Energy storage project EPC cost ratio

What are EPC costs?

EPC encompass the remaining costs for a turnkey project. The main cost segments are installation, project management, engineering, shipping, and commissioning. Variations in EPC costs may arise from specific site conditions or project requirements.

What causes EPC cost declines?

EPC cost declines are anticipated from several sources, including improvements in energy density, which could decrease site and electrical installation, and soft costs which may be reduced with project experience. The figures to the right show flow battery cost projections, illustrating the potential range in costs and an example breakdown.

What is the difference between EPC and grid integration?

Grid integration costs will vary based on the interconnection voltage, availability and use of existing infrastructure, and design requirements. EPC encompass the remaining costs for a turnkey project. The main cost segments are installation, project management, engineering, shipping, and commissioning.

What is the lifecycle cost of an ESS?

The lifecycle cost of an ESS are divided into four main categories: Upfront Owners Costs; Turnkey Installation Costs (energy storage system, grid integration equipment, and EPC); Operations and Maintenance Costs; and Decommissioning Costs . The table here further segments costs into subcategories and shows items included in this study.

How long does an energy storage system last?

The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
