Wärtsilä wins power plant operation contracts in Brazil

Wärtsilä has been contracted to operate and maintain the Geramar I and Geramar II power plants in Miranda do Norte, Brazil.

Both plants are located on the same site, and are each supplied with 19 Wärtsilä 20V32 engines. The plants will generate a total of 320 MW of electrical output to the national grid.

This five-year operation and maintenance (O&M) agreement means that Wärtsilä will take full responsibility for the efficient operation of the plant, and for all service and maintenance functions. It is estimated that the contract will result in the creation of approximately 60 new jobs for the local population.

“In Brazil, Wärtsilä is now responsible for operating and maintaining 12 power plants in various parts of the country. Together it means that a total of 1 GW of electrical output is run by the Finnish company. This impressive figure is a strong reference to our ability for ensuring safe and reliable operating performance under a variety of conditions,” says Gil Viana, general manager, service Sales, Wärtsilä in Brazil.

The two Geramar plants are scheduled to be fully operational in January 2010. The contractor for the two plants, Geranorte, is a Brazilian consortium made up of Equatorial Energia, the Brasil Energia Investment Fund and GNP.

Wärtsilä O&M agreements are tailored to the needs of its customers to give real added value. The agreement programme is designed to cover all aspects of operating and managing an installation, including O&M planning, day-to-day operations, scheduled and unscheduled maintenance, administration, human resources and training, technical support, logistics management and security. The Finnish firm said that this comprehensive programme enables the plant owner to focus on the company’s core business.

ENER-G’s triple Baltic energy-from-waste success

Energy users in Lithuania will soon be plugging into 5.5 MW of green electricity – generated by renewable power technology from the British ENER-G’s Natural Power business.

The latest project will enable the municipality of Alytaus in southern Lithuania to generate 1 MW electricity from its landfill waste disposal facility à‚— becoming the third area in the country to convert environmentally unfriendly landfill gases à‚— 21 times more harmful to the environment than carbon dioxide (CO2) à‚— into electricity. This follows similar contracts with the Regional Waste Management centres in the capital city of Vilnius and Klaipeda on the western Baltic coast.

Construction of the Vilnius contract for a 3 MW landfill gas generation project and a 1.5 MW landfill gas generation operation for the Waste Management Centre of Klaipeda will be completed later this year.

ENER-G Natural Power’s managing director Hugh Richmond met recently with the Lithuanian minister of environmental protection, Gediminas Kazlauskas, to tell him about the ENER-G group’s activities in his country and he was delighted to hear about the technology, skills transfer and the creation of employment in the energy/environmental sector.

ENER-G’s capital investment of more than à‚£5m ($8m) in the three sites is said by the Lithuanian government to be among the highest to be made in the country by a British business. “This is an auspicious start to our activities in Lithuania, which hopefully will extend to other offerings from the ENER-G group, not just in Lithuania but also the other Baltic countries of Latvia and Estonia,” said Richmond.

ENER-G further underscored its growth in northeastern Europe this Summer with the opening of new offices in Poland. Situated on the third floor of a modern new building in Warsaw, the new premises comprise 280 m2 of office space and accommodates 20 people.

The move has added ENER-G’s combined heat and power, and energy management technologies and services to the company’s ongoing landfill gas generation operations. ENER-G began operations in Poland six years ago and has grown its Polish business organically, from start-up to a highly successful company with a turnover of 85m zloty ($29m) this year and 30 employees.

Work will start on the Alytaus landfill development later this year, with some generation expected by the end of 2009. “All contracts involved competitive tendering so we are very proud of the fact that we have successfully competed in this market,” said Richmond. “It should be emphasized that ENER-G worked very closely with a local consultancy, Proto Paslaugos and in particular its director, Irmantas Sidlauskas, who was instrumental in our success.”

Landfill gas can be profitably harnessed using ENER-G’s unique modular engine system. This enables local authorities and waste companies to maximize resources by matching capacity to the gas production of the site.

