The components will be eligible for 80% of the production tax credit (PTC), sPower said.
Solar dominates sPower’s 13GW portfolio, but it also has two wind projects.
They use 27 units of GE’s 2.3-116 model and 46 of GE’s 1.85-87 turbines respectively.
The developer has not named where Vestas’ turbines will be used, but sPower is set to repower a cluster of six projects in the Altamont Pass in California.
The 49.5MW Sand Hill repowering project will see the 5.8MW Altech I, 1.3MW C.W.E.S., 12.6MW Seawest, 1.2MW Venture Wind I and 1.7MW Venture Wind II, and 1.7MW Viking Energy 83 wind farms repowered with 25 turbines.
Repowering is set to take place before 2020, sPower stated.
