Since 1987, Koninklijke Oosterhof Holman has owned 20 hectares of the site adjacent to Schenkenschans. Although unused for many years, the vision began to take shape in 2007 when former managing director Harm Beerda envisioned a park integrating all of the company's capabilities, including the provincially owned Schenkenschans. Beerda imagined waterborne transport and biomass digestion linked to sustainable asphalt production—ideas aligned with early government sustainability goals and the company's future vision. Despite initial enthusiasm, especially for a 'green asphalt plant', public resistance led to the shelving of these plans. The concept was revived in 2014, this time focusing solely on the sustainable campus vision, which gained broad support. Atop the former landfill, a unique, lightweight, and circular building has been realized: the Energie Kenniscentrum Leeuwarden. Developed by Koninklijke Oosterhof Holman and Ekwadraat, this facility hosts both organizations and offers space for additional tenants.

The Energiecampus stands for action rather than words when it comes to sustainability. It is a hub for collaboration among businesses, knowledge institutions, and governments, with the aim of making the energy transition concrete. The guiding principle are: dream, think, dare, and do. It is located to the west of the city of Leeuwarden, the Energiecampus has excellent connections to the N31 highway and the Van Harinxma Canal. The 48-hectare site includes the Schenkenschans, a striking landmark for the Frisian capital and its surroundings. Once a landfill, this site is now a symbol of sustainability and multifunctionality, offering space for work, recreation, and experimentation. The landscape has been carefully integrated into the surroundings, featuring a spacious green zone with water, a six-meter-high dyke, and a recreational cycling path, creating an attractive green edge to the city.

The campus is energy self-sufficient and provides green electricity for at least 4,000 households in Leeuwarden. Solar energy and anaerobic digestion are central to its energy production, with potential for expansion into other renewable sources. The solar park—installed on the land and slopes of the Schenkenschans, as well as on building rooftops, is developed by Elize Energie, a subsidiary of Koninklijke Oosterhof Holman. Following the experience with an anaerobic digester at the Dairy Campus, a new digester is being constructed at the Energiecampus. The first phase will process 100,000 tons of organic material annually using the innovative Hogen process from the United States. Currently, the Elfstedenhal sports facility still uses landfill gas from the Schenkenschans. Once that source is depleted, the gas line can be connected to the biogas from the digester. In later stages, additional digesters of the same capacity may be added and linked to the district heating system. A loading and unloading quay on the Van Harinxma Canal enables sustainable transport by water. This benefits nearby businesses and supports the regional soil collection bank (GBT).

Today, the Energiecampus Leeuwarden continues to evolve, anchored by the Energy Knowledge Center. It serves as a hub for stakeholders working toward the energy transition, embodying the collaborative spirit: dream, think, dare, and do.
