Seychelles Public Utility Corporation: renewable energy integration into the grid

  1. 1. Public Utilities Corporation Renewable energy integration into the grid
  2. 2. Our Mission Presentation for GCF 2 We are responsible for: • The generation, transmission, distribution and sale of electrical energy • The treatment of raw water and supply of potable water • The treatment and safe disposal of waste water into the environment
  3. 3. At a glance • Parastatal company created in 1986. • Headquarters in Roche Caiman, Mahe, Seychelles. • 1,040 employees Presentation for GCF 3
  4. 4. At a glance • 35,000 electricity, 29,000 water and 4,500 sewage customers • 378 GWh produced (2015) • 6.8 GWh from wind • 1.3 GWh from distributed rooftop solar • 8.5 million m3 of water distributed (2015) • Turnover SCR 1.4 billion Presentation for GCF 4
  5. 5. Key Assets • La Gogue Dam • Storage capacity – 970,000 m3 • Rochon Dam • Storage capacity – 50,000 m3 • Desalination plants • Total production capacity 24,000 m3/day Presentation for GCF 5
  6. 6. Key Assets • Victoria Power Station B • 11.5 MW capacity • Victoria Power Station C • 74 MW capacity • Praslin Power Station • 16.3 MW capacity • 6 MW Port Victoria Windfarm • 1,500km low voltage distribution lines • 185 km 11kV overhead, 70 km 11kV underground Presentation for GCF 6
  7. 7. Renewable Energy Integration • Grid Studies Conducted (Energynautics and Okinawa Enetech) • Grid impact assessment – how the introduction of RE sources will affect the grid performance • Dynamic Stability • RE sources are intermittent power sources • It is important to ensure that alternative dispatchable power sources are available to meet the Load Demand at all times Presentation for GCF 7
  8. 8. Dump load test – Okinawa Enetech • 4MW load on a generator. • Disconnect the generator. • How does the system react? Presentation for GCF 8
  9. 9. Renewable Energy Integration - Generation • Immediate - ensure sufficient Spinning Reserve is available by increasing generator capacity if necessary • Short-term – possible introduction of adequate Battery Storage within 3 years Presentation for GCF 9
  10. 10. Transmission and Distribution • Voltage Profile should be maintained within acceptable limits Presentation for GCF 10
  11. 11. • 33 kV South Mahe network extension • Will also have 2 routes to the Anse Boileau Substation. Presentation for GCF 11 Transmission and Distribution
