Built much closer to end-users, if not on-site, and equipped with combined heat and power (CHP) technology, microgrids are typically more efficient than centralized power generation and distribution systems. Often making use of renewable energy resources, they’re also emissions-free, or at least significantly less polluting, than traditional fossil fuel-fired power generation.
More frequent and longer lasting power outages due to more frequent and extreme weather events and aging power infrastructure are also fueling interest and investment in microgrid technology and deployments. Boosting infrastructure spending, in turn, means more jobs and rising personal income.
Furthermore, growth in residential solar PV installations has driven growth and the emergence of power ¨prosumers.¨ That, in turn, is resulting in growing public interest in, and calls on government leaders, to institute industry and market reforms that support power production at the homeowner scale, such as net metering.
Adding to these benefits is microgrids’ flexibility in terms of use. This extends across: primary or quick-start back-up generation, emergency recovery, load shifting, peak shaving and ancillary grid services, such as frequency and voltage regulation.
Though small, highly fragmented and posing numerous challenges to developers, the North American microgrid market is growing fast, Navigant highlights in its ¨Multi-client Microgrid Study.¨
At present, campus/institutional microgrids account for the largest segment of the market. Growth is expected to accelerate in the utility microgrid segment as states continue to enact policy and regulatory reforms in order to meet power infrastructure needs.
Similarly, community microgrids are also growing rapidly in order to enhance grid resiliency in the face of climate change, as well as realize associated social and environmental advantages and benefits.
The microgrid benefits everyone by creating cleaner, more resilient communities. The bulk power system can also benefit from microgrid flexibility.
