In this week’s episode, host Daniel Raimi talks with Will Gorman, a research scientist at Lawrence Berkeley National Laboratory, about the interconnection queue. The interconnection queue is the waiting list for developers that hope to connect power plants to the electric grid; regulators must first study the potential effects of connecting a plant to the grid before moving forward with a project. Gorman discusses the reasons for recent growth in queue wait times, the costs that are associated with connecting a new power plant to the grid, a new federal regulation that aims to improve the interconnection queue, and additional reforms that could speed up the process of connecting new power plants to the grid.

Most POWER readers are probably familiar with levelized cost of energy (LCOE) and levelized value of energy (LVOE) as metrics used to help evaluate potential power plant investment options. 
LCOE measures the average net present cost of electricity generation over a facility’s lifetime. It includes capital costs, fuel costs, operation and maintenance (O&M) costs, financing costs, expected capacity factor, and project lifetime. Meanwhile, LVOE goes beyond LCOE by considering the actual value the power provides to the grid, including time of generation (peak vs. off-peak), location value, grid integration costs and benefits, contributions to system reliability, environmental attributes, and capacity value.
Some of the key differences stem from the perspective and market context each provides. LCOE, for example, focuses on pure cost comparison between technologies, while LVOE evaluates actual worth to the power system. Notably, LCOE ignores when and where power is generated; whereas, LVOE accounts for temporal and locational value variations. Concerning system integration, LCOE treats all generation as equally valuable, while LVOE considers grid integration costs and system needs.
“Things like levelized cost of energy or capacity factors are probably the wrong measure to use in many of these markets,” Karl Meeusen, director of Markets, Legislative, and Regulatory Policy with Wärtsilä North America, said as a guest on The POWER Podcast. “Instead, I think one of the better metrics to start looking at and using more deeply is what we call the levelized value of energy, and that’s really looking at what the prices at the location where you’re trying to build that resource are going to be.”
Wärtsilä is a company headquartered in Finland that provides innovative technologies and lifecycle solutions for the marine and energy markets. Among its main offerings are reciprocating engines that can operate on a variety of fuels for use in electric power generating plants. Wärtsilä has modeled different power systems in almost 200 markets around the world. It says the data consistently shows that a small number of grid-balancing gas engines in a system can provide the balancing and flexibility to enable renewables to flourish—all while maintaining reliable, resilient, and affordable electricity. 
Meeusen noted that a lot of the models find engines offer greater value than other technologies on the system because of their flexibility, even though they may operate at lower capacity factors. Having the ability to turn on and off allows owners to capture high price intervals, where prices spike because of scarcity or ramp shortages, while avoiding negative prices by turning off as prices start to dip and drop lower. “That levelized value is one of the things that we think is really important going forward,” he said.
“I think what a lot of models and planning scenarios miss when they look at something like LCOE—and they’re looking at a single resource added into the system—is how it fits within the system, and what does it do to the value of the rest of their portfolio?” Meeusen explained. “I call this: thinking about the cannibalistic costs. If I look at an LCOE with a capacity factor for a combined cycle resource, and don’t consider how that might impact or increase the curtailment of renewable energy—no cost renewable energy—I don’t really necessarily see the true cost of some of those larger, inflexible generators on the system. And, so, when we think about that, we really want to make sure that what we’re covering and capturing is the true value that a generator has in a portfolio, not just as a standalone resource.”


178. Why LVOE May Be a Better Decision-Making Tool Than LCOE for Power Companies

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.
