Ontario FIT program, and other commercially oriented incentives. Renewable energy sources in Chile benefit from an RPS program. Any adverse change to, or the elimination of, these incentives could have a material adverse effect on our business and our future growth prospects.

If any of the laws or governmental regulations or policies that support renewable energy change, or if we are subject to new and burdensome laws or regulations, such changes may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Maintenance, expansion and refurbishment of renewable energy facilities involve significant risks that could result in unplanned power outages or reduced output.

Our facilities may require periodic upgrading and improvement. Any unexpected operational or mechanical failure, including failure associated with breakdowns and forced outages, and any decreased operational or management performance, could reduce our facilities’ generating capacity below expected levels, reducing our revenues and jeopardizing our ability to pay dividends to holders of our Class A common stock at forecasted levels or at all. Incomplete performance by SunEdison or third parties under O&M agreements may increase the risks of operational or mechanical failure of our facilities. Degradation of the performance of our renewable energy facilities provided for in the related PPAs may also reduce our revenues. Unanticipated capital expenditures associated with maintaining, upgrading or repairing our facilities may also reduce profitability.

We may also choose to refurbish or upgrade our facilities based on our assessment that such activity will provide adequate financial returns and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs, timing, available financing and future power prices. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Moreover, spare parts for wind turbines and solar facilities and key pieces of equipment may be hard to acquire or unavailable to us. Sources of some significant spare parts and other equipment are located outside of North America and the other jurisdictions in which we operate. If we were to experience a shortage of or inability to acquire critical spare parts we could incur significant delays in returning facilities to full operation, which could negatively impact our business financial condition, results of operations and cash flows.

Our KWP II wind power plant is required under its PPA to install and maintain a battery energy storage system, the manufacturer of which is in bankruptcy and no longer supplies batteries to any customers. If we are unable to source acceptable replacement batteries, this could result in a default under, or termination of, KWP II’s PPA.

Our Kaheawa Wind Power II (“KWP II”) wind power plant is required under its PPA to install and maintain a battery energy storage system (“BESS”). The manufacturer of the BESS is in bankruptcy and is no longer providing replacement batteries and other components for the BESS. We are sourcing replacement batteries from a new supplier, but such replacement batteries may not be sufficient for the system to operate as designed or may not be available in the quantities or at an economical price. Our Kahuku wind power plant had a similar BESS that was required to be operated under its PPA, but the BESS was destroyed in a fire. The facility installed a D-Var system as a replacement for the BESS under the Kahuku facility PPA, which has been operating as designed. If the BESS system at KWP II was damaged or could no longer operate, a D-Var could not be used at the KWP II facility as a replacement to the BESS due to technical constraints, and another replacement system may not be compatible or available at a price that would allow the facility to operate economically. Failure to maintain the battery system constitutes a default under KWP II’s PPA and could result in the termination of KWP II’s PPA, which could negatively impact our business financial condition, results of operations and cash flows.

Certain of the wind power plants use equipment originally produced and supplied by Clipper Windpower, LLC, or its affiliates (“Clipper”) which no longer manufactures, warrants or services the wind turbines it produced. If Clipper equipment experiences defects in the future, we may not be able to obtain replacement components and will need to self-fund the correction or replacement of such equipment.

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.
