### [Matra] **Babcock -**  **Hitachi	wins €40m	extension	order	for	Hungary's	Matra**  **power	plant** 05/19/2005 19 May 20 05 - Babcock- Hitachi Europe (BHE) has received the order to extend the Matra lignite -fired power plant from Matra Kraftwerk AG, with head offices in Visonta, Hungary. The order is worth around €40m ($50.6m). BHE will be supplying two turnkey gas turbine sy stems. This will raise the capacity of the Matra power plant by 82 MW. Currently five lignite -fired units at Matra generate electricity; total capacity is in the order of 836 MW. The power plant lies at the foot of the Matra mountains near Gyöngyös, 100 km north - east of Budapest. The main equipments of both systems are two Hitachi H - 25 gas turbines/generator sets, which will be supplied by Hitachi, Ltd. The order also includes concept and final planning, supply and erection of the components, quality assurance management and system commissioning. For Klaus - Dieter Rennert, Chief Operating Officer of the BHE board of directors, "the contract award reflects well on the competitiveness of the Hitachi gas turbines in the wake of operating condition optimiza tion in European power plants by experienced Oberhausen BHE specialists." Rennert went on to say that this order was a good example of the excellent cooperation with the Hitachi group to provide an integrated solution for customer. "Our knowledge of custom er needs in Europe is of enormous help," says the managing director, "in getting across the product benefits of technology to the customer." Apart from a greater capacity, the two upstream systems starting commercial operations at the end of 2006 and the start of 2007 provide Matra Kraftwerk AG with a further advantage. There will be a substantial increase in controllability of the power plants - plant that generate electricity for base load requirements. Consequently, the operator can react considerably mor e flexibly to electricity market demands. And there is also something positive for the environment: both systems will lower specific CO2 emissions of the two lignite -fired units by some 10 per cent.

### [GE] **GE	Supplies	New	Turbines,	Unveils	New	Retrofit	Technologies	that Increase	Plant	Capacity	and	Efficiency**  General Electric (NYSE: GE) is deploying gas turbines at power plants in the U.S. and Saudi Arabia, and is also introducing new equipment that can be used to retrofit existing plants, driving up capacity and efficiency at those existing facilities. GE unveiled the technologies in a Dec. 9 session with the media at PennWell’s annual Power Generation Week conference in Orlando. In the U.S., GE will supply two of its highly efficient and flexible 7F.05 gas turbines to Calpine Corp. for the York 2 Energy Center, a nominal 760 - MW, dual -fuel combined cycle plant near York, Pa. That project is adjacent to Calpine’s existing York Energy Center. The turbines are to be delivered to the site in December 2015. These turbines will use GE’s Dry Lower NOx 2.6+ dual -fuel combustion system, which reduces NOx emissions to as low p ast 9 parts per million during gas -fired operations without using water injection technology. The turbines will also be able to operate on low - sulfur diesel fuel. In Saudi Arabia, the first four of GE’s 7F.05 gas turbines at Saudi Electric Co.’s Power Plan t 12 have reached commercial operation, with another four to follow. All eight units at PP12 should be operating commercially in combined - cycle mode by early 2015, delivering nearly 2,000 MW. PP12 is part of Saudi Arabia’s plan to add 33 GW of power capaci ty by 2020. The eight units at PP12 are the first of 20 GE 7F.05 turbines to be delivered, with another 12 turbines for PP13 and PP14 to be delivered in late 2014 and early 2015. Two new breakthrough technologies that GE announced for its 7F turbines - whi ch can be built as part of new installations and retrofit on older ones – are the Dry Low NOx (DLN) 2.6+ Combustion and Advanced Compressor upgrades. These are the latest additions to GE’s Power FlexEfficiency portfolio of upgrade solutions. Said Paul McEl hinney, GE’s president and CEO of Power Generation Services: “These solutions will provide our customers with the operational flexibility to quickly respond as their needs evolve over time.” The DLN 2.6+ solution adds fuel flexibility, allowing burns of up to 25 percent ethane or propane from shale gas, along with regular natural gas. The system can also handle up to 20 percent hydrogen. The first order for this upgrade system has been placed with an unnamed Midwest power plant. The technology also allows reductions of NOx emissions to as low as 5 ppm. It can be combined with GE’s OpFlex software to further reduce emissions.

