Frequently Asked Questions About Windy Energy by the Department of Energy
HOST: Have you ever wondered how energy storage, like large-scale batteries, could help make wind energy projects more economical? On this week’s Energy Bite, Julian Lamy, a recent PhD graduate of Carnegie Mellon University, has some answers.
JULIAN: Wind projects generate electricity intermittently depending on when the wind is blowing. In some hours, the project produces 100 % of its max capacity, but in other hours it produces 0 energy. But if the project could store energy, then it could deliver power more consistently throughout the day, for example, 50% of its capacity in each hour. One major advantage of this scenario is that the amount of transmission capacity needed for the project now reduces by 50% since the maximum power produced in each hour decreases. This can save millions of dollars in transmission investment costs for big wind projects.
HOST: So, when is this application of batteries economical?
JULIAN: Current costs for storage, like Aquion Energy’s batteries, are about 3 to 5 times what’s needed to make this application economical. So perhaps this would make sense in the future…but storage is a bit too expensive today.
