The Mainland Grid Made Headlines This Year. The Territories Never Stopped Living It.

Quick Takeaways

• Mainland grid risk actually went down in 2026. NERC's official assessment flags only 3 elevated-risk regions this year, down from 6 in 2025.
• That improvement doesn't reach the territories.
• Puerto Rico customers lose about 27 hours of power a year even without a hurricane, per EIA data. That's roughly 13 times the mainland average.
• USVI and Guam utilities are dealing with active, ongoing instability, not hypothetical risk.
• Island grids have no neighboring grid to pull emergency power from. When local generation falls short, there's no backup network to lean on.
• Most retailers won't ship lithium battery power stations to the territories, or they cancel the order once they realize what DG (dangerous goods) certification requires.
• Power Fit Shop does. We're DG-certified for lithium battery ocean freight to every U.S. territory, backed by our parent company's 20+ years and 64,000+ transactions of online selling experience.

2026 has been a good-news year for most of the continental U.S.

NERC's 2026 Summer Reliability Assessment is the industry's most authoritative forecast. It found that every assessment area in the Lower 48 can meet normal summer demand.

Over 58 GW of new solar, battery, and gas capacity got added since last summer.

Only three regions carry elevated risk this year: New England, the Pacific Northwest, and Saskatchewan, plus one localized concern in far-west Texas. That's down from six flagged regions in 2025.

That's good news for the mainland. It doesn't apply to Puerto Rico, Guam, Saipan, the U.S. Virgin Islands, Hawaii, or Alaska.

The territories aren't even on the interconnected grid NERC measures. They run on island grids. The data backs that up.

What the Numbers Actually Say

The average mainland U.S. customer loses under 2 hours of power a year.

The EIA's own tracking shows Puerto Rico customers lose about 27 hours a year. That's the baseline without counting hurricanes.

LUMA Energy operates Puerto Rico's transmission and distribution system. LUMA has told regulators directly that limited funding has reduced its ability to do preventive maintenance.

Equipment failures, not just storms, are the leading cause of outages there.

The U.S. Virgin Islands had back-to-back blackouts over a single weekend this past May. A mechanical failure at a power plant knocked out nearly 60% of St. Thomas.

The territory's utility ranks second in the country for both total outages and percentage of customers affected, according to outage-tracking data.

Guam Power Authority has issued standing warnings about rotating outages when demand outpaces supply during peak hours. That's a routine seasonal risk there, not a once-a-decade event.

This isn't a "watch list" or a scare headline. It's documented, ongoing reality for island grids that can't pull emergency power from a neighboring state the way the mainland can.

Why Island Grids Are a Different Problem

A mainland outage, even a bad one, usually means a utility can reroute power through a regional transmission network while it fixes the problem.

Puerto Rico, Guam, Saipan, the USVI, Hawaii, and Alaska don't have that option. Each one runs largely as its own isolated system.

When something fails, there's no neighboring grid to lean on. Everything runs on local generation and local reserves. If either falls short, outages follow.

Add in aging equipment and heavy dependence on imported fuel.

Add real hurricane or typhoon exposure for most of these islands on top of that. The baseline risk level ends up structurally higher than almost anywhere on the mainland, no matter what a given year's weather does.

Where Power Fit Shop Fits In

This is the exact gap we built Power Fit Shop. 

We're DG-certified for ocean freight shipping of lithium battery products. That means we can legally and safely ship Jackery, EcoFlow, and BLUETTI power stations to every U.S. territory: Puerto Rico, Guam, Saipan, Hawaii, Alaska, and the USVI.

Most retailers won't ship lithium batteries overseas at all. Some quietly cancel territory orders after the fact once they realize what's involved.

We built our shipping process specifically so that doesn't happen to you.

Frequent short outages (Guam, USVI, Puerto Rico's routine equipment failures):

A portable power station you can keep charged and ready is usually the right fit. Enough to run a fridge, fans, lights, phones, and medical devices through a multi-hour event.

EcoFlow and Jackery both make portable options built for exactly this. No installation, plug in what you need, done.

Extended, storm-driven outages (hurricane and typhoon season):

A larger-capacity system with solar charging capability matters more here, since you may be without grid power for days rather than hours.

BLUETTI, Jackery, and EcoFlow all offer larger-capacity systems that pair with solar panels, so you're refilling the battery every day the sun's out, not just running it down.

Whichever fits your situation, we ship it. DG-certified, all the way to your door, wherever in the territories that is.

"Won't Shipping to My Territory Void the Warranty?"

Short answer: no. The manufacturer's warranty on your Jackery, EcoFlow, or BLUETTI unit isn't affected by where you live.

The real problem is different. If your unit ever needs warranty service, most manufacturers have no way to pick it up from an island and ship it back for replacement. Lithium batteries are dangerous-goods freight. Most carriers won't touch that route at all.

So people get warranty approval, then get stuck. The manufacturer says yes, but there's no way to actually get the unit back and forth.

That's what our Replacement Shipping Service is for. Once your warranty claim is approved by the manufacturer, we handle the DG-certified logistics between your territory, our mainland freight forwarder, and the manufacturer.

You drop off your unit at the designated hub, and pick up your replacement when it comes back.

It's a paid add-on, sized to your unit (small, medium, or large power station), not something bundled free into every order.

But it exists specifically to close the one real gap in territory ownership: not "will my warranty be honored," but "can the unit actually get where it needs to go."
