Location

Uniper's city power plant in Leiden is located in the northern part of the city center, at Maresingel 21E. With a chimney that has adorned Leiden's skyline since 1952, the plant is a recognizable landmark in the city.  

The area surrounding the plant, locally known as the Energiepark, is currently under development. The plan is to create a pleasant environment for working, living, and recreation.

About energy production

The Leiden city power plant is vital for the energy supply in Leiden. This plant converts natural gas into electricity and heat using CCGT technology (Combined Cycle Gas Turbine), also known as CHP (Combined Heat and Power).  

The plant's net electrical output is 85 MW. The residual heat generated is supplied to the local heat network, providing households with the necessary heat for hot water and heating.  

Uniper aims to be fully CO2-neutral by 2040, transitioning to alternative energy sources such as green gas and sustainable hydrogen.

Future of the city power plant

From an innovative fuel like metal powder to 'traditional' solar panels on our own roof, Uniper's city power plants contribute in many ways to a better, sustainable Netherlands. See for yourself!
