[Arnot] Alstom signs power plant upgrade and retrof it contract with Eskom in South Africa 03/01/2012

Alstom has won a contract worth 110 million euros t o refurbish the 2,100 MW Arnot coal-fired power plant in South Africa, and increase its power outpu t by 300 MW to 2,400 MW. The plant is owned by state-owned utility company Eskom.

For each of Arnot’s six steam generating units, Als tom will carry out a complete retrofit for the high pressure and intermediate pressure steam turbines, a capacity upgrade of the low pressure steam turbine and the replacement and upgrade of associat ed turbine side pumps and auxiliaries. In addition, Alstom will carry out major upgrading works to the boiler plant, including supply of new pressure part components, new burners, and modification to other equipment such as the coal mills and classifiers,
fans and heaters.

The first unit is scheduled to be completed by Dece mber 2007 and the last unit by December 2010.

Alstom was able to offer Eskom an integrated plant retrofit approach for this complex power plant project, which encompasses many major generating pl ant components such as boilers and turbines. The Arnot capacity increase project (ACIP) is the first combined capacity increase and retrofit project in
South Africa.

Philippe Joubert, President of Alstom’s Power Turbo -Systems/Power Environment Sector, said: "This new contract represents a significant milestone in the historically strong relationship between Alstom and Eskom. This demonstrates our unique ability to offer an integrated solution involving all the majo r components of a retrofit project - boilers, steam t urbines...This solution allows us to offer Eskom a better competitiveness as well as an environmentall y friendly power plant."

Adding a much needed 300 MWe at South Africa’s Arno t coal fired power plant

As power stations built in the last thirty years ap proach the end of their design life, and the cost o f new capacity continues to increase – along with demands for improved efficiency and lower emissions - an integrated approach to retrofit looks increasingly compelling. The ambitious upgrade project currently underway at the Arnot coal fired plant in South Afr ica – which will result in an uprate from 6 x 350 M We to 6 x 400 MWe and a life extension of 20 years – i llustrates the benefits.

### [Matra] Babcock-Hitachi wins €40m extension order f or Hungary's Matra power plant 05/19/2005

19 May 2005 - Babcock-Hitachi Europe (BHE) has rece ived the order to extend the Matra lignite-fired power plant from Matra Kraftwerk AG, with head offi ces in Visonta, Hungary. The order is worth around €40m ($50.6m).

BHE will be supplying two turnkey gas turbine syste ms. 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 o f 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 c oncept and final planning, supply and erection of t he components, quality assurance management and system commissioning. For Klaus-Dieter Rennert, Chief Operating Officer of the BHE board of directors, "t he contract award reflects well on the competitiveness of the Hitachi gas turbines in the wake of operating condition optimization in Europea n power plants by experienced Oberhausen BHE speciali sts." 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 customer needs in Europ e is of enormous help," says the managing director, "in getting across the product benefits o f technology to the customer."

Apart from a greater capacity, the two upstream sys tems 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 powe r plants -plant that generate electricity for base load requirements. Consequently, the operator can react considerably more flexibly to electricity market demands. And there is also something positive for t he environment: both systems will lower specific CO2 emissions of the two lignite-fired units by som e 10 per cent.

Matra targets new gas turbines

Hungary’s Matra Power Plant has signed a 40 million Euro contract with Babcock-Hitachi Europe GmbH to build gas turbine generators, Interfax reported, citing the plant telling MTI on February 18. The n ew generators, to be in operation by early 2007, will boost the plant’s capacity by 92 MW to 928 MW. Matra also signed a 20 million Euro contract with H itachi Europe GmbH to service the turbine until 202 1. Matra will finance the project from its own funds. Babcock-Hitachi Europe will build two gas turbines, of 29 MW capacity each, to two 212 MW existing blocks of the power station, which has a total of five blocks. Steam from the two generators will add an a dditional 34 MW capacity combined. The new generators will increase the efficiency of the two blocks where they will be built from 20 percent to 37Page 9 of 25

percent. The gas-steam cycle generators themselves operate at 46.5 percent efficiency. The new generators will also reduce the two blocks’ CO2 out put by 10 percent.

