UN DESA Tom Hamlin Inter-Regional Adviser on Energy and Transport Division for Sustainable Development
Deep penetration of renewables • Technical and Financial Assessment of Wind, Solar and Pumped Hydro Energy Storage • Pilot stage ~1.5 MW, SCADA on generation and test of Reverse Osmosis load modulation • Scale-up Full Feasibility Study ~13.5 MW wind, ~2 MW photovoltaic, 10 MWh@10 MW pumped hydro energy storage for 30% renewable power capacity, 15% renewable electricity production
Wind Atlas, Assessment, and Application Program (WAsP) Freetown
Pilot Phase • ~1.5 MW wind power installed • 6 or 7 midsize turbines (Vergnet or WES type) • Hurricane preparedness • 70 ton or smaller crane (on island) • Feed-in to the 11kV lines with small SCADA controlled substations/ transformers • SCADA generation upgrade with ability to modulate power consumption by reverse osmosis plants
Financial Scenario for Pilot 1.5MW RETScreen
Scale up Assessment • Breaking the 15% barrier • Power quality • Reducing Spinning reserve losses • Making Renewables into firm power Feasibility for scale up takes place during the GEF pilot but is an indirect project impact
Single Turbine change of > 80% power -A&B Meteorological Service
To avoid simultaneous power loss when scaling up to ~30% intermittent renewables ~15 MW- Diversify wind power to Crabbs, Freetown and McNish- Use wind and distributed solar PV- If still needed add Flywheel bridging power ( 20 seconds)
Pumped Hydro Energy StoragePumping, Generating and State of Storage
Project Phase Next Steps • Site measurements correlated to GIZ data 3-6 months • EIA new sites for wind • Pilot wind project tendering process • SCADA upgrade/ RO plant modulation test • Power Purchase Agreement and Build Own Transfer (or equivalent) • Pilot Wind Demos (3 sites) • Full feasibility for post project scale up
