Exhibit 99.1

PowerSecure Enhances Focus on Data Center and Hospital Markets,

Introduces New PowerBlock^TM Mission Critical Power Systems

Wake Forest, N.C. — January 23, 2012 — PowerSecure International, Inc. (Nasdaq: POWR) today announced it has expanded and enhanced its strategy to serve customers in the large and growing Data Center and Hospital markets with mission critical power systems. The Company’s sharpened focus includes the hiring of two industry executives to lead the Company’s sales and marketing efforts in each of the Data Center and Hospital categories. Additionally, the Company has introduced a new industry-leading version of its PowerBlock^TM proprietary generator system that runs on a combination of natural gas and diesel fuel, is Tier 4 Interim emissions compliant, and improves redundancy. The Company’s decision to enhance its resources and introduce new technology for these markets comes on the heels of strong success with dozens of multi-million dollar installations of Interactive Distributed Generation^® (IDG^®) Systems for data center and hospital facilities over the last several years.

PowerSecure’s newest version of its PowerBlock proprietary generator system is fueled by a precision blend of natural gas and diesel fuel (“bi-fuel”) and has a powerful Tier 4 Interim engine — all in a factory-certified package. The engine’s bi-fuel capability is built directly into the technology, so there is no retrofit required to enable the use of natural gas. The new technology enables a blend of up to 70% natural gas to be utilized, and provides significant fuel cost savings, high power density, and advanced SCR technology to meet stringent, Tier 4 Interim EPA and CARB emissions regulations. PowerSecure’s PowerBlock system is engineered to maximize redundancy and dependability, and provide a highly efficient solution for mission critical Data Center and Hospital operations.

Sidney Hinton, CEO of PowerSecure, said, “We are excited about our enhanced focus and the new PowerBlock technology we are introducing to serve the needs of the Data Center and Hospital markets. Our new PowerBlock is designed with industry-leading bi-fuel capabilities to capitalize on the low cost of natural gas, in a factory certified Tier 4 Interim compliant package. The two executives we hired to lead our efforts are trusted industry pros — with long, successful track records of serving Data Center and Hospital customers — and we are excited with the focus and expertise they will bring to customers in these large and growing markets.”
