If you believe all you read, it mightappear very well indeed. Europe is now said to be one of the best situated continents forusing renewable energy systems - such as sunlight, wind, rain, tides, geothermal heat andbiomass sources.In the UK, since 2000, we have established 70 wind farms, comprising more than 800 turbines intotal. As more become established costs have fallen, and the final cost of getting electricity fromthe wind has dropped considerably. The good news is that windfarms are growing every year at therate of 30%, with a worldwide installed capacity of 121,000 MW in 2008 and they have now becomewidely accepted in the US and Europe. In the latest media reports the experts have suggested thatthe potential of wind energy is five times our total current global energy production, or 40 timescurrent electricity demand.The truth is that potential does not equal viable potential. You'll often hear claims that windpower could generate much more electricity than we could possibly use. Unfortunately, theseclaims are generally based on silly assumptions, such as all land with wind potential could beconverted to wind farms. Yes, we could theoretically knock down Central London and build windfarms over the land, but not even the Greens feel this is a viable option.Sadly, apart from onshore wind, which is just about cost-competitive with conventional electricityproduction, renewables are an expensive way of generating electricity. Unless there are specialcircumstances - supply security considerations, environmental subsidies, or remote locations awayfrom the grid - meaning that any electricity supply from a central source would involve extension ofa grid network - renewables aren't really economically viable.One can argue that conventional fuels don't pay an economic rate for the clean-up of theenvironmental mess they make, and that on a level-playing field, renewables make more economicsense. But the fact is, nuclear energy aside, fossil fuels don't yet pay the full cost of clean-up,although there are attempts to move towards this with carbon trading.Put simply, the question people have to answer is this:"Do you want it cheap - or do you want it clean?"July has proved a fertile month for organisations promoting renewable energy issues. There is nowa body with worldwide reach called the International Renewable Energy Agency (IRENA) - made upof experts from 129 nations - which has agreed to establish a headquarters in Abu Dhabi from whereit will advise on renewable energy. Media reports have suggested that Australia and Japan addedtheir names to the document establishing IRENA just hours before its inaugural conference in Sharmal-Sheik on June 29th - so, clearly, this is viewed as an important development.IRENA’s aim is to offer advice to world governments on technical and financial issues linked torenewable energy and promote and encourage the introduction of this kind of technology acrossdeveloping countries.EUROPE ASIA-PACIFIC MIDDLE EASTAFRICAAMERICASW ORLDWIDE I NDEPENDENT P OWER • JULY 20095

SHAREWATCHThe renewable energy questionJohn Sauven, Greenpeace's executive director, looks at the UK Government’s policytowards renewables whileWIP’s Christopher Hopkins reports on shares prices.July has proved an interesting monthfrom an energy point of view. The UKGovernment published two WhitePapers entitled: ‘The UK Low CarbonTransition Plan’ and ‘The UK RenewableEnergy Strategy 2009’. In these theGovernment has set out a number ofmilestones which it believes will beachieved by 2020. It projects that 1.2million+ people will be in green jobs andthat approximately 40% of electricity willbe from low carbon sources such asrenewables and nuclear. The Governmentalso includes coal with carbon-capturetechnology in this category. Clean coalemits less NOx and SOx but the only wayto avoid carbon emissions is to use carboncapture technology when burning it.In theory, theGovernment has pledgedthat the UK will be retiring 45% of itsenergy generating capacity by 2020 –more than any other European nation.The Transition Plan sets out how the UKwill attempt to meet the cut in emissionsin the budget of 34% on 1990 levels by2020. This is the reduction laid out in theClimate Change Act 2008 (which wasadopted into the UK statute books inNovember 2008). The Transition Planstates that a 21% reduction has alreadybeen delivered, equivalent to cuttingemissions entirely from four cities the sizeof London.John Sauven, Greenpeace's executivedirector, commented: "The Governmentmust prioritise renewable energy andenergy efficiency over everything else inthe sector. If they do this, Britain couldlead the fight against climate change,whilst providing hundreds of thousands ofjobs.

