< Back to all projects GENERADORA ELECTRICAL DEL NORTE LOCATION: Puerta Barrios, Guatemala SIZE & TECHNOLOGY: 5.8 MW Turbo Expander, Super Critical Propane, Cycle Evaporative Cooling DESIGN START: Fall 2012 IN SERVICE: Spring 2013 SCHEDULE: Construction Start Winter 2013, Construction Complete Summer 2013 FIRM ROLE: Engineering, Procurement Generadora Electrical Del Norte (Genor), a Guatemalan independent power producer, owned a 40 MW heavy fuel oil-fired reciprocating engine plant in Puerto Barrios, Guatemala. Recognizing the benefits of an improved plant heat rate, Genor under-took an analysis of ways to improve the output and efficiency of the Puerto Barrios facility. A number of options were analyzed to “combine cycle” the plant. The plant selected the Organic Rankine Cycle ORC-AT, as designed by Waldron. Waldron has an exclusive license agreement to design and construct the ORC-AT cycle. The cycle consists of a two-stage heat recovery system producing supercritical propane from exhaust waste heat. Energy in the propane is converted to shaft horsepower in a two-stage turbo expander coupled to a single generator via a common gearbox. Heat from exhausted propane is recuperated against propane prior to recycling to the superheater. Cooling for the cycle is via a bank of evaporative condensers. The plant will produce a net output of 4.0 MW for sale to the grid with the addition of no fuel input.

CONSULTING At Waldron, commissioning is a thoroughly mapped, step-by-step approach designed to explore the entire operating envelope of a facility and demonstrate the project’s key outcomes have been met. Because of our focused expertise in energy system engineering, we are able to remain constructively engaged throughout the process of testing, troubleshooting, and optimizing a facility’s performance. STEP-BY-STEP GUIDANCE PROJECT DEFINITION In-depth commissioning requires a thorough understanding of project goals. As with all of our services, the starting point is a detailed understanding of the specific financial, environmental and functional criteria established at the project outset. This knowledge informs the planning process. PLANNING There are three levels of planning: project level sequencing of system energization and functional testing with a facility, detailed step-by-step commissioning procedures for each system that guide the start-up and testing processes, and daily plans convened by Waldron’s commissioning manager on-site to coordinate all parties associated with or affected by the work. Much of our work is accomplished in operating facilities and requires a thorough understanding of the impacts commissioning will have on existing systems, as well as the ability to develop contingency plans. TESTING AND RESPONDING Commissioning is not a straight line from A to B: a thorough commissioning process is a daily encounter with the unexpected. Waldron’s commissioning teams excel at providing leadership and technical guidance to clients, contractors and operations teams when troubleshooting is necessary, and are capable of efficiently realigning resources to keep the process moving forward. Given the opportunity, we are not passive observers, but active contributors to the resolution of difficulties encountered. DOCUMENTATION Waldron provides daily reports of commissioning activities, as well as annotated procedures that document the step-by-step outcomes realized during the commissioning process. The result is a wealth of information for the facility owners and operators. It is possible to understand exactly what was tested, what worked and what didn’t and why, and how the deficiencies were resolved. The result is a clear roadmap for future operations.
