Microgrid depreciation period

How much does a microgrid cost?

The analysis shows that controller costs per megawatt range from $6,200/MW to $470,000/MW, excluding outliers, with a mean of $155,000/MW for the microgrids in the database. In total, controller cost data was available for 21 microgrids out of a total of 80 projects in the Phase I Microgrid Cost Study by NREL.

How much does energy storage cost a microgrid?

In commercial and industrial microgrids, energy storage represents 15% and 25% of the total costs per megawatt, respectively. In commercial microgrids, soft costs account for 43%, while in community microgrids they account for 24%.

What percentage of microgrid costs are soft costs?

Soft costs, which include interconnection, financing, engineering, procurement, and construction management, range from 0.4%–1.6% of total microgrid costs, as shown in Figure 24. Figure 25 shows the total percentage of soft costs in relation to total microgrid costs.

What is the DOE's microgrid cost study?

The U.S. Department of Energy’s (DOE’s) microgrid cost study is identifying the costs of components, integration, and installation of U.S. microgrids; project cost improvements; and technical accelerators during the next 5 years and beyond.

Why is it difficult to generalize costs for Microgrid technology?

It is particularly challenging to generalize costs for microgrid technology because every installation has unique design and architecture characteristics that affect the overall cost of the individual microgrid components.

What does Phase 2 of a microgrid project involve?

In a microgrid project, Phase II uses the results of Phase I to gain an initial indication of the costs that might be driving the cost of development the most. Cost information for 80 microgrids was collected through a survey by directly contacting industry members and microgrid owners and from publicly available information.