ALTERNATORSAlternators - what to look forEssentially, you want the greatest performance from an alternator for the least cost andwithout creating difficulties, explains Steve Wells of Mecc Alte UK Ltd.Selecting an alternator for a givenapplication is something often overlooked,writes Steve Wells.Even some very well-known hirecompanies will generally oversize agenerator to ensure that there are noproblems encountered at site. Probablythis is quite right as there are major costsinvolved in shipping generators around thecountry.For fixed generator applications theload, present and future is usually knownat the start, and such loads are becomingincreasingly more complex. It is still quitelikely that a specification for a generatingset will have 80% written around theengine and systems, but little left for thealternator. Alternators are important withregards to the load, to economy and toreliability and should command morethought.Different alternator manufacturers havediffering priorities, whether group-led orsimple design philosophies. Generallyspeaking, you want the most performancefrom the alternator for the least cost andwithout creating difficulties.The higher the efficiency, the less fuel isburned for a given power output. Here,there are differences betweenmanufacturers that are quite marked - upto 5% difference in efficiencies in somecomparisons.Although not directly proportional tofuel saving, it is in fact a fuel-saving usingthe higher efficiency machines. This is anod to the 'greens', and also for thoseseeking optimum power from the gensetto give them an edge in a tender, or touse the slightly lower power engineoption.Again, for optimum sizing and winning oftenders, the transient ability of thealternator could result in a smallermachine. Some projects will need to sizethe gen-set based upon the transient andnot the continuous load. In these casesLV alternator from Mecc Alte UK Ltd.the steady state condition means it is avery lightly loaded genset with all theconsequential problems encountered withengines and then ultimately its reliability.The alternator does not give a jot aboutlight loads, although if it has an goodoverload ability - 'current forcing' thenyou can have a smaller machine to thesame job. Systems exist now with theMecc Alte 'MAUX', the CGT's 'PMG/EBS' andthe Leroy Somer's 'AREP/PMG', but not allof theses are standard fixtures so bewareof the cost penalties.Some loads will create currentharmonics and affect the waveformproduced from the alternator and alsoadd to the heating effects in thealternator windings. Some loads arevariable peed motor drives, UPS systemsand furnaces. Here it is important tounderstand the level of harmonicsproduced by the load and the amount ofvoltage distortion the load will allow.Factors to consider when sizing themachine will include:- The AVR should have a dedicatedpower supply which is either separate tothe main power windings or derived froma differing vector. These will include theMecc Alte 'MAUX', the CGT's 'PMG/EBS' andthe Leroy Somer's 'AREP/PMG'.- Ideally, the regulator shouldsense on all three phases to get an overallpicture of what is happening to themachine - because it will still be sensingthe distorted output waveform from thestator.- Oversize for either heatingand/or to reduce output voltagedistortions.- The oversizing has the effect ofreducing the sub-transient reactance (x"d)of the machine. The lower the value thebetter the machine will cope with thedistorted loads. Some manufacturers havemachines with a low x"d across most ofthe range which means less oversizing -smaller machine, more compact, less cost- win tenders.Not all manufacturers have the samephilosophy - to provide all of this in acompact, reliable and proven package ata competitive price. So look around atwhat is on offer from the most popularmanufacturers. Do not follow like sheepto the 'perceived' best - because they maynot be the best at all.WIPInternet linkwww.meccalte.co.uk14JULY 2009 • WORLDWIDE I NDEPENDENT P OWER

CHP SYSTEMSOptimising municipalCHP systems for usersDrawing on CHP modelling, Asko Vuorinen, General Manager, managing Director ofModigen Ltd, explains how municipal CHP systems can be optimised in terms ofprofit and efficiency.Municipal power systems aredesigned to provide an area of acity with electricity and heat. Asan example, let's take Finland - the mostnorthern of the EU countries. Thepossibilities for CHP generation here aregreater than for almost anywhere else inEurope because of the heating needs ofits cities.Let's consider the electrical loadduration curve of a model city in Finlandwith, say, 100,000 inhabitants. The peakelectricity load would be 250 MW, or 2.5kW/capita. The electricity consumption is1,200 GWh, or 12 MWh/capita. The fullpower hours in the system are 4,800 h/a(1200 GWh/250 MW).The peak load of heat consumption is400 MW, or 4 kW/capita. Annual heatconsumption is 1,200 GWh, and is thesame as electricity consumption. Thus,the annual full power hours in the heatsystem are 3,000 h/a (=1200 GWh/400MW). Heat is distributed via a districtheating network which has an inlettemperature of 90°C and a returntemperature of 50°C.In the case being considered all of theelectricity will be purchased from thenational system, and all of the heat willbe produced with hot water boilers.Alternative municipal power