Over a tenth of Spain’s combined heat and power (CHP) capacity was idled in the first six months of this year, according to an industry trade group.

William Pentland, writing in Forbes, says the data comes from Acogen, and represents a total of 712 MW of CHP (about 12% of Spain’s total CHP capacity) stopped generating electricity during the first half of 2013.

In 2012, Spain raised taxes on all power generation by 7% while also reducing subsidies for renewable energy and CHP plants.

More recently, Spain imposed a $3.67 per MWh tax on natural gas, which is the primary fuel used by about 90% of Spain’s CHP plants.

Acogen is calling on the Spanish government to increase support for CHP or risk losing well over half of Spain’s more than 6 GW of CHP capacity by 2015.
