Flexible power supply: Will it be coal or gas-fired plants?
Oct 30: Coal fired power plants can be made more flexible either by combining solar energy with coal-fired generation, or cofiring natural gas with coal. 8Both techniques are already used globally on a commercial basis, although deployment levels are currently low. 8However, under the appropriate conditions, both show potential for application to some existing and new-build power plants but both technologies have their limitations. 8A solar-based project will only make sense in locations that receive consistently high solar radiation. Similarly, cofiring with natural gas will only be possible where there is a reliable, affordable supply of gas available. 8Increasingly a competitive marketplace means that coal plants will now be forced to operate on a much more flexible basis. 8Regular start-stops, load following, and low load operation have increasingly become the norm.
