Offshore Wind in Germany Lessons to be learned voor NL ir. Han van Asten, Programma manager TenneT Den Haag, KIVI NIRIA, 'Wind op Zee = Winst voor Nederland', 20 sep 2012
KIVI NIRIA Wind op Zee = Winst voor Nederland De Duitse situatie: samenwerking tussen overheid en industrie om in korte tijd zeewind op grote schaal in te voeren, de uitdagingen bij aansluitingen op het net, Lessons to be learned. Energiewende - EEG - Atomausstieg: Attractive and stable investment climate This presentation reflects on: Regulatory framework & Licensing Technology & Industry 2

TSO has obligation to connect OWF offshore Investment trigger criteria by OWF for grid connection: 1. Permits awarded 2. Construction schedule 3. Soil investigation 4. Major contracts awarded & obliging financing of wind turbines Offshore Wind Farm t Approx. 36 months Grid connection (TSO) Feed in by OWF 7
Developments regulatory framework To meet 2020 target approx. 10 bn for grid connections So far TenneT invested 6 bn TenneT (largest investor in Energiewende) 3rd party financing needed, investors are interested, Uncapped / large liabilities form significant risk (No redundancy in offshore grid connections) New legislation under construction 8
Grids connect production with consumption Grid = offshore and onshore D: onshore grid to be reinforced NL: offshore wind can be close to load 9
Licensing is complex and takes time, especially the land- & nearshore part OWF: License by BSH (Bundesamt für Schifffahrt & Hydrographie TSO: BSH, PFV (Plan Feststellung Verfahren), BimSchG, private agreements 10
Planned approach needed An offshore-tyndp seems necessary: to enable all stakeholders to build up resources, synchronise grid expansion off- and onshore And define technological standards 11
Technology & Industry, Cables and cable installation 12
High Voltage Direct Current Converters 13
Grid Connection Options for OWF Offshore AC-technology OWF DC-technology Offshore OWF OWF Filter, compensation, etc. = ~ = ~ Filter, compensation, etc. Onshore Filter, compensation, etc. Onshore = ~ = ~ Filter, compensation, etc. 14
Offshore Platforms 15
NL well positioned for offshore grid connections NL based industries active in German offshore grid connections: Cable production (land) Cable installation Platform manufacturing Platform installation Consultancy And many others for OWF 16
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 17
TenneT experience available for Dutch Offshore wind connections!!!! 18
Dank voor uw aandacht 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. Taking power further www.tennet.eu
