Heartland interns complete projects, create resources for customers’ benefit

Heartland’s two summer interns wrapped up their respective projects and presented their findings to the Heartland Board of Directors at their August meeting. Operations Engineering Intern Heather Ahlgrim and Customer Research Intern Coley Stoller each provided a detailed explanation of what they accomplished during their tenure at Heartland, their processes and how their projects will benefit our customers.

Heather Ahlgrim discussed how she created one-line diagrams at Heartland’s August board meeting.

Ahlgrim tackled multiple operations projects during her internship, but the bulk of her time was spent creating and updating one-line diagrams of Heartland’s customers’ delivery points, substations and metering equipment. This process involved visiting the communities and substations to gather information first-hand, visiting with local municipal officials as well as performing extensive research utilizing diagrams from Western Area Power Administration (WAPA) and Google Maps.

“I used a lot of resources for this project,” said Ahlgrim. “The electric utility employees at each town were the most helpful–without them, this project wouldn’t have been as successful.”

Prior to Ahlgrim’s project, Heartland had one-line diagrams for many of our customers on file, but most were outdated or contained minimal details. The new diagrams are much more elaborate and include more relevant information, such as Heartland’s and the city’s points of delivery, transmission owners and voltage, switch numbers and locations, alternate sources, city substation information, meter information, distribution owners and voltage, transformer ratings, and number of feeds going into a city.

“It’s important to have updated diagrams for a number of reasons,” noted Heartland Director of Power Supply Adam Graff.  “For instance, when customers are looking into a new project, their consultant may call Heartland for more information. Previously, we may not have been able to help due to our limited resources, but now we can. It’s important for the consultant and the city to know the limitations of the town’s system, and these diagrams will help determine if their current setup and equipment can handle more load. Heather did a great job putting them together.”

The other large project Ahlgrim completed involved organizing customer load data. She was asked to create a system that would allow Heartland staff to quickly find customer load data for a certain date and time as well as make comparisons between multiple data sets. She was given over 260,000 values depicting one year’s worth of hourly measurements from WAPA meters for every Heartland customer, which she organized into a custom look-up table.

“Heartland gave me a list of parameters and let me organize it how I thought best. I have never created anything of this magnitude or complexity, but it works beautifully,” she said.

Stoller’s internship involved a large amount of research as well as turning the data collected into usable, meaningful information. She was tasked with  pinpointing areas of economic opportunity in Heartland’s customer communities by providing a true overall cost of doing business and cost of living. The idea was to create meaningful comparisons between customers and other communities to determine each customer’s strengths and weaknesses when it comes to growth and expansion.

Coley Stoller presented her findings to the Heartland board of directors and staff at their August meeting.

Stoller spent the beginning of her internship making phone calls and performing internet searches to find rates for all of Heartland’s customers as well as approximately 50 other towns in the region. The next step was to organize the data in a manner that would be easy to manage and interpret. After collecting and compiling current electric, water and sewer rates from all the communities, she calculated the average rates and the average monthly payment for a residential customer. She also calculated average monthly payments for commercial customers based on different usage patterns.

From there, she categorized and identified strengths and weaknesses for each community using a simple ranking system. Categories ranked included rates, labor force data and tax data. Stoller also researched and documented other important information linked to community development, such as distances to major highways, local schools, and labor force and tax data.

“Based on the rankings, I was able to pick out patterns and trends in Heartland communities,” she said. “For instance, one observation I made was that towns located near or in the same county as a large university tend to have lower median ages and higher counts for people with Bachelor’s degrees. This likely means once students graduate, many of them are staying in the area. Those communities should look to capitalize on the flow of young people entering the workforce.”

The final step in Stoller’s project was developing individual profiles for each of Heartland’s customer communities, outlining her observations for each one as well as opportunities they can look to take advantage of in the future.

“Each of Heartland’s customers are unique and Coley’s research helped us identify each community’s specific attributes,” said Heartland Communications Manager Ann Hyland. “Economic development strategies are not one-size-fits-all and this information will help develop plans for growth that are specific to each city and their needs. We will be sharing this information with customers when we’re out visiting this fall.”

Heartland applied for and was awarded funding through the American Public Power Association’s DEED (Demonstration of Energy & Efficiency Developments) Program for Stoller’s internship. DEED awards scholarships to provide work experience to students at utilities and to support research projects that can be emulated by other utilities.

“Heartland was fortunate in hiring both Heather and Coley this summer,” added CEO Russell Olson. “Not only did they complete projects we’ve been wanting to accomplish for some time, they both had an amazing work ethic and were self-starters. We are proud to have given them some real-world experiences and wish them luck in all their future endeavors.”

