The amendments passed in the Bundestag on January 31, 2025, as part of the Solar Peak Law, have far-reaching effects on EEG plant owners, aggregators, and energy suppliers. Owners of new PV systems are particularly affected, as they can not only avoid losses in aggregation but also generate additional earnings through corresponding flexibilities. With Lumenaza's flexible SaaS platform, tailored energy offerings can be developed and cost-effectively brought to market, even for prosumers with small or medium-sized systems.

With the new legal amendments, operators of new EEG plants will no longer receive compensation for injected electricity when market prices are negative. Remaining in the EEG compensation scheme leads to financial losses of approximately 30% for new installations. Switching to aggregation not only compensates for these losses but can also generate additional earnings. These additional earnings are particularly beneficial for system owners with battery storage, electric vehicles, and smart home energy management systems (HEMS).

However, not all aggregator and hardware providers are yet prepared for the changing conditions. Only a few OEMs offer their hardware as a complete package with integrated aggregation solutions and dynamic tariffs for electricity supply, often based on Lumenaza’s optimized SaaS platform. These intelligent approaches point towards a future in which PV systems and battery storage are worthwhile even without subsidies.

Increased Demand for Aggregation and Smart Storage Systems?

‍

Aggregation offers prosumers a remuneration model that allows them to benefit from market price fluctuations. By combining PV systems with storage, electricity generation can be shifted to high-price evening hours.

A home energy management system (HEMS) can take over intelligent control based on price signals to shift energy injection. When a 15 kWp system is combined with a 30 kWh storage unit, around 52% of total summer energy injection can be optimized for higher prices.

The immediate additional earnings in 2025 are just the beginning. The law also includes the so-called flat-rate option, which enables home and EV batteries to be charged from the grid and discharged back into it. This makes bidirectional charging (Vehicle-to-Grid) possible, with market implementation expected by 2026.

Which Providers Can Benefit from the Changing Conditions?

‍

Many owners of small and medium-sized PV systems are still struggling to find a suitable provider for aggregation of their generated electricity. Most aggregator consider such systems uneconomical.

Lumenaza’s virtual power plant has been designed to accommodate the aggregation of medium-sized and small systems. The high level of automation and low cost-to-serve of Lumenaza enables electricity providers and aggregator to bring profitable business models for these segments to market.

Many customers expect their hardware providers to offer a comprehensive solution portfolio that meets their needs. Integrating dynamic electricity tariffs or aggregation can therefore be beneficial. With Lumenaza’s white-label solutions for aggregation and electricity tariffs, OEMs can enhance their products with corresponding energy offerings without having to build a comprehensive IT infrastructure themselves.
