AFIR is the EU regulation on the deployment of alternative fuels infrastructure. Operators of public charging points have had obligations on ad-hoc payment, price transparency and data provision since 2024; from 8 January 2026 ISO 15118-2 is mandatory for new charging points, from 2027 ISO 15118-20 with plug and charge. Utilities operating charging points must adapt back end and processes.
AI systems that autonomously pursue goals, make decisions and execute multi-step tasks without constant human guidance. Unlike traditional AI applications that respond to individual queries, agentic systems actively plan and dynamically adapt their approach. In enterprise practice, this means AI agents that take over entire workflows, not just individual steps.
An aggregator pools generation plants, storage and flexible demand of many customers and markets them together, for example as a virtual power plant. The German Energy Industry Act has defined the role since 2021 (section 3 no. 1a EnWG). For grid operators and suppliers this creates new data flows between balancing group, metering point and control.
AgNeS is the Federal Network Agency's ruling procedure for a new electricity grid charge system that replaces the StromNEV from 2029. It provides for time-variable charges, capacity prices and feed-in charges. The consultation ended in September 2026, the framework ruling follows by end of 2026, follow-up rulings in 2027. Grid operators have to adapt billing, metering concepts and tariffs.
An autonomous software system that perceives its environment, makes decisions and takes actions to achieve specific goals. AI agents differ from simple chatbots through their ability to use tools, create plans and independently execute multi-step tasks. In enterprises, they are increasingly deployed for research, data analysis and process automation.
An application programming interface through which software systems exchange data and functions in a structured way. APIs are the connective tissue of modern IT, and in AI the primary path to models: applications call language models, embeddings or agents via APIs. Well-designed, documented and secured APIs determine integrability, scaling and vendor independence.
Hypothetical AI systems that can understand and solve any intellectual task that a human can accomplish, including reasoning, learning and creative problem-solving across domains. AGI does not exist today; current systems like LLMs are specialised (narrow) AI. The debate around AGI is central to long-term AI strategies and regulation.
AS4 is the transport channel for market communication messages, a standard built on ebMS3 and web services with signing and encryption. In the electricity market it has been mandatory since 1 April 2024, replacing email and AS2. Running AS4 requires valid certificates from the smart meter PKI and an endpoint that stays reachable. If the channel goes down, supplier switches and meter data transfer stop.
Balancing energy offsets short-term deviations between generation and consumption and keeps the grid frequency at 50 hertz. Transmission system operators procure it in auctions as frequency containment, automatic and manual frequency restoration reserve; European platforms such as PICASSO and MARI link the markets. Storage and aggregators can take part after prequalification.
A balancing group is a virtual energy account in which a market participant's injections and withdrawals are netted per quarter hour. The balancing group responsible party must keep it balanced; every deviation is settled by the transmission system operator as imbalance energy at the reBAP price. The framework is the standard balancing group contract BK6-23-102, and settlement follows MaBiS. Poor forecasts cost money here directly.
Since 2021 the BEHG has put a price on the CO2 emissions of heating and transport fuels in Germany. The obligated parties are those who place the fuels on the market, for example gas suppliers, who pass the costs on to their customers. The national system is meant to move into the European emissions trading for buildings and transport.
BEW is the federal funding programme for building and converting heat networks supplied at least 75 percent from renewables or unavoidable waste heat. It covers up to 40 percent of eligible costs and is run by BAFA. Since 1 April 2026 it no longer funds transformation plans; feasibility studies, planning and construction remain eligible. Heat network operators still have to submit the decarbonisation roadmap under section 32 WPG.
Germany's Federal Office for Information Security is the national cybersecurity authority. It defines standards (such as IT-Grundschutz), issues threat warnings and publishes guidance, increasingly on the secure use of AI in enterprises and public administration. For regulated sectors, BSI requirements are a de-facto compliance benchmark.
Beyond Visual Line of Sight, drone operation outside the pilot's direct field of view. BVLOS flights can cover whole line corridors in one go and are the prerequisite for cost-effective drone inspection of power grids. In the EU they fall into the specific category of drone regulation 2019/947 and require an operational authorisation from the national aviation authority.
