Brouwersdam today

7

Water quality/ ecology problem today

8

Negative impact on regional economy (shell fish, tourism, …)

Water solution: restoration of tidal range

9

Integrated design of culvert (water) and tidal power plant (energy from water)

Value of culvert (water):

1. Water quality, under water/ inter tidal ecology Lake Grevelingen

2. Regional economy: shell fishery, recreation, tourism

Added value of integrated design of culvert and tidal power plant:

3. Energy transition: predictable renewable energy, CO2-emission reduction

4. Innovation: cost-effective and fish friendly capture of energy at low tidal range

5. Export potential: showcase for European industry

Opportunity: Tidal Power Plant Brouwersdam

Public reference- Culvert of 135 meter long en 40 meter wide- 15 turbines, diameter of 6 meter; 22 MW installed capacity- Energy production: 67 GWh/ year; circa 22.000 household equivalents

Water: € 105-115 million, mainly public budget required

Energy from water: additional costs +€ 75-100 million, mainly private investment/ finance required

Optimum at 25 MW for 25.000 household equivalents

Potential support from Ministry of Economic Affairs (NL) and from European Commission/ European

Investment Bank (‘blending’)50 cm of tidal range; loan 60% at 6% interest; return of investment = 7%

Energy Innovation subsidy NL,up-front

Energy exploitation subsidy NL,first 15 years

Need for additional support from e.g. European Innovation Fund, up-front or during operation

€ 6,0 mln € 0,12 per kWh € 20,8 mln

Bargain!

Roadmap2016: arranging public conditions; preparation of public procurement

2017: selection of private consortium water/ energy from water (x -> 3 -> 1)

2018-2019: project development in hybride public-private alliance, decision making on investments

2020 – 2022: construction of culvert/ tidal power plant combination

2022: start of exploitation of tidal power plant

Condition: budget for culvert/ tidal range at Lake Grevelingen in 2016

Role for European regions (and RWS)• Interconnection of sectoral policies in integral solution

• Teaming-up public and private parties in hybride alliance

• ‘Blending’, financial innovative arrangement:– Energy Innovation subsidy NL– Energy exploitation subsidiy NL– Energy Innovation subsidy EU, e.g. NER400/ Innovation Fund– EFSI guarantee and/ or loan
