This resulted in the first off-grid solution of its kind in the Americas for Rolls-Royce Power Systems, manufacturer of the mtu products. Constructed in just a few short months, the facility went online in late 2018 and has enjoyed continuous, uninterrupted power ever since. “There were multiple factors beyond reliability that needed to be considered when deciding on power solutions for this facility,” said Daniel Salazar, President, Electriz. “Cost-effective efficiency at that altitude, while also taking environmental factors into consideration, is difficult. However we knew that by working with Rolls-Royce, we could get it done.”
“We have a vision at our company to be the most recognized and most preferred pork company in Mexico,” said Rafael Patino, Director of Environment & Energy, Granjas Carroll. “That is a big challenge and sustainability is one of our pillars of production, so our project came with very demanding specifications.” The four gas units used at the facility are 20-cylinder Series 4000 natural gas systems delivering altogether 7.7 MW of electrical power, capable of handling the pork processing facility’s altitude demands with the lowest derating, ensuring maximum power availability at the site. In a second phase, it is planned to use the heat out of the exhaust gas, the oil cooler and the mixture cooler to efficiently produce steam and hot water, which can then be used in the production processes.
A single 16-cylinder Series 4000 diesel generator system with an electrical output of 2 MW is tasked with absorbing greater load blocks than the natural gas units, offering long-term stability to the plant. The diesel unit will run continuously with loads as low as 10 percent to minimize fuel consumption, allowing the natural gas units to produce more energy. An mtu MCS master control panel integrates plant control and remote operation, and all systems run in isolation from the power grid, providing reliable, stable and efficient electrical power to the entire facility.
