While pairing standby generators — say, a gas turbine — with wind or solar farms is not financially viable in most markets, it can make sense at military installations, according to an analysis in Aol Energy.
“The biggest opportunity to pair standby generators with renewable energy is in small grids,” such as on military bases and islands, the article states. One reason for the exception is the likelihood that locations with small grids are subject to high energy costs.
“Many are forced to use the most expensive fuel in the utility industry — oil. In these cases, investors can justify redundant capital investments to offset their costly fuels,” the article states. Essentially, adding renewable energy production to small grids can lower costs by reducing consumption of high-cost fuels.
