Exhibit 99.2

Dear PowerSecure Teammates:

Today is one of the most exciting days in the history of PowerSecure!

We are announcing today (see press release attached) that we have reached a merger agreement for PowerSecure to become a wholly-owned subsidiary of Southern Company, one of the largest investor owned utilities (IOUs) in the United States, and one of the most respected utilities in the world.

This is great news for us as the transaction will offer PowerSecure new opportunities and the benefits of a much stronger financial platform as part of Southern Company. In 2015, Southern Company reported earnings of $2.4 billion, or $2.60 per share, and has a significant balance sheet. Customers and potential customers will now see this balance sheet standing behind PowerSecure. And Southern Company’s constructive approach to other IOUs and utilities will enable PowerSecure to continue serving our utility partners with the resources and expertise of Southern Company supporting us.

There is also tremendous synergy between the corporate cultures of Southern Company and PowerSecure. Both companies are centered on core values of integrity and customer service. Our culture at PowerSecure has been vital to our success and this culture will continue to be nurtured within Southern Company. One of the reasons Southern Company has such a strong culture is because of their leadership team, which is among the very best in the industry. Several of PowerSecure’s leaders (including me) started our careers at Southern Company or have worked closely with them as a customer and we have personal experience with their outstanding team.

YOUR hard work and success are responsible for PowerSecure reaching this milestone. Because of the value we have all have delivered to customers over the past 15 years, Southern Company is paying more than $400 million to acquire PowerSecure. This represents an approximately 80% premium over the current share price of PowerSecure and is an affirmation of what we have accomplished together.

As exciting as today is, it is just the beginning of an even more exciting future for PowerSecure. Southern Company understands the importance of distributed infrastructure for the energy industry and believes that this transaction will position the combined company to compete effectively in that space.

I will host a call for our team leaders later this evening to discuss how we plan to respond to any questions from customers, and we will be scheduling town hall sessions across the company to celebrate and to answer any questions you have. We expect the acquisition to be completed by the end of June. Until the acquisition is completed, PowerSecure will continue to operate as an independent company. Today’s announcement may lead to questions from the press and financial community. If you are contacted, please do not respond to these inquires and forward them directly to John Bluth at 919-453-2103.

On a day-to-day basis, it is business-as-usual for PowerSecure. We will stay focused on serving our customers with world-class solutions and superior customer service.

Thank you for all you have done to help PowerSecure achieve the success that Southern Company has validated today!

Sidney Hinton

President and CEO

PowerSecure International (NYSE: POWR)
