We consult in many project types, e.g.:

• Biomass plants

PlanEnergi offers consultancy concerning biomass-based solutions for district heating production, both with and without electricity production. PlanEnergi has been the client advisor and project manager of several turnkey projects, where complete biomass plants have been established, including fuel storage and handling as well as building. PlanEnergi also handles dialogue with authorities concerning the fire&safety aspects of construction. To get consultation please turn to Anders Michael Odgaard

• Extension of district heating networks and development of new systems

The extension of district heating networks is a part of PlanEnergi’s work on strategic heat planning for municipalities and an integrated part of a number of district heating projects. Our services range from initial screening of potentials, through feasibility studies, pipe system dimensioning and hydraulic analysis to tendering process, advising in the construction process and final commissioning. Extensions of the district heating network can be calculated in the LeanHeat software, a hydraulic and thermodynamic modelling tool, which among other features simulates waterflow, pressure, temperature and energy in district heating systems. To get consultantion please turn to Tina Hartun Nielsen

• Seasonal heat storage

Since the first project with pit thermal energy storage (PTES) in Ottrupgård in 1994, PlanEnergi has been a leading consultant in large thermal storages for district heating, including implementation of 75,000 m³ PTES in Marstal, 19,000 m³ borehole thermal energy storage (BTES) in Brædstrup, 60,000 m³ PTES in Dronninglund and 70,000 m³  PTES in Høje Taastrup, Copenhagen as well as feasibility calculations of  several projects a.o. of a PTES of 1.5 2.0 million m³ in Graz, Austria. Beside that PlanEnergi works with high temperature thermal storages and storage of electricity. To get more information please turn to Geoffroy Gauthier

• Excess heat

PlanEnergi offers consultancy on the utilization and integration of excess heat into existing district heating production and offers consultancy on the utilization of excess heat within existing framework conditions. In some excess heat projects, the excess heat may be used directly in the district heating system, while in other cases the temperature is so low, that utilization of heat will have to be effectuated by extracting it with a heat pump.

• Solar district heating

PlanEnergi offers consultancy and project management of large solar heating projects. PlanEnergi was a consultant for some of the first attempts on large solar heating plants in the late 1980s, and has worked in the field ever since. Thanks to the last 30 years of development in the field, solar heating has expanded in Denmark and is now a well-known and widely used technology. For more information please turn to Daniel Trier

• Large-scale heat pumps

PlanEnergi sees a large potential in the use of heat pumps in the district heating systems of the future, and is therefore consultant and project manager in several development projects in that area. The projects are based on for example seawater, ground water and excess heat as a heat source. Besides heat pumps for district heating, PlanEnergi also assists industrial companies in the integration of heat pumps in their energy systems.
