Microgrids Bring Power Back To Communities As Extreme Weather Intensifies

Renewable-Powered Microgrids Offer Lifeline for Communities Struggling with Power Outages

As the United States continues to grapple with climate change, communities across the country are turning to a cutting-edge solution to bolster their resilience in the face of extreme weather events: renewable-powered microgrids. These self-contained power generation, storage, and distribution systems can operate independently from the main grid, providing critical energy during outages and natural disasters.

In recent years, hurricanes like Helene and Maria have highlighted the need for more robust energy infrastructure. In Hot Springs, North Carolina, a small mountain town of 520 people was able to restore power to critical facilities – including a fire station, gas station, grocery store, and diner – in just five days after Hurricane Helene devastated the area. The town’s all-renewable microgrid, which uses solar panels and battery storage, succeeded as the sole source of electricity for seven straight days until a mobile substation could be brought in to reconnect the town to Duke Energy’s main grid.

Experts say that renewable-powered microgrids like Hot Springs’ can provide a critical lifeline for communities struggling with power outages. “Microgrids are not a silver bullet, but they are a great tool in the toolbox,” says Jason Handley, general manager of Duke Energy’s Distributed Energy Group. “They offer a quick and effective way to ensure energy availability during outages, and can even help reduce carbon emissions and costs.”

Other communities that have benefited from microgrids include Babcock Ranch, a developer-planned town in Florida designed to be eco-friendly, with climate change resilience in mind. The community withstood back-to-back battering from Hurricanes Helene and Milton thanks to its on-site solar farm, extensive stormwater control features, and underground electricity distribution system.

However, microgrids are not without their challenges. They can be expensive, and customers often end up bearing the extra burden in their monthly utility bill. But experts say that the alternative – paying a steeper price for not having resilience solutions – is often more costly in the long run. “If you consider all these externalities,” microgrids are often financially viable, says Dasun Perera, an energy system researcher at Princeton University.

In cost-benefit analyses conducted in California, Chicago, and Puerto Rico, microgrids have proven to be a valuable investment. As the price of solar panels and batteries continues to decline, the benefits of microgrids only become more pronounced. “Microgrids will only become more advantageous as technology improves,” says Perera.

While microgrids may not be right for every community – particularly those with limited access to renewable energy sources or where the cost of diesel generators is low – they offer a vital option for communities looking to improve their resilience in the face of extreme weather events. As the world continues to evolve, it’s clear that energy systems need to keep up. Microgrids are an important part of this effort, providing a reliable and sustainable source of energy for communities across the country.

In addition to microgrids, experts recommend major upgrades such as replacing miles of utility poles, weatherizing substations and power plants, or moving lines underground as long-term fixes. Investing in energy efficiency should also be a priority, reducing strain on the grid and lowering emissions. But when it comes to immediate action, renewable-powered microgrids offer a powerful solution for communities struggling with power outages.

The role of microgrids is becoming increasingly important in the US energy landscape. Whether you’re a community leader looking to improve your resilience or an individual seeking ways to reduce your carbon footprint, microgrids are an option worth exploring, providing a vital lifeline against the threats of climate change.
