Wind turbines en route to Jeffreys Bay Wind Farm

An important milestone has been reached in the construction of the Jeffreys Bay Wind Farm, one of the largest wind farms in South Africa. On 22 July 2013, transportation of wind turbines from the Port of Ngqura to the wind farm site commenced. It is expected that the wind farm will supply enough renewable, green electricity to power over 114,116 South African homes. This will also reduce carbon emissions by more than 420,000 tonnes each year.

The first shipments of components will be transported from the Port of Ngqura to the site, situated between Jeffreys Bay and Humansdorp. Once on site the components will be offloaded beside the wind turbine foundation. There will be two cranes used to erect the turbines and it is estimated that two wind turbines will be erected each week. Final commissioning of the turbines will take place following connection of the electrical works.

"Our team is committed to making every effort to minimise traffic disruptions during this period," said Mark Pickering, general manager of Jeffreys Bay Wind Farm.

Abnormal loads in transit

Trucks with oversized trailers of varying sizes, of up to 50m in length, began transporting wind turbine components from the Port of Ngqura to Jeffreys Bay Wind Farm during the early morning of Tuesday 22 July. Until 31 January 2014, regular deliveries will be made, Mondays to Fridays, throughout the day. Due to regulations, deliveries will not be made over weekends or on public holidays, or at night. "There may be exceptional circumstances, where prior notification will be given to transport over a weekend," explained Pickering.

Transport schedules were made available from 22 July via the wind farm's website, and adverts will be run in local newspapers to assist commuters in their planning.

All loads will travel to site as single consignments, except through Port Elizabeth where there will be a police escort for the larger components that will travel together to reduce disruption in the city. "Due to the length of the transportation vehicles, we urge other road users not overtake, unless in a passing lane or dual carriageway," added Pickering.

In preparation for the turbine transportation programme, the construction team has already made modifications to the N2 highway to accommodate the large turning radius of the abnormal loads.

Harnessing free, clean energy

Jeffreys Bay Wind Farm will comprise 60 turbines on a site spanning 3700 ha. The site was chosen for its optimal wind conditions and minimal environmental constraints, as well as its close proximity to a 132 kV Eskom grid line.

The project is one of the first wind farms being developed by the South African government's Renewable Energy Independent Power Producer Procurement Programme (REIPP). With demand for electricity continuing to grow in South Africa, the introduction of this clean energy will have far-reaching benefits for the country's power sector, economy and people.

The wind farm is expected to start supplying electricity to the national grid by mid-2014. "Not only will the project be able to provide a significant number of homes with clean, renewable energy by harnessing a free source of energy, it will also save millions of litres of water that would otherwise have been consumed in the production of energy," concluded Pickering.
