Terra Firma,the multi billion pound Private Equity firm has continued its Renewable Energy Asset Buying Spree spending a monstrous 641 millino Euros to buy Rete Rinnovabile a solar plant owner and operator in Italy.The acquired company is a susdiary of Italian market grid operator Terna and owns around 150 MW solar capacity in Italy which witnessed a massive solar boom in 2010.The acquisition values 1 MW at 4.5 Euros which would be considered not an expensive price given the large returns available for Italian solar power assets which gets a generous government mandated feed in tariff.The solar power plants are well located near distribution end points which is not a surprise since the company was a subsidiary of the grid power operator.
