The American Society of Civil Engineers just gave the U.S. energy grid a D+. Here’s what that letter grade actually means for your electricity bill — and why the next decade is going to look nothing like the last one.
Let’s start with that grade.
A D+ and not from a fringe think tank or a solar company with something to sell you. From the American Society of Civil Engineers — the same organization that evaluates bridges, dams, and highways. These are the people who look at infrastructure for a living, and their verdict on the electrical system powering your home right now is: D+.
In infrastructure terms, that isn’t a “could use some work.” It means the system is in poor to fair condition, with significant deterioration, frequent failures, and serious risk of broader breakdown if left unaddressed. It means we’re running a 20th-century grid on momentum and deferred maintenance.
Here’s the uncomfortable part: that same grid is about to be asked to do something it has never done before.
A lot is about to hit the same old wires.
For most of the past two decades, electricity demand was pretty flat. Efficiency gains kept pace with population growth. Utilities could plan 20 years out with reasonable confidence.
That era is over.
What’s coming is a surge from every direction at once — and all of it runs through the same aging infrastructure. Electric vehicles. Heat pumps replacing gas furnaces. AI data centers that require enormous, uninterrupted power. A resurgence of American manufacturing. Each of these trends alone would stress the system. Together, they’re a different conversation entirely.
A few numbers worth knowing:
- 70% of U.S. transmission lines are over 25 years old (ASCE)
- 50%+ of distribution transformers are nearing end of operational life (ASCE)
- 4x the generation capacity will be needed for a fully electrified U.S. economy (J.P. Morgan)
- 30% of new electricity demand through 2030 will come from industry alone (J.P. Morgan)
The grid was built for the world we lived in. Not the one we’re building. And the gap between those two things has to be paid for by someone.
That someone is you.
This is already showing up on your bill.
Grid upgrades don’t pay for themselves. When utilities need to replace aging transmission lines, swap out failing transformers, and build new generation capacity, they file rate increase applications with state regulators. And regulators approve them — because the alternative is a grid that fails entirely.
PG&E customers on the Central Coast are already living this. Rates have been climbing steadily for years, and what we’ve absorbed so far is modest compared to what infrastructure analysts project over the next decade.
Illustrative PG&E Average Residential Rate (¢/kWh):
- 2018: ~18¢
- 2020: ~22¢
- 2022: ~28¢
- 2024: ~37¢
- 2028 (projected): ~50¢+
- 2031 (projected): ~62¢+

Think about what 50–60¢ per kilowatt-hour means in practice. The average home uses roughly 550–600 kWh a month. At today’s rates, that’s already a meaningful line item. At projected 2031 rates — before you factor in an EV or a heat pump — it becomes genuinely consequential.
For homeowners in Santa Cruz and Monterey Counties, this isn’t abstract. PG&E’s residential rates on the Central Coast have climbed more than 80% since 2018 — faster than nearly any other region in California. Customers in Aptos, Capitola, Scotts Valley, and Salinas are already spending $300–$500 a month during peak summer months, before any of that additional load.
The trajectory from here isn’t unclear. It’s just uncomfortable to look at directly.
And that’s before we even get to reliability. An aging grid under unprecedented demand doesn’t just get expensive — it gets unpredictable. Outages become more frequent. Wildfire-related shutoffs extend further into the year. The system becomes less trustworthy even as it becomes more costly.
A few things homeowners tend to get wrong.
“My bill is fine right now.” Of course it is. Infrastructure crises don’t announce themselves — they build slowly, then arrive all at once. The time to think about your exposure is before the next rate increase, not after you’ve spent a decade absorbing compounding increases with nothing to show for it.
Comparing today’s rates instead of tomorrow’s. Most people evaluate solar by comparing a monthly payment to their current utility bill. That’s the wrong math. The right question is: what will my bill look like in 2031, after EVs, heat pumps, and AI data centers have reshaped demand? The answer is a different conversation.
Treating energy costs as stable. For a long time, that assumption was reasonable. It isn’t anymore. McKinsey, NEMA, and the EIA all point the same direction: electricity consumption expanding dramatically through 2050. Rate volatility isn’t a temporary blip. It’s a structural feature of the grid now.
Staying on the grid is a bet you’re already making.
Here’s the part most homeowners don’t think about: doing nothing isn’t a neutral choice. It’s an active decision — a 25-year bet that a regulated monopoly managing D+ infrastructure will keep your power affordable and reliable enough to plan around.
You don’t get a vote on rate increases. You don’t get a say in capital spending. You absorb the cost of every deferred maintenance project, every grid modernization loan, every wildfire liability that works its way into the rate base. The utility decides. You pay.
Solar isn’t a product pitch — it’s a hedge against a future that’s already in motion. Predictable energy costs for 25 years, decoupled from the rate decisions of a utility navigating exponentially growing demand on a system that was already overdue for an overhaul when your kids were born.
The homeowners who lock in their energy costs in 2026 are the ones who’ll be telling their neighbors “I saw this coming” in 2032. The ones who wait will spend the next two decades funding grid upgrades through their utility bill — with no equity, no control, and no way out.
What to do next.
Allterra Solar has helped hundreds of Santa Cruz and Monterey County homeowners lock in their energy costs before the next rate increase. If you’re running the numbers, the best time to do it is before your summer bill arrives — not after.
The assessment is free, there’s no obligation, and it takes less than 20 minutes. You’ll walk away knowing exactly what your home could save over the next 10, 15, and 25 years — based on your actual usage, your roof, and where PG&E rates are heading.
