What is HVDC transmission?

High-voltage direct current (HVDC) energy transmission is a time-tested technology that transmits power over long distances more efficiently than alternating current (AC) transmission. In addition, 高压直流输电不会产生与交流输电相关的有争议的电磁场.

What is the project route?

项目路线经过精心设计,占地面积最小, using waterways and existing rights of way to remain out of sight and avoid environmentally sensitive areas such as the PCB cleanup site in the upper Hudson River. The project will run from the U.S.-Canadian border, south through Lake Champlain, along and under the Hudson River, 最终到达皇后区阿斯托里亚的一个换流站.

See maps of the route.

How will this project affect the environment?

因为固态电缆的直径只有5英寸, 可以沿着现有的路权在水下和地下运行它们, 尽量减少对环境的干扰,并保留自然景观. 天博APP非常注意避开环境敏感的地点, 比如哈德逊河的多氯联苯浓度.

How will the cable be installed?

The cable will be installed using low-impact water jet technology that minimally impacts the environment. 请查看如何安装电缆的演示视频:

 

这个项目会在纽约使用架空输电吗?

No. 该电缆将铺设在现有的水道中或埋在地下. 将不会有新的架空传输与该项目有关.

如果电线被切断或损坏,水会带电吗?

If the cable is damaged, HVDC protection reduces the current and voltage to zero in a fraction of a second so there is no possibility of damage to persons, fish or any nearby infrastructure.

电缆一旦下水,将采取什么预防措施来保护它? Can anchors from boats snag it?

防止锚或钓鱼设备损坏缆绳, 这条线位于水道底部以下, 要么被淹没在河床/湖底,要么被屏障覆盖以防止被钩住. 在极不可能的情况下电缆被卡住了, the sheer weight of the cable will inform the vessel that they’ve attached to a major subsurface object. The cable itself incorporates fiber optic thermal and communication protection features that would detect any snag, as well as fault protection equipment at both converter stations to clear any fault nearly instantaneously. These safety features will shut down operations immediately should the cable become damaged in order to protect both life and equipment.

Who is financing this project?

The project will be 100% privately financed. TDI的主要发起人和股权提供者是黑石集团(Blackstone Group). The construction debt financing will come from a consortium of commercial banks and other private debt providers.

What if there are overruns? Will those be passed through to rate payers?

作为一个私人项目,任何成本超支都将由项目的私人业主承担. 纳税人不会受到建设成本超支的影响.

Where is this new power coming from?

TDI designed this project to meet the growing demands of the New York marketplace by bringing new sources of clean, affordable, renewable energy to consumers. 这种能源的来源将是可天博app发电机.

Where is the power going?

电力将被输送到一个将在皇后区阿斯托里亚建造的换流站, New York, 并将接入联合爱迪生电网.

Does the government approve this project? What approvals are needed?

该项目已获得联邦和州的所有必要许可, and we will work with applicable agencies on any permit modifications required to protect the environment. More information on permitting is available here.

这个项目会影响哈德逊河的PCB清理吗?

No. To avoid installing the HVDC cables within areas associated with the Hudson River PCB Dredging Project, 高压直流电缆路线将在尚普兰运河前退出,并遵循街道和铁路的通行权. 线路将埋在整个地区,以避免架空输电对视觉的影响.

Has this type of project been done before? Is it safe to bury cables underwater?

埋地高压直流电缆(HVDC)已经在世界范围内使用了近80年. 高压直流输电线路最早的一些商业用途可以追溯到20世纪50年代初, and many are still in service today. These include projects such as the Neptune project which safely connects New Jersey and Long Island via an HVDC cable that runs right through New York Harbor. HVDC cables are installed to:

  • 尽量减少对环境的影响,保护纽约的风景
  • 避免架空输电工程经常造成的视觉影响
  • 最大限度地减少传统架空输电线路的电能损耗
这个项目需要什么样的维护?

The converter stations will have periodic maintenance performed on transformers and other electrical equipment as specified by the manufacturer. 对电缆进行连续监测, unless damage is detected, they are virtually maintenance-free.

