Two grid operators – One company

As Europe’s first cross-border grid operator, TenneT has been safeguarding the

security of supply in the Netherlands and large parts of Germany since 2009:

• Management, maintenance and expansion of the transmission grid

• Promoting integration of the European electricity market

• Linking up offshore wind parks to the German grid

Experiences to be taken into account:

Regulatory framework & Licenses • Balanced regulatory framework (liabilities, financing)

• Focus offshore and onshore

• Long lead times for licenses onshore

• Planned development

Technology & Industry • New technologies in HV grids

• New combinations of technologies/suppliers

• Planned development, Standardisation

• Supply chains to be built up

TenneT is Europe’s first cross-border grid

operator for electricity. With approximately

20,000 kilometres of (Extra) High Voltage

lines and 36 million end users in the Netherlands

and Germany we rank among the top five

grid operators in Europe. Our focus is to

develop a north-west European energy

market and to integrate renewable energy.
