Taipingling Unit 2 in Guangdong is the latest of China's domestically designed third-generation reactors to start supplying power

August 3rd, 2026: Taipingling Unit 2 enters commercial operation

Overview

Updated Aug 4

A new 1,116-megawatt reactor in Guangdong Province began commercial operation on August 3, 2026. It is the second unit at the Taipingling plant and the first Hualong One reactor serving the Greater Bay Area, the region linking Guangzhou, Shenzhen, Hong Kong, and Macao.

China's State Council approved eight more reactors on July 31, six of them Hualong One. Two of those six, at the same Taipingling site, are designated as the first test beds for Hualong One 2.0, an upgraded version of the design. China now has 47 Hualong One units operating or under construction worldwide.

Why it matters

China is adding low-carbon baseload power at a pace no other country matches, using a reactor it owns outright and can build in batches.

Tap a bar to jump to that date

  1. Taipingling Unit 2 enters commercial operation

    Latest Milestone

    CGN declares the 1,116-MW reactor commercial after a 168-hour continuous run, completing the plant's first phase and marking the first Hualong One serving the Greater Bay Area.

  2. Changjiang Unit 3 connects to grid in Hainan

    Milestone

    Hainan's first Hualong One reactor sends electricity to the grid for the first time, about three weeks after reaching first criticality on July 10. The unit must complete further commissioning and performance tests before entering commercial operation.

  3. State Council approves eight new reactors across four sites

    Regulatory

    China's State Council approved four nuclear projects totaling eight units and roughly RMB 170 billion in investment. Six use Hualong One; the two at Taipingling (Units 5 and 6) are the first reactors designated as Hualong One 2.0 demonstration plants, while two Guohe One units are approved for Laiyang in Shandong.

  4. First grid connection

    Milestone

    Taipingling Unit 2 sends its first electricity to the grid.

  5. First criticality reached

    Milestone

    The reactor sustains its first controlled chain reaction.

  6. Fuel loading completed

    Milestone

    Crews finish loading all 177 fuel assemblies into the reactor core.

  7. Taipingling Unit 2 licensed

    Regulatory

    China's National Nuclear Safety Administration issues the operating license for the unit.

  8. Zhangzhou Unit 2 goes commercial

    Milestone

    Another Hualong One unit enters commercial service, part of a wave of 2026 startups.

  9. World's first Hualong One starts up

    Milestone

    Fuqing Unit 5 enters commercial operation, making China the fourth country to field its own third-generation reactor design.

Scenarios

1

Taipingling Unit 3 starts construction on schedule

Likely Resolves by Aug 3, 2027

Discussed by: World Nuclear News, CGN project filings

The Taipingling site is planned for six Hualong One reactors. With the first phase now complete, attention turns to the next pair. If China's approval pace holds, first concrete for a third unit follows within roughly a year of the second going commercial.

2

China hits 110 gigawatts of nuclear capacity by 2030

Possible Resolves by End of 2030

Discussed by: World Nuclear Association, China's 15th Five-Year Plan, Bloomberg

Beijing's stated target is to roughly double operating nuclear capacity to 110 gigawatts by 2030. Reaching it depends on units like Taipingling coming online on time across dozens of sites. Analysts see the goal as reachable given the current construction pipeline, though grid and financing bottlenecks could slow it.

3

A new country signs to buy a Hualong One reactor

Uncertain Resolves by Aug 3, 2028

Discussed by: NucNet, World Nuclear News, CNNC export briefings

China has exported the Hualong One to Pakistan and pitched it elsewhere. As the domestic fleet grows and the design racks up operating years, China may land a firm order from a buyer that has not previously ordered one. A signed contract, not a memorandum, would mark real export traction.

4

Taipingling Phase III (Hualong One 2.0) breaks ground by end of 2027

Likely Resolves by End of 2027

Discussed by: World Nuclear News, Global Times, CGN project filings

China approved Taipingling Units 5 and 6 in July 2026 as the first Hualong One 2.0 demonstration reactors. If site preparation and regulatory steps move at the pace set by earlier phases, first concrete could follow within 12 to 18 months of approval. A delay in licensing the updated design or in site readiness could push that back past 2027.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

1974–1990

France's nuclear buildout (1974–1990)

After the 1973 oil shock, France launched the Messmer Plan and built 56 reactors in about 15 years using a small number of standardized designs. State utility EDF and reactor builder Framatome repeated the same models across the country.

Then

France went from oil-dependent to generating most of its electricity from nuclear power within two decades.

Now

Nuclear still supplies around 70% of French electricity, and standardization kept build costs lower than in most Western peers.

Why this matters now

China is running the same playbook: one owned design, repeated at scale, driven by the state. It shows standardization can work when a single builder controls the program.

2013–2024

US Vogtle expansion (2013–2024)

The United States tried to build two Westinghouse AP1000 reactors at Georgia's Vogtle plant. The project ran years late and roughly doubled in cost, and Westinghouse filed for bankruptcy in 2017 partly because of it.

Then

The two units eventually came online in 2023 and 2024 at a cost far above budget.

Now

The overruns chilled new US reactor orders and became a cautionary tale about first-of-a-kind builds.

Why this matters now

Vogtle shows the cost trap China is trying to avoid. Repeating a standardized design across many sites is meant to keep schedules and budgets under control.

January 2021

Fuqing Unit 5, first Hualong One (2021)

CNNC brought the world's first Hualong One reactor online at Fuqing, giving China its own third-generation design with full intellectual property rights. It joined the US, France, and Russia as countries fielding home-grown Gen III reactors.

Then

China stopped depending on foreign vendors like Westinghouse and Areva for its newest large reactors.

Now

The design became the backbone of China's domestic program and its main nuclear export product.

Why this matters now

Taipingling Unit 2 is one of many copies of that first reactor. The 2021 milestone is why China can now build the same unit again and again.
