In March, ER Project realized the project of reactive energy compensation for the company Trasnportbeton - Kiseljak. The project included consumption analysis, calculation and selection of equipment, including the production and commissioning of two cabinets of automatic compensation (170kVAr Quarry and 200kVAr Concrete Batching Plant). Based on previous spendings and future investments, the estimated savings after the project is around 14,400 KM per year, while the return on investment is less than a year. We thank our partner Demel and Transportbeton for their trust.
