Turbines are in operation at the Oklahoma wind-solar-storage hybrid facility at the Skeleton Creek

In December, NextEra Energy Resources announced the efficient completion and operation of the wind turbines situated at the Skeleton Creek, a hybrid renewable energy facility that the firm is constructing in Oklahoma, United States. The venture will integrate the built 250 MW of the wind energy power with 250 MW of the solar PV as well as a battery storage system of about 200 MW / 800 MWh (four hour period).

On 19th December, the retail power generation firm had said on Twitter that perhaps the “wind portion… is functioning” as well as that our program’s “solar and the battery power storage modules will start operations as soon as 2023.” During the first three decades of the life of the venture for the wind part of the work, Skeleton Creek is expected to produce US$60 million in landowner payouts as well as US$50 million in the tax collection, with estimates for about US$30 million in the landowner payouts as well as US$65 million in the tax revenue for both the solar and the storage part.

A  PPA (Power Purchase Agreement) was agreed with Western Farmers Electric Cooperative (WFEC) in summer 2019 for the program’s energy generation as well as the Skeleton Creek is going to be the first-ever wind-solar-storage hybrid power venture situated in the Southwest Power Pool (SPP) electric grid and retail market coverage area that covers 14 states in the central United States when finished. Located in 3 Oklahoma counties, such as 90 wind turbines manufactured by the GE firm, the project will follow the design and construction of the state’s initial battery storage project, Rush Springs Storage, by the NextEra Energy Resources in March.

The plant is co-situated with another NextEra wind farm which produces 250MW; although at only 10MW / 20MWh, the Rush Springs battery program is much lower than the Skeleton Creek’s would be (two-hour duration). For both the NextEra Energy Resources as well as Southwest Power Pool leaders, who intend to start new architecture regulations for the energy storage facilities in their coverage area in the year 2021, Rush Springs project acts as a test program for the optimization of the wind energy by making use of batteries and increase of grid stability using the battery storage. These new regulations would provide more guidelines for expanding energy storage centres in the country, stated NextEra Energy Resources. “We have seen how the batteries can support us stabilize the regional energy grid’s traffic, trying to smooth the fluctuations of the renewable resources, including wind.”  In November, Bruce Rew, the Senior Vice president of Operations for the SPP said: “power storage can generate value for utilities as well as other generators, and we are assessing how effectively to get such emerging resources onto the grid.”
