Low-Carbon Generation Mix The generation resulting from the technology mix defined in the low-carbon scenario is shown in table 6.7, and compared to the reference scenario. Over time, the alternative scenario develops a more diverse portfolio of technologies than the reference scenario. Grid-connected technologies still include a substantial amount of gas, but with a larger proportion of CCGT, because their greater efficiency results in a lower cost of generation than SCGT at projected higher gas prices, and somewhat lower emissions.
