Offshore Wind Farm Town Hall
As part of the next steps for Bermuda's Integrated Resource Plan (IRP), the RA invites the public to a town hall forum to present its up to date findings on the feasibility of an offshore wind farm as an alternative, clean source of energy. This forum is the first part of this public consultation on the proposed offshore wind farm. We will also have additional town hall events at different locations throughout the summer.
We encourage all members of the community to take part in this consultation, as public feedback is essential before any final decisions are made.

What is an offshore wind farm?
An offshore wind farm is a collection of wind turbines installed in bodies of water, typically in coastal areas or out at sea. These wind turbines are specifically designed to harness the power of offshore winds and convert it into electricity. The turbines are mounted on fixed foundations or floating structures, depending on the water depth and other environmental factors. This allows the electricity generated by the wind turbines to be transmitted to land for distribution and consumption.
How do offshore wind farms work?
The wind turbines harness the power of wind to generate electricity. The wind turbines are connected to each other through an underwater electrical network and are linked to an onshore electrical grid via submarine cables. When the wind blows, it spins the turbine blades, which then rotate a generator to produce electricity.
How are offshore wind turbines different from onshore wind turbines?
Offshore wind turbines are generally larger and more powerful than onshore turbines. They are designed to withstand harsh marine conditions, such as strong winds and corrosive saltwater. Offshore turbines are typically installed on fixed foundations or floating structures, whereas onshore turbines are anchored to the ground.
Why would Bermuda consider offshore wind farms?
With Bermuda’s limited land mass of 21 square miles, and many densely populated areas, finding suitable land for onshore wind farms is limited. As offshore wind farm may provide an alternative by utilizing the vast expanses of open water. Offshore wind farms are crucial for transitioning to a low-carbon and sustainable energy system. They contribute to reducing greenhouse gas emissions and dependence on fossil fuels, helping to combat climate change and promote sustainable energy sources.
What are the potential economic benefits of offshore wind farms?
Offshore wind farms can bring several economic benefits to local communities and regions.
- They create job opportunities in various sectors, including construction, operations, and maintenance.
- Offshore wind projects can attract investments and stimulate economic growth.
What environmental benefits can an offshore wind farm have?
Can potentially generate approximately 180GWh of clean electricity per year that will meet approximately 30% of the energy needs of Bermuda.
- The displacement of over 110,000 tons of CO2 emissions per year and improved air quality in Hamilton.
- Contribute to the transition towards clean and renewable energy sources, providing insurance against volatile fossil fuel prices and dampening the impact of potential price shocks.
What are the potential environmental impacts of offshore wind farms?
While offshore wind farms are generally considered environmentally friendly, potential impacts can include:
- Disturbance to marine ecosystems during construction and installation.
- Noise and vibration during operation that may affect marine mammals.
- Potential disruption to migratory bird patterns.
- Alteration of seabed habitats due to the installation of foundations and cables.
We are committed to implementing all the necessary mitigation measures to make the impact acceptable.
How much energy can an offshore wind farm generate?
The energy generation capacity of an offshore wind farm varies depending on the number and size of wind turbines and the wind. Large-scale offshore wind farms can generate hundreds of megawatts (MW) to several gigawatts (GW) of electricity, capable of powering thousands to millions of homes.
How are offshore wind farms connected to the power grid?
Offshore wind farms connect to the electrical grid through submarine cables that transmit the generated electricity to onshore substations. These substations then distribute the power to the wider electricity network for consumption.
What is the lifespan of an offshore wind farm?
The lifespan of an offshorewind farm typically ranges from 20 to 30 years, although it can vary dependingon factors such as maintenance, technological advancements, and the conditionof the turbines and infrastructure.
How does the cost of offshore wind energy compare to other energy sources?
The cost of offshore wind energy has been decreasing in recent years, making it more competitive with other energy sources. While initial investment and installation costs for offshore wind farms can be higher compared to fossil fuel-based sources, the operational and maintenance costs are relatively low, and the fuel (wind) is free. As technology improves and economies of scale are realized, the cost of offshore wind energy continues to decline, making it increasingly cost-effective and comparable to other forms of electricity generation.
Are there any challenges in building offshore wind farms?
Yes, there are challenges associated with offshore wind farms. These can include technical complexities in constructing and maintaining turbines in marine environments, high upfront costs, potential conflicts with other marine activities (e.g., fishing, shipping), and the need for specialized vessels and infrastructure for installation and maintenance.
How does the location of an offshore wind farm impact its performance?
The location of an offshore wind farm greatly affects its performance. Factors such as water depth, wind speed and direction, seabed conditions, and proximity to the electrical grid all play a role. Choosing an optimal location with favorable wind resources and suitable conditions is crucial for maximizing energy generation and overall efficiency.
How does offshore wind integrate with other energy sources in the electricity grid?
Offshore wind can integrate with other energy sources in the electricity grid through proper grid planning and management. Balancing the intermittent nature of wind energy with other forms of generation (e.g., natural gas, solar, hydro) and incorporating energy storage technologies helps ensure a stable and reliable power supply.
