The Role of Existing Power Plants

 As the article mentions, existing power plants can play a role in easing the grid integration of VRE. However, it is essential to note that not all power plants are created equal. Some power plants, such as gas turbines, are more flexible than others and can ramp up or down quickly to compensate for fluctuations in VRE output. Other power plants, such as coal plants, are less flexible and may need to be able to adapt more quickly to the integration of VRE.

Whether or not to keep existing power plants online will depend on several factors, including the cost of the plant, its flexibility, and its environmental impact. In some cases, retiring existing power plants and replacing them with new, more flexible VRE projects may be more cost-effective. In other cases, it may be more economical to keep existing power plants online and use them to help integrate VRE.

The decision to integrate VRE into the grid is complex, and there is no single "right" answer. The best solution will vary depending on the specific circumstances of each grid. However, by taking the steps outlined in this article, governments can help to make the grid more compatible with VRE and accelerate the transition to a clean energy future.
