Strong wind does not remove the grid's constraints

If local demand and export capacity cannot absorb the available generation, some output may be curtailed. Orkney’s managed connections show how a network can admit generators while limiting their output at particular times.

Questions you could explore

  • How would storage or flexible demand change the constraint without making it disappear?
  • How do limited transmission capacity and system-balancing requirements create different reasons to curtail a turbine?

A solar cell's route from light to electricity

Shining sunlight onto a piece of silicon is only the first step in making solar power. When incoming photons knock electrons loose inside the semiconductor, an internal electric field built into the solar cell's layers must separate those charges and guide them into an external circuit before they simply recombine.
