Cogen plant marks milestones for France and GE

Cogen plant

A landfill gas-fueled power plant believed to be the most powerful in France has been inaugurated in Plessis-Gassot.

The opening also marks the first time a town in France has had a district heating scheme fuelled by biogas.

The facility was developed by Véolia in co-operation with Dalkia and Clarke Energy, and features 10 of GE Distributed Power’s Jenbacher gas engines to generate renewable electricity and heat for residents and businesses.

The new cogeneration plant replaces a smaller, less efficient steam turbine-boiler system. GE says it uses the landfill’s methane-rich biogas to generate enough renewable electricity to power more than 41,000 homes.

The electricity is sold to àƒâ€°lectricité Réseau Distribution France (ERDF) for use by residents and businesses throughout the country.

In addition to electricity, the facility also produces 30,000 MWh/year of thermal energy, which is feeding a new heating and hot water network. Installing GE’s gas engines increased the power output of the landfill gas plant by 5 MW while also raising its electrical efficiency from 22 per cent to 40 per cent.

The new plant consists of 10 Jenbacher units – four 2.7 MW J620 gas engines, five containerized 1.1 MW J416s and one containerized 1 MW J320.

The project also represents the first installation of GE’s Jenbacher Type 6 landfill gas engines in France. Karl Wetzlmayer, general manager for gas engines at GE Power & Water Distributed Power, said: “As the largest landfill gas power plant in France and the first installation of our Type 6 technology for landfills in France, this project demonstrates how our fuel-flexible Jenbacher gas engines can provide more power with increased efficiency.”

Metso wins waste-to-energy deal in UK


Finnish automation solutions company Metso has signed a deal with Babcock & Wilcox Vàƒ¸lund to supply automation for a waste-to-energy plant in the UK.

The new plant in Peterborough will be operated and maintained by major European waste management company Viridor and is scheduled to be completed in 2015.

Denmark-headquartered Babcock & Wilcox Vàƒ¸lund is responsible for the engineering, procurement and construction of the plant, which will have a capacity of 7.25 MW and will handle approximately 85,000 tonnes of waste per year.

Metso will deliver a DNA automation system, a DNA information management system and a fully integrated DNA machine monitoring solution to predict mechanical faults in critical machinery.

Neil Buckland, sales director of UK Automation for Metso, said the contract builds on Metso’s experience in waste-to-energy plants in the UK: “Our Metso DNA automation system is installed in 60-70 per cent of the UK’s energy-from-waste plants.”

Alstom hails HVDC link as South Korean milestone


Alstom Grid has completed a “first of its kind” 400 MW high voltage direct current turnkey project in South Korea.

The bi-directional transmission line links Jindo and the island of Jeju and is the second such project delivered by Alstom Grid in the country following a 300 MW link between Jeru and the mainland in 1997.

Patrick Plas, senior vice president of Power Electronics & Automation for Alstom Grid, said: “This second project, first of its kind at a power capacity of 400 MW in South Korea, demonstrates Alstom’s efficient commissioning management, and commitment to continuous innovation in high voltage energy management.”

The International Energy Agency ranks South Korea eleventh worldwide in power consumption, yet it imports 82 per cent of the total energy it consumes.

Jeju Island is 100 km south of the mainland and is 73 km wide and 41 km long. It previously operated on an independent electric network and suffered frequent blackouts and unstable power supply due to the network’s lack of efficiency and low power capacity.

Alstom said its HVDC technology is “well-aligned with Korea’s ambition for a low-carbon economy and is essential to carrying large amounts of power across long distances, with minimal losses”.

The new HVDC link is designed to be bi-directional so that renewable power on Jeju Island will be integrated for mainland use.

Noja Power plays part in World Cup energy team

Australian company Noja Power provided technology at many of the venues for June’s FIFA World Cup in Brazil.

The electrical switchgear firm has supplied its OSM series automatic circuit reclosers (ACR) at several stadiums.

The OSM15 ACRs were installed in Castelàƒ£o Stadium which hosted six of the tournament’s games.

The ACRs, which have a maximum rated voltage of 15.5 kV and a rated continuous current of 800 A, are used in an auto change over (ACO) configuration to ensure continuity of electricity supply. One ACR is fitted to the stadium’s primary feeder with an additional unit on a secondary feeder. In the event of a problem with the primary feeder, the ACR opens to isolate the line, while the second unit automatically closes to activate the secondary feeder to supply stadium power while the primary line is repaired.

OSM15 ACRs were also installed this year to provide overcurrent protection for the training centre of the Italian team in Mangaratiba, near Rio de Janeiro, while OSM27 ACRs provided overcurrent protection for feeders of several stadiums in Belo Horizonte which were used as training camps for the teams from Argentina, Uruguay and Chile.

