What happened

Great Britain is braced to pay millions for backup electricity supplies to prevent a shortfall on Wednesday evening as the near-total solar eclipse is expected to wipe out solar power generation.

Why it matters

The government’s electricity grid operator is expected to make multimillion-pound payments to secure electricity at short notice before the moon blocks up to 95% of the sun over parts of the country, the most dramatic solar eclipse visible in Great Britain…

Common ground

Gas plants are among the generators that are expected to claim payments of more than four times the market price after the grid operator raised an official alarm that it expects there will not be adequate power generation on Wednesday evening.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
