : 4400.06E:1 Industtal Turbt�e SepneM Page A LSTOM Control System. 3 (6) AC110, Turbine Controller (Governor) STFrwnber Ethan Doc Ksd 4400-06E 2 SD The set value generator is controlled by an external set value sent from the Operator Station (by the operator) via the turbine automation node. A limiter normally has a fixed set value and thus no set value generator. All controllers and limiters, are of the proportional -integrating type, i.e. PI controllers. The typical characteristic of a PI controller is the lack of steady state control deviation, i.e. a very accurate control. The different controllers and limiters interact through a number of selectors. The selectors are either of the Minimum Selection Type - i.e. a selector allowing the lowest of two or more signals to pass - or the Maximum Selection Type - i.e. a selector allowing the highest of two or more signals to pass. Thus, changeover from one controller function to another is accomplished by increasing or decreasing the set value of one controller or another. This principle eliminates the need for controller function selector switches and also results in bumples transfer from one mode of control to another. The valve position controllers, one for each governing valve, are PDP controllers receiving the output from the controller section as set value and the actual governing valve position as feedback. The position is measured with an electronic � e �a transducer. The valve position controller output is fed as a current to the electro- ► i E hydraulic converter in the governing valve servo motor. Here, the. signal is converted to an oil flow proportional to the current, an oil flow which will : m position the governing valve in the position required by the limiter or controller in action. In the event of loss of control signal, a mechanical bias in the electro hydraulic converter will cause the control valve to close. The valve will also close if the valve position feedback is lost. Below follow a short description of the most common controllers and limiters (base configuration): Run-up Controller The run-up controller is a speed controller used for running up the turbine from standstill to nominal speed. The controller can either be run in automatic mode or manually. Frequency/Output Controller The frequency/output controller will maintain the turbine at a desired speed when operating in isolation from an external grid or at a desired output when synchronized to an external grid ALSTOM Power Sweden AS k Based on: M00�06E:1 odusl" Twbhe Segm d i� A LST1M Control System AC110, Turbine Controller (Governor) Pape 4 (6) ST14martxr Edkim D= I*W 4400-06E 2 SD Step/Gradient Limiter, Loading The step/gradient limiter will prevent too rapid opening of the governing valves, thereby reducing the thermal stress of the turbine. The two fixed set values for step and gradient, respectively, are preset according to limitations valid for the turbine in a hot state. Minimum Output Limiter The minimum output limiter is connected to maximum selectors in such a way, that it overrides other controllers and limiters (in all control mode) capable of reducing the steam flow below min. steam flow through the turbine. Minimum Boiler Pressure Gradient Limiter The Minimum Inlet Pressure Gradient Limiter will prevent the turbine from demanding more steam than is produced in the boiler, thereby causing a rapid drop in live steam pressure, temperature and/or water carry-over from the boiler to the Turbine. By throttling the Turbine Main inlet valve(s) the boiler pressure will be limited to an acceptable decrease rate. $am The Minimum Inlet Pressure Gradient Limiter uses the actual inlet live steam The pressure value, connecting it to a ramp function and creating a new set value. maximum rate of change of the set value at decreasing inlet pressure is set to ` 30/o/min of nominal turbine inlet pressure. The inlet pressure set value has, a turbine inlet minimum value limit, normally set to 35% of the nominal pressure. The number of controllers/limiters varies of course depending on process configuration/requirements.

GENERAL The purpose of the Turbine Controller (governor) is to control the steam flow rate through the turbine and, -if applicable, through controlled extractions. The Turbine Controller (governor) is capable of controlling speed and output of the turboset plus process parameters such as pressure and temperature in adjoining systems. The Turbine Controller (governor) comprises of two separate parts, one electrical and one hydraulic part. The electrical section consists of a digital controller with corresponding power supply and VO modules. The hydraulic part consists of a high pressure hydraulic oil system, powered by two redundant pumps. The interaction between the two sections are the electro- hydraulic converters (servos) that convert the current loops to a hydraulic oil 1 flow. in document. The hydraulic oil system is described separate a a 2. CONTROL PHILOSOPHY 2.1 Hardware s 2 The Turbine Controller is based on the use of a programmable controller AC110 is of ABB Advant® family.

