Nā Pua Makani Wind Farm

Nā Pua Makani is a wind energy project located in Kahuku that will harness the plentiful wind resources of Oʻahu’s North Shore and convert it into clean, sustainable energy.

Wind Farm Facts

Nā Pua Makani Wind Farm

The Nā Pua Makani Wind Farm project will generate renewable energy and help achieve Hawaiʻi’s clean energy goals. Set to begin operation by May 2020, the project has a nameplate generating capacity of approximately 27.6 megawatts (MW), will provide some jobs for the local community both directly and indirectly and reduce Oʻahu’s dependence on oil. Expected to generate enough electricity to power approximately 7,000 homes annually. Lowers fossil fuel usage and greenhouse gas emissions by reducing CO2 by approximately 50,000 metric tons. This is equivalent to approximately 10,000 passenger vehicles driven for one year.

Frequently Asked Questions

Why are the wind turbines so tall?

The higher you get from the ground, the stronger and more steady the winds are.  A turbine’s capability to produce power increases significantly with height, as does its efficiency.

How much will residents hear the turbines while they’re operating?

In the Kahuku residential area and neighboring schools, the sound level will not exceed 40 decibels, which is comparable to a suburban area at night or a quiet library.  Upon operation, AES Nā Pua Makani will have a North Shore team leader available to hear community concerns about noise and able to evaluate whether additional restrictions during sensitive hours is warranted.

Are there health concerns associated with wind turbines?

Turbines have no adverse effect on human health or environmental health.  A recent report shows that shadow flicker, a moving shadow created by turbine blades between the sun and the observer, is hardly noticeable at 1,000 feet from the turbine.  Since Nā Pua Makani is setback at least 1,648 feet from the Kahuku residential area, shadow flicker is almost entirely contained within the site of the wind farm itself.  Furthermore, computer modeling used to calculate potential shadow flicker indicates zero shadow flicker hours at the schools.

How will AES mitigate impact on our endangered bat population?

Our Habitat Conservation Plan, developed over three years in consultation with the Division of Forestry and Wildlife and the U.S. Fish and Wildlife Service and approved by the Board of Land and Natural Resources in 2018, has three protective components:

1.  Prevention — Our low wind speed curtailment is the most effective known approach to reducing bat fatalities.  In addition, within our first year of  commercial operations and in coordination with wildlife agencies, we plan to pilot a supplemental bat deterrent system running at other wind facilities with promising results.

2.  Monitoring — Our onsite operations staff will be trained to recognize any incidents of harm to bats or other species and they will conduct surveys below the turbines to document any such impact.  Additionally, we will have regular monitoring by trained biologists, the Division of Forestry and Wildlife and the U.S. Fish and Wildlife Service.

3.  Restoration — To benefit the Hawaiian hoary bat, we will invest $4.2 million to monitor wildlife impacts on-site and to provide materials, personnel and support for habitat restoration at the Poamoho Natural Area Reserve.  By preserving habitat outside the wind farm, we avoid attracting bats near the turbines.  We will also support research into the life history and needs of the endangered bat population.
