Abstract
Norwegian industry accounts for a substantial share of national energy
consumption. As electrification accelerates, industrial energy efficiency is critical to ease grid
stress and ensure reliable supply. This paper provides a comprehensive overview of energy
consumption in Norwegian industry and estimates the potential for energy efficiency
improvements. Utilizing data from 660 large-scale industrial facilities, this study focuses on the
nine most energy-intensive sectors, which represent 82% of Norway's industrial energy use.
Energy savings potential was calculated by comparing specific consumption against
references and prior studies. The analysis identifies a total energy saving potential of
approximately 8 TWh per year, corresponding to an 8.4% reduction in total industrial energy
use. These savings are primarily driven by improved processes and heat recovery, contributing
roughly 3 TWh each. The primary aluminum sector holds the largest single saving potential,
with substantial opportunities also identified in the Si/FeSi, gas processing, pulp and paper,
and food industries.