A capacity market pays power plants for keeping capacity available, not only for the electricity they produce. Germany is planning such a mechanism to finance new dispatchable plants that step in when there is little wind and sun. For utilities with their own plants the design decides on investment and revenue.
The charge point operator runs public charging stations technically and commercially. It carries the obligations of AFIR and the German charging station ordinance, from ad-hoc payment to price display, and connects its stations to the back end via OCPP and to eRoaming platforms via OCPI. Many utilities are CPOs themselves. The charger is rarely the problem; the back end almost always is.
Clean Core is the SAP principle of keeping the standard core of an S/4HANA system free of custom developments and building extensions decoupled on the Business Technology Platform. For energy utilities this means assessing, cleaning up or encapsulating decades-old IS-U custom logic so that upgrades, MaKo releases and AI functions remain possible without special effort.
CLS management bundles the processes by which an active external market participant sends control commands to control boxes, heat pumps, wallboxes and storage via the CLS channel (Controllable Local Systems) of the smart meter gateway. It covers roles, keys, communication profiles and evidence. For control under §14a EnWG it is the operating basis of the grid operator or a commissioned service provider.
The systematic design and optimisation of the context available to an AI model during processing. This includes system prompts, example data, document selection and instruction design. Context Engineering goes beyond Prompt Engineering because it shapes the entire information architecture around the model, not just the individual input.
The control box is the BSI-certified device that receives control commands via the smart meter gateway and passes them to controllable consumption devices or generation plants, for example dimming a heat pump to 4.2 kW under §14a EnWG or curtailing a PV system under the solar peak law. Grid operators and metering point operators have to organise ordering, installation and operation at scale.
Under section 14a EnWG, controllable consumer devices are heat pumps, private wallboxes, air conditioners and battery storage above 4.2 kW that went into operation from 1 January 2024. The grid operator may dim them to as low as 4.2 kW when congestion threatens, and in return must connect them rather than refuse the connection. The customer receives reduced network charges under module 1, 2 or 3.
A customer installation is an energy installation behind the grid connection that supplies several final consumers without being regulated as a grid, for example in apartment buildings or business parks. After the CJEU judgment C-293/23 and the Federal Court of Justice decision of May 2025 the term is interpreted narrowly; since 2026 grandfathering applies and new constellations must be organised as a grid or as tenant electricity.
The Cyber Resilience Act, Regulation (EU) 2024/2847, obliges manufacturers of products with digital elements to apply security by design, manage vulnerabilities and provide a software bill of materials (SBOM). Since 11 September 2026 manufacturers must report actively exploited vulnerabilities, and from 11 December 2027 the regulation applies in full. Scope runs from the inverter to the control software in the control room. For utilities as buyers, the CRA becomes a question in every tender.
Control over where data is stored and processed and which jurisdiction governs it. For European organisations it means being able to run critical data and AI workloads independently of non-European providers and legal regimes. It is a core driver of sovereign-AI and EU cloud initiatives.
The default metering point operator is usually the distribution system operator and carries the rollout obligations under MsbG with quotas of 20, 50 and 95 percent by 2025, 2028 and 2030. Competitive metering point operators take over metering points at the customer's request. Since 1 July 2026 standardised metering contracts (BK6-24-125) apply to default operators.
AI agents deployed as full team members with defined roles and responsibilities within organisations. The innobu Digital Colleagues framework gives AI agents concrete job titles such as Architect, Strategist or Analyst and integrates them into existing governance structures. The approach solves the most common problem in AI projects: the technology works, but nobody agrees on what it should actually do.
A digital secondary substation is a medium-to-low-voltage substation with sensors, telecontrol and communication that delivers low-voltage measurements to the control centre and allows remote switching. Large grid operators are retrofitting tens of thousands of substations by 2026; they are the core of grid state estimation for §14a and low-voltage redispatch.
The deep redesign of an organisation's business models, processes and culture using digital technologies, more than digitising individual workflows. Successful transformation ties technology, data and workforce enablement to clear business goals. AI is currently the strongest driver and test of this change.
