Many industries have evergy efficiencies, which present opportunites that can be addressed.
So a guy walks into a chemical plant and notices that they are heating a huge tank of water. He asks the plant operator “Why are you heating this water?” The plant operator replies “that keeps the water from freezing, which would cause a lot of trouble.” So the first guy asks the plant operator, “OK, but why are you heating the water in July?
That’s actually a true anecdote, and shows why behaviors and practices are such an important part of addressing energy efficiency. Many industries have such inefficiencies, which have simply become part of the operating routine. Why aren’t these opportunities being addressed?
One challenge in that many manufacturers don’t have good transparency into how and where they use electric and thermal energy. Competitive businesses today have clear KPI for quality, productivity and throughput. But some of the largest energy hogs are often buried in support processes such as electricity, compressed air, steam, water, or industrial gases - which are largely measured on their availability.
Even companies which do focus on energy can lack the technical expertise to understand what improvements can be made, or are unable to quantify the bottom line impact of such recommendations to their management.
ABB’s approach is to take customers on a journey from on-site assessments to implementation, so real bottom line results are realized. Over ten years of experience in many industries, ABB has learned that energy savings of 5 to 35 percent can often be created. This can make a significant contribution to competitiveness and environmental performance, especially in industries where energy is a large part of the cost structure.
Articulating a clear business case for energy efficiency improvement projects is often the sticking point to implementation. ABB gets over this hurdle with a feasibility and master plan that identifies a manageable number of projects with clear financial returns and guaranteed performance, which can move opportunities from identification to realization.
