Atlantic Wind files to build offshore power line
- Atlantic Wind Connection plans to file with federal energy regulators its proposal to build a giant power transmission system in the Atlantic Ocean along the U.S. Mid-Atlantic coast to enable the region's offshore wind potential, a spokesman for the project said in an email.
Announced in October, the project will stretch from New Jersey to Virginia and enable up to 6,000 megawatts of wind power that could be built out of sight from land, enough to serve about 1.9 million homes with carbon free power.
Independent transmission company Trans-Elect, a unit of energy company AES Corp, of Arlington, Virginia, is developing the project expected to cost about $5 billion.
Private equity firm Good Energies, Internet search and technology firm Google Corp and Japanese trading company Marubeni Corp are sponsoring it.
Officials were not immediately available to say when the project might enter service.
The Mid-Atlantic region has more than 60,000 MW of offshore wind potential in the relatively shallow waters of the outer continental shelf, Trans-Elect said.
The project could create thousands of jobs, spur economic growth, help states meet renewable energy and greenhouse gas reduction goals and reduce power congestion costs in the PJM power grid by injecting low priced power into higher priced locations, according to a study by economic consultant The Brattle Group.
In addition, Brattle said the project could provide "substantial cost savings" when compared with the piecemeal development of individual wind farms interconnected via radial high voltage alternating current transmission links to the onshore grid.
Atlantic Wind Connection will use High Voltage Direct Current HVDC technology to create a transmission backbone that could connect several large wind farms to the onshore grid in multiple locations.
And, Trans-Elect said the system could be expanded to accommodate more offshore wind energy as the industry develops further.
In addition to this filing with the U.S. Federal Energy Regulatory Commission FERC, Trans-Elect said it will also need approvals from the U.S. Department of Interior, other federal, state, regional and local regulators and PJM, the region's grid operator.
PJM operates the power grid and energy market serving 51 million people in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

State-sponsored actors 'very likely' looking to attack electricity supply, says intelligence agency
OTTAWA - State-sponsored actors are "very likely" trying to shore up their cyber capabilities to attack Canada's critical infrastructure — such as the electricity supply — to intimidate or to prepare for future online assaults, a new intelligence assessment warns.
"As physical infrastructure and processes continue to be connected to the internet, cyber threat activity has followed, leading to increasing risk to the functioning of machinery and the safety of Canadians," says a new national cyber threat assessment drafted by the Communications Security Establishment.