The turbine governor Controller Section includes a number of controllers and limiters, each dedicated to a defined function, for example frequency/output control, inlet steam pressure control, load limitation, etc. A controller, as well as a limiter, compares a set (desired) parameter value with the actual measured value. If a deviation exists, the controller/limiter produces a signal causing the controlled valve to move in the direction required to eliminate the deviation. For a controller, the set value is generated within a set value generator. ALSTOM Poway Sweden AS Based on:4400-WEI MduSW TWMW S"RWM G ALSTOM Control System Papa 3 (6) AC110, Turbine Controller (Governor) STI-txxo6er Edson Doc.IGid 4400-06E 2 SD - The set value generator is controlled by an external set value sent from the Operator Station (by the operator) via the turbine automation node. A limiter normally has a fixed set value and thus no set value generator. All controllers and limiters, are of the proportional -integrating type, Le. PI controllers. The typical characteristic of a PI controller is the lack of steady state control deviation, i.e. a very accurate control. The different controllers and limiters interact through a number of selectors. The selectors are either of the Minimum Selection Type - i.e. a selector allowing the lowest of two or more signals to pass - or the Maximum Selection Type - i.e. a selector allowing the highest of two or more signals to pass. Thus, changeover from one controller function to another is accomplished by increasing or decreasing the set value of one controller or another. This principle eliminates the need for controller function selector switches and also results in bumples transfer from one mode of control to another. The valve position controllers, one for each governing valve, are PDP controllers sreceiving the output from the controller section as set value and the actual " governing valve position as feedback. The position is measured with an electronic transducer. The valve position controller output is fed as a current to the electro- is s hydraulic converter in the governing valve servo motor. Here, the signal $ converted to an oil flow proportional to the current, an oil flow which will position the governing valve in the position required by the limiter or controller in action. In the event of loss of control signal, a mechanical bias in the electro hydraulic converter will cause the control valve to close. The valve will also close if the valve position feedback is lost. Below follow a short description of the most common controllers and limiters (base configuration): A Rim -up Controller The run-up controller is a speed controller used for running up the turbine from standstill to nominal speed. The controller can either be run in automatic mode or manually. Frequency/Output Controller The frequency/output controller will maintain the turbine at a desired speed when operating in isolation from an external grid or at a desired output when synchronized to an external grid ALSTOMPMW Sweden AS S1nawMw Tuibhe sep aved on :,,00-06EA ALSTOM Control System AC110, Turbine Controller (Governor) 4 (6) STI-nub Edition D= Wnd 4400-06E 2 SD Step/Gradient Limiter, Loading The step/gradient limiter will prevent too rapid opening of the governing valves, thereby reducing the thermal stress of the turbine. The two fixed set values for step and gradient, respectively, are preset according to limitations valid for the turbine in a hot state. Minimum Output Limiter The minimum output limiter is connected to maximum selectors in such a way, that it overrides other controllers and limiters (in all control mode) capable of reducing the steam flow below min. steam flow through the turbine. Minimum Boiler Pressure Gradient Limiter The Minimum Inlet Pressure Gradient Limiter will prevent the turbine from demanding more steam than is produced in the boiler, thereby causing a rapid drop in live steam pressure, temperature and/or water carry-over from the boiler to the Turbine. sBy throttling the Turbine Main inlet valve(s) the boiler pressure will be limited to an acceptable decrease rate. The Minimum Inlet Pressure Gradient Limiter uses the actual inlet live steam The pressure value, connecting it to a ramp function and creating a new set value. maximum rate of change of the set value at decreasing inlet pressure is set to 2 301o/min of nominal turbine inlet pressure. The inlet pressure set value has a minimum value limit, normally set to 35% of the nominal turbine inlet pressure. lilt, i The number of controllers/limiters varies of course depending on process € configuration/requirements.

The transducers measure the vibrations of the shaft relative to the bearing housing. The turbine modules as well as the generator are equipped with two transducers at each bearing. Gears are equipped with one accelerometer. Further, there is a Key Phasor®i to determine the shaft angle on each of the turbine shafts. A high vibration level on any of the above transducers will cause an alarm. An excessively high vibration level on any of the transducers will trip the unit. Vibration and Shaft Position Measurement Vibrations and shaft positions are measured as peak -to -peak amplitude expressed in microns or mils. Measuring Equipment The proximity transducer consists of a proximity probe and a preamplifier or signal converter, (Proximitor®"). The proximity transducer works on the eddy current principal. A radio frequency is generated within the proximitor and sent via a special cable to the probe where it is radiated into the observed material, setting up eddy currents. The return signal is then fed back to the proximitor and the loss of energy is measured. The same type of proximity probe and proximitor is also used as a key phasor and for shaft position detection. The proximitor is mounted in a junction box locally on the unit. The input signal from the proximity probe is linearised and fed via conventional shielded cabling to the monitor mounted in the turbine control cubicle or separately in the control room. proximotore and Key phasor® are registrated trade marks of the Bently Nevada Corporation ALSTOM Power Sweden AB kuk a" Turbine Sepnent Based on: 4 WISE : 1 Page CONTROLL SYSTEM 44 2 (3) ALSTOM Shaft Vibration and Position Monitoring STHiunber Edson Ooc. Kind 4400-15E 2 SD For the gear the vibration measurement is carried out by Acceleration Transducer System.The accelerometer uses a piezo-electric crystal situated between the accelerometer base and an inertial reference mass. When the accelerometer is mounted on the gear casing, machine vibration causes a compression or tension force to act on the crystal. The crystal, in turn, acts as a precision spring to oppose the compression or tension force. The crystal thus generates a displaced electric charge. An integral amplifier converts the charge to voltage.. The monitor will give an analogue output of the shaft vibration level to the turbine protection system, where the alarm and trip limits are programmed. The actual vibration levels are displayed on the screen of the operator's workstation.

