Grid Hardening’s Costly Data Problem that Overruns Grants and Mandates

The U.S. Department of Energy is rolling out billions of dollars in grants to fund a nation-wide grid hardening initiative. Grid hardening refers to investing time and money into making the electricity grid more resilient to disruptions from weather, wildfire, load growth, cyberattacks, and other disruptive events that can cause mass outages.

In many cases, the most impactful improvement to grid resilience that utilities can make is burying power lines. As wildfires become more frequent and more devastating, underground power lines are the best defense against having the grid collapse as a result. Many other events, like hurricanes and vehicle collisions, have their impact on the grid minimized with underground power. It is no surprise that many of the largest projects launched under this grid hardening initiative have involved moving power lines underground.

But when it comes time to dig, “no surprise” is a pipe dream. Running into conflicting schedules, unverified subsurface locating, permit mapping ambiguities, rocky or otherwise challenging soil conditions, and more is par for the course. Minimizing these challenges requires extensive proactive research. Try to plow ahead regardless and you’re liable to need heavy rework, plan redrafts, and put yourself at risk of a catastrophic line strike to existing gas utilities. Either way, your cost-per-mile is liable to balloon well past where your grants and mandate have budgeted you.

Fortunately, cutting-edge technological solutions allow your process to scale without destroying your budget. Read on to learn about the state of grid hardening projects and grants, how PG&E is delivering on their grid burying mandate, and how CivilGrid can ensure the same for you.

The Costs and Opportunities of Grid Hardening in 2026

The Department of Energy’s Grid Resilience and Innovation Program (GRIP) has set aside $10.5 billion from FY22 to FY26 to prevent outages and enhance grid resilience. From this pool, billions have already been awarded for over 100 projects across the nation, with more projects and grants continuing to be awarded. Utility companies are being given mandates and accompanying support to carry out massive infrastructural projects on the grid.

We’ll use GRIP as an example of how these programs work, but many others like it are rolling out at the state level. In some states, like California, wildfires are the primary motivator for hardening, whereas hurricanes, tornadoes, and other events are high priorities in others. Nationwide, these concerns are fuelling a new need for undergrounding. These grants can open up major opportunities for utilities, but come with their own challenges to consider:

GRIP requires cost sharing

Whatever money is granted via GRIP is generally matched by the utility company. Without careful budget management, these projects can be devastating for the bottom line of the utility company.

Demand is vastly outpacing availability

Applications for projects have totaled over $50 billion in requested grants. This is far beyond what GRIP is capable of awarding. Projects continue to receive funding, so applying is still viable, but your budget must be competitive in order to stand a chance.

Cost-effectiveness will be scrutinized

Undergrounding power lines is the most robust protective measure, but it can be costly compared to other resilience measures, such as covered and insulated conductors (making them more resistant to fire, weather, etc., but not as resistant as buried lines). Without a competitive proposal for burying, utilities will be pushed to adopt stop-gap measures that leave them more susceptible to further costly incidents and outages.

Regulatory pressure will tighten margins

Grants awarded through GRIP or other projects will be subject to a litany of checks, validations, and caps. At the federal level, this includes cost-reporting obligations, while at the state level it could mean annual cost caps, unit cost caps, cost-benefit thresholds, and other standards to protect ratepayers. Understanding the exact impact of your projects is necessary to make clear benefit statements that prove the money is well spent.

The Bottom Line is the Bottom Line

All of these challenges boil down to one thing: cost effectiveness is a must. If you want to get these mandates, receive these grants, and succeed on these projects, you need to minimize your per-mile cost.

How PG&E Built the Data Foundation First

A program only scales if its per-mile cost comes down predictably, and per-mile cost only comes down when crews stop hitting surprises. That’s a data problem before it’s a construction problem, and it’s where PG&E got ahead.

Across its capital project portfolio, PG&E has been running grid hardening projects through CivilGrid. Before CivilGrid, the pattern was familiar to anyone running infrastructure at scale: design teams waited on survey data, schedules slipped, permitting requirements surfaced late, and field crews absorbed the cost of excessive test holes and unexpected conflicts. Every surprise was a change order waiting to happen.

By moving site due diligence to the front of the project lifecycle, PG&E changed the sequence. Records research now starts at the preliminary work-in-progress stage, not after design is underway. Teams review execution, risk, and permit conflicts before finalizing work plans: identifying long-lead permits, overlapping paving projects, and utility conflicts while there’s still time and budget to plan around them. The results: reduced survey areas and pothole/test hole counts, earlier permit filings, and less design rework. PG&E reported reduction by 40% of field research and survey activities.

That’s the same cost/savings equation every utility now faces under a grid-hardening mandate. Undergrounding at scale means trenching mile after mile through sometimes congested, often poorly documented, and always costly subsurface corridors. The utilities that hold their per-mile cost will be the ones that know what’s underground before they dig and can prove it. PG&E built that foundation first. CivilGrid is how other IOUs can do the same.

The short version

• Federal and state programs like GRIP are funding grid hardening at scale, and undergrounding is often the most impactful investment.
• Cost sharing, heavy competition, and regulatory scrutiny mean per-mile cost decides who wins grants and succeeds on projects.
• PG&E moved site due diligence to the front of the project lifecycle with CivilGrid, reducing field research and survey activities by 40%.
