Reifegradverfahren: Was ändert sich bei BESS-Projekten?

Das Reifegradverfahren ersetzt das bisherige „First come, first served“-Prinzip durch einen neuen Ansatz: Entscheidend ist künftig nicht mehr der Zeitpunkt der Antragstellung, sondern die tatsächliche Umsetzungsreife eines Projekts. „First ready, first served“ lautet das neue Motto.

Degradation of PV systems: Actually much lower than long assumed

A recent long-term study by the BTU Cottbus shows that the actual power output degradation of PV systems—at around 0.6% per year—is significantly lower than is often assumed. For operators and investors, this means higher electricity yields over the entire lifespan of the system and noticeably better profitability for their projects.

Grid overlay with PV & BESS as a solution for redispatch reservation

The strategic grid overlay of PV systems with battery storage systems (BESS) enables project expansion despite regional capacity bottlenecks and the new redispatch reservation. Efficient utilization of existing connections minimizes curtailment risks and, according to an EWI study, saves up to 1.8 billion euros in grid expansion costs annually.

Global radiation 2025: Fourth place since measurements began

With around 1,187 kWh/m², global radiation in 2025 ranks fourth in historical comparison, underscoring the trend towards increasingly sunny years in Germany. The first half of the year, in particular, was rich in radiation, offering ideal conditions for photovoltaic systems and ensuring above-average solar yields.

The German electricity market: Actors, roles & processes

From power plant operators to end customers – the stability of the electricity system is based on clearly defined roles and highly dynamic stock market trading. In this complex environment, innovative players and intelligent grids ensure the balance between fluctuating generation and reliable availability.

Market Master Data Register Header

The Marketstammdatenregister (MaStR)

It is the central database of the energy transition and legally binding for every plant operator. Timely registration of PV systems and storage is the mandatory prerequisite for securing feed-in tariffs and avoiding severe fines.

BiPV at a Glance

Thanks to modern technologies, BiPV can now be integrated into architecture in a way that is virtually invisible, thereby significantly improving the ESG rating of real estate. Despite more demanding design requirements, building-integrated photovoltaics offer a future-proof solution for meeting solar installation requirements and achieving climate goals through material savings and the efficient dual use of urban space.

Network Package 2026

The planned “Network Package 2026“ of the BMWE

It marks the end of the priority given to renewable energy grid connections. By introducing „capacity-limited grid areas“ and the controversial „redispatch clause,“ the Federal Ministry for Economic Affairs and Energy (BMWE) is shifting the financial risk of slow grid expansion onto plant operators, which makes it much more difficult to finance new projects in congested regions.

Helicoptering as a risk to grid stability?

To make productive use of the oversupply of onshore wind power, large-scale battery storage, sector coupling, and flexible loads (demand-side management) are essential. Instead of curtailing generation, these technologies enable surpluses to be converted into hydrogen, heat, or mobility, thus stabilizing the power system during generation peaks.

ESG-compliant asset management company

ESG-compliant assets for a KAG

Through modernization roadmaps and Contracting, real estate investment companies (REICs) can implement solar power systems, battery energy storage systems (BESS), and charging infrastructure without incurring their own capital expenditures (CapEx) or operating expenses (OpEx). This resolves the tenant-investor dilemma, increases property returns through on-site power purchase agreements (PPAs), and meets the regulatory requirements of the EU Taxonomy and the Energy Performance of Buildings Directive (EPBD).

Modern hall heating: reduce costs, increase efficiency

Infrared indoor heating systems heat surfaces directly rather than the air, which minimizes energy loss and reduces CO₂ emissions by up to 70%. With an efficiency of 93%, these systems can be ideally combined with PV systems to provide sustainable heating for workspaces on an as-needed basis without incurring additional grid costs.

Heating with Photovoltaics: PV Power for Heat Pumps & Infrared Heaters

Heating with solar power reduces energy costs by 30–60%, as self-generated electricity replaces expensive grid power and fossil fuels. While heat pumps stand out for their high efficiency (COP 3–5), infrared heaters provide targeted radiant heat in high-ceilinged spaces at low installation costs and with high flexibility.

Efficiency through modern energy management systems (EMS)

A cloud-based EMS bundles all energy flows on a central platform and automates the creation of ESG and CSRD reports at the push of a button. It flexibly controls sectors such as e-mobility and heating systems, optimizes the most cost-effective energy mix, and secures additional revenue for companies in the capacity market through intelligent load shifting.

Depot charging e-mobility for commercial vehicle headers

Depot charging - e-mobility for commercial vehicles

Depotladen leverages idle times at central base stations to charge commercial vehicle fleets cost-effectively through intelligent load management and dynamic tariffs. This significantly reduces operating costs compared to diesel, avoids the CO₂ truck toll, and improves the ESG balance through the integration of PV electricity and battery storage.