### [GE] GE Supplies New Turbines, Unveils New Retrofit Technologies that Increase Plant Capacity and Efficiency General Electric (NYSE: GE) is deploying gas turbin es at power plants in the U.S. and Saudi Arabia, an d 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 wi th the media at PennWell’s annual Power Generation
Week conference in Orlando.

In the U.S., GE will supply two of its highly effic ient and flexible 7F.05 gas turbines to Calpine Cor p. for the York 2 Energy Center, a nominal 760-MW, dual-fu el combined cycle plant near York, Pa. That project is adjacent to Calpine’s existing York Energy Cente r. The turbines are to be delivered to the site in
December 2015.

These turbines will use GE’s Dry Lower NOx 2.6+ dua l-fuel combustion system, which reduces NOx emissions to as low past 9 parts per million during gas-fired operations without using water injection technology. The turbines will also be able to opera te on low-sulfur diesel fuel.

In Saudi Arabia, the first four of GE’s 7F.05 gas t urbines at Saudi Electric Co.’s Power Plant 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 capacity by 2020. The eight units at PP12 ar e 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 - which can be built as part o f
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 McElhinney, GE’s president and CEO of Pow er Generation Services: “These solutions will provide our customers with the operational flexibil ity to quickly respond as their needs evolve over
time.”

The DLN 2.6+ solution adds fuel flexibility, allowi ng burns of up to 25 percent ethane or propane from shale gas, along with regular natural gas. The syst em 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.Page 10 of 25

The Advanced Compressor can increase efficiency (by up to 2 percent), output (by up to 12 percent) and operational availability. This system is new to the retrofit market, but already being used on new 7F. 05 gas turbines.

### [DTEK Vostokenergo] Emerson chosen to automate DTEK Vostokenergo thermal power plant in Ukraine PlantWebTM technologies chosen for project to increa se output, reduce fuel consumption at Lugansk
Unit 10

PITTSBURGH (May 31, 2011) – Emerson Process Managem ent has been chosen to provide new control, measurement, and automation technology for Unit 10 of the Lugansk coal-fired power plant in northeastern Ukraine. Emerson’s PlantWebTM digital plant architecture will play a key role in the Vostokenergo generating company’s project to modern ize the Lugansk thermal power plant.

“Reconstructing Unit10 will help us increase its ge nerating capacity from 175 to 210 MW while reducing fuel consumption,” said Alexander Nagorsky, operati ons director for Vostokenergo LLC. “Commissioning of the unit is scheduled for the beginning of this autumn, and within five years we expect to replace obsolete equipment in five more units with reliable , high-quality technology that will also help impro ve the plant’s technical and economic performance.”

As part of the PlantWeb architecture for Unit 10, E merson will provide its OvationTM expert control system, Fisher® control valves, and Rosemount® inst ruments for measuring flow, level and pressure of steam and water. Plant personnel will use Emerson’ s AMS Suite predictive maintenance software to detect and diagnose problems before they disrupt po wer-generating operations.

“With the combined capabilities of these integrated technologies, Vostokenergo can look forward to gaining the full benefits of the PlantWeb architect ure,” said Alexey Etkin of Emerson Process Management.

The project is the first in the Ukrainian power ind ustry to use Emerson’s AnnubarTM averaging pitot tub e technology rather than traditional diaphragm-based sensors to measure the flow of process water and steam. The Annubar sensors’ insertion technology h elps reduce installation and maintenance costs as well as ongoing energy costs.

Emerson also provided automation design, installati on, or commissioning services for the modernization project.

