Report: High voltage, direct-current transmission systems
Like much of the electricity grid, high-voltage transmission in service today relies on many of the same technologies that existed at their conception over 100 years ago. In the last 20 years, however, transmission technologies have benefited from a new stage of innovation. Today over two-thirds of new large-scale transmission systems planned or under construction…
Texas HVDC line to reach Louisiana and Mississippi
Pattern Energy Group LP says it has reached a milestone in development of its Southern Cross transmission project in an agreement with several Texas utilities and making two applications with the Federal Energy Regulatory Commission. “Pattern is making steady progress on the development of its Southern Cross project, which will let Texas share its abundant…
High voltage dc line planned to cross Iowa
Although wind development is surging in many states, transmission developments lag. The problem is conventional transmission lines. They are hobbled by a lack of capacity. Clean Line Energy Partners have several plans to address the issue. One, the Rock Island Clean Line, is a proposal to construct and operate a roughly 500-mile overhead electrical transmission…
HVDC cable could trim most grid losses
High voltage dc transmission lines are one way to reduce the amount of power lost in transmission grids from the current average of about 8% to an estimated 1 to 2%, according to Wolfgang Dehen, chief executive of Siemens’ energy unit. Traditional lines typically lose 8% of power in transmission, leading to higher costs and…
145 kV double-circuit cable connects wind farm to mainland
ABB, Zurich, Switzerland, will supply, install, and commission 116 km of underground cable and 56 km of submarine cable, to strengthen the existing transmission grid and allow using more wind power from the Rødsand II offshore wind park which will be commissioned late 2010. The 145-kV cable is intended to manage overload and has a…
