July 9, 2012. HSBC Holdings Plc, Europe's largest bank, is advising on potential acquisitions of renewable-energy companies as an oversupply of equipment in the wind and solar industries drives down prices. The renewable- energy industry is consolidating as cuts to subsidies in countries including Germany and Spain slow growth. Industrial and energy companies are seeking to shift from developed, mature markets to emerging regions that are growing, including Saudi Arabia, South America and Asia. Prices for solar panels fell 45 percent in the past year, and wind turbine prices dropped 6 percent in the 12 months through the end of the second quarter. HSBC is also working on "equity raisings" for some clients considering expanding their portfolios and is evaluating financing opportunities for wind and solar projects, especially in emerging markets.
