Description
Early on in the development of electric power, its proponents and developers recognized the importance of economies of scale in power generation. If power could be distributed to a broader customer base, larger, centralized generation facilities could be built providing power at much lower costs. In turn, these lower costs would attract more customers, making even larger scale production possible. However, several factors limit the practical scale of central generation. Most obviously, the practical size of boilers, turbines, and other generating plant equipment is limited by the ability to manufacture and transport this equipment to a plant site. Over the last century, commercial power equipment has evolved such that practical generating station capacities have increased from 5 megawatts (MW)1 to several thousand megawatts. In the absence of other constraints, central plant size could continue to increase, at least in a modular fashion, by adding more and more units of similar design at a given site. There are other constraints, though, so that the practical size of central generating facilities may actually decline in the future. These constraints include fuel and resource supply at a given site, limits imposed by the natural environment for dissipating waste heat, transport and disposal of waste products, community environmental standards, reliability and security concerns, and the economics of power transmission.
