Frequently Asked Questions (FAQs)

A BESS is essentially a large battery that collects and stores energy when power demand is low in order to supplement energy needs during peak power demand. This technology is important for a more efficient and reliable community energy system.

Most modern cruise ships use a diesel-electric system, where diesel generators produce electricity that then powers the ship's propulsion and all onboard electrical needs. The ships’ power generators produce emissions that can decrease air quality, particularly when they are docked and not moving. A BESS will allow cruise ships to turn off their diesel generators and reduce emissions while docked in Seward. A BESS is needed because there is not enough existing power available in Seward to meet the ships’ large demand. A BESS will allow for a steady power supply when cruise ships dock without jeopardizing the existing electric supply.

The shore power project will eliminate cruise ships’ diesel emissions while they are docked and add a large power consumer to Seward’s locally-owned electric grid. The BESS will also provide an alternative power source, which could be used if the local power system is disrupted.

A large customer like cruise ships will provide the City of Seward with additional funds for operations and maintenance costs and help to stabilize the electricity rates for ratepayers.

Ninety percent of the project cost will be covered by an Environmental Protection Agency 2024 Clean Ports Program: Zero-Emission Technology Deployment Competition grant that was awarded to the City of Seward. The remainder of the project costs will be covered by private funds from the Seward Company.

BESS planning and design started in late summer 2025 and is ongoing. Project presentations at the Kenai Peninsula Borough assembly and Seward City Council meetings are planned for December 2025 and January 2026. Check back at this site for updates.
