Navigant research defines a microgrid as "an integrated energy system network consisting of distributed energy resources (DER) and multiple electrical loads and/or meters operating as a single, autonomous grid either in parallel to or 'islanded' from the existing utility power grid." While remote microgrids number in the thousands, many are still powered by diesel generation. However, an increasing number of remote microgrids showcase smart and much cleaner combustion technologies capable of reducing diesel consumption by as much as one-third, even without any renewable generation, according to Navigant Research.

In fact, Navigant predicts the total worldwide capacity of remote microgrids will grow from 286 MW in 2013 to nearly 980 MW in 2020. Under a more aggressive scenario, total capacity will reach 1,071 MW in 2020, according to the research.

"Operating in isolation from the wider power grid, remote microgrids are multiplying thanks to a combination of factors, including high costs for existing energy services in many parts of the world and declining costs for solar photovoltaics and other renewable distributed energy generation technologies," said Peter Asmus, principal research analyst, Navigant.  "…while the majority of remote microgrids are being deployed in the developing world, activity is also increasing in Europe and North America."

In many cases, the most advanced creative controls technology approaches for microgrids are being pioneered with off-grid distribution networks. Other technology claims the ability to achieve 100 percent renewable penetration within remote microgrids, according to Navigant.
