RE - Riesen Energie

RE - Riesen Energie GmbH is an independent German energy supplier based in Berlin-Adlershof. According to its official website, the company positions itself as a nationwide energy provider that serves exclusively large commercial customers (Großkunden) with electricity and natural gas at fair, day-current prices. Its self-description plays on the name: it is explicitly "kein Stromriese" — not an electricity giant — but an independent supplier focused on large-volume business clients rather than household or small-business retail customers. The company's core offering is the supply of electricity and natural gas to corporate customers. For electricity, Riesen Energie states that it guarantees the stability of the pure energy price over the contract term, giving customers planning certainty regarding their energy costs. Optionally, electricity can be supplied 100 percent from renewable sources such as hydropower, wind, photovoltaics or biomass, allowing customers to present themselves publicly as responsible and sustainable companies. For natural gas, the company emphasizes day-current pricing, high flexibility and advisory support in procurement, with purchasing timed to optimal market moments. Beyond pure supply, Riesen Energie describes its collaboration with clients as centered on security of supply as well as contractual, technical and tax-related optimizations. This positions the firm as a service-oriented energy procurement partner for large customers rather than a mass-market utility. Its website also provides downloads such as electricity labeling (Stromkennzeichnung) and information on the VAT reduction, and offers a customer portal. The company is registered as RE - Riesen Energie GmbH with its address at Ernst-Augustin-Str. 12, 12489 Berlin-Adlershof, and a telephone contact beginning with the German country code +49 30. Wikidata records it simply as a German company. It is a privately held firm; no parent company, stock listing or ownership group is indicated in the available evidence. Its market is Germany, and its customer focus is the large-customer (business-to-business) energy segment.

RE - Riesen Energie GmbH is a German energy supplier headquartered in Berlin-Adlershof. The available evidence does not specify a founding year or founder; Wikidata records the entity simply as a German company, and the official website presents the firm as an independent, nationwide energy provider. What can be established from the company's own materials is its business model and market positioning. Riesen Energie operates as an independent energy supplier (Energieversorger) serving exclusively large commercial customers with electricity and natural gas. Its website explicitly distances the company from the image of a large utility, stating that it is "kein Stromriese" — not an electricity giant — while still acting nationwide (bundesweit agierend). This framing places the company in the segment of independent business-to-business energy suppliers that emerged alongside the liberalization of the German energy market, where large customers can choose suppliers other than the incumbent regional utilities. The company's service model centers on supplying electricity and natural gas at fair, day-current prices. For electricity, it guarantees the stability of the pure energy price over the contract term, providing customers with planning certainty for their energy costs. Optionally, it supplies electricity 100 percent from renewable sources such as hydropower, wind, photovoltaics or biomass, enabling customers to position themselves publicly as responsible and sustainable businesses. For natural gas, the company emphasizes day-current prices, high flexibility and advisory support in procurement, with purchasing timed to optimal market moments — a capability it attributes to experience, patience and close market observation. Beyond supply, Riesen Energie describes its collaboration with customers as focused on security of supply as well as contractual, technical and tax-related optimizations. Its website offers downloads including electricity labeling (Stromkennzeichnung) and information on the VAT reduction, and provides a customer portal. The company is registered at Ernst-Augustin-Str. 12, 12489 Berlin-Adlershof, with a telephone contact beginning +49 30.
