TÜV NORD provides transparency in complex energy systems through time-resolved simulations, transparent scenario comparisons, and robust performance metrics for generation, storage, grid integration, and cross-sector energy supply concepts.

The energy market is undergoing fundamental change: the share of variable generation is increasing, flexibility requirements are rising, and the sectors of electricity, heat, industry, and mobility are increasingly being planned and operated in an integrated manner. As a result, time-dependent interactions determine technical feasibility and economic viability – including load profiles, generation profiles, storage states, operating limits, availabilities, as well as market and grid signals.
Energy flow simulation makes precisely these effects visible. Over the entire time horizon, it shows how power flows move through the system, where bottlenecks arise, which operating modes are realistic, and how parameters behave under real load and generation profiles during operation. This provides a robust basis for system design, operation, and investment decisions – today and with a view to the future.
TÜV NORD models and simulates grid-connected systems as well as island systems using internationally established simulation software for cross-sector energy systems. Depending on the specific question, we analyse time horizons of up to one year – with temporal resolutions ranging from one minute to one hour.
Based on your project data (such as load curves, energy demand, generation profiles, operating limits, and investment and operating costs), we analyse system variants, evaluate technical and economic performance indicators, and identify specific optimisation needs – from system configuration to operating strategy. The model boundaries and assumptions are documented transparently to ensure that results can be clearly interpreted and effectively used in project decision-making.
Our energy balance analysis provides a comprehensive, time-resolved analysis of your energy system. We account for energy inputs and outputs, storage states, as well as costs and revenues over defined time periods.
Based on real operational data – such as load curves, consumption profiles, and local renewable generation – we determine the actual energy demand and identify concrete efficiency and savings potentials. In addition, as part of potential analyses, we assess how existing or additional technologies can be optimally integrated.
With detailed energy flow simulations, we support you in the technical and economic optimisation of your energy system. Based on your project data – such as load curves, consumption data, energy yields, as well as CAPEX and OPEX parameters – we analyse system variants and determine the optimal operating strategy.
The objective is the maximisation of revenues through the efficient operation of battery storage systems, electrolysers, and renewable energy generators.
With our sensitivity and scenario analyses, you gain a robust basis for decision-making for the planning and further development of your energy system. We systematically analyse the influence of relevant variables – such as the volatility of renewable energy, price developments, or technical parameters – over the course of the year.
This makes efficiency measures visible and enables transparent comparison of different future scenarios.
Depending on the specific question, we analyse time horizons of several years over the project lifetime. The temporal resolution is selected on a project-specific basis (e.g. from minute- to hourly values).
Cross-sector energy supply concepts such as grid-connected systems as well as island systems with generation, conversion, and consumption. The specific scope is defined during the initial consultation.
System boundaries, input data, constraints, and calculation logic are documented transparently so that results are traceable and verifiable.
Yes, depending on the project, we evaluate technical and economic performance indicators and compare system variants based on defined cost and revenue assumptions.
Through sensitivity and scenario analyses, we make the effects of key assumptions transparent and derive robust recommendations.
TÜV NORD stands for independent, neutral assessment and technically sound system analysis. We document model boundaries and assumptions transparently, make system variants robustly comparable, and derive actionable recommendations. This ensures verifiability and decision confidence in complex, cross-sector energy systems.