Operated by PGE Elektrownia Belchatow (PGE), it is the biggest lignite -fired power plant in Europe. The plant was commissioned in 1988 and currently accounts for 20% of the Polish power marke t. In January 2011, PGE commissioned the 13th unit with a capacity of 858MW. The new unit has the highest efficiency of 41% and conforms to European standards on green house gas emissions. The generator was commissioned in September 2011. "Prior to the exp ansion, the Belchatów plant had 12 units of 360MW each." Retrofit of the existing units is also underway to increase the design life of the plant by 25 years. Plant make - up Prior to the expansion, the Belchatów plant had 12 units of 360MW each. All of the units are equipped with a BB - 1150 boiler, an 18K360 turbine and a GTHW - 360 generator. Coal is supplied to the plant from a nearby coal mine through conveyor belts. Plant details With a heat capacity of 750Gcal/h and performance rating of 1,150t/h, the boil ers have spirally wound furnace walls and are suspended on a grate carrier supported by four pillars. Design of the boiler features a low load circulation system. Coal is fed into the combustion chamber through a scraper and belt feeders. Eight mazut burne rs are used to light the coal with air supplied by two air fans and exhaust fans. The combustion chamber of the boiler features two circulating pumps. Superheated steam generated by the boiler is sent to single shaft turbines. The turbines feature four con trol valves and are rated at 370MW with a turnover of 3,000rpm. A programme to modernise the turbines was carried out between 1997 and 2004, which increased the capacity by 10MW and reduced heat energy consumption by 210KJ/kWh. A synchronous generator with a bipolar structure and cylindrical rotor generates electricity. Development

Page **13** of **2 4**  In April 2009, PGE launched a retrofit programme for unit 6 of the power plant to increase the unit's output to 390MW - 400MW. The upgrade programme will retrofit the turbines and auxiliaries, electro - hydraulic control system and instrumentation and control (I&C) equipment. The boiler firing system will be upgraded to reduce emissions to 200mg/Nm3 for CO and NOx. A new distributed control system, eight new pulverised coal burners an d a flue gas heat exchanger will also be added to the unit. In 2010, another retrofit project for units 7 to 12 was launched to increase their capacity by 20MW each. High pressure and intermediate pressure turbines and auxiliaries, bypass systems and I&C e quipment will be installed as part of the retrofit. New electrostatic precipitators will also be installed to reduce emission levels to 50mg/Nm3. The contract for the retrofit programme was awarded to Alstom in March 2011. "Alstom was awarded a €160m contract in 2009 to retrofit the unit 6." IFS implemented an ERP system at the plant, which helped in quick access to operational data and enhanced document management. Emerson was contracted in November 2009 to carry out the modernisation of units 5 and 6 . The company had earlier won a contract to automate units 3 and 4. Under the 2009 contract, Emerson installed its PlantWeb digital plant architecture and Ovation expert control system to upgrade the units' I&C. Emerson will also install 110 Rosemount wire less temperature transmitters on the boilers to monitor temperatures. The project will help in reducing the CO2 emissions to 200mg/m3 and the NOx emissions to 200mg/m3. In February 2011, Emerson won another contract worth $95m to automate units 7 to 12. Th e units 7 and 8 of the plant are planned to be shut down in January 2012 and June 2012 respectively for modernisation. These units will be recommissioned in 2013. Contractors Rafako constructed the boilers for the plant with technology licensed from Sulzer and EVT. The turbines were manufactured by Zamech under a license from Brown Boveri & Cie (now part of ABB). The generators were manufactured by Dolmel (now part of Alstom Power). Hayward Tyler supplied the circulating pumps. In 2008, Hempel provided its high quality protective coatings for the cool water pipelines of the plant. Babcock Borsig Service was awarded a contract in 2009 to supply flue gas displacement system for units 5 and 6.

