Cleaner, Greener Kentucky

Sustainability is a big part of everything we do. Here are a few of the ways we’re creating a cleaner, greener Kentucky:

Harnessing solar and hydroelectric power to generate clean energy for customers.
Leading developments and partnerships in cutting-edge carbon-capture technology and research.
Using sheep to keep vegetation in check.
Committing to economic development, which has helped generate nearly 100,000 jobs over the last decade.
Turning coal by-products into fertilizer.
Planting pollinator fields to help our environment.

And more.

Our sustainability commitment is far-reaching and includes:

We’ve pledged to electrify 10% of our transportation fleet by 2030 by replacing our end-of-lease light duty vehicles with a combination of fully electric vehicles or plug-in hybrids and outfitting our heavy-duty vehicles with plug-in idle mitigation units. We plan to have around 130 total electric vehicles, which will be a blend of light duty trucks and heavy-duty bucket trucks, which will also be much quieter while idling.

We recycle by-products from coal-fired generation and as of 2025, those efforts have created nearly $168 million in saving that have been passed onto customers.

We’ve already helped the city of Louisville to reduce its CO2 emissions by 10% and are increasingly adding more solar to further increase our existing renewable generation, which includes two, nearly 100-year-old hydro facilities. And, we’re continuing to explore additional opportunities to add more cost-effective renewable energy sources for our customers.

LG&E and KU Energy operates Kentucky's first and largest utility-scale energy storage system — a 1-megawatt, 2-megawatt-hour lithium-ion battery. The battery is co-located with E.W. Brown Solar, allowing the company to explore how batteries can improve the inherent intermittency of solar power.

The battery is operated 24/7, 365 days a year and is continuously collecting data — typically charging during the day when solar power is available and discharging at night. Battery use and availability has improved — from 54% in 2018 to 89% in 2020. The battery has collected twice as much data and stored almost twice as many megawatt-hours in 2020 as any other year.

Modes of Operation

The battery can be operated in several different modes. The Research and Development department most commonly operates the battery with Target State of Charge (SOC), which charges or discharges the battery to a certain percentage of capacity. The SOC% is programmed to fluctuate between 11% and 89%, as the top and bottom 10% of capacity are withheld for safety.

Other advanced functions are Auto Volt-Var, during which the battery supplies or absorbs reactive power in order to maintain grid voltage at a reference value, and Auto Frequency Watt, in which the battery rapidly charges or discharges to reduce grid frequency variation. The battery is also capable of performing solar-supporting functions during the day, including power smoothing and peak limiting.

Monitoring the Battery

The TRA department developed a real-time battery performance dashboard to monitor the system and maintain awareness of hundreds of conditions remotely. The department also developed an alarm system, capable of emailing and texting staff to alert them immediately about potential problems at the battery site. Employees in the department rotate responsibility for operating, monitoring, and maintaining the system, and all are capable of responding to problems at the site.

Academic Publications

Researchers at the University of Kentucky working with subject matter experts at LG&E and KU have collaborated on multiple research topics related to solar and battery energy storage systems. Over the past three years, nine academic papers and presentations based on data retrieved from the E.W. Brown Solar Dashboard and E.W. Brown 1-megawatt, 2-megawatt-hour battery have been published in multiple international journals, including the distinguished IEEE Transaction for Industry Applications.

The Ohio Falls Hydro Station, built in the 1920s within the McAlpine Locks and Dam, has been generating clean, renewable energy from the Ohio River for nearly a century. Originally powering much of Louisville, the plant underwent a major modernization completed in 2019, upgrading its eight generating units and technology to boost efficiency and safety. Today, it continues to deliver low-cost, environmentally friendly electricity while preserving its historic character.
