Until recently, many organizations did not place a big focus on having an energy management program implemented for their operations. But the trend is changing rapidly, and energy management is becoming a necessity for cost efficient operations, to support highly available services and for becoming better environmental stewards.
Energy management is not a new topic at all. It has played -- and continues to play -- a significant role in many industries, particularly where the entire production cycle consumes huge amounts of energy from different sources. Whether it is a highly sophisticated plant operation or a managed service provider (MSP) providing IT services in a data center, improving the way energy is used in these facilities can lower operational costs, increase availability and reduce emissions.
However, the complexity involved in implementing such programs can be technically challenging. Yet at the same time, we all know that the benefits are huge with such implementations!
The Office of Energy Efficiency and Renewable Energy of the U.S. Department of Energy conducts technology showcases to encourage industry adoption of more energy efficient technologies and practices. By implementing best practices across industries, we can boost productivity and help achieve regional and national goals for energy conservation, the economy, and the environment.
Let’s take a look at an example. There was a case study conducted a while back for a large chemical plant in Texas. With proper energy management programs and tools, this plant was able to achieve significant energy cost savings. This surplus is leveraged throughout the company’s supply chain to provide value to their customers. This is tremendously huge! Overall results showed a 23% reduction in energy intensity (consumption per unit of production) that provided over $18.5M in cost savings and reduction of roughly 67000 tons of CO2 emissions.
The study cited several key elements to success that I think we should all make note of and consider as best practices in our programs:
-
An effective collaborative framework that included appropriate team members at all levels in project selection, evaluation and decision making
-
Involvement and financial support by senior management
-
Empowering the team members to carry out the energy management mission
-
Selection of the right tools and technologies to carry out the program.
Now, for another example, let me focus on those organizations with large data centers complaining about unplanned downtime in their data centers due to power and cooling issues. Why is this happening? The reason is very simple to begin with: no effective communications between facilities and IT teams. Which raises the question, how many IT organizations are using energy data points in their Change Management process today?
In addition, the latest technology trends -- such as dense form factor servers and virtualization technologies -- have increased the rack density. This increase in rack density demands more power and cooling at the rack level. With an implementation of a virtualization project within a data center, the number of racks of physical servers may be reduced, but in this much smaller area now dedicated to virtualized servers, the power and cooling requirements are much higher.
Is adding more cooling units the solution to this problem? It may or may not be. Air flow dynamics within a datacenter happens to be a complicated science. Not only that, but adding cooling units will increase your cost of operations, for sure. Are these facilities devices monitored efficiently for different variables that can be polled from these units? Advanced alerting techniques such as “time over threshold” and “deviation from normal,” etc., can be used to identify the failure states before they occur.
It’s probably becoming clear in my various examples that energy management is a continuous process that needs to be in place for operations to maintain high availability, thereby avoiding violation of SLAs to customers and potential revenue loss. An added benefit of implementing an energy management program is the cost savings. Best practices have generally said to think about keeping data centers at a particular operating temperature as per recommended standards. But, if we take a different approach in which the heat generated within a data center and heat removed from the data center can be identified and kept constant using technology, then this will result in automated cost savings related to energy.
There are so many important reasons why energy management should be a top priority for organizations of all sizes, both in IT and in other industries, whether relying on cloud computing technology or resources in local data centers. Energy management can help to ensure high levels of availability for the services offered to users and customers, while reducing overall operational costs and greenhouse gas emissions.
Much more to come on this topic in a future post…
