EV microgrids are systems that can charge electric vehicles (EVs) during peak times, reducing grid demand and electricity prices. According to INL researcher Anudeep Medam, who heads the lab's Fast Charging Station Microgrids project, "The microgrid is able to meet the electric vehicle's load demand on its own, reducing the overall cost".
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.
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.

Controller costs per megawatt range from $3,500/MW to nearly $600,000/MW, excluding outliers, with a mean of $85,000/MW.
