Princess Cruises is marking a quarter century of plugging into Juneau’s hydroelectric grid instead of idling engines at the pier. The anniversary is more than corporate nostalgia for Alaska travelers who care about air quality and dockside noise on summer port days.
In a July 27, 2026 release, the line says it was the first cruise company to connect a ship to Juneau shore power in 2001, and that Princess ships still connect whenever power is available today.
- Milestone: 25 years of Juneau shore power operations, celebrated July 27, 2026.
- Connections: Princess cites 1,725 shore power connections in Juneau over the program.
- Power used: About 123.7 million kilowatt-hours of local hydroelectric power.
- Emissions claim: About 84,534 metric tons of emissions avoided under company accounting.
- Traveler takeaway: Princess still plans to plug in at Juneau when shore power is available.
Why the anniversary lands in peak Alaska season
Juneau remains one of the busiest single ports in the Alaska cruise calendar. Multiple large ships can share the same waterfront morning, which is why local air quality and pier congestion stay traveler-relevant even when excursions go smoothly.
Shore power does not thin the crowd on South Franklin Street. It does reduce the need for a connected ship to generate hotel load with main engines while alongside, which is the part guests hear and smell if they are on a low balcony facing the pier.
Alaska 2026 sailings are already deep into the peak window. An anniversary package will not create new cabins, but it does remind planners that infrastructure at the dock is part of product quality alongside dining packages and Glacier Bay access.
Competitors continue to expand Alaska capacity while Juneau manages passenger caps and berth rules. That political and operational context is why a long-running shore power partnership still matters as more plug-ready ships arrive.
What shore power changes on a Juneau day
Shore power, sometimes called cold ironing, lets a docked ship shut down main engines and pull electricity from shore. In Juneau that power is described as surplus hydroelectric energy from the local utility, Alaska Electric Light and Power.
For guests, the practical effects are quieter decks and less exhaust near the pier when the system is connected. It does not change Glacier Bay permits, excursion seating, or whether Mendenhall has capacity that afternoon.
The official Princess Cruises PR Newswire anniversary release frames the 2001 project as the first cruise-line shore power connection in Juneau. The City and Borough of Juneau and AEL and P are named as long-running partners.
Independent industry history has long treated that Juneau project as an early global model. Seatrade Cruise Review coverage of the earlier 20-year mark recounts the same city, utility, and Princess partnership that started cold-ironing in summer 2001.
Carnival Corporation, which owns Princess, says roughly 75 percent of its global fleet of more than 90 ships can already plug into shoreside electricity. The same note says only about 3 percent of world ports, just over 40 ports, have cruise berths equipped for shore power.
The numbers Princess is using
Princess lists 1,725 shore power connections in Juneau across 25 years. That is a cumulative operations count, not a promise that every 2026 call will plug in for the full day.
The line also cites 123,668,490 kilowatt-hours of hydroelectric power used and 84,533.60 metric tons of emissions avoided.
Treat those as company-reported totals, not independent audits published in the anniversary package.
Community Partnership, or COPA, credits of 11,242,400 dollars are listed as benefits returned to Juneau. Those credits are a local partnership mechanism, not a refund line on a guest cruise invoice.
Juneau Mayor Beth Weldon is quoted praising the public-private partnership and looking toward future shore power expansion in the port. AEL and P CEO Alec Mesdag is quoted on the engineering difficulty of connecting large ships to a small, isolated grid.
Princess president Gus Antorcha ties the anniversary to Alaska stewardship language and nearly 60 years of Princess sailing in the state. Marketing tone aside, the operational claim travelers can test is simpler: when the berth and power window allow it, Princess still plugs in.
What Alaska cruise planners should do with this
Do not book a Princess Alaska cruise solely because of a shore power anniversary. Book because the itinerary, ship, price, and date fit.
Then treat shore power as a quality-of-port-day factor when comparing berths and lines that can connect in Juneau.
If you are sensitive to dockside exhaust or noise, prefer ships and lines that publish shore power capability and confirm Juneau connection practice. Capability on the ship is not enough if the berth that day lacks power or capacity.
Check your sailing documents for port times and berth notes, then recheck closer to departure. Juneau’s passenger caps and berth assignments can reshape which ships call on which days even when the shore power system itself is ready.
Use Deep Arrival’s Princess Cruises planning hub when comparing ships and Alaska deployments. For the capital port day itself, pair that with things to do in Juneau so the shore plan does not depend on marketing language alone.
Travelers comparing Alaska 2026 and 2027 inventories should also watch which competing lines can connect in Juneau and which still burn engines at the dock. The anniversary does not invent new ports, but it does keep Princess on the short list for guests who rank pier air quality highly.
| If you… | What to do |
|---|---|
| Already hold a Princess Juneau call | Keep the booking; treat shore power as a pier comfort factor, not a new itinerary change. |
| Compare Alaska lines on air quality | Prefer ships that can connect to shore power and ports that can supply it. |
| Care mainly about glaciers and wildlife | Rank itinerary and ship size first; shore power is a secondary pier detail. |
| Watch port congestion rules | Track Juneau passenger caps and berth assignments separately from the anniversary. |
| Want quieter morning decks | Ask whether your sailing is scheduled on a powered berth when final documents post. |
- Berth power windows: Connection still depends on available shore power when the ship arrives.
- Fleet capability versus port capability: A plug-ready ship cannot connect at a berth that lacks infrastructure.
- Juneau capacity rules: Passenger caps can change which ships call even when shore power is ready.
- Expansion plans: Local officials say they want more shore power capacity, but timelines are not a guest booking guarantee.
One concrete traveler scenario is a family sailing Princess in peak July. They can still get a busy downtown day if three ships share the waterfront.
Shore power helps the pier environment for the connected ship. It does not thin the sidewalks to the tram or the buses to Mendenhall Glacier.
If air quality at the dock is a personal priority, ask your travel agent or the line whether your berth historically connects and whether your ship class is shore-power equipped. Then build the rest of the day around timed tickets and weather, not the anniversary press release alone.
What did Princess announce about Juneau shore power?
Princess is marking 25 years since it first connected a ship to Juneau shore power in 2001, and says ships still connect whenever power is available.
Does shore power change my shore excursion plan?
No. It can reduce engine noise and local emissions at the dock, but excursions, weather, and port capacity still control the day.
How many connections does Princess claim?
The anniversary package cites 1,725 Juneau shore power connections and about 123.7 million kilowatt-hours of hydroelectric power used.
Can every cruise ship in Juneau plug in today?
No. Carnival Corporation notes only a small share of world cruise ports have equipped berths, even as more ships become plug ready.