A virtual representation of a physical object, process or system that is synchronised with real-time data. In the energy sector, digital twins are used to model grid infrastructure, simulate loads and plan maintenance proactively. The value comes from connecting sensor technology, data platforms and decision support.
In direct marketing, a direct marketer sells the output of an EEG plant on the exchange, and the plant operator additionally receives the market premium. It is mandatory for new plants from 100 kW. From 25 kW the plant must be remotely controllable (section 10b EEG), via smart meter gateway and control box from 2028 at the latest. For grid operators every plant in direct marketing means its own processes under GPKE.
A distribution system operator runs the electricity or gas grid at medium and low voltage or on the lower pressure tiers, the grid right up to the service connection. Germany has several hundred of them, most of them municipal utilities or their grid subsidiaries. Section 14a EnWG, the section 14d grid expansion plan, the grid connection portal and redispatch all land on the DSO. The energy transition gets connected in the distribution grid, not the transmission grid.
A digital twin of a district heating network is a hydraulic-thermal model of the network that is continuously reconciled with measurements from substations and generators. Utilities use it to lower the supply temperature, to integrate decentralised feed-in and large heat pumps, and as the data basis for heat planning and the decarbonisation roadmap.
A dynamic electricity tariff passes the exchange price through to the customer, so the energy price moves with the day-ahead market. Since 1 January 2025 every supplier has had to offer one (section 41a EnWG), and since October 2025 prices are set per quarter hour. The customer needs an intelligent metering system. Without automated control of the heat pump or wallbox, the benefit for most households stays small.
EDIFACT is the message format German market communication has run on for years. Message types such as UTILMD (master data), MSCONS (meter readings) or INVOIC (invoices) are defined in the BDEW's EDI@Energy rules and change with every format release, usually in April and October. The Federal Network Agency is replacing EDIFACT step by step with API web services. Both worlds will therefore run side by side for years.
Since 2000 the Renewable Energy Sources Act has supported power from solar, wind, biomass and hydro, through a fixed feed-in tariff or the market premium in direct marketing. It also governs grid connection of such plants and, since 2025, the grid connection portal. The Solar Peak Law removed payment at negative prices in 2025, and the draft EEG 2027 takes the fixed tariff away from small new PV systems. Every change hits grid operators, metering operators and market communication at once.
An energy data space is a federated infrastructure under Gaia-X principles in which market actors share energy data sovereignly without handing it over centrally. At EU level the Common European Energy Data Space (CEEDS) is emerging; in Germany the lighthouse project energy data-X with four transmission system operators ran until October 2026. For utilities it is about interfaces, data quality and data governance.
Energy sharing under §42c EnWG allows energy communities to jointly use and settle locally generated electricity within a grid area. Since 1 June 2026 grid operators must enable the settlement; the Federal Network Agency platform under §20b EnWG makes mass operation realistic only from 2027.
The complete description of an organisation's structures: business processes, IT systems, data flows and technology infrastructure. Enterprise Architecture creates transparency about how individual systems interact and provides the decision basis for investments in technology and transformation. Without EA, every large programme becomes a blind flight.
The Energy Industry Act is the core law for grid-bound electricity and gas supply in Germany. It governs grid operation, unbundling, grid access and supply, and is amended almost every year. Many of a utility's duties hang on single sections: section 5c for IT security, section 14a for controllable consumers, section 41a for dynamic tariffs, section 42c for energy sharing. The section number often tells you faster than the title who is affected.
The European AI regulation (Artificial Intelligence Act) that establishes a risk-based regulatory framework for the deployment of AI in the EU since 2024. Systems are classified into risk categories, from minimal to unacceptable. High-risk systems are subject to strict requirements for transparency, data quality and human oversight. For enterprises, the EU AI Act means concrete compliance obligations that must be implemented now.
EU Regulation 2019/947, which governs the operation of civil drones across Europe. It splits flights into the open, specific and certified categories. Commercial BVLOS inspections of power grids fall into the specific category and need an operational authorisation based on SORA, a standard scenario or a PDRA.
