Kiwigrid/BayWa r.e.

Kiwigrid and Lumenaza have developed a manufacturer-independent Home Energy Management System including a customized green electricity tariff for PV storage combinations. The collaboration enables BayWa r.e. to offer a cloud-based electricity product at a flat rate in addition to a complete solution consisting of a solar system, storage, energy manager and a user-friendly app. End-consumers receive a holistic solution, from device installation to registration for the green residual electricity. Our open interfaces enabled Kiwigrid to integrate us into the existing HEMS customer portal, so that both existing and new customers can register for the tariff in just a few clicks. Lumenaza acts as a utility-as-a-service, meaning we take on the supplier role and all subsequent power market processes.
Prosumer Community


SMA Solar Technology AG is one of the world's leading specialists for photovoltaic system technology and energy solutions. With JOIN, SMA offers its customers a sustainable electricity tariff based on a decentralized and renewable energy supply. The open interfaces enabled a very fast and uncomplicated integration into the existing customer portals, so that both existing and new customers can register for the tariff with just a few clicks. Lumenaza acts as "utility-as-a-service", i.e. it takes over the supplier role and all subsequent energy management processes such as billing, switching processes, balancing group management, as well as the procurement of electricity of clear origin from the community via its virtual power plant.

Smart tariffs


Since January 2017, we have collaborated with Vattenfall on the Sun Partnership. With Vattenfall as a partner, companies can produce electricity on the roof of their own property by operating a PV system, concurrently reducing their own electricity costs and building up their fixed assets. The solar system is leased from Vattenfall in a solar contracting model so consumers do not incur high initial investment costs. We act as direct marketer, provide the internet platform and offer the residual electricity supply to commercial enterprises.

IBC Solar

In 2019, IBC SOLAR, a worldwide leading system house for photovoltaics (PV) and energy storage, launched the eco-electricity tariff efa: fair, which is based on a product tailored by Lumenaza for PV storage systems and adapted to the customer's needs. With the combination of efa:fair and efa: home, energy management platform that optimizes the energy flows within the home, customers can now get 100 percent green electricity and make maximum use of the advantages of solar systems and storage and increase their energy efficiency.
New concepts


The southern Swedish village of Simris has 140 households and feeds its energy needs almost entirely from wind power and PV systems. Excess electricity is temporarily stored in batteries or used, for example, as flexibilities in heat pumps. Lumenaza is responsible for the mapping of the energy flows. Customers can use their own platform at any time to see how much energy their plant produces and how much they have used themselves. The use of flexibilities is also mapped so users have full transparency at all times. The EU-funded research project was completed in 2021.

ANM4L - Active Network Management for All

ANM4L demonstrates how innovative active network management solutions can increase the integration of renewable energy sources in electricity distribution networks. Lumenaza provides the software platform to motivate customers to actively participate in a local energy market. The benefits of using flexibilities in active and reactive power will be shared with customers to strengthen loyalty in their communities and avoid expensive investments in grid extensions. Lumenaza is collaborating with RISE Research Institutes of Sweden, the Municipality of Borgholm, E.ON, Lund University and RWTH Aachen University on this project, .
