By the beginning of 2017, Middelfart Municipality has reduced CO2 emissions from the total street lighting system by 75 percent. The financing of the modernisation of the lighting system breaks even - the energy savings pay for the work.
2648 tonnes each year. This is how much Middelfart Municipality has now reduced CO2 emissions through the energy upgrade of 100 public buildings - and the first stages of the renovation of the overall system of street lighting. If one estimates that an average detached house emits three tonnes per year, this reduction corresponds to the emissions from the water, heating and electricity consumption of approximately 880 detached houses.
The refurbishment of the total street lighting system, which is under way, is based on the ESCO model. This means that energy savings pay for the work being carried out - without financial risk to the municipality and, hence, the taxpayers.
The ESCO-refurbishment of the municipality's street lighting was initiated in 2012. The contract continues for 15 years until 2027.
The reason why CO2 reduction is already at 75 percent is that the replacement of the oldest and most outdated lights is has been given first priority.
When Middelfart Municipality began refurbishing the street lighting, the system was worn out and, at the time, it was estimated that its modernisation would cost DKK 28 million spread over future capital expenditure budgets. By employing the ESCO model, the municipality saves that money while providing a modern and energy-efficient solution. At the same time, we replace the old light fittings with new ones without mercury.