The system uses methane to power internal spark ignition engines with a capacity of 1 MW to 3 MW, which generate electricity that is fed into the local grid.


The article ‘Australia fast-tracking the development of IGCC with CCS’, published in the September 2009 issue of Power Engineering International, mentions that the ZeroGen project has been endorsed by the Electric Power Research Institute (EPRI) in the US.

This statement is incorrect because the EPRI does not endorse any technology or project over another.

The EPRI is an independent, non-profit organization that conducts research and development relating to the generation, delivery and use of electricity for the benefit of the public.

The SGT-800 gas turbine-generators, each rated at 47 MW, will be operated in the Tuapse refinery located on the Black Sea. The first three gas turbines are scheduled for delivery by late 2010, with the remaining three units to follow by the end of 2012. The order is valued at approximately €90m ($131m).

The order encompasses six gas turbines and six generators that are needed for the generation of electricity and steam to accommodate expansion of the Tuapse refinery’s capacity. Tuapse is an important petroleum port on the Black Sea.

The customer OOO RN-Tuapsinskiy NPZ is currently undertaking extensive expansion and upgrading projects at the refinery to increase the plant’s capacity from a current 5m to about 12m metric tonnes (38m to 88m barrels). At the same time refining depth will be increased from 56 per cent to 95 per cent.

“Being able to offer both gas turbines and generators together allows us to uniquely optimize our oil and gas power solutions,” said Tom Blades, CEO of the Oil & Gas Division at Siemens Energy. “We have already obtained several gas turbine orders from Rosneft. This highlights our strong cooperation with the customer as well as the impressive characteristics of the combination of Siemens gas turbines and generators in terms of efficiency, reliability, and quality.”

Siemens claims that the SGT-800 marries efficiency, high availability and reliability with low life-cycle costs. NOx emissions are minimized thanks to its Dry Low Emissions (DLE) combustion system. A critical project requirement for the gas turbines being supplied to the Tuapse refinery is their capability to operate on various fuels. The SGT-800’s DLE system can also achieve low emissions on a wide variety of fuels.

Including this order, 29 SGT-800 gas turbines have already been ordered by customers from Russia or have been delivered to Russia. For instance, between 2007 and 2008 Siemens received orders from Rosneft for a total of seven SGT-800 machines for the gas turbine power plant at the Priobskoye oil field.

In June 2009, the Kolomenskoe gas turbine power plant in Moscow, with three SGT-800 machines supplied by Siemens, was commisioned. The cogeneration power plant supplies 136 MW of electricity and 171 Gcal/h of district heat at 83 per cent efficiency.

Australia’s Queensland inaugurates on-site plant powered by Jenbacher waste coal mine gas engines

Queensland’s minister for mines and energy, Stephen Robertson has formally opened one of Australia’s most powerful on-site power plants fueled by waste coal mine gas (WCMG).

The 45.6 MW alternative energy plant, located at Anglo Coal’s Moranbah North mine in the state of Queensland, allows the operator to capture the mine’s methane-rich gas and use it as a fuel to generate electricity instead of venting the gas into the atmosphere. The plant is powered by 15 of GE Energy’s ecomagination-certified, 3 MW J620 Jenbacher gas engines.

“Our successful project at Moranbah North illustrates the importance of using proven technologies like GE’s Jenbacher gas engines and relying on experienced alternative energy services partners like Clarke Energy to help Australia achieve its emissions reduction goals,” said Greg Pritchard, managing director of Energy Developments Limited (EDL).

Anglo Coal is one of the country’s largest coal mining companies. The Moranbah North mine is located 1117 km north of Brisbane. The new cogeneration plant offers Anglo Coal an important environmental benefit because methane has 21 times the greenhouse warming potential of carbon dioxide (CO2), the greenhouse gas most closely associated with climate change.

