Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

Which connection

The electricity grid in the Netherlands consists of the national high-voltage grid and several regional grids. TenneT manages the national high-voltage grid, which transmits electricity at 110, 150, 220 or 380 kV. The regional electricity grids, with voltages of 66 kV or less, are managed by seven regional grid operators.

For connection to the Dutch electricity grid, there is a similar distribution of tasks as the one that exists for managing the grids. TenneT provides connections with power greater than (approximately) 100 MW. Connections with power less than (approximately) 100 MW are usually provided by the relevant regional grid operator (refer to the overview of their coverage areas). TenneT and the regional grid operators cooperate with each other and will jointly assist you in finding the optimum solution for you in terms of grid engineering.

Location of your connection

TenneT can advise you on the engineering feasibility (or unfeasibility) of a connection at a certain place and will provide you with a rough planning and cost estimate. The connection will generally be to the nearest high-voltage substation where capacity is available or can be created. Together with you, TenneT can examine the possibilities. Decisions about locations of wind and solar farms are the responsibility of the Ministry of Economic Affairs and Climate Policy and the regional or local authorities (i.e. the provincial or municipal authority  concerned). TenneT plays no role in these decisions.

Procedure and lead time

In the case of a new connection, TenneT will discuss the possibilities with you, and together we will explore, if necessary with the regional grid operator, what the best connection option is for your particular situation. We will then produce a technical plan for this, accompanied by an offer. After the order has been placed, TenneT will create the connection. As soon as the connection is delivered, it will be put into service. On average it takes 12 to 18 months to create a new connection to the high-voltage grid (in a situation where expansion of the grid is unnecessary). Soon the TenneT website contains more information about the steps in the connection process
