GE targets Africa with PowerXpand products


GE has introduced its PowerXpand Portfolio which is designed for companies looking to address temporary power needs or in search of permanent power “in a pinch”.

The portfolio consists of GE’s TM2500 and TM2500+ mobile aeroderivative gas turbine generator sets, the Jenbacher J320 containerised gas engine generator set and the V250/V228 diesel engine generator sets.

Darryl Wilson, president of aeroderivative gas turbines for GE Power & Water, said: “Our PowerXpand portfolio is ideal to provide a base load bridge to permanent power, for generating backup power to support natural disaster relief, plant shutdowns or equipment maintenance or for overcoming generation constraints such as hydropower shortages.”

In April 2011, Greece’s EXPO Power Systems purchased a TM2500+ gas turbine generator set to meet the summer peak power needs of the electricity grid on the island of Rhodes.

The Rhodes TM2500+ gas turbine generator set was commissioned within 11 days of arrival and ready to provide a fast, permanent source of power generation.

GE says the PowerXpand portfolio is particularly relevant in Africa, where economic growth is leading to an increase in energy demand.

Total electrification rates for the continent, which vary from country to country, still sit well below 50 per cent.

In many areas where energy is available, aging infrastructure and limited energy production capacity often make the electricity unreliable. Many power producers on the continent are searching for rapid, permanent power generation technologies that can solve their problems, such as those technologies in GE’s PowerXpand portfolio.

MHI boxes clever with power system in container

Mitsubishi Heavy Industries has completed the development of a transportable power generation system driven by a gas engine and designed like a shipping container.

MHI said the Meganinja is based on a concept of “quick transport, quick installation and quick generation” and as such can be up and running within 24 hours after arrival at its site.

The company believes primary demand for the product will come from emerging economies where power shortages remain common in some regions and for emergency power generators.

Inside the 12-metre long container is all equipment necessary for power generation, including a gas engine, generator, fuel gas compressor and control panel.

The unit can also accommodate cogeneration through simultaneous use of a container for waste heat recovery incorporating a hot water heat exchanger and exhaust gas steam boiler.

Both types of container can be transported to their destination by trailer.

The Meganinja has a generation output of 1500 kW and multiple units can be easily interconnected to expand output further.

Conventional stationary generating equipment requires time-consuming installation work, often up to a month while foundations and pipe and wire connections are made, but MHI stresses that the Meganinja “merely needs to be brought to its installation site, where it normally can be made ready to operate within 24 hours”.

MHI has already signed a deal with China’s Dongguan Xinao Gas Company for two units of the Meganinja.

MHI is also due in October to finish building a new engineering centre in Shanghai specifically for gas engine distributed power generation. The centre is intended to respond to growing demand for distributed power generation systems in the Chinese market.

Alstom Thermal clinches Saudi plant deal

Alstom Thermal Power has signed a contract worth over €100 million ($123 million) with Arabian Bemco Contracting to provide the steam tail for the Riyadh PP12 gas fired power plant being constructed by them for the Saudi Electric Company.

The Riyadh PP12 plant is located 100 km west of the Saudi capital. Once completed, the plant will produce a net output of 2175 MW at high temperatures with high efficiency.

The plant utilises exhaust gases from the gas turbines to generate steam and run the steam turbines, maximising the fuel utilisation with a highly efficient combined cycle design. The plant is scheduled to be operational by 2015 in order to meet the increased demand expected in the central region.

This contract includes the supply of two 342 MW steam-turbine generator sets and eight heat recovery steam generators for the power plant.

FG Wilson in $38m expansion

Gas and diesel genset manufacturer FG Wilson has invested €31 million ($37.9 million) to significantly grow its production capacity and boost facilities at its global engineering centre of excellence.

The company made the investment to exploit further growth in emerging markets across Africa, the Middle East, China and South America. A total of €26 million was invested in the engineering centre of excellence, which already contains a world leading hemi anechoic chamber providing state of the art acoustic research and testing capabilities. This investment has enhanced FG Wilson’s ‘best-in-class’ pre-production validation testing, which has resulted in significant product quality improvements and reductions in warranty claims.

Further investment saw the transformation of a 47 000 square foot assembly line into a continuously moving automated process, at a cost of €5 million.
