GE, JP Morgan invest $225 million in NextEra Energy wind farm
February 28 2012 -
Expanding its renewable energy portfolio in Texas, GE Energy Financial Services has joined JP Morgan to jointly invest $225 million in a partnership that owns the 662.5-megawatt Capricorn Ridge wind farm in West Texas. The Capricorn Ridge wind farm has been in operation since 2007 and employs 342 of GE Energy’s 1.5-megawatt machines, and 65 of Siemens’ 2.3-megawatt machines.
GE Oil & Gas wins $1 billion Ichthys LNG project in Australia
February 28 2012 -
GE Oil & Gas has received contracts totaling more than $1 billion to supply equipment and services for the Ichthys liquefied natural gas (LNG) project in Australia recently. GE will provide rotating equipment, including gas turbines and compressors, for a new Ichthys LNG plant at Blaydin Point, near Darwin in Australia’s Northern Territory, and associated floating production storage and offloading and a central processing facility (CPF) located in the Browse Basin offshore Western Australia.
In the previous partof this series, the author set a new benchmark for combined cycle energy efficiency at 65 %. Direct use of natural gas, and a national energy policy with new regulations, coupled with efforts to save crude oil with the help of shale gas and the efficient combined cycle is the need of the hour.
Siemens Energy has received an order for a steam turbine generator to be used in a waste-to-energy plant equipped with combined power and heat generation in Plymouth, England. Once commissioned in 2014, the power plant - with an electrical capacity of up to 25 megawatts (MW) - is designed to cover the heat demand of Plymouth's Naval Base, cost-effectively and with low CO2 emissions.
IHI's palm-sized gas turbine generator offers 400W output
February 24 2012 -
Japan’s IHI Corp. has recently developed the world’s smallest and lightest gas turbine generator and plans to bring it to the market by 2015. The generator weighing 1.2 kg with dimensions of 8 cm in diameter and 12 cm in length can offer a maximum output of 400 watts using propane gas, kerosene or light oil for the fuel, and can run continuously for three hours.
After giving an account of full steam injection in early gas turbines in the previous article, the author discusses the various energy sources we have today, and says we need a comprehensive energy plan for further action.
Energy storage technology holds the promise to provide many benefits across the energy delivery value chain — from generation to transmission and distribution (T&D) to end-users. This technology is considered a key component for integration of high levels of renewable energy penetration and as an essential tool for smart, future electricity grids. It has additional benefits, such as, reducing emissions, serving as an alternative to a traditional generation plant, or acting as a tool for demand response, can be captured with the deployment of storage technologies.
Siemens has recently acquired Marine Current Turbines Ltd., the UK company based in Bristol, which develops and builds tidal power systems. The worldwide potential for power generated by tidal power plants is estimated at 800 terawatt-hours (TWh) annually. That is approximately 25 percent more than the total power demand of Germany and is equivalent to 3-4 percent of global power consumption. Coastal regions with strong tidal currents like those in the UK, Canada, France and East Asia offer major potential for the utilization of this technology.
In the previous part of this series, the first application of steam cooling and its combined cycle efficiency were discussed. In this article, the author writes about some of the early steam injected gas turbines, their overall cycle efficiency and their applications.
NEM has secured the order from Arabian Bemco Contracting Co. Ltd. in Jeddah, Saudi Arabia for 40 unfired dual pressure Heat Recovery Steam Generators (HRSGs) for the PP10 Combined Cycle Power Plant project. These steam generators with integral deaerator are of the vertical gas flow natural circulation type.