GE’s Jenbacher combined heat and power technology also allows the operator to use an available source of fuel to help reduce its operational expenses.

Through the capture and utilization of mine gas, the Moranbah North project will deliver significant environmental and energy security benefits. The distributed energy plant will save up to about 1.3m tonnes of CO2 equivalents, or the average of taking 330 000 cars off the road each per year.

EDL, owner and operator of the plant, will sell most of the plant’s 45.6 MW output to the national grid.

EDL had designated Clarke Energy Australia to install GE’s Jenbacher units as part of a turnkey contract. Clarke Energy Australia is a subsidiary of Clarke Energy Group and GE’s long-time Jenbacher authorized distributor in the UK. The overall power station design, balance of the plant, SCADA controls and turnkey construction were provided by Clarke Energy Australia.

The WCMG plant was completed seven weeks ahead of schedule and within budget to meet EDL’s aggressive schedule as a growing number of Australian mining companies are seeking to utilize its mine gas to generate electricity and reduce their site emissions.

Australia, which exports nearly 75 per cent of its coal resources, now has one of the world’s most commercially advanced coal mine methane gas industries, according to the Australian Coal Association.

GE’s Jenbacher gas engine technology is designed to be flexible to also handle fluctuating gas qualities à‚— a longtime industry obstacle à‚— allowing the utilization of gas from both active as well as closed sections of mines.

Through Clarke Energy, GE has supplied its Jenbacher engines for most of Australia’s WCMG projects, demonstrating the environmental benefits and reliability of the engines.

BHEL receives Belarus plant order

Indian power engineering major Bharat Heavy Electricals Limited (BHEL) has received a power plant equipment export contract valued at INR2.7bn ($58m) from Grodnoenergo, a state-owned enterprise in Belarus.

The gas turbine-generator set with dedicated auxiliaries, compressors, heat recovery boiler, boiler auxiliaries and automatic process control system for the Grodnoenergo project will be supplied from BHEL’s manufacturing units at Hyderabad, Tiruchirapally, Ranipet and Bangalore, respectively.

The Indian giant has identified the CIS region as one of the potential regions for enhancing its overseas business.

The company has also signed a memorandum of understanding with TGR, based in Hungary, for exploring opportunities for conventional boilers, and repair and maintenance of boilers in European and CIS countries.

MTU unveils latest diesel engines

MTU Onsite Energy, a leader in distributed power solutions, introduces its newest diesel-powered generator set covering a range of 250 kW to 600 kW.

The new genset is based on the MTU Series 1600 engine, through which MTU’s proprietary power range is extended from as low as 250 kW up to 3250 kW. The company claims that the new series features a well-built, stable engine.

Series 1600 engines, from 12 V to 6-cylinder inline, will offer an advantage in covering power nodes that were previously sourced from two different engine manufacturers.

The design not only offers greater flexibility, but it also gives the genset a well-packaged look with very clean lines. The Series 1600 engine is a completely new engine for MTU and is the smallest engine that the company produces.

The manufacturer claims that the new 1600 series has all the hallmarks of an MTU engine: exceptional reliability, high power density and fuel efficiency. When combined with the completely new design of the generator set package, the result is a compact powerhouse that is ideal for emergency standby and peak-shaving applications.

The Series 1600 generator sets also have an improved electrical stub-up compared to similar gensets powered by other engine types.

The new design allows ample room for connecting cables in the stub-up area, thus making installation easier. Another design advantage is in the mounting of the outlet box.

Whereas previous generator set designs mounted the outlet box to the barrel of the alternator, the Series 1600 outlet box is mounted directly to the base of the genset. This significantly reduces the amount of vibration to which the outlet box is subjected, which has a positive effect on the life of the electrical system.

Generator sets based on the 12 V configuration of the Series 1600 are currently available in 550 kW – 600 kW power nodes. MTU Onsite Energy has already received several orders for the Series 1600 generator sets, the first of which are scheduled for delivery in December.
