Strengthening US Grid Reliability Against Climate Change, Energy Transition and Increasing Costs

CLIMATE EVENTS AND GRID RESILIENCE

Extreme weather events are becoming more intense and frequent, directly impacting the stability of power systems. Data from the National Oceanic and Atmospheric Administration (NOAA) shows that billion-dollar weather disasters in the US have quadrupled in frequency over the past four decades.¹ Wildfires, hurricanes, and winter storms are causing widespread outages and forcing utilities to make significant investments in grid hardening strategies.

However, these investments come at a time of rising costs. Inflation has driven up the price of commodities, labor and infrastructure upgrades. Meanwhile, regulators are resistant to passing on costs to customers through higher rates. Utilities must therefore find ways to improve grid resilience while maximizing efficiency and minimizing financial impact. This requires a strategic balance between physical infrastructure investment and digital transformation to optimize grid performance.

THE ENERGY TRANSITION AND GRID COMPLEXITY

The rapid shift towards renewables makes the grid more complex to manage. Unlike traditional fossil fuel power plants that provide consistent, centralized generation, energy sources such as wind and solar are variable and decentralized. Instead of unidirectional power moving from generation plants to customers, energy is now being injected at multiple points, from rooftop solar panels to large-scale wind farms located far from population centers.

Connecting remote renewables to the grid requires major investment in new transmission infrastructure, which is often delayed by regulatory hurdles and permit backlogs. Wind and solar, which are subject to interruptions, require an extensive storage network. While battery costs are declining, supply chain dependencies, particularly on overseas manufacturing, bring new risks. 

To build a grid that can handle this evolving landscape, energy firms should align physical assets with digital transformation strategies such as real-time data analytics, automation, and demand-response approaches that dynamically balance supply and demand. 

THREE PILLARS OF GRID RELIABILITY

To navigate these challenges, Capco suggests that energy businesses explore three key areas that can contribute to more resilient and future-proof infrastructures.

1. Data governance and standardization

Data is at the heart of grid modernization, enabling utilities to capture an accurate picture of the grid for day-to-day management and decide where to focus attention and investments.  

However, utilities often struggle with siloed data across legacy systems, making it difficult to gain a holistic view of grid operations. Establishing robust data governance frameworks allows utilities to standardize and integrate data, enabling more effective use of analytics and AI-driven decision-making. By retrofitting sensors onto existing grid infrastructure, utilities can enhance real-time monitoring, predict equipment failures before they occur, and optimize maintenance schedules to reduce downtime and costs.

The good news is that the cost of sensors has dropped significantly in recent years, making large-scale deployment more feasible.² By investing in strong data governance and leveraging modern analytics tools, utilities can unlock new efficiencies and improve overall grid resilience.

2. Technology integration

A modern grid requires seamless integration between traditional infrastructure and new digital technologies. However, many utilities operate with fragmented systems that create inefficiencies and hinder real-time decision-making. Integrating IT and operational technology (OT) systems is critical to drive better coordination across the organization.

For example, advanced distribution management systems (ADMS) and energy management systems (EMS) can provide utilities with greater visibility into grid performance, enabling them to respond to disruptions more proactively. Additionally, the rise of distributed energy resources (DERs), such as community solar and battery storage, requires smarter grid architectures that can dynamically manage energy flows. Implementing technologies that facilitate data exchange between these distributed assets and central control systems is key to enhancing grid stability.

3. Cybersecurity

As utilities digitize their operations, cybersecurity has become a critical component of grid resilience. The energy sector is a prime target for cyberattacks, with threats ranging from ransomware attacks to state-sponsored intrusions. The 2021 Colonial Pipeline ransomware attack underscored the vulnerabilities within critical infrastructure, demonstrating how a single breach can disrupt essential services on a massive scale.³

To safeguard against these threats, utilities must adopt a proactive cybersecurity strategy that includes network segmentation, real-time threat monitoring and AI-driven anomaly detection. Additionally, integrating cybersecurity into overall grid modernization efforts can mitigate the risk of introducing additional vulnerabilities during change projects. 

Investing in robust cybersecurity measures is no longer optional – it is essential for maintaining grid reliability in an increasingly digital world.

THE PATH FORWARD

By focusing on these three pillars, energy businesses can build a more resilient grid that can withstand the impacts of climate change, adapt to the complexities of the energy transition and mitigate rising operational costs. This approach achieves not only short-term reliability but also long-term sustainability, enabling utilities to navigate the evolving energy landscape with confidence.

By leveraging a combination of industry knowledge, cutting-edge technology, and strategic insights, energy businesses can future proof their infrastructures and remain competitive in an increasingly complex energy environment.