plantsinclude a gas engine (GE) plant, adualfuel combined cycle (DFCC) plant,and a coal-fired CHP plant.The typical gas engine plant (GE-32/32)has four 8 MW engines. It can produce 32MW of electricity and 32 MW of heat forthe district heating network.The dual-fuel combined cycle plant, onthe other hand, (DFCC-67/61) has four 16MW dual-fuel engines and one 3 MW backEngine room of a major CHP project in Hungary [pic. courtesy of Wartsila]pressure steam turbine. It can produce 67MW of electricity and 61 MW of heat. Wecan evaluate the heat balances ofalternative power plants using anevaluation program. In the first place, wecan study each alternative, one-by-one,and try to find the alternative offeringthe best profitability as measured insimple payback time of the marginalinvestment costs.Investment costs riseIn decentralised or centralised powerplants we can assume that the investmentcosts for power plants are rising at anexponent of 0.9, in line with theincreasing size of the power plant. Thus,large plants mean, on average, lowerinvestment costs per invested kilowatt ofpower.However, the costs of energy distributionsystems rise with the size of powerplants. Therefore, there is always anoptimum size for the system, where thegeneration and distribution costs are at aminimum level. Investments needed inthe electricity and heat distribution networksshould total less than the savingsrealised from the construction costs of alarge plant. However, this largely dependson the type and size of the area served bythe power plants.If the area served is large, and there areseveral local consumption centres, itcould be more economical to build localplants in each centre.There are also security aspects involved.If the plants are all on one site, a singlefailure of the system caused by, say, afallen tree or corrosion in the districtheating pipes, could result in the entirecity being blacked out. Such failures canbe limited by having at least two sites, sothat should a network failure occur, only50% of the system will be affected.In general, a modern power and heatsystem should be planned to manage asingle failure criterion, whereby singlefailures cannot black out the whole city.There should, therefore, be reserve power16JULY 2009 • WORLDWIDE I NDEPENDENT P OWER

CHP SYSTEMSGyor in Hungary: 55% of the peak demand for heat is covered by the CHP plant.plants and heat boilers included in thesystem.If a single unit power plant produces100% of the heat load of a city, it wouldneed a 100% backup boiler. If a powerplant has been constructed using sevenunits, then the backup boiler requirementwould be only 15% of the total capacity.The costs of the additional reserve boilercapacity should be included when makingthe cost evaluation.In Finland, 2.4 million inhabitants live inhouses heated by district heating systems.This corresponds to 46% of the totalpopulation of 5.2 million.In the 30 largest cities the totalelectrical output of CHP plants in thosecities is about 3,500 MW, and the averagecapacity calculated per district heatingcustomer in those cities is 1.7 kW/capita.Very few cities have less than anestimated 1 kW/capita. The cities ofEspoo, Jyväskylä and Hämeenlinna havethe largest potential for new CHPcapacity. Espoo could triple its capacityand build plants generating 250 MW.Jyväskylä and Hämeenlinna couldincrease their capacities by 50% - 100%.Jyväskylä could build a 50 - 100 MW plantand Hämeenlinna a 30 - 60 MW plant.Combined heat and power plants offerthe lowest cost in the power system andthere should be more of them.In the north, where the heating season islong, CHP plants can generate 100% of thecities' electricity needs. The largest citiescan, with the right planning, beindependent of outside electricity.Instead, they can have gas engine andcombined cycle plants, which have apower-to-heat ratio of one or more.A city can then build CHP capacity of 2.4kW/capita. Smaller cities can be almostindependent of outside power, if a majorityof the people are living in houses heatedby district heating. With gas engineplants, capacity can reach 2.0 kW/capita.The CHP plants are profitable investments.The costs of power generation arelower because of the high total efficiency,which is 80 - 90%. Maximisation of theCHP capacity can be achieved by buildingCHP plants which have the highest heatto-powerratios or alpha values.Local power plants can also be built tobe independent of the national grid.Thus, if the grid has a disturbance, thelocal power system can be separated fromthe grid. Under this scenario, the localsystem should be built using smallerpower plants that can meet the singlefailure criterion.This scenario was experienced inNovember 2006 during the blackout of theWestern UCTE-system. Several cities werethen without power, but Barajas Airport inMadrid had no interruption, because thesix Wärtsilä 6 MW dual-fuel engines wereautomatically switched for island modeoperation. This type of multi-unit powerplant is also capable of generating enoughpower should one unit be out of operation,or if gas pipelines are broken.Asko Vuorinen's book "Planning OptimalPower Systems" is available for internetorders atwww.optimalpowersystems.com.Internet linkwww.wartsila.comwww.wartsila.com/usaWIPSolar Taurus T60MOBILE GEN SETS5.2 MW• Solar Maintained• 7 Units (Gen 1) & (Gen 2)• All Natural Gas• Mobile PCR U.G.

