Peru: Peak Shaving


In 2009, delays in the construction of a cross-country gas pipeline, transmission, and distribution infrastructure, coupled with droughts that caused hydroelectric generation shortages, prompted Peru’s president to issue an emergency decree that allowed the state-owned electric utility company, Electroperú (ELP), to contract a temporary power generation solution.


The site, located in Trujillo, needed extensive work, including the removal of sand dunes and the construction of fuel storage tanks capable of providing 72 hours of fuel storage capacity operating in full load. Due to Peru’s progressive regulatory and commercial environment, extra attention was needed to obtain and execute all required permits, documentation, and special exemptions, while simultaneously constructing the power plant.


APR Energy designed, built, and commissioned a 60MW temporary power plant to help the Peruvian government alleviate its power supply constraints. Prior to the installation of the diesel power modules, our engineering and operations teams performed extensive civil works on the undeveloped site, including the installation of 13.8kV transformers, construction of 1.2 million liters of permanent fuel storage capacity, and a 138kV substation. The modular power technology was chosen to ensure that several units could be held in reserve as standby power, while the other units collectively delivered 60MW. This way, with the units running from 12 to 24 hours a day, we had the flexibility to perform periodic maintenance without affecting the total output.


APR Energy’s Trujillo site was awarded the title of one of the "World’s Best Power Plants" by Diesel & Gas Turbine Worldwide magazine. In 2011, APR signed a new 60MW contract to meet the changing needs of the customer, and moved the equipment nearly 1,600 kilometers south to Mollendo. Due to its location on a hillside, the site required removal of 20,000 cubic meters of earth to ensure a level area. In addition to the site preparation, APR Energy expedited the refurbishment of the existing 2 million liter fuel storage tanks and constructed a high voltage interconnection bay connected to the Red de Energía del Perú (REP) substation. APR Energy adhered to all environmental, emissions, and sound requirements for Peru’s stringent national Environmental Management Plan (PMA), in addition to establishing numerous health, education, and environmental programs in support of local community development.
