OSLO, Jan 17 (Reuters) - Norway's $1.3 trillion sovereign wealth fund, the world's largest, said on Tuesday it had agreed to buy a 49% stake in Iberdrola's 1.3 gigawatt (GW) portfolio of Spanish solar plants and onshore wind farms for 600 million euros ($650 million).
Iberdrola (IBE.MC) will remain co-owner and operator of the portfolio, Norges Bank Investment Management (NBIM), the operator of the Norwegian fund, said in a statement.
"The portfolio comprises seven solar plant projects and five onshore wind projects with an installed capacity of 1265 MW, equivalent to the annual electricity consumption of 700,000 Spanish households," NBIM said.
Solar plants make up 80% of the portfolio, while onshore wind accounts for the remaining 20%.
It recently sold a 49% stake in an offshore wind farm in Germany for 700 million euros.