PERI supplied a falsework combination consisting of ST 100 stacking towers and MULTIPROP aluminium slab props for the 13th unit. ME Construct was also involved in the construction of the unit. Alstom was awarded a €160m contract in 2009 to retrofit the unit 6. In October 2010, Alstom was awarded another retrofit contract worth €140m for units 7 to 12. Pollution issues The Belchatów plant is considered to be one of the biggest producers of greenhouse gas emissions in the EU, emitting about 30mt/y of CO2. To reduce the emissions from the plant, PGE has launched a two phase programme to build carbon capture plants (CCP). In the first phase, a pilot CCP will be built at unit 12. The pilot CCP will use Alstom's Advanced Amine Process with amine solvent supplie d by Dow Chemical. It will capture about 100,000t/y of CO2. In the second phase, a bigger plant will be built to capture carbon emissions from the new 858MW unit. The new plant will capture 1.8mt/y of CO2 and is expected to be operational by 2015. The proj ect will require an investment of $776m and has received a €180m grant from the European Investment Bank in May 2010. Source: http://www.power-technology.com/projects/belchatow - plant/ 

### [Bonanza] **Deseret	Power	Electric	Cooperative,	Bonanza	Power	Plant,	Uintah and	Ouray	Reservation,	Uintah	County,	Utah:	Statement	of	Basis**  [Excerpt from text follows ] We are especially interested in how the State made the determination in 1998 that the “ruggedized rotor” project was only a synthetic minor modification and did not trigger PSD review. The 1998 Approval Order and supporting documentation state that boiler heat input was increased from 4381 MMBtu/hr to 4578 MMBtu/hr, and that approximately 20 MW from the upgrade will result from an increase in steam flow produced by the boiler. To date, the boiler has not been operated at its peak potential due to limitation s of steam flow at the existing Turbine Generator. The Project will allow the Turbine Generator to accept all of the steam flow the Boiler is capable of producing. While the Ruggedized Rotor by itself will not result in any change to Bonanza 1’s emissions, the increased capacity of the Turbine Generator to handle the Boiler’s peak capacity will increase the Bonanza plant’s overall potential to emit (PTE). To our knowledge, we were never advised of, nor involved in, that action. We do not understand how thi s boiler could be up - rated from 440 MW to 500 MW without an increase in actual emissions, unless Deseret acted to offset the increase in actual emissions by some physical change or change in its method of operation. We are concerned that the reductions in allowable lb/mmbtu emission rates mentioned in the “Permitting History” do not reflect a reduction in actual emissions and what we are seeing are merely “paper” reductions.

### [Hawthorne] **Completing	a	550MW	Pulverized	Coal	Fired	Utility	Pro ject	on	an**  **Accelerated	Schedule** In February 1999, a natural gas explosion destroyed a 500MW coal -fired utility boiler at Kansas City Power & Light Company’s Hawthorn Generating Station. The loss of this critical base - load unit left Kansas City Power & Ligh t (KCPL) with a difficult decision — replace the coal -fired boiler, or convert to gas -fired combined cycle. Although most of KCPL’s power generating plants burn coal, Unit #5 was the only coal -fired unit at Hawthorn Station. Ultimately, KCPL decided to repla ce the destroyed steam generator with another coal -fired unit, and repower the existing turbine/generator equipment. By August, 1999 the utility, Burns & McDonnell and Babcock & Wilcox had a plan in place to build a new, 550MW pulverized coal -fired facility and have it producing power and revenue by June 2001.

### [Intermountain] **THE	ECONOMIC	AND	FISCAL	IMPACTS OF	EXPANDING	THE**  **INT ERMOUNTAIN**  **POWER	PROJECT** [Excerpt from text follows] Construction of IPP began in October 1981. The initial concept for the $5.4 billion project was to build four 750 - MW coal -fired units in Lynndyl, Utah, a site located approximately 100 miles southwest of Salt Lake City. However, by the time the first two units began operating in 1986 and 1987, the project had beendownsized to two 750 - MW units leaving room on the site for additional expansion. Since the mid 1980s, the gross capacity of the existing units h as been upgraded to 1,900 megawatts.

