READ MOREHowever, with microgrid-as-a-service (also called energy-as-a-service) offerings, contracts require little or no upfront capital paid by microgrid customers. Instead, customers pay for their microgrid service in a budgeted manner, much as they do if they buy it from a utility, except they have the added benefit of backup power during grid
READ MORE2020. TLDR. This work presents a detailed view on how the current policy scenario for the electricity sector in Brazil is prepared to absorb the concept of microgrids in both its technical and commercial scope and contributes to policy analysis that serve to leverage the insertion of microgrid in the context of the Brazilian energy sector. Expand.
READ MORE[44] prepared a review of the impacts of government policies on microgrid economics. One of the main objectives of government policies is to help grid owners achieve economic efficiency, such as minimizing capital costs and/or operating costs. A variety of policies can be implemented to achieve this objective.

READ MOREA microgrid is a small-scale power grid that can be operated independently or in combination with the area''s main electrical grid. Any small-scale localized station that has its own power resources, generation and loads and definable boundaries can be qualified as a microgrid. Microgrids can be intended as back-up power or to support the
