Low wholesale solar battery prices for on-grid and off-grid energy storage. Sealed maintenance-free batteries using gel electrolyte. Ideal for normal to high-temperature environments. Very popular for solar panel system energy storage due to their longevity and lack of fumes due to their sealed container.
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.
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.
Or as S&C Electric’s David Chiesa puts it: “If you’ve seen one microgrid …you’ve seen one microgrid.” So there is no quick and simple price to give a prospective customer. Sources we’ve interviewed cite project proposals as low as $250,000 to as high as $100 million. Generation typically accounts for most of the cost.
Another use case for battery storage on microgrids is aggregating BESS as a virtual power plant (VPP) to correct imbalances in the utility grid. At the grid level, when the supply of power from renewables temporarily drops, utilities need to respond quickly to maintain equilibrium between supply and demand and stabilize the grid frequency.
Lithium-ion (Li-ion) batteries are the most highly developed option in size, performance, and cost. A broad ecosystem of manufacturers, system integrators, and complete system providers supports Li-ion technology. However, the vendors best equipped to bring value to microgrids bring the right components to each project.
The hybrid microgrid consists of networked diesel generators, PV panels, and battery storage. To calculate the expected performance of the backup system for a given outage, we first determine the initial probabilities of being in each system state, which is dependent on the number of working generators and the battery initial state of charge (SOC).

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 ...

EDF Renewables begins its analysis of resilience benefits by looking at how a microgrid''s generation and battery systems can save money when connected to the grid, a factor that will change depending on geography and a utility''s tariff, said Michael Robinson, the company''s associate director for microgrids.
According to NREL, community microgrids have the lowest mean cost, at $2.1 million/MW of DERs installed. The utility and campus markets have mean costs of $2.6 million/MW and $3.3 million/MW, respectively and the commercial market has the highest average cost, at $4 million/MW.

What does a microgrid cost? It''s complicated. Experts from ABB, Hitachi, S&C Electric and Siemens explain what customers should consider when pricing microgrids.
A microgrid must produce cost optimization, resilience, and decarbonization. These results justify the cost of a microgrid. Deployments that achieve all three also lead to a much faster ROI. Two examples of use cases illustrate the potential benefits of energy storage for microgrid owners and utility grid operators.
A 2018 study by the National Renewable Energy Laboratory found that microgrids for commercial and industrial customers in the US cost about $4 million/MW, followed by campus/institution microgrids at $3.3 million/MW, utility microgrids at $2.5 million/MW and community microgrids at $2.1 million/MW, according to Peter Asmus, research director at ...
