Instead, top-up subsidies for existing capacity are based on a "reasonable profit" concept, set at 7.5% across useful plant life. This compares with double-digit profits previously attained.
Accordingly, capacity online before 2005 — 8.4GW, or 37% of the cumulative total — is stripped of all subsidies, breaking the Spanish state's promise to maintain incentives for 20 years.
That capacity will now receive the going market price only, as will all new capacity.
The decree, published this morning without negotiating with the sector, is "unfair" and "incomprehensible", said Luis Polo, director general of national wind association AEE.
Since the July law, and until the decree, operators carried on receiving the incentives that existed before before July 2013. Application of the new rules is now backdated to that month and operators must pay back the excess.
