The government is planning to cap spiralling energy-sector debt, including ending a link between power tariffs and the consumer price index, and restricting pricing options for renewables firms.

Industry minister JoséManuel Soria says the moves would save the power sector €600m-800m ($822m-1.1bn) in annual regulated charges, which account for about half of Spanish electricity bills.

As part of the reform, renewables companies will be forced to choose between two pricing options, removing flexibility and potentially hurting future revenues.
