The models developed for the Applied Energy study, Hong added, can help interested parties understand where these communities are located how clean energy microgrids could be designed and how much it would cost to reduce outages below a desired threshold. “This is the first detailed, state-level study that’s looked at how clean energy microgrids can minimize outage impacts on vulnerable communities, and how much it would cost,” said Tianzhen Hong, a co-author and senior scientist in the Building Technology & Urban Systems Division at Berkeley Lab. These systems, which primarily rely on solar and batteries, can be built at a cost well below what households typically pay for electricity and can reduce the impact of power outages (by minimizing public safety power shutdown time) by a factor of up to 30. But conventional microgrids with diesel generators are both too expensive and too polluting to be viable at scale.Īn international team led by research scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found that clean energy microgrids offer a better and cheaper solution for protecting California communities from wildfire-related outages, compared to conventional microgrids. By using small-scale, local energy sources and disconnecting from regional grids during emergencies, they can deliver essential services to keep homes and communities safe. Microgrids can build resilience in vulnerable communities. For some 46 million Americans living next to forests – at what scientists call the “wildland-urban interface” (WUI) – the risks of wildfire can be especially acute. In California, wildfires and regional power shutoffs have cost billions and taken lives. Long-duration solutions complement short-duration storage, fulfilling flexibility needs beyond solutions such as batteries – which aim to provide power for storage with fast response and short-term use – and delivering flexible and reliable clean energy for longer periods of time.Newswise - Wildfires have become increasingly frequent due to climate change, with record occurrences in areas not historically prone to them. LDES can be scaled economically to sustain electricity provision for multiple hours, days, or even weeks. In long-duration energy storage (LDES), society has the technology that provides balance and meets a growing need for 8-to-18-hour flexibility to close the full day cycle, providing clean power whenever it’s needed, whether as part of a microgrid or larger scope energy system. With new streams of energy being introduced, it is important to align production and consumption. Use of renewable energy sources will continue to rise and be incorporated into energy systems, including microgrids. Why is LDES an important part of your microgrid? ![]()
