Smoother airfoil designs through Tomo-Lithographic Molding (TOMO) help improve the cooling capabilities of gas turbines and increase overall efficiency, Siemens representative Tim Rokita told Gas to Power Journal.

Flexible operation of Repsol's combined head and power (CHP) stations makes it difficult to optimize production costs. To alleviate uncertainties the operator developed and installed a real-time thermodynamic model, made up of 70 independent variables and over 900 functions or dependent variables, that controls operations of the CHP's three high-pressure boilers and one auxiliary boiler.

Japanese telecoms and energy provider SoftBank Group and American fuel cell producer Bloom Energy have formed a 50/50 joint venture, Bloom Energy Japan, to start selling distributed installations for base-load power. Bloom Energy Servers are based on gas-fired solid oxide fuel cell (SOFC) stacks, with a net base load power output of 200kW.

Wood Group GTS has completed a maintenance contract worth $2 million for Frame 5 and 6B gas turbines at power stations in Costa Rica and the US. 

Taking steps to enter the Chinese market, Alstom has signed a long term agreement to license its GT13E2 gas turbine for manufacture, assembly and sales in China through the Harbin Turbine Corporation (HTC).

Siemens is contracted to provide long-term service for Blackhawk Power Station – a 230-megawatt gas-fired cogeneration facility located in Borger, Texas.

Californian consumers could save up to $890 million per year, or 11 % in system level generating costs, by replacing 5.5 GW of gas turbines with an equal amount of Smart Power Generation (SPG), a KEMA DNV study finds.

GE is celebrating "20 years of powering progress around the world" as its LM6000 aeroderivative gas turbine that achieved more than 26 million operating hours.

Dehumidification is key for keeping a mothballed power station operationally ready while protecting it from corrosion or degradation during its temporary closure, says Carl Webb who worked with Andrews Sykes when Barking Power Ltd. temporarily closed one 500MW unit at its gas-fired power plant.

News in Brief

Wärtsilä wins contract in Barbados

Jan 24 – Barbados Light & Power Company Ltd (BLPC) has contracted Wärtsilä to fast-track the supply of a 33 MW flexible power plant, as an EPC project. The plant, set to run on four Wärtsilä-32 engines, will be built at a site adjacent to BLPC’s 10 MW solar photovoltaic plant at Trents, St. Lucy, located on the northwestern coast of Barbados.

Azito power plant takes FID

Jan 23 – Globeleq and IPS have reached financial close on a 253 MW expansion of the Azito gas-fired power plant near Abidjan. An MXL3 upgrade will boost the capacity of the combined-cycle plant from 460 MW currently to 713 MW, equaling about 30 percent Ivory Coast’s total capacity installed.

Climate risks become urgent

Jan 22 – Adaptation to climate change is now “urgent,” McKinsey claims, suggesting there would be “many adaptation opportunities.” Climate science shows that the risk from further warming can only be stopped by achieving zero net greenhouse gas emissions through renewable built-out and energy storage.

India’s electricity demand may triple, IEA finds

Jan 21 – Energy demand in India is set to double by 2040, and its electricity demand may triple, according to the International Energy Agency (IEA). Oil consumption in India is seen grow faster than that of any other major economy, making energy security a key priority, the IEA said in its first in-depth review of India’s energy policies. Amid strong growth, renewables now account for almost 23 percent of India’s installed capacity, while energy efficiency improvements helped avoid 15 percent of India’s additional energy demand, oil and gas imports, and air pollution.

Regulators approve CCGT in Wisconsin

Jan 20 – State regulators have approved a permit for Dairyland Power Cooperative to build a $700 million combined-cycle gas power plant in northwestern Wisconsin. The Nemadji Trail Energy Center will produce 625 MW and is scheduled to begin operations by 2025.

ExxonMobil enhances turbine oils

Jan 17 – New high performance turbine oils, developed by ExxonMobil Lubricants, are  entering the market which are formulated to prevent build-up of lacquer, varnish and deposits. The oils are designed to protect against thermal and oxidative degradation, one of the root causes of deposit build-up.

Wärtsilä signs O&M deals in the Bahamas

Jan 16 – Following the commissioning of a Wärtsilä-built 132 MW power plant in Bahamas in December, the Finish manufacturer now signed a two-year operation and maintenance (O&M) accord with the plant owner, the Bahamas Power and Light Company (BPL). Wärtsilä will transition, train, and develop the owner’s Bahamian work force and provide key performance guarantees.

China, S'Korea curtail coal to tackle air pollution

Jan 15 – Beijing city government’s aggressive approach to tackling air pollution is working and South Korea’s spring coal-fired curtailments show some success in cutting seasonal emissions. According to Wood Mackenzie, this should benefit LNG, particularly while spot prices remain low.

Sri Lanka at brink of power shortages

Jan 14 – Sri Lanka could face power cuts by March, after plans for a large-scale coal power plant were been cancelled just prior to start of construction, and a tender for a 300 MW diesel plants ended up in court. On the demand side, pressure is building up as the region is moving into the dry season in February and March. Weather warnings say the island is likely to receive lower than average rainfall in the first quarter of 2020.

This bullish price sentiment will feed through to oil-indexed natural gas contracts and LNG deliveries, linked to the Japanese crude cocktail (JCC) basket price.

IEA says coal’s fate tied to Asia

Dec 23 – Rapid rise of wind and solar power in many parts of the world has pushed coal-fired power generation into steep decline in most developed countries. "But this is not the end of coal, since demand continues to expand in Asia," analysts at the International Energy Agency commented: "The region’s share of global coal power generation has climbed from just over 20 percent in 1990 to almost 80 percent in 2019, meaning coal’s fate is increasingly tied to decisions made in Asian capitals."
