Five panelists are coming to the University of Iowa on Wednesday to discuss the need for expanded solar energy at an event titled “Decarb 2040.”
The panel is comprised of academic, community, and industry experts who plan to present research on how decisions regarding the adoption of solar power in different locations are made. The presentation will take place on Oct. 27 from noon until 1:30 pm.
Following the presentation, a Q&A will focus on future research and funding opportunities. The panel consists of the following guests:
Chris Hoffman, Vice President of Solar PV Sales, Moxie Solar
Ion “Bodi” Vasi, Associate Professor of Sociology and Management and Organizations
Charlie Nichols, Linn County Planning and Development
Travis Kraus, Iowa Initiative for Sustainable Communities
Rachel Kilberg, City of Iowa City Assistant City Manager
The event is held via Zoom. Undergraduates, graduate students, postdocs, staff, and faculty are welcome to attend. Individuals can register here.
The University of Iowa’s Office of the Vice President of Research is hosting the event which aims to focus on Iowa as an energy exporter in the coming era of decarbonization. Iowa has abundant resources in solar and wind energy as well as bioenergy. The recent research focuses on how the state could use these resources to become a net exporter of energy by 2040 based on current plans to focus on energy sources that use less carbon.
Two solar energy projects have been proposed this month in Iowa. One project will take place in Linn County, the other in Dubuque County.
Coggon Solar LLC filed an application last week for permission to build a 640-acre facility in Linn County. The planned acreage would meet the electricity needs of more than 16,000 households. The land is currently utilized for farming. The LLC is a partnership between the Clenera and Central Iowa Power Cooperative. If the application is approved, the county would receive nearly $4.8 million in property taxes. The Cedar Rapids Gazette reported that long-term leases have already been signed by Coggon Solar and property owners on the land where the project plans to be.
Linn County isn’t the only area in Iowa preparing for a new solar energy project. Dubuque’s city council approved funding for a pilot program to help install solar panels on a few residents’ homes. The program will select 10 residents to participate this year, and each will receive $3,285. The program aims to decrease the burden of energy costs on low- to moderate-income households in the city.
Both programs come months after solar tax credits were not renewed by the Iowa Legislature. Hundreds of Iowans lost an average of $3,200 after the credits failed to pass, according to Iowa Capital Dispatch.
A new report showed that Iowa taxpayers could save $375 million if every county seat, county government and school district installed an average-sized solar energy system.
Auditor Rob Sand reached out to local governments, school districts and the Iowa Solar Energy Trade Association for information on solar installations in the state. Of the 27 projects he randomly chose to analyze, 13 responded to questions. The report revealed that solar panels save local governments and school districts an average of $26,475 each year, and each installation could save $716,437 over its lifetime, according to an Iowa Capital Dispatch article.
Sand came up with the idea for the study while discussing energy savings with family members who own solar panels. He hoped to add solar energy to his Public Innovations and Efficiencies (PIE) program, a project that aims to save taxpayers money through energy conservation. Once the study was complete, Sand noted that school districts could use sales tax receipts for installation and maintenance, reducing pressure on general funds supported by property taxes.
Some local governments and school districts have avoided paying upfront costs for their installations altogether. The city of Letts and Sigourney schools both build solar systems with no upfront payments, and others could do the same by leasing equipment or buying power from other solar energy system owners. The price of solar installations dropped 90% over the past 10 years, and most systems can pay for themselves in five to 15 years, depending on individual circumstances.
Webster County recently approved plans to build a 957-acre solar field. The energy produced by the panels would be able to power 30,000 homes.
Holliday Creek Solar LLC, based in Minneapolis, Minnesota will build the field and eventually transfer the site’s certificate to MidAmerican Energy. Construction is set to begin in the spring and conclude by next winter, according to Webster County planning and zoning administrator Jeff Johnson. The energy will be directed to a nearby substation, then exported to a transmission grid providing energy to other counties.
“We are moving in the right direction,” Johnson said many participating landlords and homeowners in the county are interested in this project.
While Iowa solar panels net capacity has grown from 2-megawatts (MW) in 2012 to as much as 160 MW in 2020, many counties have yet to adopt solar and wind ordinances which provide construction guidelines for these projects.
The Webster County Board of Adjustment approved the project on Jan. 18, followed by the Iowa Utilities Board on Feb. 3.
MidAmerican Energy has proposed its first-ever solar energy project: a public-private partnership with the City of Iowa City.
The city would lease nearly 19 unused acres at Waterworks Prairie Park to MidAmerican for 30 years, installing 10,000 solar panels, according to The Gazette.The energy generated would be able to power 580 average Iowa homes, a MidAmerican representative said in the article.
The Iowa City City Council will hold a hearing on the proposal later this month. If the city approves the plan, it will receive annual payment for the land.
The project would not impact the park’s walking trail. The Gazette reported that the land in question is currently planted with prairie, which would be replaced with “low-growth pollinators and perennials.”
The so-called “sunshine tax” might have a bright and cheery name, but the proposed fee could put a real damper on private solar power in Iowa.
Described in House Study Bill 185 and Senate Study Bill 1201, the “Solar Options Lead to Affordable Renewables (SOLAR) Act” would impose an over $300 annual fee on solar customers — property owners with small-scale solar panel setups who sell excess power back to the grid. The fee would cover the cost of using the electric grid and support Iowa’s energy infrastructure.