Page **16** of **24** Alstom in 2008 included the retrofit and upgrade of the complete steam turbine island and the associated balance of plant at unit 8 of the plant to match the new steam data following the installation of a gas turbine from another vendor. The project started in April 2009 and has been successfully completed with the commissioning of the retrofitted unit 8 in July this year. It has contributed to the increased output of unit 8 from 215 MW to above 400 MW and the jump in efficiency by more than 20 % - from 36 % to 57 %. The efficiency increase also results in a substantial reduction of CO2 emissions from the plant. This project was a brown field investment, whereby the steam turbine island unit no 8 was modernised by using the power plant’s existing infrastructure. The six conventional type 215 MW steam turbines at the plant including the related condensers and feedwater heaters were originally supplied by Alstom companies. Within the scope of this project, Alstom replaced the high - pressure steam turb ine in unit 8 with a high performance new module and upgraded the medium and low - pressure cylinders, the generator and the balance of plant – thus enabling the turbo group and its auxiliaries to operate in a highly efficient combined cycle mode. László De ák, Country President of Alstom Hungary said, “Alstom is proud to have been a part of the rehabilitation of Hungary’s biggest power plant. Repowering is a special engineering application that requires significant engineering capabilities to synchronise the existing equipments with the new ones. Alstom has significant experience in the field that has allowed us to complete this project timely and contribute to the increase in output and efficiency. This upgrade will be a key example of the services we can pr ovide to upgrade the power generation fleet in Hungary.” Dunamenti is located near Budapest and is one of the country’s biggest power plants with 6 x 215 MW steam turbine units and two other combined cycle and cogeneration units. The plant has a total capa city of 1736 MW. The retrofit of unit 8 labelled ‘G3’ was part of a bigger rehabilitation programme undertaken by Gaz de France Suez to reduce the environmental impacts of their plant.

### [Korai] **Maharashtra	all	set	to	upgr ade	old	power	sets**  Monday, 27 July 2015 - 6:50am IST | Place: Mumbai | Agency: dna | From the print edition Move will help increase generation capacity at lower costs than setting up new projects To boost electricity generation and increase the efficiencie s of its thermal power units, the state power generation utility is planning to modernise its old sets. This will help add capacity at lower costs than setting up new projects and generate more power from lesser quantity of coal. A large number of the Maha rashtra State Power Generation Company Limited's (MahaGenco) thermal power sets are old and antiquated. Of the 29 units in service, 11 are over 30 years old and 6 are aged above 25 years. All these units have an installed capacity of 210 MW each. Of the Ma haGenco's 7,980 MW installed coal - based capacity, almost half (3,570 MW) is in these antiquated units, which have lower generation efficiencies. The modernisation project, which will add capacity and expand efficiency in generation at a cost lower than tha t of setting up a new unit, has been launched at the Koradi power plant. It will later be expanded to four more units, namely one set each at Nashik, Bhusawal, Chandrapur and Parli, based on this experience. "We have undertaken the renovation and modernisation of one 210 MW unit at Koradi. Here, the vital parts of the boiler, turbine and generator and the coal handling system will be changed and modified to increase the operational efficiency. However, the foundation and the boiler's body will rema in as it is. This will increase the installed capacity of this unit to around 228 to 230 MW from the present 210 MW. Since these units are old, they have a plant load factor of only 50 to 52% and this renovation will bring it up to 80 to 85%. This means we can generate more power with lesser coal," said a senior MahaGenco official. The Koradi project was launched last year and the actual work has begun this month. It is expected to be completed by March 2016. The state will get funds from the World Bank and infuse the remaining amount as equity for the project, the official stated. The official added that this modernisation cost just around Rs2 crore per MW as compared to the costs of setting up a new coal - based thermal power set at around Rs6 to 7 crore per MW.

