TERMIS Provides District Heating for 0.5 Million Copenhageners

Copenhagen Energy, owner and operator of one of the largest steam and hot water based district heating systems in the world, has used TERMIS for more than 10 years.

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.

Customer quote:

“It would be fair to say that TERMIS has been the source of cost savings amounting to USD 25 million and a key driver that has kept the price of sustainable heating at one of the lowest levels in the global market place.“

Magnus Foged, Head of department, Engineering group at Copenhagen Energy

Customer quote:

“In a near future we will be able to see the actual temperature and pressure in the whole net, which is really useful when dealing with customers and optimizing the system on a daily basis.“

Daniel Lindblom, Project manager at Copenhagen Energy

Customer quote:

“After implementing the tool, Copenhagen Energy will save approximately 10 mio DKK per year due to lower heat loss in the net.“
