New York City Will Get an 80,000-Acre Offshore Wind Farm with a $3 Billion Investment

New York City is set to welcome its own offshore wind farm. The Empire Wind 1 project has secured a $3 billion financing package and is slated to begin operations in 2027, providing power to about half a million residents. So, what’s the catch?

In the energy industry, the levelized cost of energy (LCoE) serves as a crucial metric for assessing the overall cost of electricity production across a power unit’s lifespan. It factors in all expenses, including construction, operation, fuel (if applicable), maintenance, output, financing, and loan interest payments.

LCoE allows for direct cost comparisons across different electricity generation methods. For instance, utility-scale solar and land-based wind projects typically average $20-50/MWh, while natural gas-fired plants range from $45-80/MWh.

As of 2023, the global average LCoE for offshore wind farms was approximately $75/MWh. China spends about $65.7/MWh, the UK slightly less at $50/MWh, while Germany, Denmark, and the Netherlands hover around $84/MWh. In contrast, the United States pays a premium, averaging $89.33/MWh.

New York City’s upcoming clean energy project will exceed these averages.

Challenges and Costs

Equinor, the developer of the Empire Wind 1 project, secured an 80,000-acre lease 15 miles southeast of Long Island. The company has contracted with the New York State Energy Research and Development Authority to deliver electricity at $155/MWh for 25 years—nearly double the national average. This price reflects challenges like the 20-25 year lifespan of offshore turbines, limited by high winds, wave motion, and corrosive saltwater exposure.

Sustainability comes at a cost.

While this arrangement might seem like a win for Equinor executives, its financial benefit for NYC residents—where the wind energy will be directed—is minimal. However, it’s a step in the right direction.

A Game-Changer for New York City’s Renewable Energy

The 80,000-acre turbine-filled section of the Atlantic Ocean, nearly half the size of NYC, has the potential to generate 810 MW at full capacity. That translates to approximately 3.19 TWh annually, covering around 6% of NYC’s total electricity consumption. Notably, Empire Wind 1 will become the first offshore wind project to connect directly to NYC’s electrical grid.

Currently, NYC residents pay Con Edison about $0.31 per kilowatt-hour for electricity. Under ideal conditions, the $155/MWh ($0.15/KWh) price tag for Empire Wind 1’s output could theoretically reduce electricity costs to 30.1 cents per kilowatt-hour. However, it’s unlikely that savings will be directly passed on to customers.

NYC, famously the “city that never sleeps,” consumes around 53 TWh annually—more than any other U.S. city. For comparison, Las Vegas, known for its 24/7 casino lights, uses just 25–30 TWh per year, according to the most recent data from 2015–16.

The Shift from Indian Point to Natural Gas in New York’s Energy Supply

Before being decommissioned in recent years, New York’s Indian Point nuclear plant supplied approximately 25% of the electricity for NYC and Westchester County. To compensate for the loss, natural gas-fired power plants have ramped up production, including the aging Ravenswood Generating Station and the Astoria power plant in Queens. Together, these facilities now provide about 28% of the city’s electricity. However, both plants have drawn criticism for their contributions to pollution and greenhouse gas emissions.

Offshore wind energy will enhance the current grid and reduce CO2 emissions, though it comes at an ecological cost. These wind farms can disrupt marine ecosystems in various ways but may also serve as refuges for sea life, as commercial fishing is often restricted in such areas—potentially leading to issues like over-predation.

The U.S. has been slow to adopt offshore wind technology due to regulatory challenges, high costs, and competition from cheaper energy sources like natural gas. Currently, only three offshore wind farms are operational. However, as infrastructure develops, the LCoE of future projects is expected to decrease over time.

Meanwhile, Equinor’s Empire Wind 1 project is set to create over a thousand union jobs for redeveloping the South Brooklyn Marine Terminal and constructing turbines, with operations slated to begin in 2027.
