Cyber and physical securityAs cyber and physical threats grow, Alliant Energy remains focused on the security, reliability and resiliency of the energy grid and our data systems. Our programs are routinely reviewed and updated to improve performance with results reported to the Operations Committee of the Board of Directors.

Our cyber security team regularly assesses our processes and procedures against industry standards such as the National Institute of Standard and Technology (NIST) Cybersecurity Framework. This effort includes annually reviewing technology investments to improve our cybersecurity posture as well as ensuring the appropriate level of educated cybersecurity staff.

Alliant Energy continues to evolve our programs and response strategies to improve our situational awareness, proactively reduce risks and ensure that we are ready to respond to events beyond our control. An integral part to our programs includes having protocols in place to address cyber and physical breaches and threats. These protocols are drilled routinely and are handled according to our Incident Response Plans. We are also participating in an elective tabletop exercise conducted by EPRI, which will aid in understanding the interactions between operating and information technologies during incident response.

Alliant Energy works with numerous local, regional and national stakeholders as part of its security program and adheres to all applicable compliance requirements, protocols and reporting. These include:

North American Electric Reliability Corporation Critical Infrastructure Protection Standards

Federal Energy Regulatory Commission Licensing Standards

Electric system reliability Alliant Energy is continually working to improve our electric system reliability; however, some power outages still occur. The majority are the result of weather-related events, trees and wildlife. As preventive measures, we conduct tree trimming near our distribution lines and install animal guards on pole-top transformers. Other events such as digging, construction or auto accidents can damage lines, poles or other equipment and cause service interruptions. An electrical overload may also cause the equipment to fail. Regardless of the reason for an outage, Alliant Energy works to restore power as quickly, efficiently and safely as possible.

Alliant Energy is focused on providing our customers with reliable electricity and restoring power quickly* .

52% of our customers experienced zero power outages in 2018

76% of outage events in 2018 restored power within two hours or less

The average U.S. electricity customer has at least one power outage lasting about two hours based on the latest comparable data from the U.S. Energy Information Administration.*Data provided excludes planned and major weather-related events.

Natural gas system performanceAlliant Energy natural gas transmission pipelines deliver gas directly to some large industrial customers and to Alliant Energy gate stations, where pressure is lowered for final distribution to utility customers. The distribution systems consist of mains, which are usually located along or under city streets, and smaller service lines that branch off the mains and distribute natural gas service to homes and businesses. None of these pipeline systems are constructed of potentially high-risk materials, such as cast and wrought iron or non-protected bare steel.

Alliant Energy is dedicated to keeping its employees, customers, and communities safe through training, education, and awareness. All Alliant Energy journeymen crews and service responders are trained on emergency response and are available 24 hours a day, seven days a week. In addition, our company’s Transmission and Distribution Integrity Management Programs provide a process for inspecting and assessing the condition of Alliant Energy-owned natural gas pipelines and establishing a maintenance program based on regulatory requirements and best industry practices.

Workforce Care for others is a Core Value at Alliant Energy: Together we create a workplace where people feel like they belong and can use their unique backgrounds, talents and perspectives to their fullest potential. Diversity includes a rich mixture of attributes that make each of us unique. Our company treats all employees with respect and supports a diverse and inclusive workplace. This environment contributes to our ability to provide safe, reliable power and excellent customer service.

Diversity is more than just the visible: races, ethnicities and genders. It includes education, cultural experiences, religion, sexual orientation, gender identity and many other invisible differences that make each of us unique. Our goal is to promote inclusion so that each employee feels free to contribute to their fullest potential.

We provide resources to our employees that foster inclusion and a better understanding about diversity. Our Employee Resource Groups give all employees an opportunity to grow professionally, network, build community relationships and socialize with other employees.

Collective Bargaining . Maintaining strong labor relations is integral to our company’s success. As of the end of 2018, 55% of Alliant Energy employees were covered under collective bargaining agreements. And, we partner with our unions as they serve an important role in developing our talent pipeline and training our employees. Alliant Energy respects the right of our employees to join, form or not to join a labor union without fear of reprisal, intimidation or harassment. Alliant Energy is committed to constructive dialogue and good faith negotiations with legally recognized unions.


