Energy security represents one of Taiwan’s most pressing challenges. With virtually no domestic fossil fuel resources and limited renewable energy potential relative to its needs, the island imports approximately 98% of its energy. The semiconductor fabrication plants that drive the economy are particularly energy-intensive, requiring uninterrupted power supplies to maintain their precision manufacturing processes. Any disruption in electricity can halt production lines worth billions of dollars, making grid stability and efficient power generation not merely infrastructure concerns but fundamental pillars of Taiwan’s economic competitiveness.
This reality has driven the island to pursue cutting-edge power generation technologies, including advanced combined cycle plants that can deliver maximum efficiency from imported natural gas. One such plant, the Sun Ba II facility, entered commercial operation in May 2025. It was recently recognized as a 2025 POWER Top Plant award winner.
“That this project got recognized with your power plant award, I think this is really a nice story and a nice finish I would never have expected when I came here,” Thomas Ringmann, director of Business Development with Siemens Energy, said as a guest on The POWER Podcast.
Sun Ba II is a 2 x 1 multi-shaft configuration, which means there are two gas turbines and two heat recovery steam generators (HRSGs) serving one steam turbine. The gas turbines and the steam turbine each have their own generators. “We have used in this project our latest and biggest gas turbine—the SGT-9000HL,” Ringmann explained. “The steam turbine is a SST-5000, so that’s a triple-pressure steam turbine with a combined HP [high-pressure] and IP [intermediate-pressure] turbine, and a dual-flow LP [low-pressure] turbine. Also, we had an air-cooled condenser, condensing the steam from that steam turbine, and we had a three-pressure reheat HRSG, which was of Benson-type technology.”
The project began at the peak of the COVID pandemic, which presented a large challenge. “Every project meeting, every design meeting, every coordination meeting were all done online,” Andy Chang, project manager with Siemens Energy, said. “Everything was done online, because nobody can travel. We just had to figure this out.”
Effective collaboration among project partners was a key to success. “The collaboration is not only with our consortium partner—CTCI, an EPC [engineering, procurement, and construction] company—but actually with also the customer, Sun Ba Power,” Ewen Chi, sales manager with Siemens Energy, said. “Everybody has the same target, which is to bring power on grid as soon as possible. So, with this same-boat mentality—everybody sitting in the same boat and rowing toward the target—actually helped the project to be successful and to overcome many challenges.” Chang agreed that on-time completion was only possible with all parties maintaining a collaborative spirit.
“This power plant right now is predominantly running on baseload operation,” Ringmann reported. “So, given that high grade of operations along with a high gas price, the efficiency of our turbines actually is a key contributor to an economic value of the customer.”
Meanwhile, the lessons learned from this first deployment of HL technology in Taiwan are being applied to a new project. Siemens Energy and CTCI are now collaborating on the Kuo Kuang II power plant, which is under construction in Taoyuan, northern Taiwan. “Because we have this momentum and this mentality from Sun Ba II execution, now each side, they decided that they will keep their core team member from both sides, and they will continue to cherish this partnership with the next project,” Chang reported.

Despite nuclear power’s unmatched ability to produce reliable, carbon-free energy at scale, it is often dismissed by clean energy advocates in favor of renewable resources like wind and solar. Cost arguments and public misconceptions around safety and radioactive waste have kept it out of many mainstream climate strategies. But as Tim Gregory argues in his new book Going Nuclear: How Atomic Energy Will Save the World, this exclusion may be the greatest obstacle to achieving net zero goals. In fact, Gregory says in his book “net zero is impossible without nuclear power.”
“Claiming renewables on their own are enough to replace fossil fuels is underestimating the challenge of achieving net zero,” Gregory said as a guest on The POWER Podcast. “Fossil fuels have basically defined the world order for the last couple of centuries, and to think that we can replace them with wind power and solar power, which are fundamentally tied to the whims of the weather, and the rotation of the planet in the case of solar, is really underestimating the scale of the challenge,” he said.
“We need power that comes in enormous quantities exactly where we need it and when we need it,” Gregory continued. “I don’t want to live in a world without solar panels or wind turbines, but to think that they can do it on their own, I think, is honestly naive. We need something that’s reliable to compensate for the intermittence of renewables, and nuclear power would be absolutely perfect for that.”
Notably, innovative companies and many government leaders around the world are backing nuclear power projects. “Big tech in North America has really cottoned on to these small modular reactors,” said Gregory. “Meta, Google, Microsoft, and Amazon are all going to be using small modular reactors to power their data centers. … This isn’t just a pipe dream—this is actually happening now in real time. … It’s been very, very encouraging watching that unfold.”
Public perceptions on nuclear power are also trending in a positive direction, and the movement seems to be bipartisan. “It’s very, very encouraging that more than half of people in the UK either strongly support or tend to support nuclear power. Strong opposition to nuclear power, according to the latest poll, is actually below 10%,” Gregory reported. “As such, the two major political parties in the UK—that’s the Labor Party, which is kind of our left leaning party, and the Conservative Party, which is our right leaning party—they both support the massive expansion of nuclear power, which is really, really nice actually. It’s maybe something that both sides of the political spectrum can agree on.”
The same is true in the U.S., where both Democrats and Republicans have gotten behind nuclear power. A case in point is the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act, which was signed into law in July 2024. It passed with overwhelming bipartisan support in the Senate with a vote of 88–2, and in the House of Representatives with a vote of 393–13.
“If your politics has you more concerned with environmental stewardship, and climate change, and phasing out fossil fuels, and getting rid of oil from the energy system, then nuclear power is for you. But then at the same time, if your politics has you perhaps more leaning towards economic growth, and the economy, and prosperity, and all that kind of thing, then nuclear power is for you as well, because it provides the energy that enables that economic growth,” Gregory said. “And so, it’s actually very, very encouraging to see that, at least in most countries, nuclear power is not a partisan issue, which is all too rare in the world these days.”
