Energy Law in Germany: More Necessary than Ever The number of regulations and stipulations in energy law has expanded manifold in the last few decades. The German core law, Energiewirtschaftsgesetz (Energy Industry Act), grew from just around eight pages in 1998 to more than 220 in 2024— partly due to policies from the EU. Similarly, the Renewable Energy Sources Act expanded from five pages in 2000 to over 130 in 2024. Regulations and bureaucracy have taken over, complicating the work of both the industry and public administration. Energy law in Germany needs to be simplified. Following the federal elections, a new government is forming, bringing opportunities to reshape policies and funding guidelines related to financing energy infrastructure, the green transition of heat supply (Wärmewende), and climate change adaptation. Regarding the heat supply transition, major challenges such as financing and a shortage of skilled workers must be addressed, all while expanding renewable energies. The law on building heating (Gebäudeenergiegesetz, GEG) must be revised to include district heating, hydrogen, and biologically produced methane solutions. Additionally, the Federal Network Agency (Bundesnetzagentur, BNetzA) should amend its stipulations to prevent the deliberate circumvention of designated hydrogen network areas (FAUNA). “Wärmewende” – How to Make Heating Green Without regulatory adjustments that preserve existing infrastructure, the Wärmewende will not succeed. These regulations should compensate for necessary modifications in infrastructure and be accompanied by adjustments in subsidy policies. Furthermore, gas distribution networks remain a pillar of stability during the district heating transition and must not be abandoned prematurely.

Predictive Battery Management System
Batteries power everything from electric vehicles to critical infrastructure, making their reliability non-negotiable. Yet managing battery systems remains a complex challenge, especially in dynamic or high-demand environments. BatteryCheck is addressing this head-on, transforming battery management from a reactive necessity into a strategic advantage. The company specialises in predictive battery monitoring and analytics, designed for manufacturers, service providers, and integrators who depend on batteries but may lack the internal expertise to manage them proactively. Offering deep, real-time insights into battery behaviour, BatteryCheck enables organisations to anticipate potential failures before they occur, ensuring consistent performance whether batteries are deployed as primary power sources or critical backups. Unlike traditional battery management systems, which primarily focus on monitoring charging cycles, cell balancing, safety, and immediate health metrics, BatteryCheck adopts a forward-looking approach. The platform aggregates telemetry data—such as voltage, current, temperature, and calculated performance metrics—through an API into its sophisticated analytics engine. After processing, it generates predictive alerts, actionable recommendations, and health forecasts, delivered seamlessly via API integration. Clients can access this intelligence through BatteryCheck’s intuitive dashboard, visualising individual battery analytics or integrating the data directly into their existing systems. In doing so, BatteryCheck empowers stakeholders to shift from reactive maintenance to proactive optimisation, ensuring batteries perform reliably and extending their operational life. Flexibility at the Core Building a truly versatile battery analytics platform required flexibility from the start. BatteryCheck’s solution is engineered to adapt across a broad spectrum of chemistries and applications, operating seamlessly whether a company relies on lithium-ion, lead-acid, or emerging battery technologies. Supporting both first-life applications, such as electric vehicles, and second-life use cases where repurposed batteries are used for energy storage, BatteryCheck delivers powerful insights through a single, intuitive interface. This flexibility extends beyond software. Recognising that not all batteries are equipped with sophisticated management systems, BatteryCheck offers a suite of third-party sensors capable of measuring current, voltage, temperature, and other key parameters. These sensors can be retrofitted onto legacy batteries and transmit real-time data via machine-to-machine (M2M) SIM cards directly to BatteryCheck’s backend, bridging critical gaps in battery fleets without costly infrastructure overhauls.
Advanced Electricity Algorithmic Trading Platform
As global demand for clean power surges, renewable asset owners—from wind farm operators to solar developers— are facing a critical question: How can fluctuating, weather-dependent generation be translated into stable, predictable revenue streams? To address this challenge, the renewable energy sector is undergoing a strategic shift—from a pure production mindset to one centered on revenue optimization. This evolution involves integrating technology, data, and financial instruments to ensure that every kilowatt-hour aligns with market opportunities. SAMAWATT stands as a trusted ally to make that shift actionable.

Designed to optimize forecasting, dispatch, and real-time market bidding, the platform routinely delivers 20 to 50 percent gains in net trading profits for clients. It connects directly to SCADA systems, weather data, and market exchanges, using high-frequency data and stochastic programming to optimize trades across day-ahead, intraday, balancing, and ancillary markets. Built for speed and scale, the SAMA-AssetTM platform eliminates the lengthy onboarding and capital investment cycles associated with legacy systems. Asset owners can begin seeing results within weeks, making it an ideal solution for utilities, developers, and virtual power plant (VPP) operators alike. After going live, each client is assigned a dedicated success engineer and has access to 24/7 support. Weekly performance reviews are conducted during the first months, ensuring complete knowledge transfer and allowing for early correction of any anomalies. SAMAWATT’s technological ecosystem extends beyond SAMA-Asset™. Its proprietary suite of algorithmic trading blueprints, SAMA-Strategies™, is explicitly built for renewable portfolios navigating wholesale power markets. This system is currently operational across 15 European countries and has been instrumental in supporting zero-imbalance, volume-shifting, and multi-market optimization arbitrage strategies. It has enabled clients to dynamically manage exposures and seize short-term pricing opportunities— unlocking new value streams that were previously out of reach. Furthermore, its specialized module for battery storage, SAMA-BATT™, employs a hybrid model that integrates digital twins of each battery system with market-based reinforcement learning. This approach optimizes charge-discharge cycles across revenue streams—from day-ahead arbitrage to frequency regulation—while minimizing battery degradation. The result is a 30 percent increase in battery-based income for clients.
