Presentation Summary

• State Energy Office Programs
• Area DNR Renewable Energy Projects
• Community-Based Anaerobic Digestion
• GIS AD Asset Mapping Tool Demonstration

DNR State Energy Office

• U.S. DOE designated energy office for Iowa
• Non-regulatory
• Support EE/RE implementation in public facilities
• Provide EE/RE outreach and education to Iowa
  Communities
• IEO Mission Statement
• The mission of the Iowa Energy Office is to
  increase the use of energy efficiency and
  renewable energy technologies while ensuring the
  reliability of the states power.

Iowa Energy Bank

• Energy management program for school districts,
  local governments, hospitals, non-profit
  organizations, and private colleges
• Uses state resources and private sector money to
  help facilities achieve energy and money savings
• MOA to join the program
• Technical Engineering Analysis (TEA)
• Six-month interest free loan for TEA
• Savings generated repay the loan

5
SIFIC

• State of Iowa Facilities Improvement Corporation
• Finance energy management improvements in state
  agency facilities
• Reduce state spending by making state government
• more energy efficient
• Save state dollars once the cost of implementing
  the improvements has been recouped through energy
  cost savings

6
Iowa Clean Cities Coalition

• Expand infrastructure for alternative fuels and
  vehicles
• Develop and implement idle reduction and fuel
  economy strategies in the state
• Reduce our consumption of petroleum and improve
  air quality in the state
• Encourage public-private partnerships

New Bohemia Solar Project

• Collaboration between I-RENEW, Alliant Energy,
  the City of Cedar Rapids, the Thorland Co., and
  DNR funded by US DOE
• 7,200 watts of solar-generated electricity for
  Alliant Energys Second Nature customers
• Kouba Building, Cedar Rapids New Bohemia
  Brownfields Redevelopment neighborhood

EE Fort Dodge Home

• Collaboration between Iowa Central Community
  College carpentry program, RDG Planning and
  Design, and the DNR funded by 100,000 US DOE
  Rebuild America Program grant
• 1,780 square feet total production cost
  180,000
• Uses 60 64 percent less energy than a similar
  home
• Energy efficient envelope, ground source heat
  pump, high efficiency windows, daylighting,
  Energy Star appliances, on-demand water heater,
  and landscaping that minimize watering needs

9
G.A.P.R.I.

• Grinnell Area Petroleum Reduction Initiative
• Reduce community dependence on petroleum by
  increasing the use and procurement of
  bio-products
• Collaboration between Imagine Grinnell and Iowa
  DNR Energy funded by U.S. DOE

10
Farm Bill 9006 Assistance

• DNR Energy is part of USDAs Section 9006 RE/EE
  grant assistance team
• Provide letters of support to all Iowa applicants
  and grant writing assistance
• Iowa received 51 of the 375 grants awarded this
  year, second highest in the nation
• Iowa received 8 of 12 combination grant /
  guaranteed loan awards
• Amana Farms was awarded a 500,000 grant and a
  1,068,500 guaranteed loan for their digester
  project

11
Waste Streams to Commodities

• Economic development opportunity to
• Process manure and other organic
• waste streams to
• Produce biogas and associated
• value-added products from a
• community-based anaerobic digester

12
AD Community Outreach

• Since June 2005, DNR has worked with 16 Iowa
  communities to investigate AD opportunities

13
Community Digester Basics

• Anaerobic digestion is the bacterial
  decomposition of organic matter that occurs in
  the absence of oxygen

14
Why Large-Scale, Co-Digestion AD?

• Co-digestion of multiple, organic
• feedstock for better gas production
• Large-scale 300 1,000 tons
• feedstock/day
• Produces large volumes of renewable
• energy, making that energy more marketable
• Relieves smaller livestock producers from
  digester operation and management
• Provides rural economic development and
  investment opportunities

Iowa Methane Potential
Iowa Potential 677,000 MWh/yr could power
63,469 average American homes, offsetting
47,390,000/yr in retail electricity (_at_ 0.07/kWh)

Project Design Models

• Farm scale large dairies 750
• Community-based, with centralized
• organics collection
• Food and Energy Enterprise Zones
• possibly where the greatest
• opportunities lie
• Integration with community
• wastewater treatment facilities
• Industrial park model, where industries
• with problematic waste streams build
• and use a digester collectively

21
Economic Benefits

• Community economic development businesses,
• jobs, local tax receipts, green energy
  investment opportunities
• Renewable energy biogas and/or electricity
  thermal
• Minimized wastewater treatment costs and tipping
  fees
• High value crop nutrients measurable, more
  environmentally benign
• Solids separation soil amendments and/or
• livestock bedding
• Carbon credits, tradable on the Chicago Climate
  Exchange

22
Environmental Benefits

• Reduces odors by 90 percent
• or more
• Reduces GHG damage to
• the atmosphere CO2 X 21 CH4
• Reduces nitrate pollution to water
• from faster nutrient uptake
• Renewable fuel that reduces fossil fuel use and
  emissions associated with their use
• Source Danish Agricultural Advisory Service,
  Crop Production (15-year study)

23
Societal Benefits

• Addresses quality-of-life issues
• Promotes positive environmental
• stewardship
• Improves communitys perception of industry
• Makes livestock, food, and energy production
  sustainable in the community

24
DNR Assistance to Communities

• Organize core working group
• Develop and present community meetings
• Assemble and participate in advisory committees
• Identify project funding sources and incentives
• Identify technology providers
• Enlist contractor to complete financial and
  technical feasibility study
• Provide guidance for project permitting
  requirements
