"The price (of turbines) could clearly come down. In time of excess demand, the price of the machine itself has gone up 20 percent," director for Spanish power company Endesa's renewable energy division Fernando Ferrando said on Monday.

"I think the trend will be for cheaper machines," he said.

Acciona Energia and Iberdrola Renovables also called fow lower turbine prices at the 2009 Wind Energy Conference.

While finance for projects in the sector remains tight due to the credit crisis, companies await a new government regulatory framework that will set down guidelines on the rate of installation of wind farms and probably cut subsidies.

The credit crisis has fuelled a sharp decline in the number of financial institutions prepared to participate in project finance to fund wind energy deals.

"There are only about 7 or 8 institutions left. The local savings banks and the international banks have pulled out. There are less of us amongst whom to spread the load and risks are building up on our balance sheets," said Jesus Losa, director for energy, oil and gas at La Caixa, Spain's largest savings bank.

Prices, margins and the financial costs of wind energy projects have all increased because of this, he said. (Writing by Judy MacInnes; Editing by Dan Lalor)
