The California site has the largest sizing of PV and battery due to significant value from retail bill savings, demand response, and wholesale markets. The value achieved by the addition of PV and battery is large enough to offset the added cost of the microgrid, and this is the only site to have a positive net present value.
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.
The optimal microgrid system, identified by ESM system optimization under various constraints and using the base-case values for all parameters. The “perfect” PV/battery system has the same constraints as the PV/battery system except that the PV output is a nearly perfect, cloudless pattern for the entire duration of the modeled period.
The probability the BESS stops functioning at a level necessary to support a microgrid that is islanded for less than 2 weeks is very small. The anticipated battery degradation rates for systems is inconsequential over a two-week period and can be ignored.
The control system for the smaller microgrid will likely cost less in real dollars but consume more of the overall project budget than the control system for the larger one. “Your control system may be a little less [costly] in smaller ones, but it’s going to be a much larger portion of the cost than in the larger one.
The battery achieves significant revenue from the frequency regulation market. The breakdown of wholesale revenue is about 60% from frequency regulation, 39% from energy, and less than 1% from spinning reserve. The demand response revenue is reduced compared to the diesel-only microgrid because of the reduced EDGs.
Microgrids: From "Too Expensive" to a Cost-Saving Must-Have
Load shifting: Microgrids equipped with battery storage enable businesses to shift their energy use to take advantage of (TOU) rate arbitrage opportunities, charging batteries during cheaper off-peak hours and drawing on that stored electricity during expensive on-peak hours. These savings from load shifting are magnified in microgrids that ...

The net present cost for the hybrid microgrid is about 35% lower than to the diesel-only microgrid. The cost reduction comes from energy savings, demand charge reduction, and reduced diesel fuel consumption. The EDGs achieve significant demand response revenue, and reducing the two EDGs results in a reduction of demand response revenue for the ...
