 Design a telecom cell phone base station that uses sustainable energy sources, a diesel generator system, and sodium metal halide batteries to optimize green power used to run a base station.  The system should optimize available power in areas with either no energy grid or a highly unreliable one. *GE Hand-Out PROJECT OBJECTIVE

 We recognize the need to develop an easily implemented telecom base station that utilizes renewable energy. RECOGNIZING THE NEED

 Our issue stems from the unreliable grid  What sources of renewable energy will we use  To what extent will we rely on what source THE PROBLEM AT HAND

 1.2 Kilowatt load  Implementation of GE’s Sodium Metal Halide Battery  No access to the grid  Renewable energy sources DESIGN SPECIFICATIONS

 48 families  Occupation: Coffee Farmers  Region is Mountainous  12 hours of sunlight on average GAINING INSIGHT: WIRUCA, NICARAGUA

 Sodium Metal Halide Battery  New battery made by GE  32 kwh effective capacity  Charging efficiency: 97%  Discharging efficiency: 92%  Solar Systems  6 kw system  Priced around $35,000  Converts the Sun’s UV rays into energy  High startup cost  Low running cost SOURCES OF POWER

 Wind turbines  Converts wind into energy  High startup cost  Low running cost  Generator  Converts a fuel into energy  Low startup cost  High running cost SOURCES OF POWER

 Solar only  Unreliable  Wind only  Unreliable  Solar and Wind only  Too expensive to make reliable  Solar, Wind, and Generator  High cost  Solar and Generator only  Good output for the cost  Wind and Generator  High running cost CONCEPT GENERATION

SKETCHES

 Solar and Generator  6 kw system  Charges batteries during the daylight hours  Generator runs when the solar system and battery are unable to sustain 1.2kw load FINAL DESIGN

 6 kw solar system  Price ~ $35,000  Provides 90% of the power  Generator  Runs ~ 1,306 hours  Uses 156 gal  Sustaining cost ~ $590 per year  Money saved  Over 10 years the telecom centers can save over $20,000  Over 20 years the telecom centers can save over $65,000 COST ANALYSIS

COMPLETED DESIGN

 We decided to use a 6 kw solar system and a generator  A telecommunications base station  Use of alternative energy  Utilizing the GE Battery SUMMARY
