Typical energies are many orders larger than e.g., power station generators.
The reconnection process associated with substorms produce characteristic signatures in the magnetic field and particle flow. A large part of the energy is eventually deposited into the polar ionosphere as particle precipitation followed by aurora. Norway mapped into the magnetosphere using the T96 field model at a given date. An X-ray auroral breakup mapped to the magnetosphere.