The system thus prevents accumulation of water which could give rise to damageing water hammer, cause erosion or unforeseen steam flows when this water gets evaporated when the pressure decreases. Drain from pipes and valves, the turbine itself and associated apparatus are classified into two groups - external and internal drains - as shown in Fig.l and outlined in the text below. These two classes of drains must never be interconnected due to the risk of back flow of steam or drainage to the turbine. This is particularly important if for some reason the turbine is shut down for maintenance for a long period of time. On these occasions it must be possible to isolate the turbine completely from all external systems to be able to work with the turbine. Also if the turbine is shut down wet steam can cause severe corrosion to the turbine internals.

The internal drains are connected to the condenser or to a drain tank which in turn is connected to the condenser. The internal drains must not be connected to the atmosphere due to the risk of air leakage back through the turbine to the condenser during vacuum raising. Example of internal drains: • Lines between the governing valves and the turbine • Turbine casing drains • Interconnecting line between turbine modules I • Gland steam line downstream of an isolating valve • Gland steam condenser • Extraction lines which can not be pressurised when the turbine is shut down. • Condenser for steam driven ejector. i b � External drains ;< Lines that are connected to steam supplies, that might be pressurised when the turbine is F . shut down or at stand -still, must be drained externally away from the turbine and the condenser. Most commonly the external drains are connected to an atmospheric drain tank from fill. where the drain is dumped or pumped back into the condensate line. External drains must never be led to the drain tank for the internal drains. This could result in steam or water from this tank being forced backwards up into the turbine and causing severe corrosion to the turbine internals if the turbine is shut down for maintenance etc. Also it must be possible to isolate the turbine and condenser from external systems to be able to do maintenance on the turbine Example of external drains: • Emergency stop valve casing and live steam line up -stream the governing valves. • Gland seal line up -stream an isolating valve. • Auxiliary steam lines up -stream isolating valves. • The parts of extraction steam lines which might be pressurised when the turbine is shut down.

All lines carrying drainage to the tank must be installed with continuous slope to prevent water from accumulating in the lines during e.g. standstill and start-up. The drain tank must be connected to the condenser. The flash line from the drain tank to the condenser must be dimensioned so that the pressure drop is negligible also with all drains to the tank open. Otherwise there is a risk that pressure build-up in the tank might cause back -flow in some drains. Special attention must be paid to the pressure drop when automatic drain valves are used which remain open up to part load (about 15 0%). In the cases where the drain tank is situated so that it can not be drained to the condenser hotwell by a loop seal, the drainage must be pumped to the condenser. The tank must not be open to the atmosphere since it constitutes a part of the plant e subject to condenser vacuum. Additional cooling might be required in the tank to keep the steam temperature in the flash line to the condenser below the condenser design temperature.

Knd r. 0700-01E 3 SD Steam Purity Requirements for Turbine'Operation General Water and steam of sufficiently high quality are necessary for reducing the risk of corrosion and deposits in the boiler and turbine. This is achieved by using good make up and feed water treatment. Careful supervision of the feed water system and steam boiler is therefore very important, also for ensuring the reliability and availability of the turbine. The steam quality requirements are independent of the boiler pressure and temperature. The specified values must be maintained if the expectations of continuous, trouble -free operation of the turbine are to be met. To avoid deposits, it is particularly important to ensure that the contents of silica and alkali are sufficiently low. Deposits always result in reduced efficiency. In particularly adverse cases, deposits may also involve the risk of damage. In order to safeguard a sufficiently high quality of the water and steam, adequate a supervision must be provided. Continuous measurement of cation conductivity of the steam is a.minimum. requirement. Demands on the Turbine Steam tillThe specified values are the maximum values for continuous operation. Whenever s possible, the actual values should be lower than the specified values. The maximum fill g0 values may temporarily be exceeded during start-up and other transients. However, the be downward. The values for continuous operation must be trend of the values must achieved no later than 2 hours after hot start-up and 8 hours after cold start-up. The steam quality requirements serve as a basis for determining the guideline values for the feed water and boiler water. The guideline values for boiler water and feed water are given in "Guideline values for boiler water", and "Guideline values for feed water". C.