Supplier programsAlliant Energy approaches relationships with suppliers the way we approach everything else we do: focused on delivering energy and exceptional service that our customers and communities can count on – safely, efficiently and responsibly.

Conduct and ethics: All suppliers are expected to adhere to the Alliant Energy Code of Conduct. In particular, that our suppliers will participate in bid processes and procurement practices in accordance with best practices. Best practices include communicating only with the named Alliant Energy representatives during contract negotiations or bid evaluation, refraining from “back door selling,” and attempts to influence Alliant Energy employees or senior management in order to obtain work.

Anti-bribery and anti-corruption: Alliant Energy will not tolerate any kind of corrupt activity. We comply with all anti-corruption laws. That means we do not pay bribes – providing anything of value to illegally influence business decisions, obtain illegal advantages over other parties, or reward another party for past illegal actions. We do not pay kickbacks – illegal compensation for favorable treatment in business relationships or improper services. And we do not make facilitation payments – illegal payments to “grease the skids” to expedite services of governments or government officials.

Supplier and contractor safety requirements: Since 2013, our company has partnered with ISNetworld to improve safety performance of contractors performing physical work, such as repairing equipment and building new facilities. The program enables our company to objectively manage contractor safety prequalification requirements.

Supplier sustainability qualifications: Alliant Energy is a member of the Electric Utility Industry Sustainable Supply Chain Alliance. Through participation in this organization, our company conducts supplier surveys designed to benchmark sustainability performance and educate on best practices. We also track progress through a supply chain sustainability maturity assessment to support future improvements.

Supplier diversity: Alliant Energy provides equal access for all qualified businesses, including those owned by women, minorities, LGBT, service-disabled veterans and small-business designations. Tracking includes both direct Tier 1 diverse suppliers and also Tier 2 suppliers that report on diverse spend. To promote the use of diverse suppliers, all bids over $100,000 are required to consider a diverse supplier. Beginning 2015, we increased our company target for total annual spend from diverse suppliers from 10% to 15%. Our 2018 results were 8.6%. This amount was influenced by our large capital spend on wind turbines, that was procured from large, publicly-traded corporations and diluted our diverse supplier spending.

In Wisconsin

Since 2001, the energy savings for Wisconsin residential and some business programs have been part of the consolidated Focus on Energy (FoE) program. This program is managed by the state of Wisconsin. WPL contributes 1.2% of its annual retail utility revenues to help fund FoE. Program goals and initiatives for FoE are established on a statewide basis working with all participating utilities and updates are reported publicly at https://focusonenergy.com/about/participating-utilities/utility-resources.

In 2018, WPL introduced the Energy Edge program to provide an online platform that empowers our Wisconsin commercial and industrial customers to benchmark their energy usage and set sustainability goals to improve performance. This digital tool provides deeper analytics including cost comparisons over time, weather impacts, and usage breakdowns. Wisconsin residential customers can also sign-up for our Energy Advisor program to get free, personalized advice on how to save energy and money. This online program engages customers by regularly delivering customized actions that appeal to their personal motivations for saving energy.

In Iowa

IPL’s Energy Efficiency Plan (EEP) is reviewed and approved by the Iowa Utilities Board. Results for IPL’s 2014-2018 EEP included achieving savings of 889.4 Gigawatt-hours (over 100% of goal) and 11.4 million therms (96% of goal). Spending was approximately $391.2 million (94% of allowable). In March 2019, IPL received regulatory approval of its 2019-2023 EEP. The new EEP includes savings targets of 610.8 Gigawatt-hours and 2.5 million therms. The spending target of $232.9 million reflects recently passed state laws that cap spending. Annual EEP reports are filed under docket EEP-2018-0003 at https://efs.iowa.gov/.

