A new white paper from Go Electric explores how microgrids can help optimize remote generation for both efficiency and fuel savings. The paper presents a case study of the Go Electric GEM/ISM microgrid system. The author models a 1-MW remote site using three 350-MW generators, both with and without the GEM/ISM microgrid system. The author’s goal is to illustrate how the Go Electric microgrid’s time shifting and sustainability functions increase the efficiency of a remote site’s generation.

Remote sites typically operate with power generated by diesel-fueled internal combustion engine (ICE) generators. Because of the nature of these sites, planners must install a generator sized to handle the maximum expected load, even though this may provide significantly more power than the base load requirements. But, the paper says, “maximizing the efficiency of electrical energy generation can be a significant fuel savings opportunity.”
In the case study, Go Electric explains the two control simulations that it conducted. “The first control simulation considers the three generators as a tied unit where the required generation is split evenly between all three generators.” For the second control simulation, the company added the Go Electric microgrid to the mix. The author illustrates the results of each control simulation with a chart comparing the fuel burn versus the load.
“ICE conversion efficiency gains, load and time shifting using power electronics and storage are techniques that can enhance efficiency and reduce fuel consumption while maintaining site stability.” — Go Electric, “Generator Efficiency Optimization at Remote Sites”
As part of the case study, and to validate the fuel savings potential of the GEM/ISM system, Go Electric ran simulations on seven different load profiles. The results of these simulations are compared in several charts. The author also discusses how the GEM/ISM system can integrate renewable energy sources into a remote site’s generation mix.
The paper concludes that the “Go Electric microgrid system improves energy efficiency 27% and conserves up to 396,000 liters of diesel fuel annually.”
