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.

As the presidential inauguration loomed on the horizon in January this year, the U.S. Department of Energy’s (DOE’s) Loan Programs Office (LPO) published a “year-in-review” article, highlighting accomplishments from 2024 and looking ahead to the future. It noted that the previous four years had been the most productive in the LPO’s history.
“Under the Biden-Harris Administration, the Office has announced 53 deals totaling approximately $107.57 billion in committed project investment––approximately $46.95 billion for 28 active conditional commitments and approximately $60.62 billion for 25 closed loans and loan guarantees,” it said.
Much of the funding for these investments came through the passing of the Bipartisan Infrastructure Law (BIL) and the Inflation Reduction Act (IRA). The LPO reported that U.S. clean energy investment more than doubled from $111 billion in 2020 to $236 billion in 2023, creating more than 400,000 clean energy jobs. The private sector notably led the way, enabled by U.S. government policy and partnerships.
“There were 55 deals that we got across the finish line,” Jigar Shah, director of the LPO from March 2021 to January 2025, said as a guest on The POWER Podcast, while noting there were possibly 200 more projects that were nearly supported. “They needed to do more work on their end to improve their business,” he explained. That might have meant they needed to de-risk their feedstock agreement or their off-take agreement, for example, or get better quality contractors to do the construction of their project.
“It was a lot of education work,” Shah said, “but I’m really proud of that work, because I think a lot of those companies, regardless of whether they used our office or not, were better for the interactions that they had with us.”
A Framework for Success
When asked about doling out funds, Shah viewed the term somewhat negatively. “As somebody who’s been an investor in my career, you don’t dole out money, because that’s how you lose money,” he explained. “What you do is you create a framework. And you tell people, ‘Hey, if you meet this framework, then we’ve got a loan for you, and if you don’t meet this framework, then we don’t have a loan for you.” Shah noted that the vast majority of the 400 to 500 companies that the LPO worked closely with during his tenure didn’t quite meet the framework.
Still, most of those that did have progressed smoothly. “Everything that started construction is still under construction, and so, they’re all going to be completed,” said Shah. “I think all in all, the thesis worked. Certainly, there are many people who had a hard time raising equity or had a hard time getting to the finish line and final investment decision, but for those folks who got to final investment decision and started construction, I think they’re doing very well.”
Notable Projects
When asked which projects he was most excited about, Shah said, “All of them are equally exciting to me. I mean, that’s the beauty of the work I do.” He did, however, go on to mention several that stood out to him. Specifically, he pointed to the Wabash, Montana Renewables, EVgo, and Holtec Palisades projects, which were all supported under the LPO’s Title 17 Clean Energy Financing Program, as particularly noteworthy.
Perhaps the most important of the projects Shah mentioned from a power industry perspective, was the Holtec Palisades endeavor. Valued at $1.52 billion, the loan guarantee will allow upgrading and repowering of the Palisades nuclear plant in Covert, Michigan, a first in U.S. history, which has spurred others to bring retired nuclear plants back online. “[It’s] super exciting to see our first nuclear plant being restarted, and as a result, the Constellation folks have decided to restart a nuclear reactor in Pennsylvania, and NextEra has decided to restart a nuclear reactor in Iowa. So, it’s great to have that catalytic impact,” said Shah.