In 2018, IPL launched a Strategic Energy Management (SEM) Program to assist Iowa commercial and industrial customers develop energy action plans. SEM promotes behavior-based energy savings and investment in energy-efficient capital improvements. IPL provides customers with education, technical support, a baseline energy management assessment, benchmarking tools and energy usage data. The platform allows our customers to incorporate energy reduction strategies, sustainability goals and energy management into daily operations.

Cumulative 10-year energy savings results:

Electricity – 2,859 million kilowatt-hours Gas – 63 million therms

*Data provided based on first year annual incremental savings. This includes estimated savings in Wisconsin through the Focus on Energy (FoE) program and actual savings from the program in Iowa.

Renewable energy credits (RECs) represent proof that 1 MWh of electricity was generated from an eligible renewable energy resource. Alliant Energy’s RECs are tracked in the Midwest Renewable Energy Tracking System (M-RETS). RECs can be sold and traded, giving the purchaser of the RECs claim to the renewable energy and environmental attributes. The RECs generated by Alliant Energy may be sold or exchanged on the renewable energy market, including to buyers not located in the states served with energy from IPL or WPL.

Source: Alliant Energy records and Federal Energy Regulatory Commission (FERC) Form 1. In 2015, IPL closed the sale of its electric distribution assets in Minnesota and no longer provides retail sales to customers in this service territory. Compliance data shown includes REC retirements for IPL’s retail sales in Minnesota to meet the existing RPS requirements through the closing date in 2015. The number of RECs retired in a given RPS compliance year does not necessarily mean those RECs were all generated that year due to the allowed use of banked RECs in Minnesota and Wisconsin.

Environmental managementAlliant Energy’s Environmental Commitment Statement provides the guiding principles for employees to demonstrate our core value to Act for Tomorrow. Furthermore, our company monitors environmental incidents, provides an Environmental Management Program and conducts formal assessments.

Our company has supported efforts to protect the endangered Karner Blue butterfly since 1999 .


Environmental Incident Monitoring Process

Our company goal is to meet all of our environmental requirements – all the time. We maintain an Environmental Information Management System (EIMS) to manage and track approximately 4,000 environmental tasks to ensure compliance.

Occasionally, environmental incidents occur for a variety of reasons, including, but not limited to, mechanical failures, human performance, wildlife, and extreme weather. We define environmental incidents as a non-routine occurrence that has the potential to directly or indirectly result in an impact to the environment and involves an actual consequence or potential risk to our company, including risk to company reputation. Environmental incidents have the potential to result in an official notice of non-compliance (NOC) from a regulatory agency and are treated very seriously.

When environmental incidents do occur, we strive to learn from them and prevent them from occurring again. The Environmental Services and Corporate Sustainability department tracks incidents on a monthly basis and shares relevant information with others throughout the company. We also conduct a root cause analysis within 20 working days of the incident. The outcome is an action plan that is approved by management. In addition, results are used to proactively develop targeted processes and programs to prevent reoccurrence.

Environmental Management Program

In 2017, Alliant Energy also created a new Environmental Management Program (EMP) that focuses on our electric generation facilities, because these operations are subject to the most environmental compliance requirements. The program partners environmental subject matter experts with plant operational personnel to improve our environmental performance.

The main components of the EMP are to: identify gaps in existing processes that may impede the successful completion of environmental obligations for our operations; develop or refine processes in order to ensure continued compliance with all environmental requirements, regulations and responsibilities; and achieve zero environmental incidents. Annually, the EMP reviews historical trends in environmental incidents and provides a framework for prioritizing the development of processes and tools to proactively address them.

Environmental Assessment Program

The purpose of Alliant Energy’s Environmental Assessment program is to identify and assess any reasonably foreseeable risks associated with environmental conditions attributable to our company’s operations and eliminate or mitigate such risk. In addition to verifying compliance with applicable requirements, our company’s program promotes educational awareness and acknowledges areas of exemplary performance.

