How much does energy storage cost a microgrid?

In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.

What is a microgrid cost model?

The U.S. Department of Energy commissioned the National Renewable Energy Laboratory to complete a microgrid cost study and develop a microgrid cost model. The goal is to elucidate the variables that have the highest impact on costs as well as potential areas for cost reduction. This study consists of two phases.

How much does a microgrid cost per megawatt?

The analysis of total microgrid costs per megawatt shows that the community microgrid market has the lowest mean, at $2.1 million/MW of DERs installed; followed by the utility and campus markets, which have mean costs of $2.6 million/MW and $3.3 million/MW, respectively. Finally, the commercial market has the highest average cost, at $4 million/MW.

How much does a microgrid controller cost?

The analysis shows that controller cost data as a percentage of total microgrid costs are relatively similar among the projects in our database and the NY Prize data despite the wide variety of system sizes, types, and uses. Controller costs per megawatt range from $3,500/MW to nearly $600,000/MW, excluding outliers, with a mean of $85,000/MW.

Where can I find a report on microgrid costs?

This report is available at no cost from the National Renewable Energy Laboratory (NREL) at Giraldez, Julieta, Francisco Flores-Espino, Sara MacAlpine, and Peter Asmus. 2018. Phase I Microgrid Cost Study: Data Collection and Analysis of Microgrid Costs in the United States.

What is a utility microgrid?

For utility microgrids, existing PV projects are in the form of DERs with the highest capacity, followed by new natural gas, diesel generators, and energy storage. Note that this group has only five entries in the database, and one of them integrates an existing, large PV project under a power purchase agreement.
