Utility Collaboration - LG&E and KU

Joint Research and Academic Journal Technical Papers

Researchers from LG&E and KU from PEIK at UK are collaborating on projects with a focus on the integration of distributed energy resources, such as utility scale PV solar power plants, in the generation and transmission electric power systems. Other topics include smart grids and electric power distribution systems, and artificial intelligence methods for load forecast.

Joint publications include an IEEE Industry Applications Society Renewable and Sustainable Energy Conversion Committee paper award winner. Some of the recent joint papers from academic technical journals are available in authors’ manuscript PDF versions from UKnowledge online database at UK or directly from the following weblinks:

Solar Photovoltaic Facility Resources and Online Data

LG&E and KU owns and maintains the E.W. Brown Solar Facility in Harrodsburg, KY, which covers 50 acres and includes 44,000 solar PV panels with a total 10 MW capacity. As an example, in 2020, this power plant facility generated the same amount of energy annually as used by 1,375 typical homes. The facility can be viewed via a live stream.

The solar PV power generation data, which has also been used for research studies, is available for general access via the following weblinks:

Habitat for Humanity – a Kentucky Study

LG&E and KU and PEIK at UK researchers collaborated on the final data analysis for an annual study that involved ten Habitat for Humanity households, which each received 18 shares of solar PV panels with a capacity of 4.50 kW DC, 3.78 kW AC. The shares were provided with no cost to the participants through LG&E and KU’s Solar Share Community Solar Program. The solar generation was used to reduce the electricity bills for the households by an average of $27.94 per month and lower their equivalent emissions by 88.7%. The summer months provided the most monetary benefit on average, but also the widest range in value to participants. Winter had the lowest solar PV generation and lowest average monetary benefit for the participants. More details are available in a brief report.

Teaching and Outreach

PEIK has an ongoing close collaboration with Louisville Gas and Electric and Kentucky Utilities (LG&E and KU) on teaching activities, including classes with field visits to utility facilities, lectures, and seminars by LG&E and KU technical experts. The course Efficient and Renewable Power Systems Operations, which is typically offered in the spring, comprises lectures on campus in the first part of the semester, followed by on site instruction at the EW Brown power plant, including the coal, hydro, natural gas, the solar PV, and the battery energy storage facilities. The experience contributes directly to the students' preparation for work in industry and the power utility sector.

Further collaboration between the two organizations includes joint participation at public events, such as the College of Engineering E-Day, which typically attracts more than 3,000 visitors from around the state on the UK campus. The PEIK Distinguished Speaker Seminar Series that takes place during the academic year, regularly includes talks from LG&E and KU managers and subject matter experts. Guest lectures are held as part of specialty and large classes, such as EGR 240 – Global Energy Issues, to provide the industrial and utility perspective to the academic curriculum. The example lecture notes are for “Kentucky’s Clean Energy Successes, Opportunities, and Challenges”

The UK College of Engineering annually issues many scholarships to undergraduate students with a strong interest in power and energy, as demonstrated, for example, by the participation in the PEIK certificate program and activities. These scholarships are made possible by an endowment established years ago through E.On on behalf of Kentucky Utilities. The recipients receive between $2,000 and $3,000 annually and may also be granted an additional $2,000 for use on a power and energy related study abroad trip during the school year or the following summer.