Our leadership team endorses these compliance reviews, approves the assessment plans, and monitors the assessment outcomes and resolutions through a monthly Environmental Assessment Aging Scorecard. The results of each assessment are discussed with facility managers and site personnel. The resolution of each

issue that is identified is tracked to completion in our EIMS. The overall assessment outcomes are used to plan and implement training programs, as well as, improve practices and procedures used to ensure compliance.

During 2018, Alliant Energy conducted environmental assessments on approximately 30% of eligible facilities, all of which includes those with operations that are subject to environmental regulatory requirements.

2018 Environmental Compliance Results

Alliant Energy operates in compliance with environmental requirements. However, there are occasions when the company does receive a NOC from a regulatory agency, which can result in fines or penalties. In 2018, Alliant Energy was issued one NOC related to wastewater monitoring procedures for an exceeded Total Suspended Solids permit limit. There was no fine or penalty imposed for this incident.

Greenhouse gasesScope 1 greenhouse gas (GHG) emissions are direct emissions from owned or controlled sources. The primary GHG source from Alliant Energy and its utility subsidiaries (IPL and WPL) are the direct emissions of carbon dioxide (CO2) from fossil-fueled generation. In addition, combustion emissions occur from operation of our company’s vehicle fleet and there are also fugitive emissions that occur from natural gas distribution operations. These GHG emissions comprise the company’s Scope 1 footprint which totaled 17.5 million metric tons of CO2-equivalent (CO2e) for 2018 based on equity-share.

The CO2e is a measure used to compare the emissions from various greenhouse gases based on their Global Warming Potential (GWP). The CO2e for a gas is derived by multiplying the mass of the gas by the associated GWP and is determined as follows:

Total CO2e = Carbon dioxide (CO2) x 1 + methane (CH4) x 25 + nitrous oxide (N2O) x 298

The CO2 emissions from fossil-fueled electric generation represented the majority of our total annual CO2e at over 97%.

The EPA Mandatory Greenhouse Gas Reporting Rule protocols apply to the monitoring and reporting of our CO2e emissions. More specifically, this includes fossil-fueled generation facilities (Subpart D) and auxiliary combustion equipment (Subpart C). In addition, indirect GHG emissions from the combustion of the natural gas supplied to customers (Subpart NN) and fugitive losses from natural gas distribution operations (Subpart W).

Source: Data collected for EPA Annual Mandatory GHG Reports based on protocols issued at 40 CFR Part 98 for Subparts C, D and W. Direct CO2e emissions are adjusted for equity share of joint-owned electric generating units. Emissions include all fossil-fueled generation and auxiliary combustion sources including those facilities below the EPA reporting thresholds. Fleet vehicle emissions based on fuel usage or mileage and EPA published GHG emission factors.

Scope 2 emissions are indirect GHG emissions from the generation of purchased energy. At some facilities, IPL and WPL need to purchase power for business operations outside of the Alliant Energy service area. The Scope 2 GHG emissions estimated for this purchased energy in 2018 was approximately 5,200 metric tons of CO2e.

The system CO2e emission rate represents the CO2e emission rate attributable to the retail portion of electric energy sales for retail customers (not including Second Nature), as reported in Alliant Energy Corporation’s annual Form 10-K to the U.S. Securities and Exchange Commission (SEC). Fossil fuel combustion CO2e emissions are calculated in accordance with the U.S. Environmental Protection Agency (EPA) mandatory Greenhouse Gas Reporting Program (GHGRP) regulations under 40 CFR Part 98. The CO2e system emission rate has been adjusted to reflect Alliant Energy’s annual share of emissions and generation from jointly owned electric generation units. In addition, the CO2e system emission rate has been adjusted for null power and includes emissions and generation attributable to Alliant Energy’s market energy purchases. Null power includes sales of renewable energy credits (RECs), RECs retired for Alliant Energy’s Green Pricing Program – Second Nature, and renewable energy agreements with outside parties.

