Contract Secured For 200MW/800MWh Energy Storage Project In Idaho

Here at CleanTechnica, we have had the privilege to write about recent large energy storage system projects. These projects are exciting news, because in some cases they are paired with clean, renewable electricity such as solar power and wind power. Excess electricity from the clean, renewable sources can be stored for use when there is no sunlight or wind. Some energy storage projects are not paired with renewables; they still help fill in gaps in local grid management.

Battery systems can be cheaper to install than building a new peaker plant and they don’t burn natural gas, which has a cost. They also don’t generate direct emissions that contribute to climate change or harm human health like combusting natural gas does. Typically, a very large battery system can be installed faster than building a new peaker plant. For a little background, Idaho Power has a goal to generate 100% clean energy by 2045. Big battery systems can be used to support the achievement of that goal.

Prevalon Energy just announced the company has secured a contract for a huge energy storage project in Idaho. Prevalon’s Head of Marketing & Communications, Rob Garay, answered some questions about the project for us.

What is the advanced Prevalon HD 511 system and its battery chemistry? 

The Prevalon HD 511 system is an advanced technology designed to enhance performance and efficiency in various applications. It features a robust and reliable design, making it suitable for demanding environments. The system is equipped with a high-capacity battery that ensures long-lasting operation and minimal downtime.

Regarding its battery chemistry, the Prevalon HD 511 system utilizes lithium-ion (Li-ion) batteries. These batteries are known for their high energy density, long cycle life, and excellent performance in a wide range of temperatures. Lithium-ion batteries are also lightweight and have a low self-discharge rate, making them an ideal choice for the Prevalon HD 511 system.

What is the system’s capacity in MW and MWh?

200MW/800MWh.

Will it get its electricity from solar and wind power?

This is stand-alone.

What is the project cost?

We don’t publicly disclose specific cost details.

When will it be operational?

2026.

What is the energy storage system’s expected lifespan?

The expected lifespan of the Prevalon HD511 energy storage system is 20 years.
