The digital power plant of the future | McKinsey
Power-plant digital transformations face common pitfalls. Thermal generation still dominates the global fuel mix, with coal and gas making up 62 percent and representing 16 petawatt-hours (PWh) today. Our research shows coal and gas contribution to the fuel mix will stay constant until 2030, after which it will decrease toward 2050 (Exhibit 1).Web
