  • Leveraged lease financing. We represented an institutional investor and its affiliates as equity investor in the leveraged lease financing to Pattern Energy Group's subsidiary, Hatchet Ridge Wind, LLC, the lessee of a 101.2 MW wind energy project located in Burney, California.

  • London offshore. We advised a Dutch contractor in a bid for the London Array offshore wind farm project, the largest offshore wind farm in the UK, consisting of 271 wind turbines intended to provide over 1000 MW of electricity to London.
  • Mexican wind farm. We represented Madrid-based Preneal SA and its affiliates on the sale of two wind power project companies, Energía Alterna Istmeña, S. de R.L. de C.V. and Energía Eólica Mareña, S.A. de C.V., to an equity consortium controlled by Macquarie.

The Otter Creek project is expected to produce approximately 200 megawatts of wind-powered electric generation and cost approximately $440 million to construct. The wind energy high-impact business program was enacted by the State of Illinois in 2009. The program enables wind energy developers to apply directly to the State for high-impact business designation, which enables the developer to qualify for a sales and use tax exemption on building materials purchased for the project.
  • US/Chinese joint venture. We represented Cielo Wind in its joint venture agreement with China's Shenyang Power Group on the development of a $1.5 billion, 600MW wind farm in Texas. This will be the first major US renewable project financed by Chinese banks and supplied with Chinese-made turbines.