EU ETS 2 is the European emissions trading system for fuels used in buildings and road transport. In Germany it replaces the national system under the BEHG; its start date is politically disputed. Gas and heat suppliers should therefore plan pricing and billing for more than one start date.
The Federal Network Agency in Bonn regulates, among other things, the German electricity and gas grids. Since the 2021 CJEU ruling on regulator independence it increasingly sets network charge methodology and market processes itself by determination rather than through federal ordinances. Its ruling chambers carry codes such as BK6 (grid access and market communication, electricity) or BK8 (electricity charges). A determination number like BK6-24-125 is an obligation with a date attached.
The gas network transformation plan is a gas distribution operator's plan for converting its network to hydrogen, biomethane or decommissioning by 2045, aligned with municipal heat planning. The H2vorOrt and DVGW guide sets the methodology; the EnWG gas package 2026, implementing the EU gas directive, creates the legal frame for decommissioning and repurposing.
Gas transmission system operators run Germany's long-distance gas transport network and market entry and exit capacity. Together they draw up the network development plan for gas and hydrogen, and many of them will also operate parts of the hydrogen core network.
The smart meter gateway administrator operates and manages the smart meter gateways on behalf of the metering point operator: configuration, certificates, firmware, tariff use cases and secure communication under BSI TR-03109. A GWA must be certified by the BSI; from 1 January 2027 new and re-certifications follow TR-03109-6 version 2.0.
The EU's General Data Protection Regulation has governed the processing of personal data since 2018. It requires a legal basis, purpose limitation, data minimisation and data-subject rights, with fines of up to 4 percent of global annual turnover. For AI projects it is the central framework: training data, prompts and model outputs containing personal data must be GDPR-compliant, forcing anonymisation, data-processing agreements and impact assessments.
The Building Energy Act sets the energy requirements for buildings and their heating systems. Since 2024 new heating systems are meant to run on 65 percent renewable energy; the duty is tied to the deadlines of municipal heat planning. For utilities it drives connection demand in the heat network and sales in the gas network.
AI systems that can create new content such as text, images, code or music, rather than just analysing or classifying existing data. The best-known examples include ChatGPT, Claude and Midjourney. Generative AI is typically based on large pre-trained models (foundation models) and has fundamentally changed the discussion around AI in enterprise contexts since 2023.
GPKE (business processes for supplying customers with electricity) is the Federal Network Agency's determination covering start of supply, end of supply, master data changes and network usage billing for electricity. Since 6 June 2025 it also includes the former MPES processes for feed-in points. The 24-hour supplier switch runs through GPKE as well. For a utility with both grid and retail, that means both sides of the same message in one house.
A grid connection portal is the digital platform through which connection users and installers apply for grid connections and generation plants, submit documents and track status. Under §8(7) EEG grid operators have had to offer such a portal since 2025; the grid package provides for capacity maps and reservations from 135 kW from 2027. It is the most visible digitalisation process between grid operator and customer.
Grid state estimation is the calculation of the current state of a low-voltage grid, meaning voltages, currents and loading, from measurements at a few points plus a grid model. The VDE FNN guidance recommends measurements from at least 20 percent of connection users, or transformer feeder plus 10 percent, at one-minute resolution. It is the data basis for grid-oriented control from 2029.
Grid-oriented control is the form of control under §14a EnWG that becomes binding from 2029: the distribution system operator intervenes only in an actually measured congestion, based on grid state data from the low-voltage grid. Until end of 2028 the transition period with preventive control by fixed rules applies. Prerequisites are grid state estimation, control boxes, CLS management and a low-voltage control system.
A grid-scale battery is grid-connected storage in the megawatt range, usually in containers next to a substation. It earns money on the wholesale and balancing markets and can relieve grid congestion. Connection requests far exceed the available grid capacity, which turns connection procedures and flexible connection agreements into the bottleneck.
A guarantee of origin proves electronically that one megawatt hour was produced from renewable sources. In Germany the Federal Environment Agency keeps the register for electricity; separate registers are added for gas, hydrogen, heat and cooling. Suppliers need the certificates for electricity disclosure and green power products.
