Grangemouth refinery complex, one of the largest in the world sits on the river Forth only a few miles from Scotlands capital Edinburgh. For the third time in less than a year the plant was shut down, and giant soot filled flares of burning petrochemical product lit up the night sky for miles around.

Why? Another electrical failure from the local power station.

Its sad that such a major industry has not taken steps to ensure it has a secure mechanism to deliver electricity.
