Top 10: Microgrid Companies

Power grids the world over are currently undergoing major renovations. And while grids have always needed repairs and improvements, it has never before happened at such scale or speed.

One of the main reasons why energy infrastructure is under redevelopment right now is the rise of renewables.

All traditional power grids were designed for the steady, predictable flow of fossil fuels, but they often struggle to cope with the intermittent generation of renewable energy, which often comes in peaks and troughs, surges and droughts.

Speaking with Energy Digital recently, Mateusz Zając, Sustainability Leader at ABB, summarised the issue with grids well.

“Think of the electrical grid as a three-lane motorway,” he says. “A lot of it was built decades ago and it's aged well because it's been well maintained. But in many countries, demand has tripled since it was designed.

“Imagine suddenly having three times as many cars on the motorway. And then imagine some of those cars starting to drive the wrong way – that's what distributed energy resources feeding back into the grid feels like.”

Making piecemeal adjustments to national grids answers this challenge, but another solution has started to demand attention in recent years too: microgrids.

A microgrid is a localised energy system capable of operating either in conjunction with, or completely independently of, the main grid. These systems combine energy sources like solar panels and wind turbines with battery storage and intelligent control software, meaning they can balance supply and demand in real time.

The global microgrid market was valued at almost US$100bn by Grand View Research, which demonstrates just how important these technologies are becoming.

In the near term, falling battery costs, maturing control systems and growing policy support across North America, Europe and Asia are all kicking the sector on to new heights.
