LE Energy Solutions GmbH, LEESO: 100 customers are already being actively supplied with electricity for tenants – More to follow in the Leipzig area during 2023

Leipzig, 15/06/2023 – Tenant electricity supply projects have been all the rage ever since solar panels became obligatory for new builds. However, these projects are rarely implemented. “Electricity for tenants is always greener and more affordable than the competition, offering an attractive solution for tenants,” says Matthias Pfeiffer, CEO of the Leipzig-based company LE Energy Solutions GmbH, LEESO. Since 2019, it has been part of the internationally operating Tilia Group for implementing tenant electricity supply projects. As the interface between the housing industry, electricity network operators and tenants, LEESO utilises its skills to overcome potential project-related hurdles and turn tenant electricity supply projects into a reality.
LEESO actively supplies more than 100 customers with tenant electricity as part of multiple projects, with more planned for 2023. The participant rate in tenant electricity models is almost 100%. “In many areas, sub-metered electricity is the best solution for both tenants and the environment,” explains Pfeiffer. “The electricity generation is transparent as tenants can see and touch the system. These local plants also relieve the burden on the electricity grid. The locally generated tenant electricity is used in the same place as it is generated and so does not use the grid for general supply. Last but not least, tenant electricity significantly reduces the costs for consumers.”
Pfeiffer describes two major obstacles facing the nationwide roll-out of tenant electricity projects. The first is bureaucracy: “The concept of electricity for tenants is often difficult to reproduce in the existing systems of the network operators. This poses certain regulatory and billing-related challenges,” explains Pfeiffer. The second is the high investment, planning and implementation costs involved, requiring a certain lead time to prepare and implement the concept, such as agreeing the measuring system with the grid operator. Electricity for tenants is only profitable for operators if customers purchase their electricity from them over several years. “The fear of changing supplier plays a major role here,” adds Pfeiffer.
Nevertheless, the fact that these projects have an acceptance rate of almost 100% shows “good collaboration with the real estate industry, personal customer service, on-site project management and attractive conditions,” says Pfeiffer, providing an indication of how tenant electricity projects can be successful in future.
Thanks to modern measurement technology, LEESO offers its customers access to all key user data, including via its online portal. Personal electricity consumption can be viewed in real time from any location, plus measures taken to reduce it.
In 2023, LEESO will expand its network with a residential building in western Leipzig and company headquarters in Schkeuditz with additional projects already being planned. Matthias Pfeiffer is convinced that “electricity for tenants is currently gathering speed and will increase exponentially,” as: “electricity for tenants is the most economic way of using locally generated electricity.”
