Problem Statement

  • Chinery acreage power outages
  • Alternative energy systems

– Wind – Solar – Storage

  • Projections

– Energy use – Energy production – Future building plans(from Professor Patterson)

  • Economic analysis of each system
  • Determine mode of operation for alternative

energy system

Problem Statement

  • Other Cost Savings

– Geothermal – Heat pumps – Insulation – House modifications – Unconventional possibilities

Users and Uses

  • Chinery family and Professor

Patterson

  • Provide electrical power, heat,

cost savings, more reliability

  • Provide economic analysis for

possible systems

  • With the design, Chinery’s will be

able to chose the system that best fits their needs

General Solution Approach

  • Research all alternative energy

system possibilities

  • Gather information of Chinery

farm (power use, wind data, solar data)

  • Use data to size the possible

system (production, storage)

  • Perform economic analysis of

each system to test usability

General Solution Approach

  • Design/research possible

modifications or additions to save money and/or power

  • Research turnkey systems and

compare

  • Research all aid and grants available
  • Research all regulations, permitting

requirements, and codes

Modes of Operation

Possible modes of operation

– Stand alone – Grid connected with no storage – Grid connected with storage – Storage only – No change

  • Net metering
  • Recommend the best system based on

an economic analysis and energy production

Solar

  • Iowa Energy Center data
  • Photovoltaic vs. solar thermal
  • Roof vs. ground mount

– Tracking the sun – Tilt of the panels

  • Used to supplement energy from

wind

– Cost of solar energy ~ $0.18/kWh

  • Performance degradation

Modeling the System

  • Energy demand

– Monthly – Weekly

  • Energy supply from solar

– Solar energy data – Solar panel area – Tracking

  • Energy supply from wind

– Wind energy data – Rotor diameter – Tower height – Wind turbine efficiency

Permitting

  • City of Ames website
  • Story County website
  • American Wind Energy

Association (AWEA)

  • Assisted by contractor

AWEA Model Zoning Ordinance

  • Tower Height
  • Set Back
  • Noise
  • Approved Wind Turbines
  • Compliance with Uniform Building Code
  • Compliance with FAA regulations
  • Compliance with National Electric Code
  • Utility Notification

Subsidies and Tax Incentives

  • Ames/Story County special tax

assessment of wind energy equipment

  • State property tax exemption—wind &

solar

  • Iowa Code § 422.45—no state tax on

total cost of wind energy system

  • 20 year, zero interest loan through the

Iowa Energy Center

  • Solar property tax incentive

Geothermal

  • Closed Loop

– Horizontal – Vertical

  • Limited space applications
  • 150-250 ft. depth

– Slinky

  • Open Loop

– Mineral build-up – Waste water uses

Heat Pump & Related Incentives

Air Source Heat Pumps Supplemental heating required at low temperatures Midland Coop incentives

– Rebates

  • $350/ton (geothermal)
  • $150/ton (air-to-air)

– Heat rate

  • $0.0387/kWh October-May
  • $0.0685/kWh June-September

Additional Energy Savings

  • Uses for excess wind generation

– Pumping water – Electric water heater

  • 50-gallon Marathon $220
  • 85-gallon Marathon $220
  • 105-gallon Marathon $275
  • Increasing efficiency of house

– New windows – Drain heat recovery system – More insulation

  • Currently no insulation in some areas

Energy Storage

Use as a buffer between supply and demand Optimize size of storage based on economic analysis and energy usage compared to energy supply

  • Batteries

– Lead Acid – Gel

  • Pumped Storage

– Old water tower – ~90% efficient

Energy Storage

  • Flywheel

– Long Lifespan – Low maintenance

Economic Analysis

  • Cost of no alternative energy

system

  • Total costs/savings from

alternative energy systems