The phenomenon where AI models generate plausible-sounding but factually incorrect or entirely fabricated information. Hallucinations are not a bug but a systemic characteristic of generative models that operate on probabilities. For enterprise use, this means every AI output needs verification mechanisms. RAG, grounding and human oversight are the most important countermeasures.
The Heat Planning Act obliges municipalities to carry out municipal heat planning: cities above 100,000 inhabitants by 30 June 2026, all others by 30 June 2028. The plan designates areas for heat networks, hydrogen networks and decentralised supply. Under §32 operators of existing heat networks must submit a decarbonisation roadmap by end of 2026. Utilities provide the data basis and network planning.
HEDWIG is the Federal Network Agency's data portal under §111g EnWG, to which grid operators and other market actors must deliver pseudonymised energy market data so that authorities and research can evaluate the energy market. The consultation on data scope and pseudonymisation ran until May 2026; the delivery obligation requires new interfaces and data protection processes.
A home energy management system controls heat pump, wallbox, storage and PV system in a building and receives the grid operator's §14a EnWG limits via EEBUS and the CLS channel of the smart meter gateway. Instead of dimming each device individually, the grid operator only tells the HEMS the permitted total power.
The hydrogen core network is the starter grid for hydrogen approved by the Federal Network Agency in October 2024, some 9,000 kilometres long and entering service in stages until 2032. More than half of it consists of converted natural gas pipelines. It is financed through a ramp-up charge and an amortisation account, and capacity has been reservable since 19 March 2026. For gas distribution operators, proximity to the core network helps decide what is realistic in the gas network transformation plan.
An intelligent metering system combines a modern metering device (mME), a digital meter, with a smart meter gateway that transmits the readings securely. Only the combination enables quarter-hour values, dynamic tariffs and control under section 14a EnWG. It is mandatory among other cases from 6,000 kWh annual consumption, from 7 kW generation capacity and for controllable consumer devices. All other meters must be at least an mME by 2032.
An ISMS is the set of rules an organisation uses to plan, implement, review and improve information security, under ISO 27001 and, for the energy sector, supplemented by ISO 27019. The IT security catalogue under section 5c EnWG requires grid operators to hold a certified ISMS. The certificate proves the process, not the security of each individual device. OT security and the Cyber Resilience Act cover that part.
The Federal Network Agency's IT security catalogue under §5c EnWG obliges grid operators to run an ISMS under ISO 27001 for grid control technology and, since the 2026 version, to operate attack detection systems in OT networks. Implementation must be evidenced; it affects control technology, telecontrol and the connection of digital secondary substations.
The KRITIS umbrella act has regulated the physical and organisational protection of critical facilities since 17 March 2026, complementing digital cybersecurity under NIS2. Operators must register with BBK and BSI, carry out risk analyses and submit resilience plans. The original registration deadline was dropped; the ordinance sets the dates.
The KWKG supports electricity from plants that produce power and heat at the same time, through supplements per kilowatt hour. The support is financed by the KWKG levy on the electricity price. For utilities with district heating it is one of the main sources of funding, including for innovative CHP systems with heat pumps and storage.
Large neural networks trained on extensive text data that can understand and generate natural language. LLMs such as GPT-4, Claude and Gemini form the foundation of the current generative AI wave. They work with tokens, use the Transformer architecture and are optimised for specific applications through fine-tuning and Reinforcement Learning from Human Feedback (RLHF).
A term coined by Simon Willison for the dangerous combination of three capabilities in one AI agent: access to private data, exposure to untrusted content, and the ability to communicate externally. When all three meet, a prompt injection can exfiltrate data unnoticed. The takeaway: design agents so the three never coexist.
The Luftfahrt-Bundesamt is the German authority that grants operational authorisations for drone flights in the specific category. For new BVLOS applications the LBA has assessed them on the basis of the SORA 2.5 methodology since 1 January 2026; processing usually takes several weeks to months.
