ATLANTA, GA – September 16, 2005 – Prenova announced today that it has engaged in a three-year contract with a major U.S. wireless carrier. Prenova will provide Bill Data Management, Rate and Tariff Optimization, Price Risk Management, and PreVue®. The customer selected Prenova over a number of suppliers evaluated because of Prenova’s unique energy management capabilities and value proposition. Prenova’s domain expertise, strong technology platform, and cost effective solution helped drive the customer’s decision to collaborate with Prenova.

Through its Bill Data Management solution, Prenova performs a series of powerful proprietary processes on the customer’s utility bill data to identify bill errors (including rate and tariff reviews) and anomalies, which Prenova investigates and resolves. Prenova then ensures that these corrections are sustained in all subsequent bills. The corrected billing information is then available through Prenova’s web-based digital dashboard tool PreVue®. Prenova's PreVue web application is the "window" through which the customer views, understands, and manages the impact of energy performance. PreVue provides standard views of facility and portfolio performance for usage and cost, and offers quick links to all services rendered by Prenova. All customer analytics are accessed through PreVue.

Prenova will also provide the customer its Rate and Tariff Optimization and Price Risk Management solutions in regulated and deregulated energy markets, respectively. Through the Rate and Tariff Optimization solution, Prenova identifies the best possible regulated commodity rate for each relevant site in the customer’s portfolio. Prenova will provide the customer its Price Risk Management solution in deregulated energy markets. Prenova’s Price Risk Management solution addresses the optimization of cost and risk in procuring electric and gas energy for the enterprise. Price Risk Management includes the continuous review of market conditions to assess and determine both the potential near-term and future impact on financial outlooks these market changes create for the customer’s energy supply portfolio in terms of potential savings or risks. Price discovery is a critical part of this solution. Prenova then develops strategies and plans for managing price and risk, recommends specific actions to the customer, executes the agreed actions, and performs Quality Assurance to ensure that changes are accurately implemented.