Lugansk is one of three plants operated by Vostoken ergo LLC, which is part of the vertically integrate d DTEK energy company. Emerson previously modernized the control systems of Units 5 and 7 at Vostokenergo’s Kurakhovskaya plant and control of U nit 2’s turbo feed pump at the Zuyevskaya thermal power plant.

### [Belchatów] Belchatów Power Plant, Poland
Key Data

Plant Type Coal-fired power plant

Location Bełchatów, łódź province, Poland

Start of Operation 1988Page 13 of 25

Output 4,440MW

Plant Owner PGE Elektrownia Belchatow

Boiler Supplier Rafako under license from Sulzer an d EVT

Turbine Supplier Zamech under a license from Brown B overi & Cie

The 4,440MW Belchatów power plant is located near B elchatów in the lódz province of Poland. Operated by PGE Elektrownia Belchatow (PGE), it is the biggest lignite-fired power plant in Europe. Th e plant was commissioned in 1988 and currently accoun ts for 20% of the Polish power market.

In January 2011, PGE commissioned the 13th unit wit h 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 expansion, 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 r ating of 1,150t/h, the boilers 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 s craper and belt feeders. Eight mazut burners are used to light the coal with air supplied by two air fans and exhaust fans. The combustion chamber of t he boiler features two circulating pumps.

Superheated steam generated by the boiler is sent t o single shaft turbines. The turbines feature four
control valves and are rated at 370MW with a turnov er of 3,000rpm. A programme to modernise the turbines was carried out between 1997 and 2004, whi ch increased the capacity by 10MW and reduced heat energy consumption by 210KJ/kWh.

A synchronous generator with a bipolar structure an d cylindrical rotor generates electricity.

Development

In April 2009, PGE launched a retrofit programme fo r unit 6 of the power plant to increase the unit's output to 390MW-400MW.Page 14 of 25

The upgrade programme will retrofit the turbines an d auxiliaries, electro-hydraulic control system and instrumentation and control (I&C) equipment. The bo iler firing system will be upgraded to reduce emissions to 200mg/Nm3 for CO and NOx. A new distri buted control system, eight new pulverised coal burners and 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 ea ch. High pressure and intermediate pressure turbines an d auxiliaries, bypass systems and I&C equipment will be installed as part of the retrofit. New elec trostatic precipitators will also be installed to r educe 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 ret rofit the unit 6."

IFS implemented an ERP system at the plant, which h elped in quick access to operational data and enhanced document management.

Emerson was contracted in November 2009 to carry ou t the modernisation of units 5 and 6. The company had earlier won a contract to automate unit s 3 and 4. Under the 2009 contract, Emerson installed its PlantWeb digital plant architecture a nd Ovation expert control system to upgrade the uni ts'
I&C.

Emerson will also install 110 Rosemount wireless te mperature 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 wort h $95m to automate units 7 to 12.

The units 7 and 8 of the plant are planned to be sh ut down in January 2012 and June 2012 respectively
for modernisation. These units will be recommission ed in 2013.

Contractors

Rafako constructed the boilers for the plant with t echnology licensed from Sulzer and EVT.

The turbines were manufactured by Zamech under a lic ense from Brown Boveri & Cie (now part of ABB). The generators were manufactured by Dolmel (now par t of Alstom Power). Hayward Tyler supplied the circulating pumps.

In 2008, Hempel provided its high quality protectiv e coatings for the cool water pipelines of the plan t. Babcock Borsig Service was awarded a contract in 20 09 to supply flue gas displacement system for units
5 and 6.

SGS served as the technical consultant for the 13th unit of the plant. PERI supplied a falsework combination consisting of ST 100 stacking towers an d MULTIPROP aluminium slab props for the 13th
unit. ME Construct was also involved in the constru ction of the unit.Page 15 of 25

Alstom was awarded a €160m contract in 2009 to retr ofit the unit 6. In October 2010, Alstom was
awarded another retrofit contract worth €140m for u nits 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 un it 12. The pilot CCP will use Alstom's Advanced Ami ne Process with amine solvent supplied by Dow Chemical . It will capture about 100,000t/y of CO2.

