3 A B O U T S tellar Energy is a global leader in the design, construction, fabrication, installation, and servicing of a range of energy systems, including turbine inlet air chilling (TIAC) systems, district cooling plants, modular utility plants, and fielderected utility plants. Our experience spans more than 20 years and stretches across the globe, with offices in the United States, the Middle East & North Africa (MENA) region, and Asia. Customized We customize our solutions to meet our clients specific needs. By avoiding a one-size-fitsall approach, our systems more effectively help clients increase their profitability, enhance their power output, and cost-effectively cool S T E L L A R E N E R G Y their environments and industrial processes. While we often use a modular approach by prepackaging complete utility plants, we understand that each client and project is unique, and other methods may be more appropriate. Through detailed feasibility studies, we can determine the most process-, cost- and energy-efficient solution, whether it s modular, field-erected, or hybrid a combination of both. Flexible With an international team of direct-employed architects, engineers (of all disciplines, including process engineers), construction professionals, refrigeration specialists and operations and maintenance engineers, we can supply the industry s highest level of in-house, self-performed work. However we re flexible in our approach, whether it s providing turnkey design-build services, taking full accountability and responsibility for the entire project, or focusing specifically on one aspect of the project, working alongside other contractors, sub-contractors and specialists to meet our customers goals. Global We are truly global in our experience, expertise and relationships. From the United States, to the Middle East, North Africa and Asia, we know that each region operates differently, requiring a tailored approach. Through our network of suppliers and partners across the world, we can procure the most process and cost-efficient, high-quality solutions. stellar-energy.net
