Using Battery Aging Data to Prepare BESS for Wholesale Energy
Participation in wholesale energy markets offers a critical source of revenue for battery energy storage systems (BESS). Across transmission organizations in the U.S.,
A large-scale Battery Energy Storage System (BESS) can engage in wholesale energy trading in several ways. The fundamental principle behind these methods is purchasing electricity at low prices and then selling it at higher prices.
The market access for a BESS is typically done through an energy trader or a "virtual power plant," which connects a group of distributed energy resources to provide various ancillary services. It's important to understand that different markets have distinct rules and regulations.
These characteristics include the share of renewables in electricity generation, the availability of storage and transmission options, and the overall flexibility of the system. BESS can also participate in markets for ancillary services such as frequency regulation, peak shaving and black start.
For residential customers, whole-house solar batteries and small-scale BESS units provide self-consumption, outage protection, and participation in emerging virtual power plants (VPPs). These products often include lithium-ion or lithium iron phosphate (LFP) chemistries, integrated inverters, and smart monitoring systems for simple deployment.