In the second phase, a bigger plant will be built t o capture carbon emissions from the new 858MW unit. The new plant will capture 1.8mt/y of CO2 and is ex pected to be operational by 2015. The project will require an investment of $776m and has received a € 180m grant from the European Investment Bank in May 2010.

### [Bonanza] Deseret Power Electric Cooperative, Bonanz a 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 modificat ion and did not trigger PSD review. The 1998 Approval Order and supporting documentation state t hat boiler heat input was increased from 4381 MMBtu/hr to 4578 MMBtu/hr, and that approximately 2 0 MW from the upgrade will result from an increase in steam flow produced by the boiler. To d ate, the boiler has not been operated at its peak potential due to limitations of steam flow at the e xisting Turbine Generator. The Project will allow t he Turbine Generator to accept all of the steam flow t he Boiler is capable of producing. While the Ruggedized Rotor by itself will not result in any c hange to Bonanza 1’s emissions, the increased capac ity of the Turbine Generator to handle the Boiler’s pea k capacity will increase the Bonanza plant’s overal l potential to emit (PTE).

To our knowledge, we were never advised of, nor inv olved in, that action. We do not understand how this 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 emis sions by some physical change or change in its method of operation. We are concerned that the redu ctions in allowable lb/mmbtu emission rates mentioned in the “Permitting History” do not reflec t a reduction in actual emissions and what we are seeing are merely “paper” reductions.

### [Hawthorne] Completing a 550MW Pulverized Coal Fire d Utility Project 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 & Light (KCPL) with a difficult d ecision—replace the coal-fired boiler, or convert t o gas-fired combined cycle. Although most of KCPL’s p ower generating plants burn coal, Unit #5 was the only coal-fired unit at Hawthorn Station. Ultimatel y, KCPL decided to replace the destroyed steam generator with another coal-fired unit, and repower the existing turbine/generator equipment. By August, 1999 the utility, Burns & McDonnell and Bab cock & Wilcox had a plan in place to build a new, 550MW pulverized coal-fired facility and have it pr oducing power and revenue by June 2001.

### [Dunamenti] Alstom successfully completes the retro fit of the steam turbine island at the repowered gas-fired Dunamenti Power P lant in Hungary Alstom’s Thermal Services unit in Hungary has succe ssfully completed modernisation of unit 8 of the Dunamenti gas-fired power plant owned by Gaz de Fra nce Suez. The modernisation project awarded to 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 installat ion of a gas turbine from another vendor. The project s tarted in April 2009 and has been successfullyPage 17 of 25

completed with the commissioning of the retrofitted unit 8 in July this year. It has contributed to th e 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 emission s 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 feed water heaters were originally supplied by Alstom companies. Within the scope of this project, Alstom replaced the high-pressure steam turbine 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 Deák, Country President of Alstom Hungary sa id, “Alstom is proud to have been a part of the rehabilitation of Hungary’s biggest power plant. Re powering is a special engineering application that requires significant engineering capabilities to sy nchronise 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 service s we can provide to upgrade the power generation flee t in Hungary.”

Dunamenti is located near Budapest and is one of th e country’s biggest power plants with 6 x 215 MW steam turbine units and two other combined cycle an d cogeneration units. The plant has a total capacit y of 1736 MW. The retrofit of unit 8 labelled ‘G3’ wa s part of a bigger rehabilitation programme undertaken by Gaz de France Suez to reduce the envi ronmental impacts of their plant.

### [Korai] Maharashtra all set to upgrade old power se ts Monday, 27 July 2015 - 6:50am IST | Place: Mumbai | Agency: dna | From the print edition

Move will help increase generation capacity at lowe r costs than setting up new projects

To boost electricity generation and increase the ef ficiencies of its thermal power units, the state po wer generation utility is planning to modernise its old sets. This will help add capacity at lower costs t han setting up new projects and generate more power fro m lesser quantity of coal.

