[font size="+1"]Wind and reliability: baseload power.[/font]
Former Federal Energy Regulatory Commission (FERC) Chairman Jon Wellinghoff has stated that baseload capacity is going to become an anachronism and that no new nuclear or coal plants may ever be needed in the United States.[1] This fact sheet explains why baseload power is an obsolete concept in a world where a variety of other resources can provide the three commodities needed by the power system energy, capacity, and flexibility at competitive prices. A combination of a large amount of renewable energy, combined with flexible natural gas plants and demand-response and efficiency, can ensure that our electric system has sufficient energy, capacity, and flexibility, and operates cost-effectively and reliably.

Reliable and cost-effective operation of the electric grid requires a mixture of three types of resources: energy (electricity), capacity (ability to generate electricity at a certain point in time), and flexibility (ability to "turn up" or "turn down" electricity generation as needed). Each of the various types of power plants that generate electricity nuclear, coal, gas, hydroelectric, wind and others may specialize in providing one or two of these attributes, but no power plant excels at providing all three.
"Baseload" plants, a term typically applied to nuclear or coal-fired power plants, provide energy and some capacity. Interestingly, other types of power plants can provide these resources, often at costs competitive with baseload plants. Wind plants can produce energy just as well or better than nuclear or coal plants, while natural gas plants can provide capacity at lower cost than nuclear or coal plants. Thus, despite claims to the contrary, there is no inherent need for baseload power.
Moreover, baseload power plants provide almost zero flexibility, even though flexibility is a power system need that is just as essential as energy or capacity. In contrast, wind energy makes very valuable contributions towards ensuring that the grid has the right mixture of energy, capacity, and flexibility.