Null power and market energy purchase CO2 emissions have been calculated using the Green-e® residual emission rate factor for the North American Electric Reliability Corporation (NERC) Midwest Reliability Organization (MRO) Region. The residual emission rate factor is available at: www.green-e.org. The EPA’s Emissions and Generation Resource Integrated Database (eGRID) emission factors have been used for null power and market energy purchase methane (CH4) and nitrous oxide (N2O) emissions. The eGRID emission factors are available at: www.epa.gov/energy/egrid. Total CO2e was calculated with global warming potentials (GWP) as follows: CO2 = 1, CH4 = 25, N2O = 298.

Alliant Energy Corporation makes no assurances regarding use of this information by external parties in relation to any marketing or other sustainability claims, or the validity of this information as pertains to the U.S. Federal Trade Commission (FTC) Green Guides under 16 CFR Part 260.

Alliant Energy Corporation reserves the right to use all or some of the renewable energy attributes associated with generation from renewable energy sources in future years to comply with renewable energy standards or other regulatory requirements or to sell the renewable energy attributes to third parties in the form of RECs or other environmental commodities.

Notes:

* Generating facilities listed above include the coal-fired and natural gas combined cycle plants that are the primary users of water for our company’s electricity production.

** Non-contact cooling water is returned to the river or lake that is the primary source of water, except as noted below.

Columbia Energy Center uses surface water from the Wisconsin River and discharges to an on-site cooling pond in accordance with their Wisconsin Pollutant Discharge Elimination System (WPDES) permit.

Riverside Energy Center uses groundwater as the main supply and discharges to the Rock River.

Emery Generating Station uses groundwater and treated sanitary water, also called “gray water,” that is returned to the local Publicly Owned Treatment Works (POTW).

Marshalltown Generating Station went into service in April 2017 and uses city water supply that is discharged to the city sewer.

The company’s generating facilities may supplement water use with well water and city water.

For electricity production, we predominantly use water to make steam and cool equipment. Most of this is “non-contact” cooling water that is pumped through the generating facility in piping systems where water cools process equipment indirectly. Therefore, our actual water consumption is very low, with 97% returned overall for subsequent reuse. All water discharges meet federal and state regulations for freshwater quality.

In addition, our company has general water use at our office buildings and other facilities that provide operational support, such as garages, warehouses, and equipment maintenance. This water use includes potable drinking water, sanitary, and various ancillary uses. The source of this water is largely from municipal water systems and in some cases groundwater from on-site wells. This general water use represents less than 1% of our total water consumption when combined with electrical production.

Being located in the Midwest, Alliant Energy historically has not been directly impacted by droughts or water scarcity issues that have caused operational slow-downs or temporary shortages as has been experienced by utilities located in water-stressed regions of the United States. However, our company proactively considers both water availability and quality in our planning and ongoing operations. Our new natural gas-fired power plants are designed with cooling tower technology that minimizes water use. Negligible water will be necessary for our new wind farms and solar facilities.

Alliant Energy’s water withdrawals have decreased significantly due to retirement of fossil-fueled generating facilities. In addition, our company is continuing to implement initiatives to reduce water use at our remaining fossil-fueled generating facilities such as use of variable speed pumps to increase efficiency and best

management practices to conserve plant operational water use. We expect to modify our remaining coal-fired facilities to eliminate wet ash handling processes and install dry ash handling equipment.

Our fossil-fueled generating facilities monitor parameters to ensure proper water quality for plant use, as well as adherence to discharge permitting requirements, which protect receiving water bodies. Alliant Energy is also a participant in an ongoing EPRI technical workgroup that is specifically focused on improving the quality and quantity of water available in the Great Lakes region. In February 2019, our company received an EPRI Technology Transfer Award for a demonstration project that used aerial drones to measure water temperatures of cooling water thermal plumes in support of regulatory permit renewals. The tests from this project resulted in a proof-of-concept in using drones to replace boat surveys in gathering data.

We also proactively take steps to protect our facilities in the event of increased precipitation by developing Flood Plans. The plans take into account that the key to successful flood preparations is advanced planning, careful monitoring of predicted water levels, early preparation and training.

