NRG Energy Inc. and Hawaiian Electric Co. Inc. signed power purchase agreements for the 60.6-MW output of two planned solar facilities on Oahu.

The 14.7-MW output of the Mililani II (Lanikuhana) solar plant will be sold at 11.4 cents/kWh, and the output of the Waipio solar facility, at 45.9 MW, will be sold at 10.4 cents/kWh, which is lower than the 13.5 cents/kWh price offered under now-terminated PPAs with SunEdison Inc., the original developer of the solar projects.

The Hawaiian Electric Industries Inc. subsidiary intends to execute an agreement with NRG for the planned 49-­MW Kawailoa solar project, according to a Jan. 31 news release.

NRG Energy acquired these projects in November 2016 from SunEdison after Hawaiian Electric terminated the original PPAs during SunEdison's bankruptcy proceedings.

The companies are awaiting on the approval of the PPAs by Hawaii Public Utilities Commission. Upon completion in 2019, the three projects will generate 109.6 MW.
