INVITATION to PhD defense

May 2019
Flexible district energy plants have an important role in the transition to a renewable energy system and may become major actors in integrating wind and solar power, when equipped with amongst others combined heat and power units and heat pumps producing both heating and cooling, and when equipped with large energy stores.

On June 7th Anders N. Andersen, head of the Energy Systems Department at EMD International A/S, will defend his PhD thesis concerning the development of next generation energy system simulation tools (as energyPRO) for designing and operating these plants.

Comparison between energyPRO and other solver methods published

March 2019
A major comparison between the economic optimization made by energyPRO (called the analytic optimization method) and other solver methods has been made and published in Elseviers peer reviewed paper Energy. The comparison show that the economic optimization in energyPRO matches fully other solver methods, when modelling flexible district energy plants equipped with CHP´s, heat pumps and large thermal energy stores.

Throughout April 2019 you can get a free copy of the article here:

EMD in Berlin

January 2019
EMD International A/S is presenting at the German conference “ZUKÜNFTIGE STROMNETZE”,, in Berlin 30.-31. January, the Danish experience of District Energy plants participating market based in the integration of intermittent productions from wind energy and photo voltaic.


EMD in Japan

November 2018 

EMD International A/S participates in the 7th REVIVAL OF FUKUSHIMA Renewable Energy Industrial Fair 2018, and Anders N. Andersen, Head of the Energy Systems Department, has presented EMD´s proposal towards 100% Renewable Energy in Fukushima prefecture. Ambassador Freddy Svane from the Royal Danish Embassy in Tokyo introduced his presentation and stressed the importance of using software tools like the ones developed by EMD to plan an energy system without fossil fuels.

New energyPRO 4.5 released

September 2018

energyPRO 4.5.358 has been released. In addition to a number of corrections, we would like to mention the following improvements.

Improved calculation of electric units, including electric stores. With this third version of energyPRO 4.5, we have improved the calculation of electric stores, such as batteries and hydro pumped storages. The electric store will try to charge when the electricity costs are low and discharge when the electricity costs are high. Also, when having both electricity producing units and electricity consuming units, energyPRO will investigate whether it will be optimal to operate them simultaneous.

Demo mode. It is now possible to shift from an unregistered module to a registered module and save the project. If you from a colleague or external business partner receives a project file, where Finance, Account or Operation is used and you only have energyPRO with Design, energyPRO will enter Demo mode. You can now convert it to Design and save it and continue your work.

Introduction window when starting energyPRO in demo mode. When in Demo, you will meet an introduction window, informing you about your options when in Demo and giving you the options of requesting a test license, going to activation window or to continue in Demo mode.

GDPR. energyPRO is now in compliance with the EU’s General Data Protection Regulation, GDPR. You will be informed about which personal data energyPRO collects.

When it comes to the German CHP law, a new table is made in the report Energy conversion, annual, showing the how the different energy conversion units cover the electricity demand. Further,  some of the existing German CHP law functions are renamed and new functions are made.


Innovative combined CHP and Heat Pump approaches in district heating grids

April 2018

NATO military camps should be sustainable, but especially be resilient. The International Energy Agency has invited EMD to present how energyPRO can be used to model this. The presentation is given today at The Technical Day at the IEA EBC Annex 73 in Frankfurt and addresses the following four aspects of energy resiliency.

Case 1: A CHP-plant with a gas and electricity driven heat pump
Case 2: Booster heat pumps and central heat pumps in district heating
Case 3: Circular energy transmissions lines modelled in energyPRO
Case 4: Market optimizations of Hybrid solutions.


Article from Elsvier

March 2018

The newly released article at Elsvier, “A modelling tool selection process for planning of community scale energy systems including storage and demand side management”, concludes that energyPRO, as one out of 6, passed all essential capabilities met with the highest score.

Interesting article from Hot Cool Magazine

December 2017

The article ‘Optimal Operation of a Multi Vector District Energy System in the UK’ describes how much a PV and electrical battery can improve the economy in a district energy plant by a smart marked based operation of heat pumps and batteries.
The modelling has been made in energyPRO.

energyPRO 4.5 released

November 2017

With energyPRO 4.5 we introduce the new module COMPARE. With COMPARE you can generate alternative scenarios to a reference in one project file. You can compare the results between the reference and the alternatives, both energy conversion and cash flow. With FINANCE and ACCOUNT you can compare key financial figures, such as NPV and IRR. Further, changes made in the reference, will transpire in the alternatives.

energyPRO 4.5 starts with a Start window, where you can select among recent used files, the examples included with energyPRO and you have access to online information.

The complete list of improvements:

  • Start window
  • Automatic calculated operation strategy when having process heat
  • Improved online data access, including access to ERA5 data
  • Duration curves on charts
  • Click and drag zoom
  • Improved activation check
  • More skins
