  1. Introduction Matiu-Somes Island Wind and Solar Renewable Energy System Tony Pearson

  2. Introduction • Brief History of the island • Design Criteria • Chosen System • System Performance • Benefits of a combined system • Future for MatiuSomes Island

  3. History • Maori Pa or Fortress • Human Quarantine for Early Settlers • Internment camp during the world wars • Degaussing station for ships during the war • Gun defences for Wellington Harbour • Animal Quarantine Station • Nature and Scientific Reserve

  4. Power Requirements • Existing Supplies: • Unusable Cable from the Mainland • 64 kVA Generator • 36 kVA Generator • 16 kVA Generator • 3 Phase Distribution System • Requirements: • 5 Houses, 3 motel blocks, campground, Visitors centre and office block • 3 full time residents • Up to 65 short stay overnight residents • Up to 400 day trip visitors • Total load of about 25,000 kWhrs per year reducing with efficiency gains. • To Provide 11,000 kWhrs per year 65% of their predicted usage.

  18. Benefits Benefits of a combined system: Evens out the large peaks and troughs of power generation Allows for a smaller battery and generator usage Extends battery life Better match of generation and load • Follows the load profile more closely

  19. Future Further Reduce Dependency on imported fuels by: Introduction of Electric vehicles Further electrification introduction of low wattage heaters and heat pumps Conversion from gas cooking to electric Making use of hydrogen for water heating or cooking
