Hardening the System - Undergrounding - 1 views

trends copper transmission undergrounding

shared by Colin Bennett on 25 Jun 13 - No Cached
  • Though mostly immune to wind-related damage, undergrounding facilities are prone to flooding. Undergrounding also presents significant challenges, namely longer repair time and much higher repair costs; damage to underground facilities from Sandy reinforced that. Investor-owned utilities in North Carolina compared five years of underground and overhead reliability data and found the frequency of outages on underground systems was 50% less than for overhead systems, but the average duration of an underground outage was 58% longer.

  • E.ON Netz is using an aluminium underground cable from Nexans in the expansion of its grid infrastructure for wind energy. In the administrative district of Dithmarschen, Nexans has installed a double circuit 110-kV underground cable system for E.ON – the first of its kind for a German customer – with a total length of around 5.5 km and an order volume of € 4 million. The section that has now been connected up is part of the concept of the federal state government of Schleswig-Holstein to transport wind power electricity inland along the coast in a 20-km wide corridor via underground cables. As part of the energy turnaround, E.ON Netz has embarked upon an infrastructure project that will enable a future feed-in of 9000 MW of electricity from offshore wind farms into the 380-kV transmission grid along the west coast of Schleswig-Holstein.

    The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province in central New South Wales. A gold and copper mine, it is 100% owned by Australia's Newcrest Mining, and is one of three operations owned by the company in the province. The others are Cadia East and Cadia Hill, the largest of the three. "The Ridgeway underground mine cave is located in the mineral-rich Cadia Valley province."Ridgeway is in the process of transitioning from the sub-level cave to a block cave beneath the existing mine. In 2007 the Newcrest board approved development of the Ridgeway Deeps block cave. It will be the first natural caving operation to be developed by Newcrest and will be the deepest block cave in Australia. The company says it is spending A$525m to develop it. The mineral resource at Ridgeway Deeps was re-estimated following a geological reinterpretation which yielded an increased resource of 20 million tons containing 0.5 million ounces of gold, and 0.05 million tons of copper.

  • Using the Siemens technology installed on the platforms, the alternating current power generated by the wind turbines is transformed into direct current for efficient transmission to the mainland. At the associated land-based stations, the electricity generated by the connected wind farms is converted back into the alternating current power required for feeding into the transmission grid.
