Severe weather events in the United States have doubled in the last two decades, presenting unprecedented challenges to our power infrastructure. Last year alone, these events cost the US economy a staggering $176.9 billion.
As we brace for a long winter with looming ice storms in Texas and debilitating snowfall in the Midwest, the need for a reliable and resilient power grid has never been more acute.
With that, Rural Electricity Cooperatives (RECs) bear the responsibility to maintain a grid that can withstand times of adverse weather.
Amid these challenging times, the role of distributed generation and microgrids has never been more pertinent.
They are not mere backups. They’re sophisticated systems designed to bolster our energy resources during these weather events, creating the reliability and resilience grid that our rural communities rely on.
Reliability Versus Resilience: What’s the Difference?
Though often thought of interchangeably, reliability and resilience represent distinct aspects of how our power system operates, especially under duress. Understanding the difference is crucial in comprehending how microgrids and distributed generation can fortify our energy infrastructure.
A reliable grid: A power supply that remains consistent and predictable in everyday situations and demands. In a reliable grid, power outages are rare and short-lived, ensuring that daily life and business operations go uninterrupted.
A resilient grid: A power supply that withstands duress and recovers quickly from unexpected disruptions, particularly those due to severe weather events or other emergencies. A resilient grid is designed and managed to anticipate, absorb, adapt to, and rapidly recover from such events.
While reliability focuses on maintaining normalcy, resilience is about bouncing back from the abnormal. In the face of climate change and increasing severe weather events, this distinction becomes crucial. A grid might be reliable under normal conditions but falter during a severe storm or a natural disaster. This is where resilience gains prominence.
Aging Infrastructure and Its Impact on Rural Communities
The United States’ power grid, while a marvel of modern engineering, is showing its age. Its age not only highlights a challenge but underscores a pressing need for alternative solutions like grid-tied microgrids.
The Stark Reality of Our Aging Grid
Our current power infrastructure is alarmingly outdated:
- A huge portion of power plants have surpassed the 30-year mark
- Approximately 70% of transmission lines and transformers are over 25 years old
- Compared to three decades ago, the frequency of power outages has tripled
This aging infrastructure leads to inefficiencies and vulnerabilities that are exacerbated during extreme weather conditions, making the situation even more precarious for rural communities.
While updates to our energy infrastructure are necessary, they’re often time-consuming and costly. That’s where proactive steps to enhance energy independence from the grid come in – via grid-tied microgrids and a move to incorporate distributed generation into your energy supply mix.
The Role of Grid-Tied Microgrids
Microgrids are designed to not only provide a consistent power supply but also ensure continued operation during grid-wide failures. In situations like ice storms or heavy snowfall, microgrids can:
- Operate entirely independently from the main grid using systems like battery storage, ensuring continuity of supply
- Offer critical backup power to main grid systems during peak demands or emergencies with fast-action reciprocating engines for immediately dispatchable power
- Incorporate renewable energy sources like PV Solar to enhance sustainability and reduce reliance on traditional fossil-fueled power sources
Grid-tied microgrids are designed with the worst-case scenarios in mind, which include coincidental peak (CP) events, blackouts, and of course, severe weather conditions. The effectiveness of those designs lies in their customization to address specific regional challenges, create the best energy supply mix, and anticipate supply threats.