The MaBiS hub is the central platform for electricity balancing settlement defined by the Federal Network Agency, replacing today's decentralised aggregation at distribution system operators. The introduction is split into two blocks: ruling on block 1 (meter data processing) in 2026, go-live in the second half of 2028. Grid operators and suppliers have to adapt interfaces and master data.
A subfield of artificial intelligence where algorithms learn from data and recognise patterns without being explicitly programmed. The three main categories are supervised learning (with labelled data), unsupervised learning (pattern recognition in unstructured data) and reinforcement learning (learning through reward). Machine learning is the foundation of virtually all modern AI applications.
The market area manager runs the German gas market area: it settles the balancing groups, operates the virtual trading point and procures balancing energy for gas. Since October 2021 there has been a single market area in Germany, run by Trading Hub Europe.
Market communication is the standardised electronic data exchange between the market roles of the German energy sector, such as grid operator, supplier and metering point operator, for processes like supplier switching, balancing and meter data transfer. The Federal Network Agency defines the processes (GPKE, GeLi Gas, MaBiS, WiM) and formats (EDIFACT, in future API) and publishes two binding releases a year, on 1 April and 1 October.
The market location is where energy is consumed or generated and billed; it carries an eleven-digit MaLo ID. The metering location is where measurement happens, with a 33-character ID. One MaLo can have several MeLos, for example a heat pump with its own meter. Many exception cases in market communication start with a wrong mapping between the two.
The Federal Network Agency's market master data register records every generation plant, storage unit and market actor in the German power and gas market. Plant operators must register, grid operators check the entries. The data underpins EEG payments, redispatch and many reporting duties.
Since 2016 the Metering Point Operation Act has governed who installs and operates meters, what that may cost and how fast the rollout of intelligent metering systems must go. Mandatory cases are to be 20, 50 and 95 percent equipped by the end of 2025, 2028 and 2030. The February 2025 amendment raised the price caps for the first time since 2016, retroactive to 1 January 2025. The Federal Network Agency now enforces the quotas through supervisory proceedings.
MiSpeL is the Federal Network Agency's ruling on the market integration of storage and charging points. It regulates how bidirectional storage and charging points are balanced and which grid charges apply, and removes the double burden of grid charges. The ruling is published on 1 October 2026; automation in market communication follows from 2027.
An open standard that enables AI models to access external data sources and tools in a structured way. MCP was initiated by Anthropic and works like a universal adapter: instead of building a custom integration for each data source, MCP provides a standardised interface. For enterprises, this reduces integration effort and improves interoperability between AI systems.
An architecture in which multiple AI agents collaborate to solve complex tasks. Each agent has specialised capabilities and a defined role; coordination happens via protocols or an orchestration agent. Multi-agent systems enable the decomposition of complex problems into manageable sub-tasks and are the foundation for scalable AI operating models.
A subfield of AI concerned with the processing, understanding and generation of human language. NLP encompasses tasks such as text classification, sentiment analysis, named entity recognition, machine translation and question answering. Modern LLMs have revolutionised NLP: tasks that required specialised models just a few years ago are now solved by generic language models as a side effect.
NEST refers to the Federal Network Agency's rulings of December 2025 on the new incentive regulation replacing the ARegV. The fifth regulatory period starts in 2028 for gas and 2029 for electricity, followed by three-year periods. New are quality elements on digitalisation and energy transition capability that may carry revenue consequences in future.
Network charges pay for the use of the electricity or gas grid. The grid operator bills them to the supplier, who passes them on to the end customer; for household electricity they make up about a quarter of the price. How much a grid operator may earn in total is set by incentive regulation through the revenue cap. Provisional charges for the following year must be published by 15 October, and from 2029 AgNeS is due to restructure the system.
The EU's NIS2 Directive tightens cybersecurity obligations for operators of essential and important entities, including energy, health, digital infrastructure and public administration. It mandates risk management, incident reporting within 24 hours and personal liability for management, pulling far more organisations into scope than its predecessor.
Software whose source code is open to inspect, use and modify. In AI the spectrum ranges from open weights to fully open training data and recipes. Open-source models offer control, auditability and sovereignty, but shift responsibility for operation, security and compliance in-house.