The Board of Directors has delegated to the Operations Committee oversight of water management related matters including policy, compliance, business plans, and capital investments for large strategic projects . The Operations Committee reviews and advises the Board of Directors which has final approval authority .

Primary watersheds for Alliant Energy’s regulated utilities, IPL and WPL, operations include the Great Lakes and Upper Mississippi River drainage basins of the United States. Cooling water technologies used at our fossil-fueled facilities include once-through and recirculating with cooling towers.

Waste managementAlliant Energy continues to focus on improving how we manage waste in our daily operations as well as when our company retrofits, expands and decommissions our facilities. Our large construction contracts require contractors to reduce landfill waste by 75%. In 2018, for all large projects, we achieved 82% by diverting over 14,000 tons of metal, wood, concrete asphalt and other waste materials from landfills.

Collaborating to support a sustainable waste vendor audit process

In 2019, Alliant Energy joined CHWMEG, Inc., which is a non-profit organization comprised of companies interested in collaborating to efficiently conduct waste vendor audits. Routine audits assess a waste disposal company against industry standards and applicable regulatory compliance requirements. This helps to ensure our contracted waste vendors are performing work in a safe and environmentally responsible manner. Our company’s participation provides comprehensive, independent audits of commercial waste companies that we may hire to treat, store, dispose, recycle/regenerate, or transport waste and spent materials. Our membership offers Alliant Energy an opportunity to complement our current waste management program.

Dumpster dive helps improve our recycling practices

In April 2019, our Iowa Sustainability Squad members and Facilities Department worked in collaboration with the Iowa Waste Exchange to conduct a thorough waste audit at the Cedar Rapids General Office. The Iowa Waste Exchange is a program housed within the Iowa Department of Natural Resources that provides assistance to assess waste streams in order to help identify reuse and recycling opportunities.

Volunteers sorted a day’s worth of garbage (recycling, compost, trash, etc.), which were individually weighed. The data was used by Iowa Waste Exchange to issue a report that provides confirmation of good practices and recommendations for future waste management improvements. Outcomes from this report will be used to enhance existing practices at all of our facilities.

Coal combustion residualsCoal combustion residuals (CCR) are what remain after the direct combustion of coal at generating stations and include residuals from air quality control systems. Alliant Energy’s goal is to manage CCR safely and responsibly to protect both the environment and the public while assuring compliance with state and federal regulations.

We are complying with the EPA’s regulations for CCR management and disposal, including elimination of wet ash handling processes and closure of our coal ash ponds. Our CCR website shares required compliance information and monitoring data. It can be directly accessed at ccr.alliantenergy.com.

Alliant Energy works with state regulatory agencies to identify approved beneficial uses for CCR. Material that cannot be beneficially reused is placed in landfills that are permitted and include engineering design and controls that meet or exceed applicable federal, state and local requirements.

There are different types of CCR:

Fly ash is a very fine powder-like particle that is collected by emission controls.

Bottom ash is a coarse, granular sand-like material collected from the bottom of the boilers.

Scrubber solids consist of lime that is reacted in air quality control systems to reduce SO2 emissions. These solids are light in color, contain small amounts of fly ash and are typically collected in a baghouse.

In 2018, we were able to beneficially use 57% of the CCR generated.

2018 beneficial use program highlights:

Our goal is to beneficially use our CCR reserves in existing and new markets, in lieu of landfilling. To meet this goal, Alliant Energy works closely with universities and EPRI on research to develop new, responsible beneficial uses that reduce disposal while protecting public health and the environment.

Sold 100% of the Class C fly ash to the cement industry. Class C fly ash has cement properties preferered to enhance concrete strength. Also sold bottom ash into cement markets.

Continued to utilize scrubber solids to improve agricultural soil conditions, resulting in reduced landfilling and lower customer costs.

* Encapsulated uses: Cement Readymix, cement raw feed, subbase under hard surfaces, asphalt uses.

