Most POWER readers are most likely accustomed to levelized price of power (LCOE) and levelized worth of power (LVOE) as metrics used to assist consider potential energy plant funding choices.
LCOE measures the typical web current price of electrical energy technology over a facility’s lifetime. It consists of capital prices, gasoline prices, operation and upkeep (O&M) prices, financing prices, anticipated capability issue, and mission lifetime. In the meantime, LVOE goes past LCOE by contemplating the precise worth the ability gives to the grid, together with time of technology (peak vs. off-peak), location worth, grid integration prices and advantages, contributions to system reliability, environmental attributes, and capability worth.
A number of the key variations stem from the attitude and market context every gives. LCOE, for instance, focuses on pure price comparability between applied sciences, whereas LVOE evaluates precise price to the ability system. Notably, LCOE ignores when and the place energy is generated; whereas, LVOE accounts for temporal and locational worth variations. Regarding system integration, LCOE treats all technology as equally invaluable, whereas LVOE considers grid integration prices and system wants.
“Issues like levelized price of power or capability elements are most likely the incorrect measure to make use of in lots of of those markets,” Karl Meeusen, director of Markets, Legislative, and Regulatory Coverage with Wärtsilä North America, stated as a visitor on The POWER Podcast. “As a substitute, I feel one of many higher metrics to begin taking a look at and utilizing extra deeply is what we name the levelized worth of power, and that’s actually taking a look at what the costs on the location the place you’re attempting to construct that useful resource are going to be.”
Wärtsilä is an organization headquartered in Finland that gives revolutionary applied sciences and lifecycle options for the marine and power markets. Amongst its fundamental choices are reciprocating engines that may function on a wide range of fuels to be used in electrical energy producing crops. Wärtsilä has modeled totally different energy programs in nearly 200 markets around the globe. It says the information persistently exhibits {that a} small variety of grid-balancing gasoline engines in a system can present the balancing and adaptability to allow renewables to flourish—all whereas sustaining dependable, resilient, and inexpensive electrical energy.
Meeusen famous that loads of the fashions discover engines provide larger worth than different applied sciences on the system due to their flexibility, though they might function at decrease capability elements. Being able to activate and off permits house owners to seize excessive value intervals, the place costs spike due to shortage or ramp shortages, whereas avoiding unfavourable costs by turning off as costs begin to dip and drop decrease. “That levelized worth is likely one of the issues that we predict is absolutely essential going ahead,” he stated.
“I feel what loads of fashions and planning eventualities miss after they have a look at one thing like LCOE—and so they’re taking a look at a single useful resource added into the system—is the way it suits throughout the system, and what does it do to the worth of the remainder of their portfolio?” Meeusen defined. “I name this: fascinated with the cannibalistic prices. If I have a look at an LCOE with a capability issue for a mixed cycle useful resource, and don’t contemplate how that may impression or enhance the curtailment of renewable power—no price renewable power—I don’t actually essentially see the true price of a few of these bigger, rigid turbines on the system. And, so, after we take into consideration that, we actually wish to ensure that what we’re overlaying and capturing is the true worth {that a} generator has in a portfolio, not simply as a standalone useful resource.”
Meeusen additionally prompt one other often-used metric may not be as sound as some folks imagine. “The put in price per megawatt might also have shortcomings, when it comes to, if I construct a 100-MW plant, will it give me 100 MW of useful resource adequacy capability or will it give me one thing lower than that?” he requested. “The engines don’t derate within the warmth. They don’t derate within the chilly,” Meeusen stated, noting that engines function and generate successfully in a number of the most excessive circumstances around the globe. Many different energy producing applied sciences can not say the identical factor.
“Once we take into consideration this when it comes to the prices you’re paying for technology, we’d like to consider how all these prices match collectively,” stated Meeusen. “Vitality, are we getting the levelized worth of power? And put in prices, are we getting the put in price per megawatt or the put in price for every megawatt of useful resource adequacy capability that I’m constructing and offering? And I feel these are actually essential parts after we try to steadiness everything of that complicated equation that utility planners and system planners need to undergo.”