Bruno Kimura, managing director of Noja Power Brazil, said: “The 2014 FIFA World Cup and the 2016 Olympic Games in Rio de Janeiro will focus the eyes of the globe on our country. It is therefore very important that the facilities for these events are seen to be world-class. I’m pleased that Noja Power Brazil is performing an important part in this respect by providing the equipment that will help ensure reliable electricity supplies.”

Senvion installs Nordsee Ost wind turbines


Suzlon Group subsidiary Senvion has installed the first offshore turbines for the Nordsee Ost offshore wind farm.

The RWE project is located approximately 35 km from the island of Heligoland off Germany and is equipped with a total of 48 turbines, each rated at 6.15 MW.

After its completion in 2015, Nordsee Ost will have an installed capacity of approximately 295 MW, making it one of the largest commercial wind power projects off the German coast.

Senvion is supplying all components for the wind turbines and the service platform cranes. The hubs, rotor blades, nacelles, towers and other platform components are being preassembled as much as possible in a harbour at Bremerhaven and are then loaded onto special ships to be transported to the wind farm.

Doosan Heavy hails Rabigh safety milestone

Doosan Heavy

Doosan Heavy Industries & Construction’s construction office on the site of the Rabigh 2 power plant in Saudi Arabia has achieved 40 million hours of accident-free operations.

Doosan Heavy says that the milestone reinforces “the company’s commitment to outstanding safety performance across its power plant construction operations”.

The Rabigh 2 project, awarded to Doosan Heavy in 2010, involves the construction of a 2100 MW combined-cycle, gas-fired plant, which is expected to be completed in 2017.

The project calls for the simultaneous construction of four plants, with around 15,000 workers from 37 countries deployed daily, which Doosan says makes the safety record “all the more significant”. All four plants are currently operating to test output.

Doosan said: “Power plants entail a higher risk of industrial accident than conventional construction projects due to a number of factors, including the cultural diversity of the workforce employed and the equipment and facilities involved.

“To mitigate these risks, Doosan Heavy has implemented a series of Environment, Health & Safety (EHS) programmes that focus on providing workers with hands-on experience and help different cultures work together in a safe environment. The programme includes training workers for real accident situations; the operation of a daily safety patrol system; and awards for exemplary workers.”

Meanwhile, Foster Wheeler has won a contract to design and supply six heat recovery steam generators (HRSGs) for Rabigh 2.The deal was clinched by BHI, a licensee of Foster Wheeler’s global power group, and the six HRSGs will be coupled to six SGT6-5000F Siemens gas turbines firing natural gas and oil.

Woo Jong-Ihn, president of BHI, said: “We have executed a number of key projects in the Middle East and this award reinforces our position as a leading supplier in the region.”

Nordex seals trio of Turkish wind orders


German windpower group Nordex has clinched three orders for for a total of 44.4 MW in Turkey.

The company has said that because much of the equipment will be manufactured locally, it will qualify for higher feed-in tariffs (FiTs).

Under the terms of the three orders, Nordex will supply six Generation Delta N117/3000 turbines at the Urla wind farm in Izmir for Sancak Enerji; nine Generation Gamma N117/2400 turbines at the Yenihisar wind farm for Yeni Enerji; and two N117/2400 turbines for the Pitane wind farm in Izmir for Bicakcilar Enerji.

Nordex plans to start all three projects between spring and summer 2015.

The towers and some rotor blades are being sourced locally, which means all three projects will be eligible for higher FiTs, because if blades and towers are manufactured in Turkey the FiT of $7.3 cents per kWh is topped up with an additional $1.4 cents per kWh.

Zimbabwe swaps Chinese firms for $1.3bn coal plant

Zimbabwe has awarded a $1.3bn power project contract to a Chinese firm after cancelling a previous contract, the energy ministry has announced.

The contract to add two 300 MW units to the 900 MW coal-fired Hwange power station in northwestern Zimbabwe was first awarded to China Machinery Engineering Company (CMEC) in mid-2013, but the company failed to meet a design and construction timeline, the government said.

“CMEC failed to conclude the contract within the stipulated time frame that they had agreed upon with the Zimbabwe Power Company and the government of Zimbabwe, hence the tender was cancelled,” said energy and power development minister Dzikamai Mavhaire.

The contract has now been awarded to the second-highest bidder in the tendering process, Chinese EPC firm SinoHydro.

Zimbabwean paper NewsDay said CMEC was awarded the contract under “controversial” circumstances during the previous energy minister’s tenure.

According to the paper, CMEC’s bid was over $300m more than SinoHydro’s, which came in at $990m.

The Hwange plant currently operates at 63 per cent of its installed capacity.
