Three cities - -Guangzhou, Harbin and Xi'an -- are finalists in the race to host the Day 2023 event.

Nio (NYSE: NIO) has narrowed candidate cities for hosting its Nio Day 2023 event from 10 to three as planned, with the three cities competing to be the host of the electric vehicle (EV) maker's next annual event.

After the initial candidate cities were showcased, the Nio Day organizing committee nominated three cities as candidates to host Nio Day 2023, according to an article published today by Nio App.

The three cities are: Guangzhou, Harbin, and Xi'an

Guangzhou is the capital of Guangdong province in southern China and is home to the headquarters of Nio's local counterpart, (NYSE: XPEV).

Guangzhou has an urban population of 13.20 million, and Nio had 45 battery swap stations here as of July 28, as previously reported by CnEVPost.

Harbin is the capital of northeast China's Heilongjiang province, where winters are long and cold and the natural environment is considered unfriendly to EVs.

Harbin has an urban population of 5.03 million, and as of July 28, Nio had six battery swap stations there.

Xi'an, the capital of Shaanxi province in northwest China, has an urban population of 7.4 million, and as of July 28, Nio had 28 battery swap stations here.

Nio had 1,591 battery swap stations in China as of July 28. The latest figure as of August 5 was 1,643.

Nio hosted its first Nio Day in 2017, and from 2020 onwards, it left the choice of the city where Nio Day is held up to the users in the community to decide together.

Nio requires that the candidate cities for hosting the new Nio Day events have not hosted a Nio Day in the past 8 years. Since 2017, Beijing, Shanghai, Shenzhen, Chengdu, Suzhou, and Hefei have hosted Nio Day events.

For Nio Day 2023, candidate cities will need to have venues available for 14 consecutive days from December 1 to December 31, 2023, and the event's host day will be set on a Saturday, according to Nio's previously released requirements.

On July 25, 10 cities -- Dalian, Guangzhou, Harbin, Haikou, Hangzhou, Jinhua, Kunming, Tianjin, Xi'an, and Zhengzhou -- were added to the Nio Day 2023 shortlist after an initial venue check of the applicant cities by the Nio Day organizing committee.

Today, Guangzhou, Harbin, Haikou, Hangzhou, Kunming, Tianjin, Xi'an and Zhengzhou took part in the bid presentation session of Nio Day 2023, while Dalian and Jinhua withdrew their bids due to factors including venues, according to an article in Nio App.

From August 7 to August 11, Nio will showcase the three cities in its mobile app, according to the company's previously announced plans.

From August 11 to August 13, users will be able to vote for the host city they support in the Nio App.
