Chinese-owned BYD announced Monday it will supply Catalina Island’s largest resort with three electric buses to ferry tourists around the island.

The Catalina Island Company, which owns most of the island’s developed land, will get three 23-foot electric buses to replace a small fleet of 1950s, diesel-powered buses. The BYD buses carry about 18-20 people and can travel 125 miles on a two-hour charge.

Because of its small size, the city of Avalon restricts the number of vehicles that be brought to the island. Less than 5 percent are electric of the 400 vehicles on the island are electric, officials said.

The city also limits commercial vehicles; Avalon, the island’s only city, has only permitted just three in the last 12 years.

Most residents and tourists get around by golf cart, about 1,500 of which are in circulation.

The move announced this week follows other large public transit agencies, which are moving toward electric technology to reduce pollution.

Last year, Long Beach Transit added 10 electric buses to its fleet of 280. The transportation agency is slated to purchase 30 more and aims to eliminate diesel-powered buses completely by 2020.
