Energy storage will help with the adoption of intermittent energy, like solar and wind, by storing excess energy for times when these sources are unavailable. 29. Storage technologies are becoming more efficient and economically viable. One study found that the economic value of energy storage in the U.S. is $228B over a 10 year period. 27.
After energy storage is integrated into the wind farm, one part of the wind power generation is sold to the grid directly, and the other part is purchased and stored with a low price, and then is sold with a high price through the energy storage system.
When the energy storage plant lifetime is of 10 years, and the cost is equal to or less than 300 $/kWh, with the increased efficiencies of both charging and discharging processes, the installed storage capacity and the annual revenue of the wind-storage coupled system increase.
For capacity allocation, the capacity of energy storage equipment determines its ability to effectively stabilize wind power fluctuations. In particular, the battery's life attenuation, caused by cycle aging and calendar aging, can affect its long-term wind power smoothing ability.
All the electricity from the wind farm without energy storage is sold to the grid and users. The annual revenue is 12.78 million US dollars. When integrating the energy storage plant, it stores the wind power when the electricity price is low, and releases it when the price is high.
A wind farm with an energy storage device is considered as a whole to be connected to the grid market. Firstly, the energy storage device stores abandoned wind generation to eliminate curtailment. Secondly, it stores wind generation when the price of electricity is pretty low.
Solar (1,080 GW) accounts for the majority of generation capacity in the queues. Substantial wind (366 GW) capacity is also actively seeking grid connection. The amount of offshore wind capacity in the queues (120 GW) represents four times the Biden Administration’s goal of 30 GW installed by 2030.
