MADRID, Oct 31 (Reuters) - Spain's 1,000 megawatt Vandellos II nuclear power station was working at about 30 percent of capacity on Friday morning after being reconnected to the grid on Thursday afternoon, technicians said.
The Iberdrola-owned plant near the northeastern port of Tarragona had been halted since one of its generators caught fire on Aug. 24.
That leaves six of Spain's eight nuclear plants working at part or full capacity.
Between them, Spain's nuclear plants were generating 4,665 MW by 0820 GMT, or 12.1 percent of demand, according to national grid operator REE. That compares to about 7,300 MW when all are working normally.
The 1,000 MW Asco II nuclear plant has halted for refuelling, and the 1,000 MW Cofrentes plant has been off line for a week for maintenance work.
Increases in supply of nuclear power help to moderate prompt electricity prices
