Report Finds Battery Energy Storage Systems Can Serve as Viable Transmission Assets for Upgrades to Existing Power Grids

Storage options must be thoroughly integrated into all aspects of grid planning to successfully advance the use of storage for transmission projects

Feb 24, 2022

A new report from Guidehouse Insights explores the benefits of storage as a transmission asset (SATA) in power grid upgrades and provides an update on regulatory changes that are enabling SATA. It also includes recommendations for project developers, integrators, and policymakers to further develop the market.

Upgrading existing power transmission grids comes with challenges such the extensive time needed to plan and build traditional transmission projects and the short-term mindset among local grid operators. As a result, stakeholders want to integrate SATA in the form of battery energy storage systems (BESSs) to supplement or even replace traditional assets. According to a new report from Guidehouse Insights, BESSs can serve as viable transmission assets for upgrades to existing power grids due to their flexibility, scalability, and portability.

“Energy storage is increasingly viewed as a viable option to traditional transmission and distribution investments and a tool to maximize the efficiency of existing grid systems,” says Roberto Rodriguez Labastida, senior research analyst with Guidehouse Insights. “Utilities are now deploying non-wire alternatives as an alternative to upgrading or building additional poles and wires that have long served as the backbone of the electric power system.”

According to the report, storage options must be thoroughly integrated into all aspects of the grid planning and procurement process. In addition, vendors and project developers should focus on vertically integrated utilities and work closely with their customers to offer tailored solutions. Furthermore, to boost confidence for the industry to pursue this application, regulators should provide clear directives that detail storage’s demonstrated value either as a network asset or as an asset that can be used in place of or to enhance transmission.

The report, Utility-Scale Battery Storage Acting as a Virtual Transmission Asset, highlights the benefits of SATA and explores the landscape of market drivers, policies, and new projects around the world. Forecasts for plug-in EV (PEV) electricity consumption—a driver of SATA—are provided by region. This report also provides an update on regulatory changes that are enabling SATA and recommendations for project developers, integrators, and policymakers to further develop the market for SATA. An executive summary of the report is available for free download on the Guidehouse Insights website.
