Impact of Extreme Weather on Energy Infrastructure Resilience

Assessing Infrastructure Vulnerability to Extreme Weather

Many renewable energy technologies, such as hydropower, wind, and solar energy, depend on weather conditions to generate power. While these natural elements are essential for energy production, extreme weather events can negatively impact renewable energy plants. Such events can reduce energy output, strain the grid, and even damage renewable energy infrastructure, with the increasing frequency of extreme weather often linked to climate change.

Although the full impact of climate change on renewable infrastructure is not yet fully understood, experts agree that the unpredictable and severe weather patterns associated with climate change pose significant risks to power grids. Here, we explore how extreme weather affects renewable energy infrastructure and discuss strategies to mitigate its negative impact while adapting to climate change.

The Economic Impact of Weather-Related Infrastructure Damage and Lessons Learned

When planning a renewable energy plant, it's crucial to consider the potential impact of extreme weather on infrastructure. Different types of renewable energy technologies are better suited to specific weather conditions, and some can withstand extreme conditions better than others.

Safety Requirements for Human Maintenance

Most renewable energy technologies require human intervention to maintain optimal performance. Renewable energy engineers are responsible for maintaining infrastructure, especially when extreme weather conditions cause damage. However, many renewable energy arrays are located in regions prone to extreme weather, such as coastal areas. When conditions are poor, it may be impossible for engineers to access and maintain these arrays.

Prolonged poor weather conditions that prevent timely maintenance can lead to infrastructure deterioration, sometimes beyond repair. This deterioration can reduce the productivity of renewable plants, leading to downtime and costly repairs that impact revenue. Therefore, the viability and productivity of renewable arrays in extreme weather-prone areas should be carefully considered before construction.

The Impact of Overheating on Solar Panels

While solar panels rely on sunlight to generate power, excessive heat can actually reduce their productivity. Current solar panels can only function optimally up to 23 degrees Celsius. During extreme heatwaves or droughts, solar panels can overheat, leading to reduced power generation or even permanent damage.

To combat the effects of overheating, more resilient solar panels capable of withstanding higher temperatures need to be developed. This would minimise the economic impact of overheating on solar plants.

The Impact of Extreme Heat on Transmission Lines

Extreme heat can also affect the delivery of renewable power from generation plants, particularly solar farms. Overhead transmission lines may experience reduced capacity during periods of extreme heat. This issue can be exacerbated by increased demand for electricity as surrounding infrastructure relies more heavily on cooling systems due to higher temperatures.

Strategies and Policy Recommendations for Building Resilience in Energy Systems

While renewable energy generators cannot control extreme weather events, they can plan for them. Here are some strategies to mitigate the effects of extreme weather and build resilience in renewable power plants through grid-hardening techniques.

Planning for Larger Arrays Than Needed

To ensure sufficient renewable energy generation during extreme weather conditions, its advisable to build extra infrastructure beyond the minimum required. This approach involves over-investing in new technology to offset potential shortfalls during adverse weather.

Predicting Future Weather Conditions

Predicting future weather patterns by studying historical data can help build resilience in energy systems. While these predictions are effective for current or near-future plants, forecasting future weather conditions becomes challenging due to the unpredictability of climate change.

Using Data Modelling to Improve Weather Prediction

A more accurate method of predicting future weather conditions involves long-term data collection and projecting energy shortfalls caused by extreme weather. This process, known as data modelling, examines how climate change-induced extreme weather might impact future renewable energy generation.

Utilising Energy Storage

Energy generated during periods of high production can be stored and used during shortages. As renewable energy adoption increases, the demand for energy storage decreases, but it remains a viable solution for managing unpredictable power output during extreme weather events.

Expanding the Range of Renewable Energy Plants

Distributing renewable energy technology across a broader geographic area can protect against power generation drops caused by extreme weather. This strategy takes advantage of differing weather conditions in various locations, allowing unaffected areas to maintain higher productivity.

The Role of Smart Grids in Withstanding Extreme Weather Conditions

Smart grids, though still in their early stages, are emerging as a crucial tool for enhancing grid resilience during extreme weather events. These grids use technologies like sensors, forecasting algorithms, and battery storage systems to monitor and manage power distribution in real-time.

The advantage of smart grids lies in their ability to respond quickly to energy surges caused by extreme weather. By analysing real-time data on energy distribution, smart grids can make informed decisions to stabilise the grid.

Artificial Intelligence (AI) can also be integrated into smart grids to identify patterns in historical data and provide recommendations for managing energy spikes or surges, further enhancing grid resilience.

Addressing the vulnerabilities of renewable energy infrastructure in the face of extreme weather is crucial for the sustainability and reliability of the global energy supply. By implementing strategies like smart grid technology, expanding energy storage, and enhancing predictive modeling, we can mitigate the effects of climate change on renewable energy systems. Proactive planning and investment in resilient infrastructure will be key to ensuring that renewable energy continues to grow and thrive, even under the most challenging environmental conditions
