Large-capacity microgrid projects

What type of capacity is leveraged for new microgrid projects?

Existing CHP is among the top three generation technologies in terms of capacity used in new microgrid projects, along with existing capacity in the 'Other' category, which primarily comes from a single, 39.6-MW waste-to-energy project.

What is a microgrid project?

A microgrid project refers to upgrading a facility’s backup generators with networked controls, as defined by the DOE. These projects enable the generators to operate in parallel with the grid, and microgrids have various design and control architectures.

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 a microgrid cost?

Microgrids are complex systems that require specialized skills to operate and maintain. Microgrids include controls and communication systems that contain cybersecurity risks. A 2018 study conducted by the National Renewable Energy Laboratory found that microgrids in the Continental U.S. cost an average of $2 million-$5 million per megawatt.

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%.

Are microgrids sustainable?

Today, however, projects are increasingly leveraging more sustainable resources like solar power and energy storage. Microgrids can run on renewables, natural gas-fueled combustion turbines, or emerging sources such as fuel cells or even small modular nuclear reactors, when they become commercially available.
