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 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.

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 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.

How did EPRI develop a cost range?

EPRI combined data from EPRI and utility projects with publicly available and paid cost and technology reports to develop initial performance assumptions and cost ranges. EPRI also conducted interviews with other cost analysts to understand underlying assumptions in order to ensure that the data used in this study were consistent.

Are energy storage PCs cheaper than solar PV inverters?

Energy storage PCSs currently have a cost premium compared to solar PV inverters, but they are expected to achieve parity with solar PV inverter costs within five to ten years. The reductions will driven by standardization of products, which enables increased manufacturing volume and system design improvements.