Is this a safe project?

This project is extremely safe, utilizing solid-state cables that are made from well insulated nonflammable materials that do not contain liquids or gels that could leak. The HVDC converter stations are also solid state with no flammable fuel—unlike thermal generation stations. To minimize the possibility of damage, the HVDC converter stations incorporate electrical protection systems that identify and isolate faults in a fraction of a second.

Will the project affect the commercial and recreational use of both the Hudson River or other waterways?

No. 这些水道的当前和未来使用将不受影响.

线路上需要做哪些维护工作?

对电缆进行连续监测, unless damage is detected, they are virtually maintenance free. The converter stations will have periodic maintenance performed on transformers and other electrical equipment as specified by the manufacturer.

Is there any testing that will need to be done in waterways to make sure the lines can be placed in them?

在铺设电缆的水道上已经进行了各种测试. These include a side scan sonar analysis and bottom sampling of the riverbeds and lakes where the project will be located.

What voltage level will the project operate at?

该项目将在300-320千伏之间运行,具体取决于所选择的技术.

2013年4月18日,PSC对你的项目做出了什么重大决定?

The New York Public Service Commission (PSC) issued an order Granting Certificate of Environmental Compatibility and Public Need (permit). The commission found that the project had significant environmental benefits; provided needed transmission supply into a congested NYC load pocket; provided fuel diversity; connected renewable, stable-cost hydro resources into NYC; and strengthened the interconnection between the Quebec and New York grids. 在纽约州建造这个项目需要许可证.

How will the CHPE project connect with Quebec?

The CHPE project will connect to the Quebec transmission system by running matching HVDC cable past the New York–Canadian border and splicing it onto existing cable within the Quebec transmission system. On the Canadian side, 该电缆预计将运行到蒙特利尔市附近的Hertel HVAC变电所. HydroQuebec will be responsible for the connection and infrastructure on the Canadian side of the border.

Response of Champlain Hudson Power Express to Questions Raised by Hudson River Drinking Water Intermunicipal Council

The Hudson River Drinking Water Intermunicipal Council (“Hudson 7”) requested additional information on the Project. 下面的文件是对哈德逊7号提出的问题和天博APP的回答的总结.

TDI Q&A on Hudson River Water Intakes

How much will this project cost?

该项目完全由私人资助,总成本约为60亿美元.

天博APP社区的建设需要多长时间?

阿斯托里亚-雷尼电缆获得批准,将于2024年5月开工建设, 该项目预计将于2025年底完工. 天博APP将在整个施工过程中继续向社区通报情况.

How would this project improve my community?

CHPE will deliver 20 percent of remaining generation needed to meet New York State’s 2030 renewable energy targets. 此外,热电联产所减少的碳排放量将相当于 纽约市街道上的汽车减少了约44%. The availability of renewable hydroelectric power eliminates the need for local fossil power generation in the Astoria area reducing local air pollution. The nature of hydroelectric power allows energy to be held in reserve via dams and re-leased as needed, 提供有弹性、可靠的天博app下载、可再生和负担得起的能源. CHPE将迅速帮助纽约开始向可天博app发电的未来迈进.

Will streets be closed during construction?

We are still evaluating existing field conditions and potential road or lane closures needed for construction. We will work with the DOT and municipalities to develop proper traffic control plans and communicate any temporary roadway restrictions with the community.

在施工期间,我可以完全使用我的房产吗?

Ingress and egress to homes and businesses will be maintained during construction; although that may mean it is provided through a temporary entrance as we access certain areas.

How will this impact my property?

建设将主要在现有的路权上进行. 如果天博APP需要额外的地役权, 项目团队将在施工前与您联系协调.

工程完成后,如何恢复路权和我的财产?

施工结束后,任何受影响的财产将恢复到原来的状态. Some locations along the route may see improvements to crosswalks and pavement to improve accessibility.

如果我在施工过程中需要额外的信息或有问题/顾虑,我该打电话给谁?