CONTROLS & MONITORINGGen-set controls & network outagesGen-sets and their controls play an important role in network maintenance and in thecontinuity of supply for end users, explains Roger Watterson, MD for DEIF UK Ltd.It is vital that outages are planned asmuch as possible and the supplymaintained. Many would say this shouldhappen at any cost - but, of course,safety remains a paramount concern,reports Roger Watterson.In the real world network operators havea gen-set supplier who can usuallyprovide correctly-trained and authorisedpersons to ‘back synch’ to the grid withsophisticated equipment in the safestpossible way.The ‘DEIF way’, for example, involvesusing a Remote Maintenance Box (RMB)which can be connected to a gen-set andthen the RMB can be moved up to 300metres away.This allows the operator to work somedistance from the gen-set, but still have avisual and audible indication of thestatus of the gen-set and its readiness tooperate in synchronisation.Coupled with a display indication of allgen-set readings, this makes for the safestpossible situation.Removing the fuse must be done at thecorrect time to avoid the obvious dangersof arcing due to operation whilst ‘out ofsynch’.The control unit is extremely fast, andstable synchronisation ensures maximumsafety when removing the fuse.The RMB can be positioned within easyreach of the operator, enabling him/herto stop the gen-set, synchronise the genset,deload the mains and go into island.The RMBfrom DEIF.At this point he can remove the RMB if itis required elsewhere, leaving the gen-setnow happily being supplied as the mainsfrom the customers’ point of view.This means that not only can one RMBbe used for a number jobs, but gen-setfitted with a standard AGC controller canbe also be used for any ‘normal’application at any time, thus allowing formaximum utilisation.This is the ultimate goal in the currentclimate for any operation manager, assetowner or business person.Safety remains a key factor and,therefore, operators have to be equippedwith the correct personal protectionequipment to suit this application alongwith the correct testing equipment.This includes specialist gloves andfaceguard along with the usual obviouspersonal protective equipment.The operators also have to be ‘approved’Inside the RMB.to be able to complete this necessarywork and would generally have networkengineers also in attendance. However,the RMB is designed to be very simple tocontrol.The step-by-step sequencer offers anintuitive user interface which makes theoperation extremely simple and servicevery easy. This leaves the operator toconcentrate on the many other technicalissues he has to consider.When the distribution network operatoris ready for the mains to be restored, theoperator simply plugs in the RMB andpicks up where he left off. Then, theSafety is of paramount importanceduring maintenance operations.operator moves to the next position onthe switch ‘synchronise to mains’ and theset will automatically synch to the mainswith the operator moving through thenext steps of ‘Deload Mains’ and ‘Stop’.This will complete the operation.The RMB can be unplugged duringoperations, stored away or used on thenext site awaiting planned outage.Once the operation has been completed,the gen-set can be moved to its next job,for instance, a rental situation such asAutomatic Mains Failure, peak lopping,load sharing with other gen-sets, etc. Thisensures the rental operator is maximisinghis costly assets.As the networks also have a wide rangeof older and existing installations to workwith, the RMB is designed to be flexible tofit in with this.It can cater for single or three-phasesupplies with very simple menu changes.Internet linkwww.deif.comWIP18JULY 2009 • WORLDWIDE I NDEPENDENT P OWER

GAS TURBINESGas turbines in Malmö, SwedenAugust 2009 is a milestone month for Sweden's Öresundsverket Project, Malmö's newgas turbine-driven power plant developed by Hitachi Power Europe. The new plant isone of the most advanced in Europe, reports Olaf Lipinski.It's big, it's Swedish and it representsthe ultimate in 21st Century powerstations and - best of all - it startsproducing power next month. Malmö'sÖresundsverket Project represents a totalinvestment over €300, includinginfrastructure for the connection ofelectricity, gas and district heating.Olaf Lipinski, Technical Project Head forthe Öresundsverket Project told WIP: "Thiscombined-cycle gas and steam powerplant, located in the southern Swedishport