electrical substation

Abengoa has been selected by Compañia Minera Teck Quebrada Blanca S.A., part of the Grupo Teck Mining Inc., to develop the engineering, procurement and construction of seven 220 kV electrical substations for the second phase of the Quebrada Blanca mine in Chile. The project is worth approximately US$ 54 million.

The scope of the project contemplates engineering, procurement and construction (EPC) of seven electrical substations 220/23 kV and 220/6,9 kV for the port, pumping stations and concentrator, part of Quebrada Blanca Phase II, whose main objective is strongly to boost the mine´s copper production and extend the mine´s productive life in more than 30 years. The project also includes the support in all pre-operational tests and the start-up of the previously mentioned facilities.

Obtaining this contract further consolidates Abengoa’s position in large mining sector, where it has been operating for more than 30 years, and where it has developed significant electrical and electromechanical assembly projects.

It will be installed at the world’s largest offshore wind farm currently being built

Iberdrola and Navantia has marked the delivery of the offshore substation, christened as Andalucia II, entirely built at the shipyard of Puerto Real (Spain) and destined to Iberdrola’s East Anglia One offshore wind farm in the United Kingdom. Andalucía II, the largest AC offshore substation ever to be fabricated, will set sail over the next few weeks and will be installed at the site of Iberdrola’s offshore wind farm. With 714 MW total capacity and an investment of £2.5 billion, East Anglia One is the world’s largest renewable energy facility being built by a Spanish company.

Present at the event were José Esteban García Vilasánchez, Chairman of Navantia, Ignacio Galán, Chairman of Iberdrola and Susana Díaz, Head of Analusia’s regional government who christened the substation.

East Anglia One, a driver of job creation and economic development

East Anglia One offshore wind farm has become a key driver of economic development in all of the areas taking part in the manufacturing of the equipment and installation activities. As was the case with Wikinger, now operating in the Baltic Sea, Iberdrola awarded Navantia, together with some 30 specialised ancillary companies, the fabrication of a key element of the wind farm, its offshore substation.

After 16 months of work, the unit has been delivered according to schedule and has enabled the creation of approximately 450, mainly local, jobs, reaching 600 on peak working periods.

Innovation at the largest AC offshore substation

Andalucía II offshore substation is at the heart of the wind farm Iberdrola is building in British waters. Its role will be to collect the electricity generated by the wind turbines and transform the supply voltage from 66kV to 220 kV. Power will then be carried by the export cable to land, thus minimising losses along the route.

The topside, the world’s largest AC substation, includes design innovations developed by Iberdrola to make it more compact, bringing down is weight to 3,900 tonnes while facilitating handling by installation vessels.

In early August, the Andalucía II substation will be towed from Puerto Real to British waters with arrival scheduled for early September. Over the next few months, piles, jackets and topside will be installed on site alongside the rest of the WTG jackets.

East Anglia One will be commissioned in 2020 and will produce enough clean energy to power the consumption of nearly 600,000 UK homes.

Having pioneered the development of onshore wind, Iberdrola is leading the way of the renewable energy source with the largest growth prospects: offshore wind.

The company currently operates two offshore wind farms, West of Duddon Sands in the Irish Sea, and Wikinger, in the Baltic Sea and has a project pipeline of over 7,200 MW in the North Sea, Baltic Sea, French waters and the Northeastern US coast.

Iberdrola and Navantia have signed, in London, the contract to construct the electrical substation for the East Anglia 1 offshore wind farm in the UK. The scope of the contract includes the construction of one module, its jacket support structure, at the Puerto Real shipyard and the offshore support for its connection and commissioning in the North Sea.

The contract will involve an estimated workforce of on average 350 people, however there will be peaks of up to 600 over the next two years. The works will start shortly and will conclude in around 2 years’ time with the installation of the jacket and the module in the North Sea.

 

Navantia is expected to collaborate with and support Iberdrola over the coming months in the initial project phase, in the development of the engineering works as well as in other activities with the aim of guaranteeing delivery periods and the quality of the supplies from the main collaborators. Manufacturing will start next spring.

The East Anglia 1 wind farm is situated in the south-eastern area of the North Sea, some 45 km south-east of the town of Lowestoft and covers an area of some 300km2. East Anglia 1 comprises 102 wind turbines with a total installed capacity of up to 714 MW. The wind turbines will be assembled on jacket-type steel structures.

Navantia also has a pre-agreement in place, expected to be signed soon, to construct 42 jackets that will support the wind turbines. These parts will be manufactured at the Navantia shipyard in Fene, Ferrol.

The wind farm is equipped with an electric substation (OSS) and two AC circuits connected to an onshore substation in Bramford (north of Ipswich), adjacent to the existing National Grid substation. The module consists of four housings supported by 4 feet covering a surface of 22 x 26 m. The total estimated weight of the module is around 3,500 tonnes.

The total height of the jacket is 58 m, including 12 J-tubes for the cables array and a further 2 for the transmission cable. It will also be equipped with two boat landings so that vessels can moor to the substation. The total weight of the jacket structure is approximately 2,400 tonnes and that of the 4 piles is 1,167 tonnes.

Abengoa, the international company that applies innovative technology solutions for sustainability in the energy and environment sectors, has been awarded by the Oman Electricity Transmission Company (OTEC) the construction of two new electric substations and the associated transmission lines in Northeast Oman.

Abengoa will be responsible for the construction, supply, assembly, and commissioning of two new substations 132/33kV, one located in Samad and the other in Sinaw. The construction project is expected to last for two years. Subcontracting of local businesses for specific tasks will generate local employment in the area throughout the construction period.

Since 2012, Abengoa is present in Oman, where it is currently developing the substation Al Dreez for OETC as well.

With this new project, Abengoa consolidates its position in the Middle Eastern market, keeping its leadership in the electric transmission industry with more than 26,000 km and almost 300 substations around the world in the past 11 years.
