Grids − Energy interlinked


The fluctuating in-feed of power from renewable energies means that networks are subject to large loads: Originally designed for the transport and distribution of centrally generated power, they now need to be transformed into collection networks, because ever more consumers are simultaneously becoming generators.

To ensure that the customary high security of supply is not jeopardised and that voltage fluctuations remain within permitted limits, network operators require precise information on the behaviour of the decentralised feeders in relation to the network parameters. It must also be clear what maximum outputs will be in-fed, and that a system will not disrupt the network operation.

TÜV NORD supports feeders with type and project certifications, and enables them to have unobstructed, secure access to the network. With our interdisciplinary support in grid development, we offer network operators a comprehensive range of services:

When using the power of the sun to generate electricity, safety is the top concern. There are numerous standards that regulate the specifications that must be met by photovoltaic products. The "TÜV NORD type-tested" symbol gives peace of mind, guaranteeing that the requirements of the relevant product standard and the recognised technical regulations are being followed.

Biogas / Biomass

Biomass is solar energy stored in plant form. The conversion of biomass into energy is achieved using different conversion paths and technologies. TÜV NORD offers a comprehensive service package for plants that generate electricity and heat on the basis of biomass. The focus is on plants for biogas, biogas treatment and feed-in, as well as biomass plants.

Wind energy

Using wind to generate energy has been a technique used since ancient times. It ranged from simple wind wheels, wind mills throughout to sailing ships. The technology currently used focuses primarily on wind power systems with three-blade rotors in onshore and offshore facilities. With comprehensive services from a single source, TÜV NORD is dedicated nationally and internationally to this future-oriented and environmentally-friendly form of energy generation.
