资料简介

由于天然气的低成本供应,以及电网规模和幕后间歇式可再生能源发电的日益普及,美国电网正在迅速发展。电池存储和其他技术的创新和成本降低意味着这种变化的步伐可能会继续下去。这些变化引发了一场关于历史上被称为“基载”发电资源的需求的辩论,比如以煤为燃料的发电厂和核电厂。这些资源传统上是全天候运行的,持续以稳定的价格提供可靠的发电,并有助于提高电网的整体弹性。正如本报告所解释的,这些传统资源(包括以煤为燃料的发电)提供的属性在电网继续发展的过程中仍然是至关重要的。

The U.S. electricity grid is rapidly evolving due to the low-cost supply of natural gas and the increasing penetration of grid-scale and behind-the-meter intermittent renewable generation. Innovation and cost reductions in battery storage and other technologies mean that this pace of change is likely to continue. These changes have sparked a debate over the need for what have historically been referred to as “baseload” electricity generation resources, such as coal-fueled and nuclear power plants. These resources have traditionally operated around-the-clock, continually providing reliable electricity generation at a stable price, as well as contributing to overall grid resilience. As explained in this report, these traditional resources—including coal-fueled generation—provide attributes that will remain critical to the grid as it continues to evolve.
