How are energy storage systems priced?

They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.

What are the different types of energy storage systems?

The survey methodology breaks down the cost of an energy storage system into the following categories: storage module, balance of system, power conversion system, energy management system, and the engineering, procurement, and construction costs.

What are energy storage technologies?

Energy storage technologies are used at all levels of the power system. They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate.

Will additional storage technologies be added?

Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).

What is the Energy Storage pricing survey (ESPs)?

3. Purpose The annual Energy Storage Pricing Survey (ESPS) is designed to provide a reference system price to market participants, government officials, and financial industry participants for a variety of energy storage technologies at different power and energy ratings.

What are the different segments of an energy storage system?

The following are the definitions of the different segments of an energy storage system starting with the central energy storage component and working outwards. Storage Module (SM): An assembly of energy storage medium components (battery) built into a modular unit to construct the energy storage capacity (kWh) of an energy storage system.