The steam can be contaminated by mechanical carry-over of boiler water, by the use of contaminated water for spray attemperation, or by the solubility of the impurities in the high pressure steam. In order to maintain an acceptable level of salt carry over, it is important to ensure that the water separators in the steam paths of the boiler are sufficiently effective, and that boiling -over, foaming and over -feeding of the boiler are avoided. � _ increasing boiler pressure. The The risk of mechanical carry-over increases with incr g € M solubility in steam is dependent not only the boiler pressure, but also on the boiler water m chemistry. f < Deposits E always result in impaired efficiency and, in adverse cases, may Deposits in the turbine al y p even cause damage. Deposits in the turbine may be soluble or insoluble in water or saturated steam. Sodium hydroxide is an example of a soluble salt. Sodium hydroxide should normally be limited to less than 1/10 of the total salt content of the boiler water. High contents of sodium hydroxide in the deposits in the turbine may cause corrosion. Typical water insoluble deposits include silica, copper oxides and iron oxides. The solubility of silica in steam is relatively high even at low pressures, and silica will be deposited in the low-pressure turbine if its content in the steam is in excess of 0.02 mg/kg. The concentration of silica in the feed water and boiler water must therefore be kept under control. Even temporary excursions beyond the specified maximum concentration in the steam may lead'to deposits in the turbine.

Kind 0700-01 E 3 SD Corrosion Corrosion attack may occur in the turbine if the steam contains corrosive salts or corrosive gases such as carbon dioxide. Hydrazine is often used for residual oxygen removal after mechanical deaeration. At high temperatures, hydrazine decomposes into nitrogen and ammonia. Ammonia may give rise to corrosion damage to copper -alloy condenser tubes. Sodium sulphite should not be used for residual oxygen removal at pressures above 35 bar, since it may decompose into aggressive sulphur compounds. Large quantities of bicarbonates can be prevented from entering the boiler by appropriate feed water treatment. These salts decompose to form, among others, carbon dioxide which is entrained by the steam and makes it corrosive. i; i During stoppages, the turbine should be kept dry in order to avoid shut -down o corrosion of the rotors and blades. GUIDELINE VALUES FOR BOILER WATER In order to meet the demands made on the steam, the feed water and boiler water must 62 bar, be treated. Demineralized water can always be used. At boiler pressures below g softened water (salt -containing water) can also be used as make-up water. Table 2 gives guideline values for boiler water originating from salt -containing and salt -free feed water. Boiler water from salt -containing feed water The guideline values should be adjusted on the basis of operating experience. Experience has shown that certain plants perform satisfactorily only when the actual values are substantially lower than the tabulated maximum values. The value of p-alkalinity is given only for guidance. The p-value is explained in Page 11, (Explanation of guideline values). Phosphate and sodium hydroxide, if any, are dosed into the boiler. The phosphate treatment removes the residual hardness and raises the pH. The sodium hydroxide only raises the pH. If sodium hydroxide is dosed, a very careful check must be kept on the excess sodium hydroxide.

Sodium The sodium content originates from additives, cooling water leakage, contaminated return condensate and problems in the regeneration of ion exchangers. It is important to keep a good check on the sodium.

The P-alkalinity is measured by means of a titration with standard acid solution in the presence of phenolphtalein PH The pH value is a factor which is decisive to corrosion in the water and steam systems. Solid alkalising agents (sodium phosphate, sodium hydroxide) and volatile alkalising agents (such as hydrazine and ammonia) are dosed in order to increase the pH. Phosphate Phosphates are dosed in order to raise the pH value and, if salt -containing feed water is employed, it binds the residual hardness. It is important to avoid over -dosing due to the risk of carry-over of sodium salts to the turbine. Oxygen The oxygen content should be maintained at the recommended values. Oxygen may otherwise cause corrosion problems. Content of organic substances The potassium permanganate consumption and TOC (Total Organic Carbon) are measures of the organic substances in the boiler water. The content of organic sub- stances should be kept as low as possible to avoid the risk of their decomposition to organic acids.
