The Cohocton, Kahuku, Sheffield, and Steel Winds I and II wind power plants operate 92 Liberty turbines, with a combined nameplate capacity of 230.0 MW, supplied by Clipper. Since initial deployment, Clipper has announced and remediated various defects affecting the Liberty turbines deployed by us and by other customers, which resulted in prolonged downtime for turbines at various facilities. Moreover, Clipper no longer manufactures, warrants or services the Liberty turbines or other wind equipment it produced.

Beginning in 2012, we engaged in a number of litigation and arbitration proceedings with Clipper concerning the performance of the Liberty turbines. On February 12, 2013, all such disputes were settled pursuant to a Settlement, Release and Operation and Maintenance Transition Agreement among certain of our and Clipper entities (the “Settlement Agreement”). Pursuant to the Settlement Agreement, we have, among other things, released Clipper of all of its warranty obligations with respect to the equipment supplied by Clipper, and the obligations under the related operation and maintenance contracts, and we have been granted by Clipper a non-exclusive, royalty-free, perpetual, irrevocable license to make, improve and modify any equipment supplied by Clipper and to create derivative works from such equipment.

As a result, if Clipper equipment experiences defects in the future, we will not have the benefit of a manufacturer’s warranty on such original equipment, may not be able to obtain replacement components and will need to self-fund the correction or replacement of such equipment, which could negatively impact our business financial condition, results of operations and cash flows.

Developers of renewable energy facilities depend on a limited number of suppliers of solar panels, inverters, module turbines, towers and other system components and turbines and other equipment associated with wind power plants. Any shortage, delay or component price change from these suppliers could result in construction or installation delays, which could affect the number of renewable energy facilities we are able to acquire in the future.

There have been periods of industry-wide shortage of key components, including solar panels and wind turbines, in times of rapid industry growth. The manufacturing infrastructure for some of these components has a long lead time, requires significant capital investment and relies on the continued availability of key commodity materials, potentially resulting in an inability to meet demand for these components. In addition, the United States government has imposed tariffs on solar cells manufactured in China. Based on determinations by the United States government, the applicable anti-dumping tariff rates range from approximately 8% to 239%. To the extent that United States market participants experience harm from Chinese pricing practices, an additional tariff of approximately 15%-16% will be applied. If SunEdison or other unaffiliated third parties purchase solar panels containing cells manufactured in China, our purchase price for renewable energy facilities would reflect the tariff penalties mentioned above. A shortage of key commodity materials could also lead to a reduction in the number of renewable energy facilities that we may have the opportunity to acquire in the future, or delay or increase the costs of acquisitions. The risks discussed above under “The SunEdison Bankruptcy may adversely affect our relationships with current or potential counterparties” may be increased by our dependence on a limited number of suppliers.

We may incur unexpected expenses if the suppliers of components in our renewable energy facilities default in their warranty obligations.

The solar panels, inverters, modules and other system components utilized in our solar generation facilities are generally covered by manufacturers’ warranties, which typically range from 5 to 20 years. When purchasing wind turbines, the purchaser will enter into warranty agreements with the manufacturer which typically expire within two to five years after the turbine delivery date. In the event any such components fail to operate as required, we may be able to make a claim against the applicable warranty to cover all or a portion of the expense associated with the faulty component. However, these suppliers could cease operations and no longer honor the warranties, which would leave us to cover the expense associated with the faulty component. For example, a portion of our solar power plants utilize modules made by SunEdison and certain of its affiliates that are debtors in the SunEdison Bankruptcy. Our business, financial condition, results of operations and cash flows could be materially adversely affected if we cannot make claims under warranties covering our renewable energy facilities.

We are subject to environmental, health and safety laws and regulations and related compliance expenditures and liabilities.

Our assets are subject to numerous and significant federal, state, local and foreign laws, and other requirements governing or relating to the environment. Our facilities could experience incidents, malfunctions and other unplanned events, such as spills of hazardous materials that may result in personal injury, penalties and property damage. In addition, certain environmental laws may result in liability, regardless of fault, concerning contamination at a range of properties, including properties currently or formerly owned, leased or operated by us and properties where we disposed of, or arranged for disposal of, waste and other hazardous materials. As such, the operation of our facilities carries an inherent risk of environmental liabilities, and may result in our involvement from time to time in administrative and judicial proceedings relating to such
