Comment Peak load assets (Score 3, Informative) 230
What *should* be scary but is being ignored by the larger public is how utilities are increasingly running "peak load" assets as if they were "base load" assets. To wit, combined-cycle turbine plants are not usually designed for continuous operation like this; they're designed to be brought online during peak load *only*. Base load assets like coal and nuclear carry the non-peak loads. The peak load assets are going to have much more intensive maintenance costs if they keep running them like this, leading to higher prices for consumers and the ugly potential for brownout/blackout when these peak load assets break down unexpectedly.
Disclosure: I'm a tech consultant working with TVA right now, and this info comes direct from people who run these assets. We *need* more base load assets like coal and nuclear, but government regulations are making that extremely difficult. Indeed, we're having to *shut down* coal plants due to new government regulations, further stressing an already-fragile national power infrastructure. Thank god we're *finally* building some new nuclear assets (TVA's Watts Bar Unit 2, and Georgia Power's Plant Vogtle Units 3 and 4) but we need to be doing this on a much larger scale to meet growing demands for power. Conservation will only take you so far; at some point -- a point I think we passed some years ago -- you must expand capacity to keep your system fault-tolerant.