OT security protects operational technology: control systems, telecontrol and protection equipment in substations, secondary substations and generation plants. Unlike office IT, availability comes before confidentiality, and devices often run for twenty years. The benchmark is the IEC 62443 series with zones and conduits; since May 2023 the EnWG also requires grid operators to run attack detection systems. A patch that is routine in the office can be a project in the control room.
A PPA is a long-term power supply contract directly between a generator and a buyer, often for ten years or more. It can be settled physically or purely financially and mainly finances wind and solar parks without EEG support. For utilities a PPA touches procurement, the balancing group and guarantees of origin at once.
A middle path defined by EASA between a standard scenario and a full individual SORA. A PDRA describes a typical operation with risk already assessed, so operators use the ready-made template instead of producing the complete risk analysis themselves.
The art and science of formulating input instructions (prompts) for AI models to achieve optimal results. This includes techniques such as chain-of-thought prompting, role instructions, format specifications and few-shot examples. Good prompt engineering can drastically improve the quality of AI outputs without needing to modify the model itself.
An attack vector where malicious instructions are injected into the input of an AI model to manipulate its behaviour. In indirect prompt injection, instructions are hidden in data sources that the model processes, such as websites or documents. Prompt injection is one of the biggest security challenges for AI systems in enterprise deployment.
Quality regulation is the part of incentive regulation that assesses grid operators via indicators such as SAIDI (interruption duration) and, in future, degree of digitalisation and energy transition capability. In July 2026 the Federal Network Agency published a map of Germany with these indicators for the first time, without revenue consequences yet; under NEST they may become bonuses and penalties.
An architecture that enriches AI models with external knowledge by retrieving relevant documents before generating a response. Instead of relying solely on training knowledge, the system searches a knowledge base and inserts relevant information into the context. RAG reduces hallucinations, keeps answers current and enables the use of proprietary enterprise data without retraining the model.
Redispatch is the grid operator's intervention in the output of generation plants to avoid grid congestion. Since Redispatch 2.0 (2021) plants from 100 kW and controllable small plants are included, with data exchange via Connect+. Redispatch 3.0 extends the procedure to market-based flexibility and small plants in the low-voltage grid (VDE SPEC 90032).
REMIT is the EU regulation on the integrity and transparency of the wholesale energy market. It prohibits insider trading and market manipulation and requires reporting of transactions and inside information; REMIT II extended the duties in 2024. ACER and the Federal Network Agency supervise them.
Repowering means replacing old wind turbines at the same site with fewer but more powerful new ones. Since 2022 the Federal Immission Control Act has eased the permitting for it (section 16b BImSchG). For grid operators this changes feed-in capacity, grid connection and plant master data.
A framework for developing and deploying AI systems with consideration for ethical principles such as fairness, transparency, privacy and non-discrimination. Responsible AI goes beyond compliance: it requires proactive measures such as bias testing, explainability of decisions and clear accountability structures. In the EU context, it is increasingly becoming mandatory through the AI Act.
The metric that relates the financial return of an investment to its cost. For AI projects ROI is often hard to pin down: productivity, quality and speed gains pay off indirectly while pilot costs land immediately. Credible ROI measurement needs a clear baseline, defined use cases and honest accounting for operating, governance and change costs.
SAP IS-U is the industry-specific billing and market communication solution many German utilities run on SAP ECC. Mainstream maintenance for ECC ends on 31 December 2027; extended maintenance until 2030 costs a surcharge. The successor is S/4HANA Utilities, usually with a clean-core approach; migrations take 18 to 36 months and depend on MaKo releases and rollout.
Section 14a of the German Energy Industry Act (Energiewirtschaftsgesetz) regulates the grid-oriented control of controllable consumption devices such as heat pumps, wallboxes and battery storage. Grid operators can temporarily dim power to 4.2 kW during bottlenecks, but must grant reduced grid fees in return. Implementation requires Smart Meter Gateways, new control boxes and significant adaptations to IT systems and processes at grid operators.
