The 12 idle turbines that line Oahu’s North Shore probably won’t be back online for at least another year and repairs are expected to cost the Boston-based developer more than $8 million. 

This is according to filings by HECO with the state’s Public Utilities Commission on Friday. 

Meanwhile, First Wind isn’t getting paid by HECO since the wind farm isn’t producing any energy. The company took out a $117 million loan from the U.S. Department of Energy for the project. 

The turbines have been off-line since August following a devastating fire that destroyed the wind farm’s battery storage facility. It was the third fire for the wind farm since going online in early 2011. Two other fires, which were minor in comparison, destroyed a couple of inverters.

On a brighter note, First Wind’s Kawailoa Wind Farm started producing energy for residents earlier this month.
