  1. GE Telecommunications BaseWiruca, Nicaragua Team 7: Section 12 Ricky Schaffer Mike Stanowski Adriana Philip Submitted to Dr. Colledge

  2. Table of Contents • Project Background • Ideas and Analysis • Design Specifications • Cost Analysis • Social Implications • Summary

  3. Recognizing the Need • Provide a reliable means of cell phone service to small villages such as Wiruca, Nicaragua.

  4. Defining The Problem • To find an inexpensive and environmentally friendly way of supplying power to a telecommunication system.

  5. Gantt Chart

  6. Background Information Wiruca, Nicaragua • 48 families • All are coffee growers • Earnings $100/mth/house • Disposable income of $10/mth/house • No electricity • No cell phone service, but have cell phones for use when traveling • If power were available, they would power: TV, radio, lights, fan • Current cell phone tower/system costs: $300,000-$500,000 per tower/equipment and $90,000 for the energy system to power it (solar system producing 30 kW/hr/day. (32 solar panels – each 200 W and 24 volts) • Other nearby communities recently put in a solar system for $17,000 for 200 people. • Diesel fuel is $1/liter

  7. Background Information (cont’d) • Security guard protecting each cell phone tower installation 24 hours each day. • The current protection building for the equipment is built by a subcontractor which the telecommunication firm employs. • Rated for hurricane and earthquake conditions in the country. • The community pays 1.7 Cordobas/hr for the first 25 kW-hr. They pay x Cordobas for the second 25 kW-hr. They pay y Cordobas for the third 25 kW-hr, and so on. • The generators currently employed are located inside the building for security and weather reasons. • The area is mountainous – used for growing coffee. There are micro-hydro systems located in surrounding communities. • The communities and the university are VERY interested in establishing businesses around the power generation systems. • If power lines are run from the power generation system – there MAY be regulatory concerns. Many efforts are taken to install similar systems, and if they produce less than 13.v kVolts, there are USUALLY no problems from regulators. • CLARO is the cell phone service provider.

  8. Sodium Metal Halide Battery • Lasts about 15 years (around 2500 cycles) • Temperature Range: -40⁰ C to 55 ⁰ C • It takes 7.5 hours at 150 amps to recharge the sodium metal halide battery once it has discharged (used) 80% of its energy capacity. • Temperature – 270C-350C (inside the case) • Voltage – 1.8-3.4V • Current- 20-100A • Cell power – 100-200W • Resistance (initial) – 7-10mΩ • Pressure- 1-2 atmospheres

  9. Possible Design Solutions • Required • NaMx Battery • Power Generator • Alternative Energy • Geothermal • Wind • Solar • Micro-hydro

  10. Screening Matrix

  11. Criteria

  12. Weighted Matrix

  13. Final Decision • Solar and Wind combination. • Provides most feasible option with minimum cost and maximum output.

  14. Wind Energy Specifications • Skystream Turbine (GE subsidiary) • Rated Capacity: 2.4 kW • Weight: 170 lb (77 kg) • Rotor Diameter: 12 ft (3.72 m) • Direction of Rotation: Clockwise looking upwind • Blades: 3-Fiberglass reinforced composite • Rated Speed: 50 - 325 rpm • Maximum Tip Speed: 216.5 ft/s (66 m/s) • Survival Wind Speed: 140 mph (63 m/s) • Cost: $6,212 x 3 = $18,636

  15. Solar Energy Specifications • Electrical Parameters-Optimal Power output: 225 watts-Power output tolerances: +/- 3%-Module Efficiency: 13.8%-Power Output: 38 W -Voltage at Pmax (Vmpp): 29.5 Volts-Current at Pmax (Impp): 7.63 Amps -Operating Conditions-Operating temperature: - 40 to + 90C-Max. wind load: 50 psf-Max. snow load: 113 psf-Mechanical Characteristics-Dimensions (L x W x D): 65" x 39" x 2" (1650 x 990 x 50 mm)-Weight: 43.7 lbs (19.8 kg) • Cost: $516.90 x 38= $19,976.81 + Labor

  16. Solar Panel Angle Calculations

  17. Generator Specifications • GE Product • Running Watts (W)-7000 (LP) • Surge Watts (W)-10500 (LP) • Operation-Fully Automatic • Voltage (V) 120 • Amps-58.3/29.1 (LP) • Cost: $2289

  18. Supplying the Battery With the 84 watts per square meter • Insulation • Internal Insulation (thermal and electrical) to maintain necessary internal temperature • Generator to supply needed power

  19. Additional Loads • Lighting • Three 30W Halogen CFL Bulbs • Total: 90W • GE Product • Cost: 8 x $9.31 = $74.48

  20. Hut Specifications • Houses generator and battery • Cement Walls • Fire resistant • Capable of handling various weather conditions • Cost of cement: ((15 ft x 15 ft)x2)=450sqft x $2 = $900 + (4x(15ftx8ft) x $2=$960 + (4( .5 ft x 15ft x 8ft) x $2= $480 • Total Cost = $2340 • Security • Barbed Wire Fence: $1.50 per foot • Total Fencing: 100 ft (25 ft sides around the hut) • Total Cost = $150 • Total Hut Construction Costs: $2490 + Labor

  21. Estimated Total Startup Cost • Wind System, Solar System, Generator, Lights, and Hut Construction • $43,466.29 + Labor

  22. Prototype

  23. Schematic of Telecom Base Station

  24. Time Value of Money • Diesel Power is a constant flow of cost of $1/liter. • Rate of inflation is currently 1.7% • Alternative energy is a one time large cost and some small additional maintenance costs • Diesel Power is becoming more and more expensive as alternative energy becomes less and less expensive

  25. Social Implications • Widespread use of cell phones would allow residents of Wiruca better access to areas around them for trading purposes • Eventually could move Nicaragua out of developing status and increase global competitiveness • Would increase global communication

  26. Summary • Green telecom station in Wiruca, Nicaragua. • Best option: Solar-Wind Hybrid • Estimated Total Startup Cost: $43,466.29
