  1. GE Project Abel Danny Glaser Derek Tafel XingYun Wang

  2. Table of Contents • Recognize the Need • Defining the Problem • Design Ideas • Matrices • Calculations/Payback • Model

  3. Objective • To design a secure and sustainable hut to power a no grid telecom base station in Wiruca, Nicaragua • Find the best/efficient renewable energy resources available as the main power source • Payback period of 1-3 years

  4. Define Problem • No energy grid in Wiruca • low disposable income • Weather and environmental problems • Heat and ventilation inside the hut

  5. Requirements • Sodium metal halide (NaMx) battery • A constant power of 1.2 Kw is needed to power the telecom base • BTS DC equipment will operate at -48 VDC • Components that supplies the power needs to come from DC generator, renewable resources or NaMx battery

  6. Customer needs assessment • The community and the university welcomes electricity being supplied to them • No electricity, no cell phone service, but they use cell phones when they travel • They would power TV, radio, lights, fan if power were available • The area is mountainous

  7. Customer needs assessment • 48 coffee growing families • Each house earn $100/month with $10 disposable income • Diesel fuel costs $1/liter • The community pays 1.7 Cordobas/hror $0.08/hr for the first 25 kW-hr. • x C$for the second 25 kW-hr and y C$for the third 25 kW-hr, and so on

  8. Community information • Currently a cell phone tower/system costs: $300000 - $500000 • Each cell phone tower has a security guard 24/7 • The telecommunications firm employs a subcontractor to build the protection buildings for the equipment's • Cell phone service provider is CLARO

  9. Background information • There are several ways we can provide power • Diesel Driven DC Generator Set Use diesel as fuel to create electricity • Alternative energy resources Utilize the available renewable energy resources (wind, solar, hydro, geothermal, etc) in Wiruca to create electricity • NaMx battery

  11. Design ideas • Our design is a combination of two of the following power sources: • Solar Power • Hydro Power • Geothermal • Wind • Diesel Generator • We also had to come up with an idea how to control the temperature in the hut.

  13. Weighted Matrix

  14. Solution • We chose solar and diesel generator to provide power • For heat problem inside the hut, an air conditioner will be used to maintain the room temperature that is optimum for the components. • The telecom company will hire a subcontractor to build everything as well as other personnel to maintain the hut

  15. Energy Source: Diesel • For considering diesel power as a renewable energy source we recommend using the 2.1kW diesel generator produced by Draper • Some notable specifications: • This generator, powered by a 4.8hp Lombardini diesel engine is in expert quality and features the smallest EU noise complaint. • Currently cost $2,611.52.

  16. Solar radiation

  17. Comparison of solar panels BP GE SUNTECH YING LI SOLAR

  18. Energy Source: Solar Panel • General Electrics 200W solar panel • Wewouldneed 32 sonar panels in order to produce 6.4kW of power • Dimensions: 58.5" x 38.6" x 2.2«  • Cost $700

  19. Calculations

  20. Calculations and Payback • Initial cost= $25,160.00 • Possible price of fuel over a year = $370.97 • A 0.0186kW industrial fan uses 162.93kWh if running year round • If using 2 .015kW bulbs for 510 hours uses 15.6 kWh • We will use any excess energy for the community to recharge their cell phone batteries. we can charge $.02 or .5 cordobas • In a month if we assume that they recharge once a week there should be a profit of $3.84 • GE will have to make $729.80 a month to have a payback period of 3 years
