Parker Hannifin technology was at the heart of managing power fluctuations and helping to prevent outages throughout the Olympic Winter Games in Sochi.
Working in partnership with EnerDel, a leader in utility-scale lithium-ion battery energy storage systems, Parker Hannifin supplied one of its power conversion system solutions as part of a 1.5 MW installation connecting large banks of battery energy storage to the grid, smoothing out fluctuations and supplying backup power for the local substations that supported the games.
The system included Parker’s precision cooling technology, which increases the throughput of high power electronics by up to 40 per cent. Parker also provided other ancillary equipment such as outdoor battery enclosures, complete with climate control, fire suppression and monitoring systems.
ABB in $55m submarine cable deal for UK offshore windfarm
Swiss firm ABB has won a $55m deal for a submarine power cable system which will link an offshore wind farm with the UK grid.
The alternating current (AC) cable will be used at the 400 MW Dudgeon offshore wind farm, which is owned by a joint venture between Statoil and Statkraft, which are also building Sheringham Shoal offshore wind farm in Britain.
Dudgeon’s turbines will be located in waters 18–25 metres deep, around 32 km off the coast of Norfolk on England’s east coast.
ABB will design and supply two 132 kV three-core AC submarine cables, each 42 km long, running from the wind farm’s offshore substation to land, where they will connect to onshore cables. The submarine cables will be manufactured at ABB’s high-voltage cable factory in Karlskrona, Sweden, and delivery will start in 2016.
Claudio Facchin, head of ABB’s power systems division, said: “Offshore wind is a growing renewable energy resource, with Europe accounting for around 70 per cent of new offshore wind generation capacity. Transporting electricity from offshore wind farms to the shore and then integrating it into the grid for supply to consumers are key elements.”
Bjorn Ivar Bergemo, asset manager of the company Dudgeon Offshore Wind Farm, said the cables “will be some of the longest ordered so far for a UK offshore wind project”.
The wind farm is expected to produce enough electricity to power 250 000 homes in the UK each year.
Samsung wins $1.37bn twin combined cycle contracts in Algeria
Samsung C&T has won a $1.37bn contract to build two combined-cycle gas-fired power plants in Algeria.
The engineering, procurement and construction contract has been awarded by Sonelgaz Electricity Production Company and the contract covers construction of two power facilities in Mostaganem and Nama.
The Mostaganem station is expected to have a generating capacity of 1450 MW, while the Nama facility will have 1163 MW upon its completion.
Algeria’s government plans to build six new combined-cycle power plants by 2017 to address growing demand for electricity.
Rwandan PV plant marks solar first for East Africa
A solar power plant is to be built near the Rwandan capital, Kigali. It will be the first utility-scale solar plant in East Africa.
The $24m, 8.5 MW solar photovoltaic project is expected to boost Rwanda’s electricity supply by 8 per cent once it starts operating this year.
The project is being developed by Energiya Global Capital group, which has provided seed capital. Chief executive Yosef Abramowitz said he hoped the project would prove that commercially viable solar plants can be built throughout Africa, where 550 million people lack access to electricity.
The Rwandan solar plant is being financed by a consortium of equity investors and debt providers including Dutch development bank FMO, Norwegian development body Norfund and the Emerging Africa Infrastructure Fund (EAIF). It also received grants from bodies funded by the governments of the UK, Finland, Austria and the US.
The plant’s electricity will be fed into the national grid under a 25-year power purchase agreement with the Rwanda Energy, Water and Sanitation Authority. Commercial operation is expected to begin this summer.
The Rwandan government is aiming to connect half its population of 11 million people to electricity by 2017 and also reduce dependency on diesel-powered generation and the hydropower plants that provide most of its capacity.
Brazil, Japan and Saudi consortium wins approval for 600 MW coal plant in Mozambique
Mozambique’s government has given the go-ahead for the construction of a 600 MW coal-fired power plant in Moatize in the western province of Tete.
The $1bn project will be run by Acwa Power Moatize Termoelectrica, a consortium whose main shareholders are Acwa Power of Saudi Arabia, Vale of Brazil and Mitsui of Japan. There are two Mozambican minority shareholders – the Whatana Investment Group, which holds an 8 per cent share, and the publicly-owned electricity company EDM, which holds
5 per cent.
The power plant will be built at the mouth of an opencast coal mine operated by Vale in Moatize.
The project will be built in two phases. The first phase will generate 300 MW with about 200–250 MW to be used by Vale itself to run its mining operations, while EDM will take the remaining power, adding it to the national electricity grid.
The addition of the plant will increase the energy capacity of the country from its current 2000 MW. Most electricity is currently generated by the Cahora Bassa hydroelectric dam on the Zambezi River.
Progress installs over 60 gensets for STOR solution in UK
The Progress Group, part of FG Wilson’s global network of dealers, has completed short-term operating reserve (STOR) installations at three different sites across the north of England for the UK’s National Grid.
STOR is designed to offer backup to
balance supply and demand on short timescales that could not be achieved with conventional large-scale power during significant spikes in demand or failures of existing production.
In total there are 61 FG Wilson generator sets across the three sites in Yorkshire, Lincolnshire and Nottinghamshire, comprising a mix of P1875 and P550 gensets – each specifically arranged and customized to meet the individual project requirements.
Phil Starr of the Progress Group said: “With an unusually large number of generator sets involved in each project, devising a control system capable of effectively synchronizing the units was vital to the overall success of the installations.
“It is somewhat unusual for so many generator sets to be installed at one site and this provided a major challenge in designing a synchronizing control panel. The STOR sites are in rural areas which required us to pay particular attention to noise regulations as well as paying due heed to the impact on the local environment.”
