| Criteria | BESS | Utility |
| Timeline to Deployment | Deploy a BESS to meet the DCFC Station’s power needs and leverage distributed energy resources (i.e PV, wind, and etc.) | May take several years to pull a new distribution line to meet the power requirement for the DCFC Station. |
| Cost to Implement | Integrating Behind-the-Meter (BTM) BESS with DCFC can significantly reduce total costs. | Based on the existing infrastructure, costs can vary from expensive to prohibitive. |
| Customer Satisfaction | The BESS can be sized accordingly to meet both power and energy demand of the DCFC to reduce the amount time at the charging station. | Utility maybe only be able to provide a certain amount of power where curtailment may take place often. |
| Distribution Energy Resources | Able to leverage DER (i.e. PV, wind, fuel cell, etc.) for more favorable rate in $/kW and $/kWh as a non-wire alternative. | – |
| Revenue | The BESS can be programmed to take advantage of “value-stacking” to offer more revenue benefits. | – |
| Outage | The BESS can ensure electric vehicles are charged even during utility outages. | – |
