Live data updates as of
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.
Equivalent amount of power consumed by:
This number compares the amount of power being produced by the facility to the equivalent number of typical residential homes it could support at this moment.

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
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.
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.