of Malmö, is one of the most modernof its kind. Its capacity amounts to 440MW for power and 250 MW for heat andunder combined operations the energy ofthe fuel gas is used to 89 % efficiency."In 2006 HPE and GE Energy obtained theorder to build the plant, with HPE takingon responsibility for the balance of powerplant equipment, overall plant design,constructional planning, implementation,erection and startup management. GEEnergy's contribution to the project wasits powertrain and instrumentation andThis is one of the most hi-tech CHPplants in Europe, says HPE.Malmo's new 440 MWe / 250 MW plant goes operational next month.control technology. The construction ofthe combined cycle plant presented theplanners with real challenges.On the one hand the key components -gas turbine set, steam turbine set, heatrecovery boiler - had to be integrated intothe existing building of a 1950s coal-firedpower plant.On the other, there were a number ofproblems associated with the state of thebuilding noticed by the HPE staff. Whenwork first commenced in September 2006the engineers reported problems withwater ingress and insubstantialfoundations."The supports in the turbine shop, forinstance, had insufficient bearing capacityand had to be revamped at considerableexpense. Moreover, hundreds of tons ofadditional steel girders were needed toprop up floor elements," reveals Lipinski.Its proximity to the port and the highgroundwater level caused furtherdifficulties. Site engineers had to positionsheet pile walls and pump water out toenable the foundation and piling work toproceed.At peak periods around 70 Hitachi Poweroffice staff and a workforce numbering500, including construction managementpersonnel on the site, were involved withthe building of the combined-cycle powerplant. The original intention had been forthe plant to be operating commercially atthe beginning of 2009 but instead therewas an eight-month delay."The difficulties had an effect on theschedule - the completed plant willeventually be handed over to E.ONVärmekraft Sverige AB next month, inAugust," Björn Ahrendt, CommercialProject Head involved with the Malmöfacility, tells WIP.Once the combined cycle power plant isfully operational it will not only besupplying electricity and district heat forMalmö but will also be making a majorcontribution to climate protection. This isbecause the power plant is part of arolling programme to replace existingcoal-fired stations in Scandinavia.According to the authorities, thisprogramme is projected to reduce carbondioxideemissions by approximately onemillion tons a year.Facts at a glance:Project Öresundsverket - CHP Malmö* 440 MWe / 250 MW plant commencescommercial operations August 2009* Total investment over 300m€ includinginfrastructure for connection ofelectricity, gas and district heating* The project used some of the olderfacilities at Öresundsverket* Maintenance (LTSA) - main supplier;operation - E.ON Värme* Built and equipped by Hitachi PowerEurope and GE Energy.Internet linkwww.hitachi-eu-power.comWIP22W ORLDWIDE I NDEPENDENT P OWER • JULY 2009

BLADINGTurbine blade advancesIn power generation, aggressive targets have been set for reduced CO2 and nitrogenoxide emissions from gas turbines. This means using a new kind of abrasive tip materialtechnology for turbine blades, says Scott Wilson and Thomas Peters of Sulzer Innotec.Current abrasive tip technologyavailable in the market place isbased primarily on the use of cubicboron-nitride abrasive particles which arebonded to the blade tip in an oxidationand creep-resistant matrix alloy, usingproprietary alloy deposition technology,write Scott Wilson and Thomas Peters.Cubic boron-nitride is one of the hardestmaterials known, next to diamond, and isan excellent abrasive material. However,it has one drawback; it oxidises rapidlywhen exposed to temperatures above900°C and lasts less than 100 hours in theaverage turbine environment.Several alternative abrasives to cubicboron-nitride were investigated in the EUfundedABRATIP program (AdvancedAbradables and Tip coatings for gasturbines), with participation from SulzerInnotec, Sulzer Metco and severalaerospace OEMs. The only candidatewhich exhibited equivalent cuttingperformance against ceramic abradableswas silicon carbide, which has excellentResearch has suggested that a siliconcarbideabrasive solution could beprovided to OEMs for their bladetipping needs.The rotor of a huge gas turbine repaired by Sulzer Turbo Services