RTE in first European trial of Nexans’ conductor design
France’s electricity transmission system operator RTE is field testing a new type of overhead power line using Nexans’ carbon fibre composite technology – the first time this conductor design is being deployed in Europe.
If the trial – in Haute-Vienne in the Limousin region – is successful, Nexans says it will “provide TSOs with opportunities to adapt their high- and extra-high voltage networks to meet the needs of tomorrow’s energy landscape for redistribution of power generation, especially with the development of renewable energy resources”.
The field trial utilizes Lo-Sag conductor technology, which uses a carbon fibre composite core, and involves about 1 km of high voltage, 90 kV, overhead line being upgraded between Bellac and Saint-Martin-Terressus.
The three-phase trial installation replaces older steel cables while making use of most of the existing infrastructure such as pylons. Nexans says this is possible because of the light weight and low expansion of the new conductors.
Nexans says comprehensive testing of the Lo-Sag technology will take place throughout the course of the year, with the objective of “checking compatibility with the existing grid as well as reviewing its mechanical properties and the capability to withstand France’s variable climate, including combinations of wind, ice and snow”.
The conductor for trial was manufactured at Nexans’ factories in France, Belgium and Germany.
Wartsila wins deal for Indonesia’s biggest gas plant
Wartsila has won a contract to provide the engineering and equipment for what will become the largest gas engine-based peaking power plant in Indonesia.
Construction of the 184 MW Arun plant in Lhokseumawe in northern Sumatra is already underway on a fast-track basis and is scheduled to be handed over and in full operation in March 2015.
The order has been placed by Wijaya Karya, a government-owned company and one of Indonesia’s biggest construction contractors, which is building the plant for state utility PLN.
The plant will operate on 19 Wartsila 34SG engines running on liquefied natural gas. Sushil Purohit, Warstila Power Plants’ regional director for South-East Asia said.
“When completed, the Arun gas power plant will be able to strengthen the Aceh electricity system and will support PLN’s effort to bring reliable electricity to consumers. The Arun contract is Wartsila’s second from Indonesia this year.
The first was booked in the second quarter for a 155 MW gas engine based peaking plant also owned by PLN.
Wartsila will supply 16 of its 34SG engines to the plant in Bangkanai in Central Kalimantan, which is scheduled to be fully operational by the end of 2014.
FG Wilson completes $188m Egyptian genset contract
FG Wilson and its authorised Egyptian Dealer, Triangle Heavy Equipment, have completed a $188m generator set contract for a new business, leisure and residential complex in Cairo.
Cairo Festival City features 700,000 sq m of office space, 217,796 sq m of retail and leisure space, luxury living communities, hotels, schools and a theme park. It is due to be completed in 2018, when it will be home to over 13,000 residents and a workplace for 50,000 more.
Located 15 minutes from Cairo International Airport, the facility is owned by Al-Futtaim Group Real Estate and is being built by Al-Futtaim Carillion and Orascom.
Triangle installed 15 FG Wilson gensets, ranging from 44 kVA up to 550 kVA, which will provide power to water and sewage plants, four office blocks and the theme park, as well as to on-going construction sites. All the gensets are providing back-up power, apart from those at the construction sites which are providing prime power.
Fred. Olsen Renewables buys Scottish wind project
Fred. Olsen Renewables has acquired total ownership from RWE npower renewables of Brockloch Rig Wind project in Scotland.
The company already owned half of Brockloch Rig, under which it had built one wind farm, Windy Standard, and it has now acquired the other 50 per cent from RWE.
Fred. Olsen Renewables will now press ahead with the development of two further wind farms – Windy Standard II and III.
Both projects will be located in the hills above Carsphairn Forest in Dumfries and Galloway, with construction of the first due to start in the middle of next year.
Fred. Olsen Renewables chief executive David Brunt said: “The acquisition of the remaining share of this project is important for us, further building our UK portfolio and demonstrating our commitment to deliver renewable energy while actively co-operating with key stakeholders and local communities.”
When operational, Phase 1 of Brockloch Rig will bring Fred. Olsen Renewables’ portfolio to just over 487 MW of operational wind farms in the UK.”
Fred. Olsen Renewables currently has an onshore wind portfolio of over 428 MW in operation, of which 357 MW is in Scotland equivalent to 8% of the country’s total onshore installed wind capacity or 5% of the UK’s total onshore installed wind capacity. A further 112 MW of onshore wind plant, including Brockloch Rig, is either under construction or due to shortly enter construction in the UK.
Fred. Olsen’s overall strategy is to participate in projects from an early stage. The company is involved in site selection, planning and construction and aims to operate the projects over their lifetime. The approach is based on a successfully demonstrated full lifecycle principle.
The first phase of the project was consented in 2007 with a planned installed capacity of up to 75 MW. Construction on Windy Standard II is due to commence in mid-2014 with pre-construction activities already underway. Windy Standard III is a proposed development of up to 43.5 MW.
Siemens to replace old coal facility with CHP plant in Poland
Siemens Energy is to replace an old coal-fired power plant in Poland with a facility that will produce 95 per cent less sulphur dioxide emissions, more than 30 per cent less nitrogen dioxide emissions and more than 95 per cent less particulate emissions.
The company has been awarded a contract by utility PGE GiEK to build a turnkey cogeneration plant in western Poland.
The Gorzow plant in Gorzów Wielkopolski will have an electric capacity of 138 MW, a thermal capacity of 90 MW and an efficiency rating of 84 per cent.
The order value for Siemens, including a long-term service agreement for the main components, is about $215m and commissioning is planned for early 2016.
As part of the agreement, Siemens will deliver two SGT-800 gas turbines, one SST-400 steam turbine, three 11 kilovolt (kV) generators and two heat recovery steam generators. The deal also includes a long-term 12 years maintenance agreement for the gas turbines. The Gorzów plant will be fired with nitrogen-rich natural gas from gas reserves located in western Poland. This type of gas has a lower calorific value than conventional natural gas.
“We chose the Siemens solution because their plant offers a very high efficiency, so that it can generate electricity at a very affordable cost,” said Jacek Kaczorowski, chief executive of PGE GiEK. “The district heating makes the plant even more economical. Furthermore, we can use our local natural gas reserves to fire the turbines.”
GE hails wind turbine output breakthrough as ‘the next evolution’
GE says its new 3.2-103 Brilliant wind turbine has delivered a 5 per cent increase in energy output compared to its current model.
Cliff Harris, general manager of Europe for GE’s renewable energy business, said the 3.2-103 “is the next evolution in our European product platform”. He said the turbine had been engineered specifically for UK and Ireland permit constraints.
“The 103-meter rotor diameter and hub-height flexibility make it an excellent fit for height constrained sites.
The turbine analyses tens of thousands of data points every second and “integrates energy storage and advanced forecasting algorithms while communicating with neighboring turbines, service technicians and operators”.