**Unencapsulated uses: Cattle feed lots, storage pads, agricultural use, grit blasting.

Ecosystem and habitat supportAlliant Energy’s environmental stewardship includes a longstanding tradition of ecosystem and habitat support. We work diligently to minimize impacts, protect and enhance natural areas to support various species, including those that are or may become threatened or endangered.

Our company has been a full partner in the Karner Blue Butterfly Habitat Conservation Plan since 1999 in Wisconsin.

We have collaborated with the Wisconsin Department of Natural Resources (WDNR) to increase lake sturgeon populations in the Wisconsin River since 1997.

Our company supports research and other efforts for preservation of the Monarch butterfly, including the Iowa Monarch Conservation Consortium, Wisconsin Monarch Collaborative and the Energy Resources Center’s Right-of-Way as Habitat Working Group.

We are a founding member of the Power-in-Pollinators Initiative, which is a collaborative conservation effort through EPRI.

For our growing wind turbine fleet, we have also supported EPRI-sponsored research aimed at protecting bat species and employing voluntary seasonal best practices for wind generation operations.

Ecosystem and habitat support

Native prairie and pollinator habitat 2,516 acres

Karner Blue Butterfly 275,635 acres

Our voluntary Avian Protection Plan (APP) formalizes and enhances our past practices of avian protection and incorporates industry best management practices for new construction or rebuilds of our distribution and wind generation facilities. There are two main categories for the best practices included in the APP – reporting and design.

Reporting best practices include procedures on recording incidents and what actions were taken to minimize the risk in those locations.

Design-based best practices include various retrofits such as increased spacing between energized and grounding equipment, bird diverters on electrical lines and covering certain electrical parts.

As our company’s owned wind production increases, the APP also covers best management practices to reduce impacts to birds as well as bats. At night in the fall during the primary bat migration season, turbines are “feathered” so that the blades are pitched parallel to the wind and reduce their revolution speed.

Alliant Energy uses Horizontal Directional Drilling (HDD) for various infrastructure construction projects to decrease impacts to the environment. Directional drilling is used to minimize impact on a wetland, waterway, endangered habitat and/or well established native landscape that conventional trenching would cause. This construction method is recognized by the WDNR and the U.S. Fish and Wildlife Service as a way to reduce the impact to the Karner Blue Butterfly, wetlands and many other environmentally sensitive areas.

Nesting platforms provide a safe refuge for ospreyOspreys are large birds that can have a wingspan of up to six feet. Their diet is primarily fish, and they prefer to build their nests up high so they can get a good view of the landscape around them. Unfortunately, this makes our utility poles an inviting place for ospreys to nest. Nesting spots on top of our poles can be a safety issue for osprey, as well as for our employees when they need to access the equipment a nest is sitting on.

Our company works with the Iowa and Wisconsin Departments of Natural Resources and area raptor projects to install nesting platforms for the ospreys. This gives the birds a place to nest that is both elevated and safe. Nesting platforms installed by our company and other organizations across the country are partly why the osprey population has grown significantly over the last several years.


Envision recognitionThe EnvisionTM system rates the sustainability of infrastructure projects across the full range of environmental, social and economic impacts. The process measures sustainable efforts using a scorecard that applies credits/points that are subject to verification by an independent third party providing a final overall project score and achievement level.

Envision Version 2 focuses on five key categories of sustainability for its framework including: Quality of Life, Leadership, Resource Allocation, Natural World, and Climate and Risk. These five categories encompass 60 credits, resulting in four levels of achievement: Bronze (20%), Silver (30%), Gold (40%), and Platinum (50%).

Why does Alliant Energy use Envision?

Envision provides an opportunity to enhance our sustainability by providing a formal process with external benchmarks and best practices to implement into our company’s infrastructure projects. The Envision Review Board provides independent verification to show that we’re doing what’s right for our stakeholders and the community. Envision projects use the framework to plan, design, and construct with a long-term vision for the future.
