AES Opens Solar Power Plant In Hawaii

Author: Source: Datetime: 2019-01-21 13:39:46
It is reported that US energy storage company AES has opened a power plant in Kauai, Hawaii, consisting of solar power generation facilities and battery energy storage systems. This type of power plant can generate cheap clean energy, which is critical for the decarbonization of Hawaii's island grids, as many island solar power plants generate excess electricity at noon, but their electricity still depends on adoption at night. Peaking power plant for fossil fuels.

In the two years since AES announced plans to deploy the project, the price of solar power and battery costs has continued to decrease.

The Kauai Utilities Cooperative is completing the commissioning of the Lawa'i Solar + Energy Storage Project, which consists of a 28MW installed solar power generator solar power system and a 100MWh lithium-ion battery energy storage system.

Andrés Gluski, president and CEO of AES, said, "This market is growing at an alarming rate. I think there will be more fossil fuel power plants being replaced."

The project will be operated by the Kauai Utilities Cooperative (KIUC), which is 11 cents per kWh under the power purchase agreement. Most of the power plants in Hawaii's islands use oil to generate electricity, and the project can save considerable costs after it is opened for operation.

 The Lawa'i Solar + Energy Storage Project can deliver 20 MW of power output in less than 5 hours. By storing energy at 100 MWh, the battery energy storage system can operate like a base-loaded power station, providing sufficient power at night until the solar power generation facility is operating efficiently. AES expects to reduce 3.7 million gallons of diesel fuel per year after the project is operational.

Another feature of the project is that if the power outage causes the entire grid to collapse, the project can be blacked out. Compared to independent solar farms, battery energy storage systems can provide more configurations. Therefore, testing all the different features is an interesting process.
