  Iberdrola SA said Tuesday that it has waived initially imposed conditions for the total acquisition of renewable-energy provider Infigen Energy. 


  The Spanish utility company said it is still committed to acquiring a stake of more than 50% in the company. 


  Iberdrola said on Monday that it had decided to increase its offer to 89 Australian cents (US$0.61) per security in cash, from AUD0.86 previously.
