Strategy for solar energy for Lyngby-Taarbæk Municipality

Denmark | December 2021 - June 2022

Through their participation in the DK2020 project, Lyngby-Taarbæk Municipality (LTM) has made a goal of net zero emission of greenhouse gasses in 2050. This sets a demand for proactive strategic energy and climate planning, which, amongst other things, will decide on how the municipality furthers the energy supply from renewable energy.

In the capital area, the options for setting up wind turbines and field-based solar panels are limited. On the other hand, the high plot ratio means there is a significant potential for electricity from roof-based solar panels. In the joint strategic energy plan for the capital area, it is therefore recommended to investigate this potential in each municipality.

In extension of that recommendation, LTM wished to work out a strategy for solar energy, which had to contain local analyses and local recommendations for placement of solar panels and solar thermal collectors on the roofs of the municipality. The analysis would also be used as input to the main energy and climate planning of the municipality and could point to what is a realistic potential for roof-based solar panels.

Ea Energy Analyses aided LTM in this task, and divided it into four work packages:

  • WP1: Economic analyses and climate effect
  • WP2: Assessment of potential
  • WP3: Area development plans
  • WP4: Conclusions and recommendations

The assessment from Ea was that solar panels on large roof areas has the most robust economy, and it was therefore recommended that LTM focused their work of furthering the use of solar panels here. At the same time, LTM could consider revisiting existing area development plans to assess whether they are unnecessarily restrictive in regard to setting up solar panels.

The project ran from December 2021 to June 2022.
