FAQ

When will the project be built?

The development process for Atlantic Shores Offshore Wind is already underway, including research and permitting. This phase could potentially extend up to five years. Subject to a positive final investment decision, the wind project could deliver electricity by the mid-2020s.

Will the turbines be visible from the shoreline?
The turbines are expected to be built approximately 10-20 miles from the shoreline. Under certain visibility and weather conditions, it is likely that the turbines could be seen on the horizon. Shoreline views are something that Atlantic Shores is carefully taking into consideration during our current planning process.
How much will it cost to construct the project?

Construction of Atlantic Shores Offshore Wind is privately funded through a joint venture between EDF Renewables North America and Shell New Energies.

How will the wind turbine layout be designed?
  • Wind turbines will be aligned in a uniform grid meaning the same distance between turbine rows, and then the same distance between turbines within those rows. This will help create natural transit corridors for vessels within the layout.
  • Based on existing vessel traffic patterns in the area, we are spacing our wind turbine rows no closer than 1 nautical mile from one another. Wind turbine rows have also been oriented to match the predominant direction of vessel traffic.
  • The number of wind turbines and the distance between individual wind turbines along each row is still under development. Final spacing between turbines in a row will balance many factors and existing ocean uses, including fishing activity, avoidance of sensitive habitats, engineering design standards for turbines, and if the turbines are able to perform at their maximum capacity without interfering each other
How are the sizes (or makes and models) of wind turbines determined? How big is the average turbine?
  • Atlantic Shores is working with the leading global suppliers to determine which turbine will be best suited for our lease area that provides best certainty and performance in delivering energy.
  • Over the last decade (2010-2020), turbine technology has significantly advanced. The distance across turbine blades (rotor diameter) has nearly doubled and turbine heights continue to increase. Turbine technology will continue to become more efficient and economical as global offshore wind demand increases.
  • The choice of wind turbine will be made with careful consideration based on where technology will be in the near future. · A study by the National Renewable Energy Laboratory (NREL) describes present-day turbine technologies have a total height of around 850 ft from mean sea level and a rotor diameter of around 750 ft. Blades extend down to about 75 ft above the water. It is important to note that these measurements numbers vary depending on specific turbine manufacturers and models. More information can be found here.
What kind of Scour protection will be used around the wind turbines?
  • Scour protection may be installed at the base of each foundation to protect it from sediment transport/erosion caused by water currents.
  • There are a range of scour options that Atlantic Shores is currently evaluating:
    • Rocks: up to three layers of rock, with the lower layer(s) consisting of smaller rock and the upper armor layer consisting of larger rock.
    • Rock bags: a rock-filled filter unit enclosed by polyester mesh that is non-corrosive, rot-proof, and weather-resistant with proven 30-year durability.
    • Grout- or sand-filled bags: bags filled with grout or sand and lowered into place by the installation vessel cranes.
    • Concrete mattresses: high-strength concrete blocks cast around a mesh (e.g., ultra-violet stabilized polypropylene rope) that holds the blocks in a flexible covering.
    • Ballast-filled mattresses: a folded mattress filled with ballast material (i.e., a sand/water/bentonite mixture or similar) that is lowered to the seabed and unfolded at the base of the foundation.
    • Frond mattresses: buoyant fronds approximately 3 ft (1 m) high, which are designed to replicate how natural seaweed reduces water velocity locally, are densely built into a mattress, and are deployed either directly onto the seabed or attached to the structure.
  • The need for and selected type of scour protection will be determined by the final design of the foundations, environmental and seabed data collected, and ongoing stakeholder and agency consultations.
How will cables be buried?
  • There are 2 types of cables that will be installed within the Lease Area
    • Inter-array cables which run between wind turbines; and
    • Export cables which run from the project substation to the onshore substation.
  • All cables will have a target burial depth of 6 ft (2m).
  • The need for cable protection (such as rocks) will be avoided whenever possible, however it may still be required in specific areas to support the crossing of existing fiber optic or power cables located on the seabed.
  • All cables will be monitored for burial throughout project operation. To ensure cables remain buried at the surf zone, they will be installed under the beach using a horizontal directional drill (HDD). A typical HDD will put the cable tens of feet under the beach.
Will turbines have lighting?

Wind turbines will be marked and illuminated based on requirements established by the U.S. Coast Guard (USCG) and the Federal Aviation and Administration (FAA). Wind developers are working with mariners and agencies to determine best practices for lighting and marking that meet needs of mariners.

Will fishermen be able to fish within the wind farm

We will not restrict fishing in the Lease Area or around our wind turbines once constructed. It is our intent to coexist with the fishing community. To ensure safety of mariners and Atlantic Shores team, there could be temporary exceptions to this during the construction phase. We will work closely with mariner and fishing communities at the appropriate time if temporary exceptions are necessary.

How will Navigational Safety be prioritized?
  • Navigational safety is a priority for Atlantic Shores. We fully recognize there must be balance and coexistence between the multiple users and uses in our Lease Area and to do so without compromising mariner safety.
  • Atlantic Shores has conducted a detailed Navigational Safety Risk Assessment for the Project Area that evaluates the Project-related effects on all types of vessel navigation.
  • In addition to the USCG and FAA wind turbine marking and lighting requirements, Atlantic Shores will utilize additional technologies within the Project Area, for example:
    • AIS systems on the wind turbines to aid mariners transiting in the area.
    • Weather and sea condition monitoring devices.
    • Expanded communication networks within the wind farm
What happens to the project when it’s time to retire?
  • Atlantic Shores’ joint venture partners - EDF Renewables and Shell - each have a longstanding history operating and providing energy responsibly in the United States.
  • BOEM requires all projects to be removed at the end of their lifespan unless otherwise authorized. Atlantic Shores’ obligation is to post financial security to cover this cost over the time and terms of our Lease.
What about job opportunities?
  • Atlantic Shores is committed to hire locally whenever possible. This a top priority for our company.
  • Atlantic Shores is already employing local fishermen and their facilities for scouting and dock-side vessel support. We are also actively looking to expand these opportunities with local fishermen and businesses. In September 2020, Atlantic Shores distributed a formal Request for Information to identify fishing businesses that had available docks and port real estate that could be shared by Atlantic Shores and support our construction and operations efforts. If you are interested in this opportunity, please reach out to our FLO Captain Kevin Wark.
Will the project affect existing Artificial Reefs?

Our Lease Area and export cable routes are planned to avoid state and federal artificial reefs. These artificial reefs will also be avoided during construction and maintenance of the project. If new artificial reef locations are established, these will also be included in our project design planning.
