Grid issues: Netherlands
Plans and Prospects
Offshore areas Several areas have been studies. Area along the coast of Holland is the most interesting.
Planned offshore windpower > 6 GW
timing 2020
Transmission System
TSOs Tennet: 380 kV, 220 kV; regional operators: ≤150 kV
Control zones and operators Tennet (entire country)
Synchronous Zone UCTE
Final electricity consumption (2002) [TWh] 99,7
Generation capacity (2002) [GW] 20,8
Peak load (2002)
Minimum load (2002)
Power Generation Portfolio [GW]
Nuclear 0,45
Thermal (non-nuclear) 19,64
Hydro 0,04
Wind 0,68
others 0,00
Offshore Power Injection
Suited Substations Beverwijk, Maasvlakte (Borssele, Eemshaven not considered)
Substation Voltage today 150 kV at Beverwijk, 380 kV at Maasvlakte
Offshore power limit 500 MW Beverwijk, 1500 MW Maasvlakte
Grid issues
Grid code requirements no requirements published, capacitor banks needed at substations, considered subject to further study
Balancing Tennet via responsible parties, with penalties
Transmission bottlenecks at injection point Beverwijk and many lines inland (380 kV)
Necessary reinforcements reinforce all congested 380 kV lines
Timing of reinforcements between 2012 and 2019
External Factors
Import/export/transit Export increases probability of congestion
other factors BritNed HVDC connector (1320 MW), NorNed HVDC connector (700 MW)
Trans Border Capacities
Offshore Cable
Connection, first projects HVAC 150 kV
Landing, first projects drilling under the dune
Best option, long term Offshore substation with one single 380 kV cable to the shore
Connection and energy pricing
Connection charges for DG deep and negotiated
Connection charges for offshore wind
Priority access for renewables
Minimum price
