Wind and solar PV technologies have seen rapid cost reductions and can now provide electricity at or below the cost of traditional sources in a growing number of countries. This makes them more appealing for countries seeking to meet growing power demand and decarbonize their energy system at the same time.
Since variable renewable energy (VRE) technologies have certain unique properties, integrating them into power systems means understanding how they relate to other parts of the grid. The level of adaptation needed to effectively integrate VRE also changes as more low-carbon resources are built.
