Chpe : How To Solve Difficulties Encountered By Other Proposals
Champlain Hudson Power Express (CHPE) is a project of submarine cable to high voltage
DC (HVDC) linking the Montreal area in Yonkers, near the city of New York. Its commissioning is expected in 2015.
The project, proposed by the Transmission Developers Inc. Canadian society. (TGI), would deliver up to 1,000 megawatts of renewable energy from hydro and wind energy in the electricity market of the American metropolis. The estimated construction cost of the project is estimated at 1.9 billion U.S. dollars for the section located in the State of New York .
The Quebec section of the line would be built and operated by Transanergie, the division responsible for Hydro-Quebec's transmission of electricity in Quebec.Electricity rates in the metropolitan New York and Long Island are among the highest in the U.S. and according to the U.S. Department of Energy the metropolis is the "epicenter" of network congestion transport in the Eastern Interconnection. The situation of congestion in the metropolitan region is complicated by the fact that the region consumes two-thirds of the state energy while production facilities are mainly located in the north and west .
Over the years, several projects have been proposed to increase the supply of power transmission to the metropolitan New York, but have often encountered the hostile reaction from environmental groups and communities near the tracks.
Thus, the construction of a submarine cable DC 328 MW, the Cross Sound Cable was authorized to connect Connecticut to Long Island by Long Island Sound. Its commissioning was delayed a year because of the dispute in Connecticut. Another project, the Neptune Regional Transmission System has been put into service in spring 2007. The 500 kV cable with a length of 105 kilometers (65 miles) connects New Jersey and Long Island and is buried in the Atlantic Ocean. It has a capacity of 660 megawatts .
By cons, a line of 306 km (190 mi) to 400 kV DC between the position of Rock Tavern, a hundred miles north of New York, Marcy naked in the center of the state, has been plagued by disputes. Proposed in 2006 , the proposed New York Regional Interconnect (NYRI) with a capacity of 1200 megawatts, has been abandoned by its developers in early 2009. The route of NYRI has been controversial for two years because of opposition from several groups of citizens about the impact of pylons that have crossed their communities .
The TDI project, whose board is chaired by former Ontario premier David Peterson, whose princpaux donors are investment banking firm Blackstone Group and Consulting Engineering Inc., Quebec RSW. , was announced February 23, 2010.
At launch, the CHPE tries to avoid the difficulties encountered by other proposals such as NYRI, including the towers, 10 storeys high, have crossed the populated areas in the counties of Orange and Sullivan, sparking an opposition organized. The initial project consisted of two lines of TDI, the first from New York, and the second, which would have shifted to Connecticut under Long Island Sound. The total cost of constructing the two lines and converter stations in U.S. territory would amount to 3.8 billion .
According to President and CEO, Donald Jessome, choosing an undersea route avoids "disturbing communities with overhead power lines. The developer says that the cable provides economic and environmental benefits to the state, since the available power line would be from renewable sources. He added that talks are underway with the company Nalcor Energy, which provides hydroelectric power and is considering the construction of wind turbines.
