Introduction● Talquin Electric is a membered own electric distribution

cooperative headquartered in Quincy Fl.● By purchasing electricity from Seminole Electric, Talquin

is able to provide electricity for 53,000 accounts, water and wastewater services from the Gulf Coast to Florida State line.

● Talquin Current system requires a substantial amount of money to deliver water to its members.

● Talquin is investing in renewable resources and noticed there is a lot of untapped potential energy in their water tank

Darius Wright-Tippins

Water Tower

● Clean water pumped and stored into tank

● Water flows out of outlet pipe to its members.

● Due to gravitational pull and height of tower can provide high pressured water.

● Water falls during peak time and refills throughout day.

Darius Wright-Tippins

● The aim of this project is to design a Hybrid Hydro-Solar water tower energy storage system

● Talquin current system requires substantial amount of money to provide members with water services.

● Talquin water department bill is currently high.

Problem

Darius Wright-Tippins

Cost($/Month) = E(kWh/Month) × Cost(cent/kWh)Talquin pay

11 cents/kWh

Darius Wright-Tippins

● Offset the department bill● Harness the potential/Kinetic Energy for a later

usage● On-grid without batteries. This a simple and

efficient system that sends any surplus energy back into the grid to be credited for use at other times.

Solution

Big Scale Calculations

Power (24 Hours)= 2.5kWSaving = (0.11 *2.5) = $0.275/Day

Small Scale Model

Darius Wright-Tippins

Small Scale Components

● 1 units of 1 inch brass Check Valve● Wayne ½ HP shallow well system

with 8.5 gallon tank

● 15 gallon reservoir● Water Buddy Turbine generator ● Pressure gauge● Pressure tank● 24 volt Inverter ● Water tube

Darius Wright-Tippins

Pressure Tanks● Allows water system to work on

demand (similar to water tower)● Allows water to move at a pressure of

50psi● Pressure switch is set between 30-50

psi ● As water fills tank, compressing air to

max psi the pump cuts off. If pressure is below 30 psi, pump turns on.

Darius Wright-Tippins

● ½ HP max flow rate = 420 GPH 7 GPM at 50 psi

● Dual Voltage, operates at 115V/230V, 8 A / 4 A, high efficiency square flange motor

● Pressure switch pre set for 30-50 psi for automatic operation

● Start current is about 25 Amps

Wayne ½ HP shallow well system with 8.5 gallon tank

Water Buddy Turbine Generator● Generates DC

Power● 12/24 V

capabilities● Adaptable to

various nozzle sizes

● Lightweight and ideal for small scale model

Challenges

● Wetting of electrical components ● Stabilizing of pressure in tank to rotate

blades of turbine● Creating a design easy to assemble and

disassemble● Not generating a significant amount of

electricity ● Inverter Malfunctioning● Wiring is incorrect

Prediction And Recommendations● Design 3 KWac PV System to deliver 6000 KWh/year

● Utility Cost of $0.11/KWh

● Assume $4.5/ Wac

● Cost of the System: $27,000

● Balance paid: 6% for 30 years

● Combine Federal Tax and State Tax: 37%

Komlan Amesse

● The net cost of the system after the rebate

P = $27,000 − $4.50/W× 3000 W = $13,500

● The annual loan payment: 0.07265/yr × $13,500 = $980.78● Tax savings = 0.06 × $13,500 × 0.37 = $299.70

● Cost of electricity = ($980.78 − $299.70/yr)/6000 kWh/yr = $0.1135/kWh

● Net Benefit = 6000 kWh/yr × (0.12 − 0.1135)$/kWh = $39/yr● Net Benefit after 30 years = $ 1304
