The largest ferroalloy manufacturer in Russia requested the RUSEFF experts to assess energy efficiency potential within the company.
During the energy assessment the experts discovered a number of energy saving opportunities and made the following recommendations:
Replace outdated air compressors with new higher efficiency models to reduce energy costs by around 40%.
Install variable speed drivers to regulate several motors resulting in reduced electricity consumption.
Reconstruct and insulate the hot water pipes.
Regulate the electric furnace with a control system to allow a more flexible operation further reducing energy costs.
The proposed investment of USD 1.0 million will result in annual savings of USD 243 000, a payback period of 3.5 years and an overall return on investment in terms of energy savings of 24.7%.
