Unlocking the Value of BESS: The Role of Renewable Energy Deployment

As the world moves towards a more sustainable energy system, renewable energy deployment is increasing at a rapid pace. This has led to a growing demand for energy storage solutions, particularly battery energy storage systems (BESS), which can help balance out the variability and uncertainty that comes with variable renewable energy (VRE) sources like wind and solar power.

In this article, we explore the changing value of BESS in the context of renewable energy deployment and increased VRE penetration. We discuss how the amount of renewable energy on the grid can influence the services provided by a BESS, as well as the impact of VRE penetration on the net load curve and the ability of BESS to provide peak capacity.

We also examine the relationship between solar PV deployment and the capacity credit of BESS, as well as how increasing levels of PV generation can change the shape of the net load curve and increase the value of BESS in reducing peak demand. Finally, we touch on the role of BESS in deferring transmission and distribution investments and supporting the integration of electric vehicles and other new technologies.

As we move towards a cleaner and more sustainable energy future, the value of BESS will continue to evolve and adapt. Understanding these changes and their implications will be critical for utilities, policymakers, and stakeholders alike. As the International Energy Agency notes, “energy storage is key to unlocking the full potential of renewable energy and supporting a more flexible power system.”