At the completion of their internships, Ahlgrim returned to South Dakota State University in Brookings, SD to continue pursuing her degree in engineering and Stoller returned to Augustana University in Sioux Falls, SD to continue studying accounting.

Summer interns help with operations, economic development projects

Heartland is excited to welcome two interns to our office this summer. With a variety of projects to tackle, they look forward to a busy few months learning about the industry.

Heather Ahlgrim of Brookings, SD joined Heartland May 9 as Operations Engineering Intern. An electrical engineering major at South Dakota State University, Heather has experience as a student technician and teaching assistant for her school’s Electrical Engineering and Computer Science departments. During her internship, she will take on a number of operations projects, ranging from creating electric diagrams and visiting customers to analyzing market data.

Interns-Heather“Heather’s experience makes her a terrific candidate for the projects we have planned,” said Heartland Director of Power Supply Adam Graff. “In addition to the work she’ll complete, we hope she gains a better understanding of the power industry and will be encouraged to remain in the field after completing her studies.”

Heather’s first project is updating and creating one-line diagrams of Heartland’s customers’ delivery points, substations and metering equipment. This includes reading and analyzing all customer contracts to determine what information is missing or out-of-date as well as making visits to customer communities.

“This project benefits us as well as our customers,” said Graff. “We reference these diagrams when we work on contracts and wheeling agreements, so the information must be accurate and complete. However, these diagrams can also help those customers unfamiliar with electric systems better understand how their power is delivered.”

Heather has also found the experience beneficial and can relate some of it directly to her schooling.

“It’s really interesting reading the contracts and figuring out how the cities are connected,” she said. “At school, you learn how SDSU gets its power, for example, but now I can apply it to real life situations so it’s easier to understand.”

A portion of Heather’s work stems from Heartland’s recent integration into the Southwest Power Pool. Because the switch to SPP changed some billing procedures and other daily operations, she will build a database for customer transmission billing as well as analyze data and create summaries to increase Heartland’s market optimizations.

Heather chose to study electrical engineering because of her interest in math and science, and was influenced by her mom, who is an electrical engineering technician. Although she doesn’t have any careers in mind at this time, she enjoys the design aspect of electrical engineering and has experience building circuits and designing robots.

Heather will be a junior at SDSU in the fall and expects to graduate in May of 2018. She is a member of SDSU’s Society of Women Engineers, the Student Advisory Council, the Industry Advisory Board, Institute of Electrical and Electronics Engineers and BEST Robotics–Boosting Engineering, Science and Technology. In her free time, she enjoys baking, exercising, rock climbing, reading, playing video games and spending time outdoors.

Coley Stoller of Madison, SD will join Heartland June 6 as Customer Research Intern. An Accounting and Business Administration double-major at Augustana University in Sioux Falls, SD, Coley has experience tutoring students in accounting and assisting with document management. During her internship, she will be responsible for researching economic factors in Heartland’s customer communities as well as surrounding communities.

“I am looking forward to learning more about Heartland, including who and what they provide for,” said Coley. “I am excited to be challenged and help Heartland grow and improve communication with their customers.”

Interns-ColeyThe ultimate goal of Coley’s internship is to provide meaningful comparisons between Heartland’s customers and other communities to determine each customer’s strengths and weaknesses when it comes to growth and expansion. Based on research collected, an individualized economic development strategy will be created for each customer community.

“Coley’s accounting background make her a good fit for this project,” said Heartland Communications Manager Ann Hyland. “This research requires someone who is detail oriented and can look at a set of figures and make sense of them including drawing comparisons and noting correlations. This should provide some valuable information for our customers.”

Coley will be a junior at Augustana this fall with plans to eventually apply to the Masters program and graduate in May of 2019. After graduation, she hopes to work for one of the major public accounting firms in the area.

“I love the organizational aspect of accounting,” said Coley. “I love the business atmosphere and interacting with so many different types of people.”

Heartland applied for and was awarded funding through the American Public Power Association’s DEED (Demonstration of Energy & Efficiency Developments) Program for the internship. DEED awards scholarships to provide work experience to students at utilities and to support research projects that can be emulated by other utilities.

Coley is a member of the Augustana track team and participates in triple jump. She is also a member of FCA Huddle and is active in the volunteer group SALT–Serving and Learning Together. Through SALT she has been able to volunteer on campus and participate in numerous projects, such as helping out at a local homeless shelter, shopping for and providing holiday gifts for parents for their children through the Salvation Army, and creating scrapbooks for foster children. In her free time, she enjoys reading and spending time with friends, family and track teammates.
