Live data updates as of

Kilowatt (kW):

A measure of electrical power equivalent to 1.34 horsepower or 1,000 watts. As an example, a typical toaster requires 800-1,400 watts to operate. Our chart displays megawatts, and one megawatt equals 1,000 kilowatts.

Kilowatt-hours (kWh) since April 2016:

A measure of electrical energy equivalent to 1.34 horsepower or 1,000 watts over a period of one hour. As an example, a 100-watt lightbulb operating for 10 hours would use one kilowatt-hour.

Plane of Array Irradiance (POAI):

A measure of the intensity of sunlight at the angle of the solar array (in the case of E.W. Brown solar, 20 degrees from horizontal) in watts per square meter.

Global Horizontal Irradiance (GHI):

A measure of the intensity of sunlight shining on a level surface in watts per square meter.

We began operating our E.W. Brown Solar Facility in 2016, providing power when the sun's shining bright. Since that time, we've learned a lot about how weather conditions in Kentucky affect our ability to produce solar energy at the facility. It is Kentucky's largest universal solar array and is part of our generation portfolio that works together to produce power with our coal, natural gas and hydroelectric fleet.

Here, you can see – in near real time – when our facility is generating electricity and how it performed in 2017.

Did you know


44,000 solar panels
on a fixed-tilt rack system make up our solar array.


50 acres
make up the solar facility’s footprint.


10 megawatts
can be produced by the facility when it’s at maximum capacity.


10 AM – 3 PM
are the best hours to produce the most solar energy in Kentucky


June is the sunniest
month to produce solar energy in Kentucky where our solar facility is located.


19,000 megawatt-hours
of energy can be produced annually during normal weather conditions.


1,500 homes
use about this same amount of energy annually if they're using 1,000 kilowatt-hours of energy each month.

In 2017, based on the weather conditions we experienced:

  • 17,366 megawatt-hours were produced.

  • 1,300 typical residential homes use about the same amount of energy generated by the facility in a single year.

  • 94 hours last year, the facility produced at its maximum capacity.

  • 2.3% of the year the facility operated at maximum capacity.

  • .05% of the total energy produced by our power plants last year came from our solar facility.


E.W. Brown Solar Facility historical data

By sharing this information, which we understand to be one of the largest and most comprehensive data sets on a commercial solar facility published, we want to help propel solar research and development and help those who are interested better understand the capabilities of solar energy in Kentucky.

Customer programs

In addition to operating our E.W. Brown solar facility, we support and want to help grow the use of solar energy in Kentucky. For customers who are interested in supporting solar energy at their home or business, we offer a variety of programs that can be tailored to our customers’ interests and needs.
