Golden Plains battery energy storage system

The battery energy storage system we plan to construct at the Golden Plains Wind Farm in Kossuth County, Iowa, will store up to 75 megawatts of energy, enough to power about 80,000 homes for four hours.

How does battery storage work?

Battery storage systems charge from the grid when energy demand is low or directly from wind or solar projects when excess renewable energy is abundant. They then release this energy as needed when demand increases, such as on hot summer or cold winter days.

How does battery storage affect our future?

The Golden Plains battery storage project is one more way we’ll deliver safe, reliable energy and help keep bills as low as possible. We’ll be able to store more energy from renewable sources, which will help ensure we have enough energy to support growing demand today and in the future.

As the electric grid evolves, we are leading the way with new and innovative solutions for our customers. We work to integrate new technologies and optimize resources like wind and solar alongside traditional generation systems.
