In the world of Renewable energies, You will come across many specialised terms, technical abbreviations and regulatory terms in network planning and project management. In our glossary you will find compact and comprehensible explanations of the most important terms - practical and to the point.
Period in which the investment costs of a system are offset by savings or income.
Proof of the technical grid suitability of a generation system (e.g. PV system), required for certain grid connection capacities in accordance with VDE guidelines.
Electrical power that flows back and forth between the grid and the generation system without being converted into usable energy - important for grid stability.
German regulatory authority for electricity and gas, among other things. Responsible for market monitoring, grid regulation and the market master data register.
Tradable emission rights that companies use to offset or regulate CO₂ emissions. There are mandatory and voluntary markets.
Central law for the promotion of renewable energies in Germany. Regulates feed-in tariffs, subsidy models and grid connections, among other things.
Direct utilisation of self-generated electricity (e.g. from PV systems) in your own business - particularly attractive from an economic point of view.
Support in selecting and applying for state funding programmes for systems, storage or hydrogen systems.
Storage systems (e.g. battery, Hydrogen- or heat storage systems) with high capacity, used for load shifting, grid stabilisation or optimising self-consumption.
Combination of different energy generation or storage systems (e.g. PV + storage + heat pump) to form an integrated overall system.
Central register of the Federal Network Agency for recording all electricity generation plants in Germany - mandatory registration for operators.
Technical and legal connection of a generation plant to the public electricity grid - includes planning, authorisation and Realisation.
Technology for converting sunlight into electrical energy - key technology for decentralised energy generation Energy transition.
Planning and preparation of a project (e.g. PV or Wind turbine) until the project is ready for realisation - including site selection, economic viability, approvals.
Networking of the electricity, heating, mobility and Industry to optimise the use of renewable energies and increase efficiency.
Hydrogen produced using renewable energies is regarded as a key element for climate-neutral industrial processes and mobility.
Utilisation of the kinetic energy of the wind to generate electricity via wind turbines - particularly effective for large-scale use.
Plan for measuring and billing electricity generated, consumed and fed into the grid - essential for self-consumption, subsidies and grid utilisation.
