Microgrid unit cost

What is a microgrid cost model?

The National Renewable Energy Laboratory was commissioned by the U.S. Department of Energy to complete a microgrid cost study and develop a microgrid cost model. The goal of this study 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.

How much does energy storage cost a microgrid?

In commercial and industrial microgrids, energy storage represents 15% and 25% of the total costs per megawatt, respectively. In commercial microgrids, soft costs account for 43%, while in community microgrids they account for 24%.

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.

What does Phase 2 of a microgrid project involve?

In a microgrid project, Phase II uses the results of Phase I to gain an initial indication of the costs that might be driving the cost of development the most. Cost information for 80 microgrids was collected through a survey by directly contacting industry members and microgrid owners and from publicly available information.

Are there costing studies on microgrids?

Althoughthere are some costing studies on microgrids in the existing literature, they are mostly carried out for a single case study, producing results that are highly specific to that case’s grid configuration and therefore of limited application to the planning of future projects.

How much new generation is needed for microgrids?

On average, 64% new generation is called for in the winners of the Stage 1 competition. This is slightly less than the average of 71% new generation for microgrids in the community segment in the NREL cost database.