A large number of the Maharashtra State Power Gener ation 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 c apacity of 210 MW each.

Of the MahaGenco's 7,980 MW installed coal-based ca pacity, almost half (3,570 MW) is in these antiquated units, which have lower generation effic iencies. The modernisation project, which will add capacity and expand efficiency in generation at a c ost lower than that of setting up a new unit, has b een launched at the Koradi power plant. It will later b e expanded to four more units, namely one set each at Nashik, Bhusawal, Chandrapur and Parli, based on th is experience.

"We have undertaken the renovation and modernisatio n 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 t o increase the operational efficiency. However, the f oundation and the boiler's body will remain as it i s. This will increase the installed capacity of this u nit to around 228 to 230 MW from the present 210 MW

. Since these units are old, they have a plant load f actor of only 50 to 52% and this renovation will br ing it up to 80 to 85%. This means we can generate more po wer with lesser coal," said a senior MahaGenco
official.

The Koradi project was launched last year and the a ctual work has begun this month. It is expected to be completed by March 2016. The state will get funds f rom the World Bank and infuse the remaining amount as equity for the project, the official stat ed.

The official added that this modernisation cost jus t 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.

"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 wil l be on line by March 2016, will enable us to shut down old units for renovation and modernisation," the of ficial said.

MahaGenco has 7,980MW of its 11,237MW installed con ventional energy capacity in coal, with the remaining comprising of gas (672MW) and hydro power (2,585MW). The average weighted average costPage 19 of 25

of power generated by the utility is about Rs3.28 p er unit, with that of thermal being around Rs3.70 p er unit.

### [Polaneic] Alstom signs modernization contract wort h approximately 65 million euros for the Polaneic Power Plant in Polan d 07/05/2012

Alstom, the global leader in steam turbine retrofit ting, today announced that it has signed a contract worth approximately €65 million with GDF Suez Energ ia Polska S.A., which owns and operates Poland’s Polaniec power plant for modernisation of six units (units 2-7) of the power plant. The contract also includes the option of retrofitting an additional u nit (unit 1) of the power plant.

Połaniec Power Station is a coal-fired power statio n near Połaniec in Świętokrzyskie Voivodeship, Poland. It consists of eight units each with a gene ration 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 engin eer, 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 operati on in May 2013 and the final one will be handed over f or commercial operation in December 2014.
Decision about the modernisation of unit 1 will be taken before 2014.

The modernisation will improve the units’ availabil ity and reliability and will extend the plant’s lif etime by an additional 25 years. On average each unit wil l 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 manufactu red at Alstom’s steam turbine factory in Elblag.

The contract represents a further consolidation of Alstom’s retrofit experience in Poland and follows orders worth approximately €15 million to upgrade t he Kozienice and Lodz coal-fired power plants, signed earlier in March this year.

Alstom is also currently retrofitting the existing steam turbine of Polaniec power plant unit 9* to optimally match its new biomass-converted boiler. I t is expected to enter commercial operation by the end of this year.

### [Little Barford Power Station] Little Barford is a combined cycle gas turbine powe r 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 ge nerating capacity of 680MW enough to meet the electricity demands of over half a million househol ds.

The power station has one generating module, consis ting of two gas turbines and one steam turbine. The Station also has an open cycle gas turbine prov iding black start capability 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 t hat the upgrade will extend the life of the plant t o around 2025, and included replacing the two gas tur bines 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, equi valent to an additional 30,000 homes that can now be powered by the plant.

Emissions of nitrogen oxides (NOx) have been reduce d 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 provi de 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 gri d distribution system, the black start turbine will allow the power station to start up without taking electr icity from the National Grid.

The main fuel used to generate electricity at Littl e Barford Power Station is natural gas, however the station also has the ability to use gas oil as a ba ck up fuel.
