dc.descriptionAs energy has been an important commodity requiring in almost every field. As accessible energy has quantitative constraints, efficient energy use has become critical. A major principle of utility-sector energy efficiency programs is that the energy they conserve reduces and balances the energy that would otherwise be delivered by the electricity grid or the natural gas infrastructure(Schumacher & Sathaye, 1999). Such saved kWh (electricity) or thermals (natural gas) are viable system resources because energy savings from customer programs can lower system demand enough to prevent the need for new supply infrastructure, such as generation plants, transmission lines, and distribution system upgradesen_US
dc.description.abstractThis study is aimed at examining the energy efficiency, energy intensity, environmental emissions reduction potential and energy security scenario of Hetauda Cement Industry Limited (HCIL) in Nepal. The research is being conducted with the objective of studying an existing benchmark for the energy intensity of the cement industry in Nepal and to examine the energy security risks for the limestone-based cement industries relying on imported energy. A study of the energy efficiency of the HCIL identifies that for the past five years specific power consumption has gradually increased from 223 kWh per ton to 295 kWh per ton of cement. The capacity utilization of the plant was below 50%. The plant's continuous operation over the last 36 years has reduced the efficiency of various plant equipment, increased breakdown time, increased production costs, and increased other indirect losses. Study suggests ways to optimize energy usage and reduce costs with lighting improvement with payback period of around 2 years, a gravel bed filter installation to emission control with payback of 3 years and waste heat recovery unit of 1.2 MW electricity capacity with payback of 14 yearsen_US
