The National District Energy Office (NDEO) operates under the sponsorship of the Global Environmental Facility. It is executed by the Sustainable Energy Agency (AgenciaSE), working in conjunction with the Directorate of the District Heating Unit of the Ministry of Energy of Chile. It receives technical support from the United Nations Environment Programme (UNEP) and its global District Energy Initiative in Cities ecosystem. The NDEO’s mission is to offer technical support to bolster the capabilities of local governments and private developers in promoting and commercializing efficient and sustainable energy solutions. By facilitating local and global low-emission projects, the NDEO plays a pivotal role in assisting the country in city decontamination efforts and transitioning to a climate-resilient energy landscape.
