The world's largest concentrating solar plant – the 280 MW Solana Generating Station, located in southwest of Arizona, US – is being built beside a substantial fossil backup plant – the 2,334 MW gas-fired combined-cycle Gila River Power Station.
At the 2013 Russian International Energy Forum in St. Petersburg, Siemens Gas Turbine Technologies (SGTT) and power producer OGK-2, an open joint stock company, sealed a long-term service contract for PGU-800 – Russia's largest combined cycle power plant (CCPP).
Long-term regulatory stability is key for helping make new cogeneration developments more attractive for European industry, Dave Brownell, Refinery Manager at ExxonMobil told Gas to Power Journal at this year's COGEN Europe annual conference in Brussels. "In Europe, we're looking for stability in the rules of the game; stability in terms of regulations. A large cogen plant is an investment of hundreds of millions of euros, typically takes four to six years of project development and the operational life of the unit exceeds 30 years," he said.
GDF Suez' fourth gas-fired plant in France - the Dunkirk natural gas-fired combined cycle power plant (DK6) - "is planned to remain in full operation", GDF Suez confirmed. Fuel economics of the 788 MW CCPP plant are more advantageous, it said, as the plant is operated by burning blast furnace gas and the coke oven gas from a nearby steel mill.
At two US-based gas-fired combined cycle plants, controllability at the plants was a major issue, the responsible plant manager told Gas to Power Journal on condition of anonymity. Large natural gas swings caused large boiler pressure swings, which "created a situation where the load was swinging around a lot more than it needed to be".
Xcel Energy has proposed adding up to three new gas-fired peaking units to boost electricity production during periods of high demand in Minnesota and North Dakota. The proposal aims to replace coal-fired capacity at its Black Dog plant in Burnsville, Minnesota, which is due to be retired in 2015 by installing a 215MW gas turbine. It also aims at installing one or two, as needed, 215MW gas turbines at a yet to be selected site near Hankinson, North Dakota.
Spain saves an estimated €1,250 million per year thanks to the utilisation of combined heat and power (CHP) plants, representing an increase in savings of €70 million or 6 percent from two years ago. The figure is based on the sum of savings from primary energy costs included avoided grid losses, savings from avoided CO2 emissions, and energy transport and distribution savings.
The EU's 2004 CHP Directive has played an important part in the encouragement and recent introduction of CHP incentives across several member states, according to an International Energy Agency (IEA) report on Cogeneration and District Energy. The Directive establishes general principles for CHP policy but leaves detailed implementation to member states.
The introduction of Capacity Payment Mechanisms (CPMs) as suggested under the UK Electricity Market Reform may solve immediate problems of renewable output increasing revenue volatility for operators of coal- and gas-fired power plants, but could introduce many more, says James Marshall, Senior Consultant, Pöyry Management Consulting. "Conventional generation must expect to rely on a smaller number of hours to cover fixed and capital costs, with the timing largely determined by weather patterns with only short-term predictability," he told Gas to Power Journal.
GE has launched a new corrosion protection technology for refinery steam systems, based on its Steamate low salt amine (LSA) product series that have been specifically designed for refinery boiler and steam condensate systems.
EU carbon emission permits almost halved in value today in a record drop after the European Parliament rejected the backloading proposal that had been intended to temporarily curb the surplus of allowances. MEPs turned down the proposal by 334-315 votes, with 63 abstentions.
Hours before today's vote in the European Parliament on backloading, Société Générale analyst said they expect MEPs to adopt the proposal, in a move likely to propel up traded carbon prices in the EU ETS from current lows around 4.8€/t to closer to €6/t.
On the eve before the European Parliament's vote on backloading – a measure deemed crucial for the future of EU emissions trading - over 40 power producers and technology developers including Areva, Alstom, EDF, EnBW, E.on, GDF Suez, GE, Shell and Statkraft, have made a strong case in favour of the proposal, arguing current carbon price levels at 4-6 €/ton are "insufficient to stimulate investments in low-carbon power generation.
Clarke Energy, a distributor and service partner for GE's Gas Engine Business, has been contracted by the Nigerian medical equipment maker IMIL to build a 14MW captive combined heat and power (CHP) plant power the company's manufacturing of syringes and healthcare products for the West African Market.
Even though Malta's Delimara power station could be immediately converted from using heavy fuel oil to diesel and eventually natural gas, the government has decided to shelf such plans for about two years until the necessary gas transportation infrastructure is in place.
