Empowering Western Europe’s consumers
Although Western Europe has a liberalized electricity market, consumers in the region still tend to buy power from within their own borders.
CHP – the value of greater global investment
The International Energy Agency’s Thomas M. Kerr presents a summary of a new report from the CHP/DHCCollaborative, which was launched in March 2007.
Black gold: the murky economics of coal fired power generation
Coal fired generation, the bête noire of the environmental movement, is making a comeback against all the odds.
Doing it right: The four seasons of wind farm development
Even though wind power is now a maturing industry, for developers there are still pitfalls to be avoided if a project is to be successful.
How to prevent the credit crunch taking a nasty bite out of plant assets
The current financial turbulence is hitting the power generation industry. Tom Roche of US firm FM Global explains how the value of risk management and loss prevention has never been higher.
Capturing the moment: an underground revolution
Carbon capture units could be the next big thing. Relatively low cost, suitable for retrofitting and using commercially available components, Doosan Babcock’s Oxycoal units could become standard kit for coal fired power plants – as common as flue gas desulphurization units in fact.
Restoring power after China’s big chill
When a harsh winter caused the loss of electricity supply in several provinces in China earlier this year, a struggle ensued to repair transmission lines and pylons to get power back to those regions as quickly as possible.
Heavy-duty gas turbines’ fuel pick ‘n’ mix
Power generation plants have to be increasingly flexible in the range of fuel that they burn, which means that gas turbines have an important role to play here.
Masdar City: Arabian science-fiction dreams to become science fact
In just seven years from now, a barren piece of Abu Dhabi desert will become the most ecologically advanced, innovative and ultra-modern development in the world: Masdar City.
More juice from your engine
Anders Ahnger of Wärtsilä explains how – at a time of increasingly stringent environmental limits and rising fuel prices – combined-cycle techniques can increase the power output and efficiency of plants that use medium-speed gas and diesel engines
Carbon capture and storage developments Down Under
The move to decarbonize coal-based electricity generation has stimulated global efforts in the research and development of new low and near-zero emission technologies.
Lignite power generation comes clean
Bulgaria is replacing two nuclear plants with a 670 MW lignite fired power station in the country’s first IPP project.
A distributed utility model for Europe: Multiple on-site cogeneration plants
Europe’s utilities are under considerable pressure to change to more liberalized and sustainable models.
Fine-tuning FGD via nonlinear modelling
Nonlinear modelling has helped many industries optimize their processes, but awareness of this technique in the power generation sector is limited.
Turning the tide on marine power generation
The installation of the world’s first commercial-scale tidal current system in Strangford Lough, Northern Ireland, is a landmark development in the realization of the UK’s potential to generate clean electricity from the seas around its shores.
Breaking records: new standards set for XLPE subsea cables
A Norwegian application of cross-linked polythene insulated (XLPE) submarine cable has broken the record for the highest operating voltage used with this technology.
In sync: Connecting generating sets to the grid
Engineers often just assume they need standby generation, but if they want to generate revenue by selling power to the grid then it is worth investing a little more in a prime mover generator.
Q7 breathes new life into offshore wind financing
Dutch offshore wind farm Q7, which is expected to begin full operation later this month, has attracted a lot of attention, not least because of its unique and award-winning financing structure.
Keeping a laser eye on particulates
Degradation of gas turbine inlet filters leads to corrosion of compressor blades and, ultimately, their catastrophic breakdown.
Up and running in no time at all
Diesel engines’ high efficiency and short lead times make them suitable for projects to be constructed under power purchase agreements.
Coming in from the cold: Chile takes a belated step towards renewables
With the approval of the target of ten per cent of all electricity produced to come from renewable sources by 2025 by the Senate, Chile appears to be finally turning its back on its dependence on foreign gas, particularly from its neighbour, Argentina.
Transforming disaster into success
When RWE npower’s Aberthaw power station experienced the unexpected failure of two of its generator transformers during its peak revenue period it needed to find and install replacement units as quickly as possible.
Raising plant profitability by cutting maintenance costs
An increasingly competitive energy market means that the management of power stations has to be ever more effective at maintaining profitability.
Producing power from landfill in South Africa is a gas
A local government authority in South Africa is developing a waste-to-energy project in South Africa under the Clean Development Mechanism of the Kyoto Protocol.
Gas turbines and green bananas: 60 per cent efficiency
Siemens’ latest gas turbine is set to offer efficiency in combined-cycle operation of more than 60 per cent.
Keeping pulverizing equipment online
Drive trains for pulverizing equipment in a coal-fired plant can fail and result in expensive downtime of the whole power station.
Italy needs to face up to the future
Italy is increasingly reliant on ever-more expensive natural gas imports for its power production, but there are alternatives.
Italy’s love affair with large combined-cycle set to continue
In an exclusive interview with PEi, Carlo Luzzatto, service and marketing business development director of Ansaldo Energia, discusses his home country’s continued dependence on gas fired power generation despite rising prices, and explains why Ansaldo Energia is able to successfully serve this important market.
