Utilities are increasingly using battery energy storage to integrate renewables and provide more flexibility to reinforce grid operations. Large-scale BESS is one technology solution to mitigate the "Duck Curve" resulting from the production profiles of solar plants. This panel session would cover the project implementation experience of two recent BESS plants in the Western US, the PG&E Elkhorn project and Salt River Project's (SRP) Bolster plant. In this session you will learn details about the projects as well as how utilities are configuring BESS plants for flexible and reliable grid operation. The session will also touch upon practical implementation of site testing to ensure BESS functionality and performance matches the expected performance.

Key Takeaways:

• Understand utility drivers for application of transmission-scale BESS plants.

• A look at how utilities are configuring BESS plants rated in the 10's and 100's of MWs.

• Future considerations for BESS plant performance.
