Between 2015 and 2020, the improvement was even more significant at 15.63% (from 39% in 2015 to 55% in 2020).

Between 2015 and 2020, the improvement was even more significant at 15.63% (from 39% in 2015 to 55% in 2020). The continuous increase in overall energy efficiency was attributed to the older, less productive plants  shut-down, technical advances in the gas-fired plants, and a switch to combined-cycle plants. The gas-fired plants  efficiency will continue to improve over the next five years (2021-2025) by about 11% (from 55% in 2020 to 63% in 2027) (Figure 2).
The gas-fired plants' efficiency will continue to improve over the next five years (2021-2025) by about 11% (from 55% in 2020 to 63% in 2027) (Figure 2).
