Foundation of a wind turbine

GES, an integral supplier of engineering, construction and maintenance for renewable energy projects (wind, solar and hydroelectric) will build the Valdejalón wind portfolio consisting of 5 wind farms in Aragón, Spain. Once completed, the wind farms will have a total installed capacity of 231 MW. Construction is expected to be finalized in 2020 second quarter.

The project is divided into two phases: Valdejalón East which includes the wind farms El Cabezo (49 MW) and Portillo II Phase I (45.6 MW) and Phase II (38 MW), and Valdejalón West composed of Virgen de Rodanas I (49.4 MW) and Virgen de Rodanas II (49.4 MW).

The Valdejalón portfolio is fully owned by the Danish fund manager Copenhagen Infrastructure Partners P/S (CIP) through its fund Copenhagen Infrastructure III K/S (CI-III). CIP is a fund management company focused on energy infrastructure including offshore wind, onshore wind, solar PV, biomass and energy-from-waste, transmission and distribution, and other energy assets like reserve capacity and storage. The company operates in Europe, North America and Southeast Asia.

GES is responsible for the engineering, procurement and construction of the project. The company is already working in the detail engineering, and will be in charge of the complete BOP (Balance of Plant), both the civil work, with more than 60 km of roads and 61 foundations and platforms for the 85 m wind turbines to be installed in the park; and the electrical work, including the underground medium voltage network with more than 55 km of trenches and the 132 kV evacuation line of almost another 50 km, which will connect the two new substations to an existing interconnection substation.

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.

The Secretary of Energy and Chairman of the Board of the CFE, Mexico’s Federal Electricity Commission, Pedro Joaquín Coldwell, and its Chief Executive, Enrique Ochoa Reza, have announced the start of the tender processes for 24 electric and natural gas infrastructure projects with a total estimated investment of US$9.836bn. These involve eight natural gas pipeline projects; four power plants; three transmission line and substation projects; and nine power distribution projects. These projects will add 2,385 km to the gas pipeline network, 1,442 MW to the installed capacity of the National Electrical System, 122 km to the transmission grid and 2,962 to the distribution network.

Transparencia Mexicana will accompany the bidding processes of the eight gas pipelines, the geothermal plant and the fifth phase of the losses reduction project. The other projects will have benefit from a social witness appointed by Mexico’s Civil Service Secretariat. And this is despite the costs involved as the CFE is not required to involve this entity in the process.

At the event organised to present these tenders, the CFE’s Chief Executive commented that thanks to the Energy Reform, the Federal Electricity Commission has entered a new phase as the State power utility with the primary objective of offering a better quality and more environmentally-friendly energy service at lower cost. He added that to achieve this goal, it is essential to have a modern energy generation, transmission and distribution infrastructure in addition to sufficient gas pipelines to transmit natural gas.


Dr. Ochoa Reza explained that these gas pipelines, together with the 11 that are already under construction and undergoing the tender process, the CFE in conjunction with PEMEX, coordinated by the Energy Secretariat, will comply with the target established by the National Infrastructure Programme to increase the National Gas Pipelines System by 75% during the term of office of President Enrique Peña Nieto.

The Secretary of Energy, Pedro Joaquín Coldwell added that the new gas pipelines will cover the energy needs of the central, eastern and western regions of the country.
He highlighted that this gas pipeline grid will connect the main industrial and commercial areas of the Republic, thus resulting in a costs reduction. According to the Secretary, this will make businesses more competitive and the country as a whole more attractive for the location of new factories.
The event, that was held in the Auditorium at CFE, was also attended by Emilio Lozoya Austin, CEO of Pemex; César Emiliano Hernández Ochoa, Under-Secretary of Electricity; and David Suárez, Director General of CENAGAS, the National Control Center for National Gas.

Seaway Heavy Lifting (SHL) has signed contracts with DONG Energy for the transportation and installation of three offshore substations in the UK. The offshore substations will support the power transmission of Burbo Bank Extension, Race Bank and Walney Extension offshore wind farms.

For the execution of the projects Seaway Heavy Lifting will utilise both the Stanislav Yudin (2,500 Mt lift capacity) and the Oleg Strashnov (5,000 Mt lift capacity) crane vessels.

These contracts follow on the recent contracts of the substations for Sandbank and Wikinger offshore wind farms, in Germany; and the successful installation of the Westermost Rough offshore substation in 2014 for developer Westermost Rough Ltd. of which DONG Energy owns the majority shares. SHL has now executed or has a backlog of a total of 25 offshore wind farm substations.
