For decades, regional power grid operators relied almost exclusively on fossil-fuel peaker plants to maintain system stability during unexpected surges in electricity demand. Recently, however, municipal utility commissions began mandating the integration of large-scale lithium-iron battery storage systems to absorb surplus solar power. Critics contend that battery degradation over time makes these systems financially unsustainable for long-term grid support. Nevertheless, newly developed predictive thermal management software significantly extends battery lifespan, demonstrating that battery storage remains a cost-effective alternative to fossil-fuel generation.
In the argument presented above, which of the following best describes the role played by the bolded portion?
- It describes a historical practice that provides contextual background for the current regulatory transition and subsequent debate.Cevap
- BIt is a premise offered directly to support the author's main conclusion regarding the cost-effectiveness of battery storage.
- CIt presents the primary conclusion that the overall argument is structured to establish.
- DIt introduces a counterargument raised by critics to challenge the viability of municipal utility mandates.
- EIt serves as an intermediate conclusion derived from evidence about battery management software.
