Installed capacity of operating assets, not electricity generated — a GW of solar and a GW of gas do not produce the same energy in a year.
Capacity built per year
123.4 GW operating across 4,065 tracked assets, 9.3 GW under construction · last five years up 6% on the five before.
Built from assets operating today, by commissioning year — plants that closed before now are not in the data, so early years show only what survived. The forward bars are capacity physically under construction, not a forecast. A further 5.5 GW is under construction with no stated completion year. 7.9 GW of operating capacity has no commissioning year and sits outside the curve. 1 asset has an announced retirement date; closures are not otherwise tracked, so no net-capacity line is drawn.
85% of Spain’s tracked capacity has an owner recorded.