The central communication unit of an intelligent metering system (iMSys) that enables secure data exchange between electricity meters, market participants and grid operators. Smart Meter Gateways must be BSI-certified and form the technical foundation for the German smart meter rollout. They are the prerequisite for time-variable tariffs, Section 14a control and the integration of decentralised energy generation.
The Solar Peak Law has applied since 25 February 2025 and amends the EEG and EnWG so that midday PV peaks do not overload the grid. New PV systems from 2 kW receive no payment at negative exchange prices, and without an intelligent metering system they may feed in at most 60 percent of their capacity. The zero payment only takes effect once a smart meter is installed. The law shifts work to the metering operator and the grid operator, not to the plant owner.
Specific Operations Risk Assessment, the EU methodology for assessing the risk of drone flights in the specific category. SORA evaluates ground and air risk and derives the safety measures required. Since 1 January 2026 new BVLOS applications in Germany must use version SORA 2.5.
A predefined operating scenario in the EU drone regulation (STS-01, STS-02) that sets approved standard conditions for drone flights in the specific category. Operators who stay within a standard scenario can declare the operation to the aviation authority instead of running an individual SORA risk analysis.
Tariff use cases are the operating modes of a smart meter gateway defined in the BSI protection profile; they determine which measurements are transmitted to whom at which resolution, for example TAF 7 for meter reading profiles in 15-minute values for dynamic tariffs and balancing, or TAF 6 for readings on demand. New gateway generations support more TAFs in parallel.
The smallest processing unit in language models, a word, word fragment or special character into which text is broken down. An English word typically consists of 1 to 2 tokens. Tokens determine both the input and output length of a model and are the basis for cost calculation when using APIs. A model's context length (e.g. 200,000 tokens) determines how much information can be processed simultaneously.
A neural network architecture introduced in 2017 that is based on the self-attention mechanism and forms the foundation of virtually all modern language models. Transformers can capture relationships between distant words in a text and can be trained in parallel. GPT, Claude, Gemini and Llama are all based on this architecture. The name of the paper: "Attention Is All You Need".
Germany's four transmission system operators, 50Hertz, Amprion, TenneT and TransnetBW, run the extra-high-voltage grid and are each responsible for one control area. They hold the frequency with balancing energy, manage the balancing groups and sign the standard balancing group contract with each balancing group responsible party. For utilities they are the counterpart in balancing, redispatch and the scenario framework for grid expansion.
The European regulatory framework for digital airspace management of drones. U-space provides services such as identification, geo-awareness and traffic information so that many drones can fly safely and automatically in the same airspace, for example along power line corridors.
Dependence on a single vendor whose products, formats or interfaces make switching technically or economically expensive. In AI, lock-in arises through proprietary models, APIs, embeddings and tooling. Countermeasures include open standards, abstraction layers, exit strategies and multi-vendor architectures that keep models and platforms interchangeable.
A software development approach where developers describe their intentions in natural language and AI generates the code. The term was coined in 2025 by Andrej Karpathy. Vibe Coding drastically lowers the entry barrier for software development and enables domain experts without deep programming skills to build functional prototypes and applications. Quality assurance remains the critical human task.
WiM governs how metering point operators switch, how devices are taken over and how meter readings reach grid operators and suppliers. It is the process basis for competitive metering and for every change of gateway administrator. For gas, a revised version applies from 2026 as WiM Gas 2.0. Whoever outsources the rollout outsources these processes too.
A security vulnerability exploited before the vendor can ship a patch, defenders have zero days of warning. Zero-day exploits are especially dangerous because neither signatures nor updates protect against them. For AI systems the attack surface additionally shifts onto models, prompts and agent tooling.
Techniques where AI models can solve tasks without (zero-shot) or with only a few (few-shot) examples. In zero-shot, the model receives only a task description; in few-shot, a few example pairs (input/output) are provided. This capability is a key advantage of large language models over traditional machine learning, which requires large labelled datasets.
LFW24 is the process, binding since 2025, under which an electricity supplier switch must be completed within 24 hours. The switch runs star-shaped via the market location ID at the grid operator instead of bilaterally between suppliers. Extension to gas and hydrogen is planned; the date is open.
