Improvements to computer models and design methods for gas turbine inlet ducts have the potential to improve efficiency by as much as 5%, according to research from the Amirkabir University of Technology and Isfahan University of Technology in Iran. "The efficiency of diffusers of gas turbines could be improved up to 5% by using this method. This improvement could then increase the efficiency of gas turbine cycle up to 0.5%," Ali Madadi, a member of this research team on the project told Gas to Power Journal.

Engine maker Wartsila, the EPC turnkey solutions provider for power plants, has pioneered what it calls the 'Dry Flexicycle' concept that drastically cuts down water usage for generating electricity. "There is really, really no water consumption for the power plant itself for the operation," Risto Paldanius, Director, Business Development at Wartsila told Gas to Power Journal in Kuala Lumpur.

With a few more months to wait until a new EU Commission and a new Ukrainian parliament are in place, Société Générale is anticipating a short interruption in gas transits through Ukraine this winter and recommends buying Q1 15.

A new project in Rwanda promises to capture methane that has been dissolved in a lake and use it generate power, according to project developer Symbion Power. “This is the largest concession that has been issued so far and first power may be expected from the plant 15 months from execution of the Power Purchase Agreement,” Paul Hinks, chief executive of Symbion Power told Gas to Power Journal.

Keen to achieve higher gas penetration, China's State Council is targeting to reach a gas supply capacity of 400 to 420 Bcm by 2020. Last year's pricing reform has improved the economics of pipeline and LNG imports as it effectively links the city-gate price to oil-indexed contracts and is "likely to lead to increased supplies", while strict environmental policies will enforce more gas use for power generation, writes Michael Chen, OIES visiting research fellow.

As the European Commission has set targets for energy efficiency in the EU's climate and energy policy framework, COGEN Europe now calls for a greater commitment to expanding combined heat and power generation capacity.

"China is incredibly smart on the gas front," Giuseppe (Joseph) Jacobelli, Bloomberg Intelligence told Power-Gen Asia in Kuala Lumpur. They have been  aggressively exploring gas domestically besides building some  international gas pipelines into the country from Myanmar, he noted, adding that they have been building a lot of LNG terminals.

UK power producer Carlton Power has signed an agreement to construct a 1.8 GW gas-fired power station in Trafford, England. The firm has also agreed to take over GE’s stake ina separate 1.5 GW plant in Thorpe Marsh.

The Philippines will soon have to evolve a policy for LNG contracts as the existing concessions for gas from Malapaya runs out in 2024, Sarah Fairhurst, of the Lantau Group, Hong Kong, has told Power-Gen Asia 2014 in Kuala Lumpur. 

Indonesian state-owned power producer Perusahaan Listrik Negara (PLN) started operation at its 1 GW Tambak Lorok plant in central Java this week after pipeline infrastructure was completed to secure a switch to natural gas. The plant previously ran on diesel oil but has been idle since 2011.

Gas will continue to have a significant share in Malaysian power generation, vice-president of the country's biggest utility, Tenaga Nasional Berhad (TNB), told the Power-Gen Asia conference. The event also featuring the ASEAN Maritime Week, was opened by Malaysian deputy minister of energy, green technology and water. 

Russia and Iran have signed a wide ranging energy cooperation agreement that will see the two countries jointly build 8 thermal power plants in Iran. The Memorandum of Understanding signed on Tuesday provides for 2.8 GW of new generating capacity.

GE today launched its 9EMax gas turbine solution in Kuala Lumpur, which is hosting the Power-Gen Asia annual trade conference and Expo. "The 9EMax is nothing short of  game-changing solution for our 9E customers," Ramesh Singaram, Asia-Pacific President of GE's power generation business said.  The new turbine is expected to hit the market in 2016, Ramesh told Gas to Power Journal.

Output from power plants in Nigeria reached 4,044 MW this month, a two year high for the country, according to Nigeria's Minister of Power, Frank Edozien. The country has an installed capacity of 6,000 MW but power plants fail to produce maximum output  due to inadequate pipeline infrastructure restricting gas supply.

News in Brief

US geothermal power to quadruple by 2040

Sept 16 – Geothermal electricity generation in the U.S. could more than quadruple between 2012 and 2040 (increasing to over 67,000 GWh), helping California and other states with renewable portfolio standards satisfy their mandated renewable generation requirements, the EIA forecasts.

There are currently 64 operating conventional geothermal power plants in the United States, accounting for nearly 2,700 MW of total capacity at the end of 2013. Over three-fourths of U.S. geothermal power are in California, largely due to favorable geothermal resources, policy, and market conditions in the state.

 

Ground breaking for Coldwater gas power project

Sept 16 – A formal ground-breaking ceremony is being held today to lay foundations for three 4.4 MW gas turbines and generators to be delivered to a new gas power project near the City of Coldwater, feeding into the grid of Midwest Independent System Operators (MISO).

The power units came at a cost of $9.6 million and the City of Coldwater approved borrowing up to $16 million for the project, which is being built through the Michigan South Central Power Agency (MSCPA).

ABB wins $30 million order for gas-insulated switchgear (GIS)

Sept 15 - Swiss  manufacturer ABB has won an order worth over $30 million from Public Service Electric & Gas (PSE&G) to supply gas-insulated switchgear (GIS).

ABB’s order includes design, supply and commissioning of ABB’s 550 kilovolt (kV) GIS type ELK-3, a compact and modular solution that offers increased reliability and safety.

UK’s National Grid issues tender for additional reserves

Sept 15 – The UK’s National Grid has issued a tender for the supply of additional generation reserves this winter via the Supplemental Balancing Reserve (SBR) service.

Demand is driven by uncertainty over the availability of generating plants over the coming winter.

RWE to extend cost saving initiative

Sept 12 - German power producer RWE is to extend cost cuts at power plants due to tough market conditions.
