Community Microgrids for Empowering the Globe

3

• Next 20 years: world-wide electricity demand expected to increase 60% (per IEA) >80% of incremental growth from just: Latin America, Africa &

Middle East, Chindia

• About 20% of global population (~1.5 B people) lack access to electricity Decades and massive capital investment required to build out the

grid, large-scale generators

• Apparent solution: build distributed, self-sustaining, community microgrids

• Significant Barriers Finance: Source of capital/revenue to fund capex and opex of

microgrids Technical: Conventional technologies do not address needs of

distributed microgrids


Requirements to Build Distributed Microgrids

4

• Local, mini grid / operator • Distributed/ renewable power source, scalable as needed • Suitable energy storage solution to provide firm & dispatcheable

power

QER Recommendations

24

• Expand recognition/support of flow batteries beyond DOE (to other federal departments and agencies)

• Reduce threshold, transaction cost for financing ESS • Proactively qualify flow battery technology for financing • Facilitate connecting microgrid technology suppliers to

cooperatives (“exchange”)
