Nigeria Solar and BESS Cost Estimate.ppt
- 1. Benefits of the Solar / BESS • Solar – Pollution Free and No Greenhouse Gasses – Reduced Dependency on Oil and other Fossil Fuels – Can save for use by Nigeria Thermal Units – Renewable Clean Power – Every Day – Even Cloudy days • Battery Energy Storage Systems – Speeding up the replacement of Fossil Fuels – Less dependent on Electrical Grid – Match Perfectly with Solar Systems – Great to match supply with demand – Great when sun isn’t shining (night) and wind isn’t blowing
- 2. Basis of BESS Estimate • Assume 3.84 GW / 15.36 GWhr • Need – Civil – Foundations – Materials – Controls – Battery Management – Metering – Compartment Cooling – Substation Interconnection – Transformers – Fire Protection • Engineering – Preliminary Design, Detailed Design • Construction • Commissioning • Training 3 Battery Modules - Backs Exposed
- 3. Basis of BESS Estimate • US Market - $1500-1700 / kW • Assume $1600 • $6.144 B 2 Rows of Batteries Racks – Top and Bottom (2 of Many)
- 4. Basis of Solar Estimate • Assume 60 sq miles of land (buildable) • 38,400 acres of land • Assume 50 MW / 500 Acres = 1 MW / 10 acres • 3,840 MW (3.84 GW) of buildable solar • Assume 300 solar panels / acre • 11,520,000 solar panels total • Still require: – Infrastructure – Substation, Transformers, Inverters, Cabling, Weather Station, Switchgear, Control and Communications – Engineering Support – Civil Site Prep, concrete, steel – SCADA – Engineering – Preliminary Design, Detailed Design – Construction – Commissioning – Training Solar Panels – 300 panels per Acre
- 5. Basis of Solar Estimate • Cost – Ranges between $1000 - $3000 (US Market) – Assume $2000 / kw installed • 3,840,000 kw • $7.68 B • Note, most projects are smaller. 75-100 MW range and smaller. • Probably would phase in with a number of smaller programs in lieu of all 3.84 GW One of Several Weather Stations
- 6. Other Required Infrastructure • BESS – Civil / Structural – HVAC – Fire Protection – Power Conversion – Fire Detection (VESDA) • Solar – Substation – HV Switchgear – Cabling – Weather Stations – Controls and Communication Inverter and Transformer shown, HVAC Chiller units behind (see ducts into building)
