6 FAQs about [Impact of uncertainty on microgrids]

Is market restructuring a threat to a microgrid?

Market restructuring, like that proposed in New York's “Reforming the Energy Vision (REV)” effort, will be required to move from a situation where microgrids are viewed as a threat to one in which distributed energy resource services are valued by the utility grid and fairly compensated .

What are the advantages of microgrids?

Microgrids are a flexible solution for a broad diversity of stakeholders. The advantages of microgrids range from resilience to renewable integration. Microgrids are moving from the laboratory to broad community deployment. Microgrids still face significant legal and regulatory uncertainties.

What happens if a microgrid goes down?

Microgrids can provide power to important facilities and communities using their distributed generation assets when the main grid goes down. Because electrical grids are run near critical capacity, a seemingly innocuous problem in a small part of the system can lead to a domino effect that takes down an entire electrical grid .

Are microgrids part of the restructured New York electricity market?

The ecosystem of players in the restructured New York electricity market includes smaller generating companies called Independent Power Producers (IPPs). Microgrids, as such, do not fit neatly into the classes of market participant defined by restructuring, perhaps because they transcend the categories of generation, transmission, and distribution.

Are microgrids a viable business model?

The ownership and business models of microgrids are still evolving. Microgrids are now emerging from lab benches and pilot demonstration sites into commercial markets, driven by technological improvements, falling costs, a proven track record, and growing recognition of their benefits.

Do microgrids qualify as utilities?
