Mer implements charging concept with PV integration and buffer storage for TecAlliance

The subsidiary of the Norwegian state-owned company Statkraft Mer Germany has implemented a comprehensive charging solution for the company car fleet of the data specialist in the automotive spare parts market, TecAlliance. The charging concept at the company headquarters in Weikersheim integrates its own photovoltaic (PV) system and a battery storage for an independent energy solution. The company aims to operate carbon neutrally by 2030. The transition to electromobility and the selection of carbon-neutral charging solutions are key to achieving this goal. Since 2022, they have been cooperating with Mer Germany, and the charging concept includes all steps from installation to maintenance and billing. After the electrification of the Cologne site, the implementation of the charging infrastructure at the Weikersheim site followed in March 2024. A total of 25 new charging points are now available for employees with electric vehicles in Weikersheim for free charging. The electricity comes directly from the company's own PV system installed on the roofs of the parking lot. Together with an additional buffer battery storage, charging can be done at any time in a cost- and performance-efficient manner.

"Through the PV integration, we now have an energy solution that not only impacts our overall carbon footprint but also has a very positive economic impact: We are saving around 80 percent of our current energy costs," explains Dimitri Boger, Lead Facility Management at TecAlliance in Weikersheim.

The photovoltaic system and the battery storage form a complete system that can supply both the building and the charging park with energy. Solar energy can provide approximately 202 kWh through the PV system. If the sun does not shine or the energy supply is insufficient, the battery storage acts as a performance buffer to ensure a consistent charging performance. This is designed for about 512 kWh. The storage was equipped with former electric car batteries and can be expanded as capacity needs increase.