after a severeoutage in a combined-cycle power plant. The repair was faster and cheaper than areplacement.high temperature oxidation resistance incomparison to cubic boron-nitride.However, it too has an inherent thermodynamicinstability when brought incontact with turbine blade nickel-basedalloys. It will react with these alloys athigh temperature and disintegrate.R&D activities have continued todevelop an effective silicon-carbideabrasive solution which could be providedto OEMs for their blade tipping needs.Ceramic barrier coatings were applied tosilicon-carbide particles, but with onlylimited success as these tended to crackarising from thermal and elastic mismatchstrains at sharp corners. Additional effortswere made to find a more compliantbarrier coating.Then came an idea to use a reactivemetal layer such as chromium toneutralise the reactivity of a siliconcarbide surface. A more thermodynamicstable chromium-silicon-carbide barrier isformed when chromium is brought intocontact with silicon carbide at elevatedtemperatures.A chromium barrier coating was thenapplied to silicon-carbide abrasiveparticles successfully, which were thenused in blade tipping trials.Sulzer Innotec embarked on feasibilitytrials to fix the chromised SiC ontostandard turbine blade alloys using adedicated laser-weld deposition process.Good results were obtained where theparticles were successfully embeddedwithout serious damage to either particleintegrity or the chromised layer near thelaser beam heat input.Incursion tests using tipped bladesagainst ceramic abradable coatings,provided good results, report the authors.The program has progressed far enough tobe slowly moving out of the developmentstage and advancing toward marketopportunities. A series of developmentactivities are now underway inpartnership with Sulzer business unitsand its customers, says the company.

POWER PLANT REVIEWAustria’s Walsum 10 celebratesA major international celebration took place at Austria’s Walsum coal power plantfollowing its first successful boiler pressure test. WIP has the story.Amilestone has been reached withthe successful conclusion of theboiler pressure test at Austria’snew Walsum10 coal power plant.It’s taken two and a half years to buildat a cost of EUR 820 million to thepurchasers - Evonik Industries AG, theindustrial concern from Essen, and EVNAG, energy supplier from Lower Austria.Despite the fact the plant won’t be fullyfunctionaluntil 2010, both companies,along with Hitachi Power Europe GmbH(HPE), celebrated with a formal ceremonyin Duisburg-Walsum this month.A power plant with a 45%+ efficiency,Walsum features a 106-metre high utilitysteam generator (boiler), the mostcomplex single component of the facility.Coal power plants in Germany generallyhave an average of 38% efficiency andacross the world is it is only 30% perplant, making Walsum a very special siteindeed.2010 will see extremely hot steam (over600°C) under a very high pressure(approximately 274 bar) being generatedin the utility steam generator. This steamwill then flow into a turbine with angenerator converting the moving energyinto electrical power. The boiler pressuretest now officially endorses the ability ofthe boiler to withstand the high pressures.Christa Thoben, Economics Minister for North-Rhine Westphalia, took part in aceremony this month to mark the successful boiler pressure test at Walsum 10.The new Walsum 10 - designed to reduce overall CO2 emissions in North-RhineWestphalia by 2020.Around 9,900 tons of steel have been usedin the project. The piping has a totallength of approximately 450 kms and35,000 welds had to be welded at thepressure part. Modern materials areresponsible for the high efficiency. They,in turn, allow higher temperatures andpressures to be created in the boiler, saysHitachi.More than 300 guests, including ChristaThoben, Economics Minister for North-Rhine Westphalia (NRW), participated inthe official ceremony. "There is no alternativeto highly efficient, ultra-moderncoal power plants such as Walsum" saidThoben."Highly efficient and resource-conservingplants such as Walsum 10 enable us touphold our responsibility in climateprotection matters", said Dr. Klaus Engel,Chairman of the Executive Board ofEvonik Industries AG.“Because of the higher degree ofefficiency Walsum needs less fuel for thesame output compared with today's powerplants.,” he concluded.WIPInternet linkwww.hitachi-power.com30JULY 2009 • WORLDWIDE I NDEPENDENT P OWER
