Virtually every grid requires an interconnection study before allowing any generator to interconnect. Because of the variable output of renewable energy plants, some jurisdictions mandate ramp rate limitations to help stabilize the grid. For example, in Puerto Rico new solar plants must have enough energy storage to. .
It is not necessary to co-locate energy storage with a solar plant to provide grid services to stabilize the grid (e.g. ancillary services). The main reason that you would co-locate the two systems. .
The third application is what most people think about when they hear solar + storage: the ability to deliver firm energy commitments during certain hours of the day (i.e. semi.

The average hydropower is 133 TWh/year (135.3 TWh in 2007). There is also a large potential in , and , as well as p.
[pdf] Renewable energy in Finland increased from 34% of the total final energy consumption (TFEC) in 2011 to 48% by the end of 2021, primarily driven by (38%), (6.1%), and (3.3%). In 2021, covered 53% of heating and cooling, 39% of electricity generation, and 20% of the transport sector. By 2020, this growth positioned Finland as h.
