Equity Metrics and Workforce DevelopmentList All
The Energy Efficiency and Conservation Pillar of the State Energy Plan objective is as follows: Encourage the expansion and diversification of energy resources, incentives, and programs. The strategy includes the following goals: Support Energy Efficiency Efforts in Underserved Areas; Low Income Housing Tax Credit; Connect and Leverage Iowa’s Energy Assistance Programs; and Heating Fuel Assistance.
The State Energy Plan has four pillars, one of which is Economic Development and Energy Careers. The objective of this pillar is to Increase the local talent pool for energy-related careers while promoting employment and training opportunities in the energy sector. There are two goals under the objective: Accelerate and Elevate Energy Sector Partnership Efforts; and Build Robust Career Pathways to High-Demand Occupational Needs. In an effort to prepare for a shrinking energy workforce with a growing energy demand, the Iowa Energy Workforce Consortium was organized by Iowa utilities with the purpose of bringing industry experts together to discuss and collaborate. To capture the full scope of the industry and utilize all parties that make up the workforce pipeline, the consortium also asked state agencies and community colleges to be a part of the discussion. These stakeholders meet regularly so they can continue to evolve with the changing workforce and keep a pulse on the needs of the industry.

Public Building Requirements List All
All public buildings are required to comply with the 2012 IECC code.
Iowa Code requires an LCCA review of the energy equipment installed in a public building in the following cases: The Code of Iowa requires “… a public agency responsible for the construction or renovation of a facility shall… include as a design criterion the requirement that a life cycle cost analysis be conducted for the facility.” The LCCA requirements promote energy efficiency in public buildings by accounting for reduced operational costs for energy efficient systems. The guidelines for the analytical procedures that comprise the review were updated in 2018.
Iowa continues Phase III of its public building benchmarking database (B3). The Iowa Energy Office provides B3 users with opportunities for peer collaboration, one-on-one training, and technical support to assist in data entry and in the development of presentations to demonstrate reduction of energy usage in public buildings. Users are able to benchmark their data, track their energy use, and identify buildings for energy efficiency projects that show high potential for energy savings and Return on Investment.

The Iowa Energy Center strives to advance efficiency and renewable energy within the state through research and development while providing a model for the state to decrease its dependence on imported fuels. In late 2017, administration of the Iowa Energy Center program was transferred to the state energy office at Iowa Economic Development Authority. The Iowa Energy Center receives its funding from an annual assessment on the gross intrastate revenues of all gas and electric utilities in Iowa. The Center has historically offered a Competitive Grant Program that awards funds to Iowa-based nonprofit groups to conduct energy-related research, demonstration, and education projects. Projects under this program ranged in size and complexity and were conducted throughout the state by researchers at Iowa’s major universities, colleges, community colleges, and at nonprofit energy organizations and community-based educational groups. The program is currently undergoing revision and will resume sponsoring eligible projects in mid-2018. The legislative-defined mission of the Iowa Energy Center at the Iowa Economic Development Authority is to support implementation activities of the Iowa Energy Plan, of which energy efficiency was one of the four foundational pillars.
The state also partners with private companies for research and development of energy-efficient technologies through the Iowa Economic Development Authority (IEDA). IEDA offers a variety of programs to Iowa businesses for energy efficiency-related research and development investment. These programs include a research activities credit program, a Demonstration Fund program, and the Iowa Innovation Acceleration Fund. Through IEDA, Iowa supports $2 million in research activities in small and medium-sized companies as well as technology transfer and commercialization efforts.
The University of Northern Iowa's Center for Energy and Environmental Education (CEEE) helps children, youth, and adults make sense of complex environmental and energy-related issues while finding ways for the community to participate in positive, solution-oriented responses. The CEEE creates opportunities for UNI students and faculty to take leadership roles in creating more sustainable communities, and brings diverse stakeholders together to find common ground while working to solve problems.

CHP
CHP Summary List All
Iowa has an interconnection standard that applies to CHP, but otherwise has limited policies to encourage CHP. No new CHP systems were installed in 2018.
Interconnection StandardsList All
Policy: Iowa Interconnection Standard
Description: In Iowa, rate regulated utilities include only the state's two investor-owned utilities, MidAmerican Energy and Interstate Power and Light (IPL), and Linn County Rural Electric Cooperative. Iowa's detailed interconnection standards apply to distributed generation facilities of up to 10 megawatts (MW). The definition of a distributed generation facility includes qualifying facilities (QFs) under PURPA and alternative energy production (AEP) facilities as defined by Iowa law. The rules are contained in IAC § 199-45 adopted by the IUB in January 2017. Like many recent interconnection regulation adoptions in other states, the Iowa rules set four levels of review for interconnection requests.

Additional Supportive PoliciesList All
Some additional supportive policies exist to encourage CHP. Iowa was a participant in the National Governors' Association Policy Academy on CHP in 2012, which resulted in a CHP technical assistance program though the Iowa State Energy Office. Activities include targeted outreach events, workshops, presentations, and the development of a CHP resource guide. The Combined Heat and Power Resource Guide for Iowa provides permitting guidance, a contact directory, summary of financial incentives, and links to additional resources.
The Iowa Economic Development Authority has funded the development of Iowa Biogas Assessment Model, which is a tool that can be useful in developing CHP projects by identifying opportunities for biogas fuel inputs. With an abundance of biomass in the state, using biogas as a CHP feedstock may make the economics of certain projects more attractive.
Iowa code 567 IAC 22.1(2) allows permitting exceptions for some CHP systems, including natural gas-fired units less than 10 mmBTU/hr and units less than 1 mmBtu/hr powered by coal, fuel oil, untreated wood, untreated seeds or pellets, or other untreated vegetative materials.

