REBILD: Now Rebild Municipality is taking a step towards more green energy. The municipality's finance committee has decided to continue working on a model for establishing solar cells, which combines solar cells with a battery solution on selected municipal buildings.
The model, referred to as "Model 2", is intended to strengthen preparedness at socially critical buildings such as care centers, housing facilities, health and care facilities, and administrative functions with preparedness tasks.
The committee assesses that the solution contributes to security of supply and continuity of operations, although it does not necessarily provide the greatest direct economic benefits.
"This model combines solar cell systems with battery storage, so that selected critical functions can be maintained during a power outage," it says in the case presentation.
The decision comes after the Danish Parliament has relaxed the rules so that municipalities no longer have to establish an independent company to install solar cells on their own buildings. This has made it possible for Rebild to plan a strategic rollout without additional corporate requirements.
On this basis, the municipality carried out a screening of its buildings, which, among other things, assessed the roof's load-bearing capacity, shading conditions and material to ensure a solid decision-making basis for the work with solar energy.
Large proportion of municipal roofs approved for solar cells
The analysis was prepared by Rambøll and identified a total potential for the installation of solar cells on approximately 19,000 square meters of roof surfaces, which corresponds to an expected annual electricity production of approximately 3 GWh.
"With regard to the suitability of the roof surfaces, it is estimated that 80 percent of the suitable roofs are considered usable for solar cells," the analysis states.
The screening also pointed to three overall models for establishing solar cell systems, of which the administration recommends that work continue with model 2.
However, the committee also recommends that the municipality opens up the possibility of upgrading to model 3 with so-called intelligent energy management, if the nature and scope of the buildings make it relevant. The model may be relevant for larger and technically complex buildings with significant energy consumption, e.g. larger school and campus buildings, sports facilities and technical operational buildings.
First, a mapping of the existing electricity consumption is made. The financial part of the project is expected to be clarified during the budget negotiations, after which the matter will be sent to the city council for final approval.
