Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the Registrant under any of the following provisions (see General Instruction A.2. below):

On July 9, 2015, PowerSecure Solar, LLC, (“PowerSecure Solar”), a Delaware limited liability company and a wholly-owned subsidiary of PowerSecure International, Inc., a Delaware corporation (the “Company”), entered into an Engineering, Procurement and Construction Agreements (the “EPC Contract”) with Georgia Power Company (the “Utility”). This EPC Contract relates to a large utility-scale solar distributed generation project (the “Solar Project”) that will be performed for the Utility for the benefit of the Utility’s customer (the “Utility Customer”). This Solar Project is expected to generate approximately $85 million in revenue to the Company. The Company currently expects to recognize approximately $4 million in revenue from this Solar Project in the fourth quarter of 2015 and $81 million in revenue from this Solar Project throughout 2016. The Company expects that this Solar Project, which is large in scale and carries significantly lower gross profit margins as a percentage of revenues compared to non-solar distributed generation projects, will be dilutive to its consolidated gross margins as a percentage of revenues, while being accretive to its net income and earnings per share.

The EPC Contract provides for customary covenants, representations, warranties and indemnities by PowerSecure Solar to the Utility. The EPC Contract also includes terms requiring PowerSecure Solar to provide performance guarantees and indemnification to the Utility under certain circumstances, as well as containing provisions requiring PowerSecure Solar to pay the Utility liquidated damages upon the occurrence of certain events, including certain delays in substantial completion and when the system is placed in service. The aggregate limit on PowerSecure Solar’s liability to the Utility for delay liquidated damages under the EPC Contract is approximately $34 million. PowerSecure Solar could have additional liability to the Utility for any breaches of its covenants, representations or warranties in addition to delay liquidated damages. The aggregate limit on PowerSecure Solar’s overall liability to the Utility under the EPC Contract is equal to the overall Solar Project price, which will be reduced to 40% of the overall project price after substantial completion. The EPC Contract also contains typical events of default, including material breaches of the EPC Contract after notice and cure periods and defaults relating to bonding and surety defaults.

The Solar Project is subject to certain conditions, including (i) the receipt of all required regulatory approvals by the state public utility commission, and (ii) the issuance of a notice to proceed by the Utility. The work on the Solar Project will not commence until the Utility issues a notice to proceed, after the Utility has received all required regulatory approvals form the state public service commission. The Utility is required under the EPC to exert commercially reasonable efforts to obtain the required regulatory approvals and to issue the notice to proceed promptly upon receipt of such approvals. If the Utility fails to issue a notice to proceed within 120 days of the effective date of the EPC Contract, then the EPC Contract may be terminated by either party without any further liability other than the Utility will be obligated to reimburse PowerSecure Solar the amount of actual cost reasonably incurred by PowerSecure Solar up to $225,000 plus any supplemental work authorized by the Utility. Under the EPC Contract, PowerSecure Solar provides a warranty for three years after substantial completion of the Solar Project.

If the Solar Project is not placed in service by December 31, 2016, due to the failure by PowerSecure Solar unrelated to a force majeure event, a delay caused by the Utility or other events beyond PowerSecure Solar’s control, then PowerSecure Solar would pay the Utility the amount of investment tax credit lost by the Utility on the Solar Project due to the delay.

On July 10, 2015, the Company issued a press release announcing that it has been awarded approximately $100 million of new distributed generation business, including the Solar Project awarded by the Utility under the EPC Contract discussed above in Item 1.01.
