The city of Copenhagen has a population of 600,000 and the Copenhagen Energy steam and hot water distribution systems go all the way back to 1925 and has grown over the years into one of the world’s largest district energy systems.
The Challenge A desire to become more efficient
A demand for high levels of efficiency, reliability, and optimization, as a direct result of the size and age of the Copenhagen district heating system, called for action. In addition, Copenhagen Energy continuously faces resource demanding tasks in the form of system renewals and expansions. In 2006 it looked at converting its steam based system into a hot water system.
The Solution Plan, design, optimize… TERMIS
TERMIS was chosen because of its fulfilling features as a planning, design, and optimization tool. Enabling the identification and quantification of strategies, TERMIS proved suitable for increasing efficiencies, reducing operating costs, and cutting emission. Copenhagen Energy employs TERMIS to provide decision-ready information that allows its entire staff to make the best possible decisions.
The Result Prepared for the future
Copenhagen Energy underlines the importance of the comprehensive functionality and user friendliness that TERMIS provides. With TERMIS, the Copenhagen Energy team has designed four milestone hydraulic and thermal model scenarios for the years 2010, ‘15, ‘20, and ‘30. However, as much as TERMIS is used for long term planning, the much is it used in the day-to-day design changes for expanding the network for new customers, maintenance and analysis of losses, analysis of equipment failures and break downs, and in analyzing bottlenecks.
Consumer Advantages Real-time benefits
The real-time functionality of TERMIS ensures that the consumers experience the highest possible reliability levels.
User Advantages Intuitive user interface
The very intuitive TERMIS user interface is an important attribute when it comes to training. The engineers at Copenhagen Energy were impressed by how little training they actually needed to master TERMIS on their own. Furthermore, even complex models are processed in a matter of seconds, providing fast calculation and simulation
results. All of which saves time.
The Future Implementing Temperature Optimization
The TERMIS Temperature Optimization module is in the process of being deployed and the initial conclusions advocate for significant cost savings as well as O&M benefits.
