Globeleq, a power company owned by Actis, has begun construction on a 139MW expansion for its existing Azito gas-fired power plant near Abidjan, Côte d'Ivoire. Completion of the project is expected in early 2015, at which point the nominal capacity of the plant will be 420MW.
Improvements in energy efficiency and changes in the manufacturing output mix have resulted in a significant decrease in energy intensity in the US. Total energy consumption in the American manufacturing sector decreased by 17 percent in the period from 2002 to 2010, despite only a 3 percent decrease in gross output, according to recently released data from the US Energy Information Administration (EIA).
New Zealand's Nova Energy, a subsidiary of the Todd Corporation, has opened its new gas-fired co-generation 100MW McKee Power Plant in Taranki on the country's North Island. The power plant is designed as a peak time plant and has a start up time of 15 minutes enabling it to respond quickly to changes in electricity demand, but can also operate in baseload mode if necessary.
Germany has emerged as a leader in the European Cogeneration market due to the country's strong commitment to energy efficiency, comprehensive policy promotion through the combined heat and power (CHP) support scheme and the government's decision to phase-out nuclear power is revealed in the recently released COGEN Europe report European Cogeneration Review – Germany.
Natural gas is set to remain important in transitioning the UK to a low-carbon electricity producer in the short term future, but can only play a more significant role beyond the 2020s if carbon capture and storage technology (CCS) is deployed on a commercial scale, according to a report from the London School of Economic’s (LSE) Grantham Institute on Climate Change.
Gas consumption in India has grown at an annual rate of 10 percent from 2001 to 2011 despite insufficient pipeline infrastructure. Natural gas mainly serves as a substitute for coal in electricity generation and with 45 percent of total use, the power sector is currently the largest user of natural gas in India, according to a country specific energy analysis from the US Energy Information Administration (EIA).
Natural gas fired power plants will continue to face severe difficulties to stay in the merit order in competitive OECD Europe power markets in such as Spain, Germany and the UK, as dispatch of coal plants stays more economic at current fuel and carbon emission prices, Dennis Volk, gas and power market analyst at the International Energy Agency (IEA) told Gas to Power Journal in an interview.
"Under current market conditions, gas-fired plants have no longer a big role to play in much of OECD Europe ..."
The Cockenzie Power Station in East Lothian, Scotland has shut down all four of its turbines after using up all of its permitted running hours under EU regulation. Owner and operator ScottishPower already has planning permission, obtained in 2011, to build a new 1000MW gas-fired combined-cycle gas turbine (CCGT) power station on the site of the now shut down Cockenzie plant.
Wärtsilä has launched a new product called the GasReformer for turning gas associated with the production of oil into energy. Traditionally such gases would be flared and wasted but the GasReformer uses steam reforming technology to convert gases rich in hydrocarbons into a methane rich product which can be used as fuel in gas fuelled engines.
The use of natural gas to generate electricity in Japan was up by 15 percent in 2012 when compared to 2011, according to the US Energy Information Administration (EIA). Japan's use of all fossil-fuelled power generation was also up 21 percent in 2012 when compared to 2011, and now represents 90 percent of the country's energy mix.
Temporary energy provider Aggreko has signed Tri-Party Power Purchase Agreements (TPPA) with Mozambique utility Electricidade de Moçambique (EDM) and Namibian utility NamPower to provide them with up to 32MW and up to 90MW of gas fuelled power, respectively from its interm power plant at Gigawatt Park in Ressano Garcia, Mozambique.
As dispatch patterns shift, gas-fired power plants can now increasingly be described as intermittent energy sources, much in the same way as renewables, Richard Sarsﬁeld-Hall, principal consultant at Pöyry Energy Consulting, said at this year's FLAME Conference in Amsterdam. Weather conditions impact the output of wind and solar installations and subsequently determine what levels of backup power is required from combined-cycle gas and coal plants on an intermittent basis.
