we conduct our business experience high rates of inflation, thereby increasing our operating costs in those countries, we may not be able to generate sufficient revenues to offset the effects of inflation, which could materially and adversely affect our business, financial condition, results of operations and cash flows.

A material drop in the retail price of utility-generated electricity or electricity from other sources could increase competition for new PPAs, limiting our ability to attract new customers and adversely affecting our growth.

Decreases in the retail prices of electricity supplied by utilities or other clean energy sources would harm our ability to offer competitive pricing and could harm our ability to sign PPAs with new customers. The price of electricity from utilities could decrease for a number of reasons, including:

the construction of a significant number of new power generation plants, including nuclear, coal, natural gas or renewable energy facilities;
the construction of additional electric transmission and distribution lines;
a reduction in the price of natural gas, including as a result of new drilling techniques or a relaxation of associated regulatory standards;
energy conservation technologies and public initiatives to reduce electricity consumption; and
the development of new clean energy technologies that provide less expensive energy.

A shift in the timing of peak rates for utility-supplied electricity to a time of day when solar energy generation is less efficient could make solar energy less competitive and reduce demand. If the retail price of energy available from utilities were to decrease, we would be at a competitive disadvantage in negotiating new PPAs and therefore we may be unable to attract new customers and our growth would be limited.

We may not be able to replace expiring PPAs with contracts on similar terms. If we are unable to replace an expired distributed generation PPA with an acceptable new contract, we may be required to remove the renewable energy facility from the site or, alternatively, we may sell the assets to the site host.

We may not be able to replace an expiring PPA with a contract on equivalent terms and conditions, including at prices that permit operation of the related facility on a profitable basis. If we are unable to replace an expiring PPA with an acceptable new revenue contract, the affected site may temporarily or permanently cease operations. In the case of a distributed generation solar facility that ceases operations, the PPA terms generally require that we remove the assets, including fixing or reimbursing the site owner for any damages caused by the assets or the removal of such assets. The cost of removing a significant number of distributed generation solar facilities could be material. Alternatively, we may agree to sell the assets to the site owner, but the terms and conditions, including price, that we would receive in any sale, and the sale price may not be sufficient to replace the revenue previously generated by the solar generation facility.

Our renewable energy facilities are exposed to curtailment risks, which may reduce the return to us on those investments and adversely impact our business, financial condition, and results of operations.

Certain of our renewable energy facilities’ generation of electricity may be curtailed without compensation due to transmission limitations or limitations on the electricity grid’s ability to accommodate intermittent electricity generating sources, reducing our revenues and impairing our ability to capitalize fully on a particular assets potential.

For example, our Stetson and Rollins wind power plants have experienced significant curtailment starting in February 2012 due to a combination of construction on the Maine Power Reliability Project (“MPRP”) a large transmission upgrade project affecting generation and transmission throughout Maine and adjoining areas, and transmission export limits at the Keene Road interface. These wind power plants in the aggregate have had curtailment of 40 GWh for 2015 and averaged 58 GWh in 2014 and 2013, respectively, attributable in the aggregate to the MPRP construction and the Keene Road interface limits. The elements of the MPRP that affect Stetson and Rollins were completed in 2015. We are also currently pursuing several different solutions that may help to eliminate the Keene Road issue.

We are also experiencing curtailment with respect to other of our solar and wind power plants. Solutions to ameliorate or eliminate curtailment with respect to our power plants, including the Keene Road and other curtailment issues, may not be available or may not be effective or may be cost prohibitive to undertake and implement. Curtailment at levels above our expectations could have a material adverse effect on our business, financial condition and results of operations and cash flows and our ability to pay dividends to holders of our Class A common stock.
