Good Energies, Google and Marubeni Investing in Offshore Wind Backbone

Energy investor Good Energies, Google and Marubeni Corporation are investing in the Atlantic Wind Connection (AWC) backbone transmission project. The AWC project is led by independent transmission company Trans-Elect. The 350-mile (563-km) long transmission backbone will provide approximately 6,000 MW of offshore wind capacity, enough power to serve 1.9 million households, when fully complete.

Good Energies, an experienced investor in the development of renewable energy projects across North America, Europe and Asia, and Google are each investing 37.5% of the development capital in the early stage of the project.

The AWC backbone will be built around offshore power hubs that will collect the power from multiple offshore wind farms and deliver it via sub-sea cables to the strongest, highest-capacity parts of the land-based transmission system. By putting strong, secure transmission in place, the project removes a major barrier to scaling up offshore wind, an industry that despite its potential, only had its first federal lease signed last week and still has no operating projects in the US, Google noted.

The Mid-Atlantic region offers more than 60,000 MW of offshore wind potential in relatively shallow waters that extend miles out to sea. These shallow waters make it easier to install turbines 10-15 miles offshore, meaning wind projects can take advantage of stronger winds and are virtually out-of-sight from land. With few other renewable energy options ideally suited for the Atlantic coast, the AWC backbone helps states meet their renewable energy goals and standards (PDF) by enabling a local offshore wind industry to deploy thousands of megawatts of clean, cost-effective wind energy.

The AWC backbone is critical to more rapidly scaling up offshore wind because without it, offshore wind developers would be forced to build individual radial transmission lines from each offshore wind project to the shore, requiring additional time consuming permitting and environmental studies and making balancing the grid more difficult. The AWC project relieves grid congestion in one of two National Interest Electric Transmission Corridors which were deemed to have significant network congestion and need speedy creation of transmission capacity.

Markian Melnyk developed the AWC concept while researching “Offshore Power”, his book on offshore renewable energy. Melnyk was first joined by H.D. Kenneth Epp and Mohamed El- Gasseir, industry leaders in the systematic integration of high-voltage direct current transmission at DC Interconnect; Eli Farrah, an expert in transmission regulation at Dewey & LeBouef; and then Marty Walicki, Paul McCoy and Robert Mitchell, experienced transmission system owners and developers at Trans-Elect. These principals have formed Atlantic Grid Development, LLC, the project’s developer. Paul McCoy is CEO of AGD and Dewey & LeBouef is counsel to the project.

In every city and state people complain about the towers for powerlines but people are allowing the pristine reaches of ocean to be defaced by high turbine towers because they are out of sight. They are hazzard to ships and aircraft and deface many more square miles of area than strip mines ever could and they will not be restored to a semi natural state in the near future as are strip mines.

Requirements for combined heat, cooling and power units to be installed in every building, also including homes, that has natural gas service will eliminate the need for all the benefits of renewable fuels and energy far faster and at lower monetary cost and much less visual cost. ..HG..


HG: A few thousand large offshore wind turbines would produce sustainable power and be a lot less damaging than the Alberta Tar Sands and Deep Sea oil operations. A few odd bird may be killed every year but wind turbines equipped with special automated noise generators can reduce that to a meaningless level.

Ultra high efficiency domestic e-Heat Pumps can supply all the Heat and Cooling required using wind generated clean power.

Future PHEVs and BEVs could also use clean e-power produced with offshore wind turbines.

Large Offshore wind turbines have a much higher production factor, up to 50% in good locations.

Wind and Solar will supply a major part of future power mix.


Frankly, because I am concerned with aesthetics and cost of maintenance - I might rather have one thorium reactor tucked away behind some trees than 300 monster turbines breaking up the ocean floor.

Some wind energy is great. Solar even better as it gets more efficient. But I agree with Henry that a national goal to install CHP systems in small business and residential housing - will be a lot better in the long run.

Distributed energy IS the energy of the future. It depoliticizes the energy monopolies. It eliminates dangerous, expensive and vulnerable transmission wires. Limits the new capacity necessary. And it makes for a far more secure neighborhood and nation by de-centralizing energy generation.

These guys are making a good start:


If the world goes nuclear, something like one large nuclear power plant per one million people would be required. Something like 6000 new reactors would be needed worldwide or 600+ new one in USA and 1300 for China etc.

Many more would object to all those new reactors. The price of radiation ore/materials would multiply. Canada's economy would get another huge boost.

A power source mix with Nuclear, Solar, Wind, Wave, Geothermal, Hydro and a limited number of NG or Synthetic Gas Power plants may be more likely. Each source could supply 10% to 20% of the requirements.


Agree with you on the need for a broad mix Harvey.

In every city and state people have allowed towers for powerlines but people are complaining high turbine towers will deface the pristine ocean views even though the turbines are out of sight.


People objected to invisible slow turning under water turbines to generate sustainable energy from water current in large rivers.

Water molecules must be protected???


Maybe they're worrying about the fish getting dizzy as they watch the turbines spin? lol