Page **18** of **24** "We are undertaking work on 3,230 MW new capacity, including three 660 MW sets at Koradi and two 1,000 MW units at Chandrapur. The Koradi units are supercritical sets, which means they have less variable costs. This additional capacity, which will be on line by March 2016, will enable us to shut down old units for renovation and modernisation," the official said. MahaGenco has 7,980MW of its 11,237MW installed conventional energy capacity in coal, with the remaining comprising of gas (672MW) and hydro power (2,585MW). The average weighted average cost of power generated by the utility is about Rs3.28 per unit, with that of thermal being around Rs3.70 per unit.

### [Polaneic] **Alstom	signs	modernization	contract	worth	approximately	65 million	euros	for	the	Polaneic	Power	Plant	in	Poland**  07/05/2012 Alst om, the global leader in steam turbine retrofitting, today announced that it has signed a contract worth approximately €65 million with GDF Suez Energia Polska S.A., which owns and operates Poland’s Polaniec power plant for modernisation of six units (unit s 2 - 7) of the power plant. The contract also includes the option of retrofitting an additional unit (unit 1) of the power plant. Połaniec Power Station is a coal -fired power station near Połaniec in Świętokrzyskie Voivodeship, Poland. It consists of eight units each with a generation capacity of 225 MW. The first unit was commissioned in 1979 and the last in 1983. Between 1992 - 1995, the low pressure (LP) steam turbines of all the units were retrofitted. Under the terms of the contract , Alstom will engineer, deliver and commission new high pressure (HP) and intermediate pressure (IP) steam turbines. The scope also covers main overhaul of LP parts, the modernisation of the turbine auxiliary systems. The first modernised turbine will be ready for operation in May 2013 and the final one will be handed over for commercial operation in December 2014. Decision about the modernisation of unit 1 will be taken before 2014. The modernisation will improve the units’ availability and reliability and will extend the plant ’s lifetime by an additional 25 years. On average each unit will generate an output in excess of 240 MW, following the modernisation. Increase in unit efficiency will also significantly reduce carbon dioxide emissions from the facility. The modernisation project will be fully executed by Alstom’s Thermal Services organisation in Poland. The majority of the steam turbine will be manufactured at Alstom’s steam turbine factory in Elblag. The contract represents a further consolidation of Alstom’s retrofit exp erience in Poland and follows orders worth approximately €15 million to upgrade the Kozienice and Lodz coal -fired power plants, signed earlier in March this year.

### [ **Little	Barford	Powe r	Station** **]** Little Barford is a combined cycle gas turbine power station located south of St Neots on the Cambridgeshire - Bedfordshire border on the site of a former coal fired power station. Little Barford began operation in 1996 and had a generating capaci ty of 680MW enough to meet the electricity demands of over half a million households. The power station has one generating module, consisting of two gas turbines and one steam turbine. The Station also has an open cycle gas turbine providing black start ca pability to the site. Earlier this year the station finished a year long £100 million investment to upgrade the gas turbines and other areas of the power station. It is envisaged that the upgrade will extend the life of the plant to around 2025, and includ ed replacing the two gas turbines and the control system alongside a full upgrade of the boilers, steam turbines, generators and other plant components. The Power Station has a new capacity of 720MW, equivalent to an additional 30,000 homes that can now be powered by the plant. Emissions of nitrogen oxides (NOx) have been reduced by 40% which will enable the station to meet the stricter environmental limits being implemented in the UK on power generators. The increased fuel efficiency of the plant will save the equivalent of 118,000 tonnes of carbon dioxide (CO2) each year. When operating normally the power station can provide all its own works power. However when the power station is shut down it then usually requires electricity from the National Grid to start up. In the event of a major failure of the national grid distribution system, the black start turbine will allow the power station to start up without taking electricity from the National Grid. The main fuel used to generate electricity at Little Barford Power Station is natural gas, however the station also has the ability to use gas oil as a back up fuel.
