When it comes to the energy industry in the Hannover region, two key areas of focus emerge – energy efficiency and sustainable energy solutions. The city benefits from a robust framework of research, development, and application. With strategic initiatives and support from various sectors, Hannover is positioning itself as a leader in the transition to greener energy practices. Hannover’s energy sector benefits from the work of the Kompetenzzentrum für Energieeffizienz e.V. (Centre of Excellence for Energy Efficiency) and Lower Saxony’s Institut für Wirtschaft, which have forecasted substantial growth and employment prospects for the region. The area is recognised for its advanced technologies, a well-established network of businesses and research institutes, and ample funding opportunities. A key player here is the Klimaschutzagentur Region Hannover GmbH, which stimulates collaboration between various stakeholders. Additionally, enercity’s proKlima climate protection fund serves as a model program to increase demand for energy efficiency projects. These initiatives, combined with funding from state, national, and EU sources, create a fetile environment for innovation in energy efficiency and carbon reduction. The energy industry in Hannover employs 4,700 individuals in formal, socially insured positions, which represent 0.9% of the region’s total jobs across 70 businesses. The big employer is enercity, the region’s largest energy supplier, which also heavily invests in the development as well as the implementation of new technologies. Other significant companies include JA-Gastechnologie, A-Tron (a district heating manufacturer), energiewerkstatt, energieheld.de, Kraftwerk, Windwärts Energie, and GeoNet-Umweltconsulting. Hannover’s strategic location and advanced infrastructure make it an ideal base for research, development, production, and application of energy-efficient technologies. The region’s pledge to accelerate sustainability within the energy sector is further evidenced by its participation in various energy efficiency funding programs at various governmental levels, including substantial support from the EU.
