Wind Power | Hawaii Wind Farm Recommissioned to Power Water Wells

There are plans to recommission the Lalamilo Wind Farm in Hawaii. The wind farm was a 2.7 MW project that was powered by 120 Jacobs turbines and was decommissioned in 2010 in order to replace the outdated turbines.

To get an idea of what the old wind farm used to look like, we have provided an image of the site. It’s not immediately obvious by looking at the picture below but a number of the turbines had fallen off their towers or were destroyed before the wind farm was decommissioned.

Old Lalamilo Wind Farm

The proposed upgraded wind farm will sit on the old South Kohala site and will consist of five Vestas 660 kW wind turbine generators. This will give the new version of the wind farm a total generating capacity of 3.3 MW.

The power that is to be generated by the wind farm will be used to supply power to eight wells in the Lalamilo-Parker well system. This solution is part of a Department of Water Supply plan.

In all, the wells have a combined capacity of 5 million gallons a day which is used from the Mauna Lani Resort to Kawaihae.

The Lalamilo Wind Co. was awarded the $13 million project by the Department of Water Supply. The benefit to the department is that it will cut the power bill for the wells in half over the next 20 years.

It is expected that the project will be commissioned and start providing electricity by the end of 2015 or early 2016. From there, its lifespan has been estimated to be around 40 years.

There is an EA process that will take 60 to 90 days. The land, which comprises 126 acres, will be leased by the project and this is to be acquired from the state Department of Land and Natural Resources.

There is additional work required to bring the wind farm up to a suitable modern standard with road improvements to made, an updated monitoring and control system plus a new 13-kilvolt overhead electrical transmission line.

The project details are open for public comment until July 23, 2014.
