READ MOREMG: A microgrid tariff is a mechanism that can be offered by regulators to monetize more of a microgrid''s benefits, increasing financial benefits to the developer and creating a stronger economic case for the project. Tariffs can also address another existing barrier – the resistance of utilities to adopt microgrids into their ecosystem.
