Rolls-Royce has provided the Alajuela textile company Proquinal with the technology it needs to successfully implement an integrated energy system in Costa Rica. The system includes both battery storage and solar cell systems on site.
Two 40-foot Rolls-Royce MTU battery containers with a total storage capacity of 4275 kWh and a capacity of 1500 kVA will be used to meet peak electricity demand, increase the company’s own use of solar energy and alleviate pressure on the public network. Solar Panel Swissol has installed 690 photovoltaic panels with a capacity of 255 kWp in Proquinal’s covered parking lots and connected to battery enclosures to support the system. By producing electricity without CO2, they help prevent more than 285 tons of CO2 emissions per year compared to traditional electricity generation. Costa Rica has set a goal of becoming carbon neutral by 2050.
MTU EnergyPack equipment is primarily charged from the grid at night, during favorable electricity tariff periods, and in the evening. The stored energy is used for Proquinal Costa Rica’s textile production process during two peak hours, morning and night, when energy costs are highest. Because electricity is 4.5 times more expensive during peak hours than at night, the new energy system will allow the company to achieve savings of approximately $ 41,000 per month, which will recover the investment in 4.3 years.