Currently, such customers can expect to pay off the high initial cost of solar panel installation in less than 10 years through savings on energy bills and sales of excess power. Cedar Rapids City Councilman Tyler Olson told the designated House subcommittee the fee would extend that period to as much as 20 years, as reported in the Gazette. This would greatly discourage private individuals from investing in home setups, which typically last about 25 years.
Supporters of the fee, including major Iowa utilities like MidAmerican and Alliant Energy, say it is unfair that customers who do not generate their own power absorb the cost of maintaining power infrastructure that is used by solar generators.
“Growth is possible when policies allow all customers to benefit from renewable energy,” MidAmerican Energy’s president and CEO said in a press release. “Common sense legislation focused on keeping costs low and affordable for everyone provides the best opportunity to grow solar in Iowa.”
Opponents say the fee would only allow solar to grow for large corporations, however, and that it would kill the future of Iowa’s growing solar industry, which largely develops and installs systems for private homes, businesses and farms.
On Tuesday, the Gazette reported that the the bill would soon move forward in the Iowa House, to the full House Commerce Committee. Yesterday, the Iowa Senate held a hearing on their version of the bill, and did the same.There is a push among some legislators to delay the conversation until the Iowa Utilities Board finishes an assessment of compensation for solar energy producers next year.
Homeowners in Linn County were encouraged to combine their buying power to significantly reduce the cost of installing solar panels this summer through the Solarize Cedar Rapids and Linn County initiative.
Organized by the City of Cedar Rapids, Linn County, The Nature Conservancy, Indian Creek Nature Center, Iowa 350 and the Midwest Renewable Energy Association (MREA), participants were offered a significant per Watt discount each time the volume of buyers surpassed program tiers. The base price for participants was $2.45/W. All participants received a $0.05/W discount each time the group buy reached one of four milestones: 50 kilowatts (kW), 150 kW, 250 kW, and 350 kW.
The program offered a total of 23 educational sessions, or Solar Power Hours, for interested parties to learn more about the evolving solar industry and this initiative.
Amy Drahos is a Senior Air Quality Scientist at Linn County Public Health. She said in a recent press release, “The community support for the Solarize program has been incredible. Nearly 500 people attended a Solar Power Hour or requested more information about the program, with 105 households deciding to install solar. This program was a success thanks to the enthusiastic response from Linn County citizens and the dedicated community partners who recognize the benefits of solar energy.”
In the end, 105 households signed up to install solar panel systems, and the initiative nearly double its highest goal of 350 kW, installing a total of 611 kW. The large group buy means that participants will receive a rebate of $200 per kilowatt installed, or an average of $1,164 per household.
Cedar Rapids Sustainability Coordinator, Eric Holthaus, commented on the city’s role in the program, “The City served as an educational partner in this program. Solar technology ten years ago is not the same as solar today. We enjoyed helping residents become informed on this energy option, and it looks like many were excited to take a step toward cleaner energy and lower utility bills.”
The Solarize Cedar Rapids and Linn County initiative also provides a substantial environmental payoff. It is estimated that program participants will generate a combined total of nearly 700,000 kWh of clean solar energy annually. MREA reports that 927,000 pounds of carbon dioxide and 14 million gallons of water will be offset by this initiative during the first year alone.
The MREA has implemented this program in several other parts of the Midwest including Milwaukee, Wisconsin and Urbana-Champaign and Bloomington-Normal, Illinois. However, “The Solarize Cedar Rapids and Linn County program contributed the highest kW contracted to date,” according to MREA Executive Director, Nick Hylla. He added, “There is obviously a tremendous amount of interest in solar energy in eastern Iowa.”
The program wrapped up on September 30th. All solar installations will be completed by December 31, 2017.
Tesla CEO Elon Musk is working to win over some U.S. homeowners who may be hesitant to install solar panels because of their bulky appearance. The company is introducing solar cell roof tiles to the market this summer that look just like conventional roofing options. The tiles are made of tempered glass, allowing the sun’s rays to reach solar cells tucked away within them. With four styles available: textured, smooth, tuscan and slate, the tiles are made to please the style-conscious homeowner.
The glass tiles come with a lifetime warranty and can allegedly handle hailstones traveling at 100 miles per hour with ease. Tesla compared this to conventional roof tiles, which shattered under the same conditions. Each tile’s solar cell is guaranteed to last 30 years.
The company started taking preorders in early May. It will begin installing roofs in California this June and complete installations throughout the country in the months that follow.
The increased popularity of energy efficient LED (light emitting diodes) lighting has moved to the farm and livestock farmers are saving on utility bills by embracing this trend.
Hog farmers in Iowa have been particularly quick to adopt the new technology. Washington, Iowa-based Sitler’s Supplies has sold more than 10,000 LED fixture and bulb sets in the past 18 months. This is to help accommodate the utility demands of livestock operations which can have up to 600 lights running for more than 16 hours per day.
Governmental and private entities have also embraced LED lighting in recent years although at $50-60 per fixture the technology is not yet affordable for some farmers. An LED bulb can have a lifespan of about 80,000 hours which is more than double than of a compact florescent.
Energy companies and lawmakers say a new tax credit will make the installation of solar energy systems on homes and businesses an affordable investment.
“A lot of people have been looking at solar energy systems and now, with the state tax credits, they’re starting to move forward,” Brad Duggan, energy efficiency project manager at Van Meter Inc. in Cedar Rapids said Tuesday. “It makes solar ripe for the residential use. I think it will push the market.”
The credit, which was signed into law by Gov. Terry Branstad last week, provides state tax credits for solar electric, solar hot water, and geothermal energy systems – allowing homeowners credits of up to $3,000 per project, and $15,000 for businesses.
