Also another reason - a generation site may be curtailed, meaning that its output is restricted due to grid capacity limitations, and allowing it to export more energy onto the local power network may exceed safe operating parameters for the lines connecting the generation site to the grid.
Therefore in high wind, you would expect that in areas of dense generation, especially those with limited capacity interconnects to the rest of the grid, curtailment may be seen.
- rmccue 3y agoI could see this being the case for regional balancing, but presumably a 1GW generation site has a 1GW-capable link to the grid, otherwise that seems like overbuilt capacity? (nb of course you might overprovision it to some degree on the presumption that, say, only 70% of your generation is usable at any one time; I more mean the numbers like say 16%.)
