In a standalone microgrid system, prolonging the life of the equipment is necessary to reduce the cost of its replacement. However, the size and installation costs of the storage systems must be appropriate. Therefore, this paper provides an appropriate weighting to minimize the cost of the microgrid system.
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.
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.
Despite the relative novelty of the microgrid market and the challenges faced when discussing microgrid costs, it is a very useful exercise to collect cost information from the microgrid community and better understand component costs and differences from one project to another. The principal goal in Phase I of the study was to collect data.
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.
For example, if a battery is replaced when it falls to 80% of original capacity and microgrid operation requires a certain battery capacity, the battery must initially be oversized by 25% to maintain the desired capacity at the end of the battery’s life.
