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.

How much does a microgrid cost?

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.

Is a microgrid more expensive than a small solar array?

True, larger microgrids will likely be more expensive than smaller microgrids — but in gross terms, not necessarily on a per kilowatt basis. In fact, generation for a very small microgrid tends to cost more per kilowatt than a comparable larger version. For example, a 50-kW solar array is more expensive per kilowatt than 1-MW solar array.

How much does a grid connection cost?

The complexity of grid connection requirements varies significantly based on location and local regulations, with costs ranging from €50,000 to €200,000 per MW of capacity. System integration expenses cover the sophisticated control systems, energy management software, and monitoring equipment essential for optimal battery performance.

How many levels of microgrid sophistication are there?

S&C has identified six different levels of microgrid sophistication, stepping up from the simplest which has only a back-up generator to the most advanced microgrid with multiple forms of generation, energy storage, sophisticated controller capabilities and even the ability to coordinate multiple microgrids. (See chart.)

Should a microgrid be built all at once?

Microgrids don’t have to be built all at once, but can be expanded and improved in phases, with additional sophistication and capabilities layered in over time. By taking this approach, customers can invest gradually, gaining confidence as the microgrid proves its business case.
