In Part 1, we looked at how industrial-scale distributed generating plants (typically hundreds of kilowatts to tens of megawatts), powered by renewable energy, are playing an important role in creating a new generation of more resilient, more sustainable power grids. We also saw that, regardless whether they make power from the sun’s distant rays or a nearby city’s sewage sludge, they’re still subject to the same technical requirements for regulating, conditioning, and distributing their output through the power grid as their larger fossil-fueled counterparts.

Here, we’ll take a closer look at how the equipment used in distributed generation systems must evolve to meet the industry’s changing requirements. While still undergoing some growing pains, distributed generation technologies are technically mature and well-defined enough whereby major utility operators, such as the Sacramento Municipal Utility District (SMUD) and CPS Energy, have developed extensive standards that define
