Inditex founder Amancio Ortega's investment firm Pontegadea is pushing further into renewable energy, closing in on a deal with Repsol to buy a 49% stake in its wind farms and photovoltaic power plants in Spain, two sources familiar with the deal told Reuters. The Spanish fashion retail billionaire's potential acquisition would expand Pontegadea's investments in renewable energy. The Repsol renewable projects up for sale have a total capacity of about 600 megawatts and the transaction values them around 700 million euros ($747.18 million), sources said.