Utilities
Score: 4 out of 20
Utilities Summary List All
Iowa's utilities administer energy efficiency programs under a regulated structure with oversight by the Iowa Utilities Board (IUB) and significant input from the Office of Consumer Advocate. Iowa Code 476.6.16 mandates that electric and natural gas utilities that are required to be rate-regulated (investor-owned utilities or IOUs) must offer cost-effective energy efficiency programs. Energy efficiency plans filed by municipal utilities and electric cooperatives include voluntary goals. The utilities recover program costs of the plans approved by the IUB through tariff riders on customer bills.
Iowa's utilities have long records of funding and providing comprehensive portfolios of energy efficiency programs to all major customer categories: residential, commercial, industrial and agricultural. Funding levels have been strong throughout the years, with a notable decrease in the late 1990s as the state considered restructuring proposals. Since the early 2000s, the state has renewed and increased its commitment to energy efficiency programs. However, in July 2018, utilities filed new plans with savings 25-50% lower than in the prior period and a bill signed on May 4, 2018 allows customers to request an exemption from electric energy efficiency plans if the electric utility's RIM test is less than one.
The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Customer Energy Efficiency Programs List All
Iowa's energy utilities administer energy efficiency programs for their customers. State law requires regulated utilities to provide such programs. Most publicly owned utilities in Iowa (municipal utilities), as well as rural electric cooperatives, provide energy efficiency programs, ensuring nearly statewide coverage.
Regulated investor-owned utilities recover costs of programs approved by the Iowa Utilities Board via adding tariff riders to customer bills. This is an automatic rate pass-through, reconciled annually to prevent over-recovery or under-recovery. The IUB is authorized to conduct prudence reviews of IOU energy efficiency and may disallow imprudent costs.

Evaluation, Measurement, & Verification List All
-
Primary cost-effectiveness test(s) used: societal cost test
-
Secondary cost-effectiveness test(s) used: utility cost test, participant cost test, ratepayer impact measure cost test, and total resource cost test
The evaluation of ratepayer-funded energy efficiency programs in Iowa relies on regulatory orders (Iowa Administrative Code 199—35.5(2) (f)(476)). Evaluations are administered by the utilities. There are no specific legal requirements for these evaluations in Iowa. Evaluations are conducted statewide and for each of the utilities.
Iowa uses the five classic benefit-cost tests identified in the California Standard Practice Manual. These are the Utility/Programs Administrator (UCT), Participant (PCT), Social Cost (SCT), Total Resource Cost (TRC) and Ratepayer Impact Measure (RIM). The rules for benefit-cost tests are stated in Iowa Code §476.6(13) and IAC 199—35.8(2). Iowa specifies the SCT to be its primary cost-effectiveness test. These benefit-cost tests are required for overall portfolio, total program, customer project, and individual measure level screening, with exceptions for low-income programs, pilots, and new technologies. Iowa’s SCT test accounts for avoided environmental compliance costs.
The current energy efficiency plans (EEP-2018-0002 - MidAmerican, EEP-2018-0003 - IPL, EEP-2018-0004 - Black Hills, and EEP-2018-0005 - Liberty) contains the EM&V plans for the 2019-2023 plan cycle.
According to the Database of State Efficiency Screening Practices (DSESP), Iowa relies on the Societal Cost Test (SCT) and considers it to be its primary cost-effectiveness test. However, Iowa rate-regulated utility customers may opt out of the five-year energy efficiency plan if a program does not pass the RIM test. Iowa’s SCT accounts for non-energy benefits such as asset value, natural gas savings, and appliance water savings. Iowa also accounts for avoided environmental costs. Low-income programs do not need to pass a cost-effectiveness test.
Further information on cost-effectiveness screening practices for Iowa is available in the Database of State Efficiency Screening Practices (DSESP), a resource of the National Efficiency Screening Project (NESP). Further information on health and environmental benefits is available in ACEEE’s Overview of State Approaches to Account for Health and Environmental Benefits of Energy Efficiency.

Guidelines for Low-Income Energy Efficiency Programs List All
Requirements for State and Utility Support of Low-Income Energy Efficiency Programs
Iowa Code 476.6 (13 and 476.6 (15) require that the investor-owned utilities' energy efficiency plans include programs for low-income customers but does not require a specific level of spending.
Cost-Effectiveness Rules for Low-Income Energy Efficiency Programs
According to IAC 199 – 35.5(4)(c)(3), "...Energy Efficiency programs for qualified low-income persons and for tree planting programs, educational programs, and assessments of consumers' needs for information to make effective choices regarding energy use and energy efficiency need not be cost-effective and shall not be considered in determining cost-effectiveness of plans as a whole."
Coordination of Ratepayer-Funded Low-Income Programs with WAP Services
IPL, Black Hills Energy, and MidAmerican Energy jointly implement the Weatherization Assistance Program (WAP) through the Iowa Utility Association (IUA). The utilities contribute program funding through the Iowa Department of Human Rights (DHR). These funds reimburse Community Action Program (CAP) agencies for the costs of performing energy assessments and purchasing and installing qualifying energy efficiency measures in residences occupied by low-income families. WAP is available to homeowners and renters whose income level is at or below 200% of the Federal Poverty Level (FPL). Homes occupied by the elderly, individuals with disabilities, and families with children under the age of six are prioritized for weatherization assistance, as are households with high usage. CAP agencies market and deliver the program to low-income customers, and the DHR's Division of Community Action Agencies (DCAA) administers the program.
The Iowa Division of Community Action Agencies (DCAA), in coordination with investor-owned utilities, conducts and publishes an annual evaluation of the Iowa Weatherization Program. The performance assessment is used to determine technical assistance and training needs.
