  • Decentralized energy supply - can this work? +

    Encouraged by EU directives on electricity market liberalization, the amended Energy Industry Act was passed in 2005, which allowed the energy market to be opened up to new players. The legal promotion of renewable energy systems led to a strong expansion of renewable energies. In Germany, over 30 percent of electricity is now generated from more than 1.6 million systems. With its technological platform of decentralized energy transition, Lumenaza is helping to achieve success by preventing unnecessary grid expansion, increasing local value creation and increasing transparency.

  • What does utility-in-a-box mean? +

    We offer almost all functions of an energy service provider modular and highly automated as a "utility-in-a-box". Our software platform enables all participants in the new energy world, such as utilities, producers, consumers, battery and electric vehicle owners, to connect and offers solutions for the changed energy market.

  • What is behind the term "Software as a Service"? +

    Software as a Service (SaaS) means that the software and IT infrastructure are operated by a service provider and customers can use this service cloud-based. The advantages for the customer are in particular a quick implementation, a transparent cost structure and a low investment risk. SaaS offers the opportunity to provide white label products that are offered under different names or brands. Customers decide together with Lumenaza which services of the Lumenaza platform are needed. We customize the software individually and take over maintenance and development - so our customers can concentrate on their core business.

  • How does aggregation work? +

    The term aggregation refers to the sale of electricity generated from renewable energy sources to electricity consumers or on the electricity exchange. On the stock exchange, the green electricity is treated equally alongside conventionally generated electricity and sold at the same market price. There are two ways for aggregation to producers of renewable electricity.
    Since 1 January 2012, operators of renewable energy plants can market their electricity using the market premium model. The financial differences between the previous fixed EEG remuneration for green electricity and the price achieved on the stock exchange are offset by a market premium. The amount of the average monthly market price on the electricity exchange plus the market premium exactly corresponds to the fixed EEG remuneration before the aggregation, so that the producer of green electricity does not suffer any financial disadvantages. If a producer sells renewable electricity on the electricity exchange in times of strong demand and thus at prices above the average market price, he can generate higher revenues than in the previously fixed EEG remuneration.
    Furthermore, producers can directly sell their electricity on the stock market at market prices without further support. However, this is a rather uncommon way, as the financial differences from the previous EEG allowance are too substantial.

  • How does the electricity exchange work? +

    The European Energy Exchange (EEX), headquartered in Leipzig, was founded in 2002 through the merger of the German power exchanges in Frankfurt and Leipzig. Contracts on electricity, coal and emission allowances as well as freight and agricultural products are traded or registered for clearing at EEX. EEX offers spot and futures trading for a large number of European electricity market areas. On the spot market, procurement and sales can be optimized up to 30 minutes before delivery. On the Derivatives Market, trading participants have the opportunity to protect themselves against future price change risks for up to six years. In addition, EEX offers products which, in the light of the increasing share of renewable energies in the electricity mix, enable greater flexibility in trading.

  • What is a balancing group? +

    In oder for producers of electricity to supply the correct customers and to be able to bill them, so-called balancing groups are required. A balancing group is a virtual account that establishes the connection between digital energy trading and analogue energy transfer. In this balancing group, all the entry and exit points are grouped together within one control area. The balancing group manager must ensure that the withdrawals and feed-in are balanced within each quarter of an hour.

  • How does balancing group management work? +

    In order to continuously settle the balancing group, a balancing group management is needed. This contains the creation of daily load forecasts and the monitoring of the balancing group deviation. Balancing group management also includes the conclusion of balancing group contracts, the management and support of balancing groups and the settlement of these balancing groups..
