Green Energy program

Join our Green Energy program to make a difference

The LG&E and KU Green Energy program is voluntary. By participating, you are taking action to expand the generation capacity of renewable power on the regional electric grid that serves Kentucky.

How it works

You purchase Green Energy blocks

You purchase blocks of Green Energy each month, from LG&E and KU.

We purchase Renewable Energy Certificates on your behalf

We use the dollar value of your blocks to purchase Renewable Energy Certificates (RECs) from regional energy sources like solar, wind and biomass. The REC’s are retired on your behalf. Learn more on our REC purchases page.

Help support Green Energy

You directly support the growth and long-term viability of regional renewable energy operators and the broader renewable energy industry.

Green Energy block calculators

The Green Energy calculator will help you decide how many “blocks” to purchase per month by calculating the environmental benefit of your purchase in terms of carbon emissions reduced, at any level you choose.  

The Green Energy program provides an easy way for you to obtain RECs and their associated benefits, as well as show your support for renewable generators and the industry.

What is a Green Energy Block?

The purchase of a block ensures exclusive ownership of the environmental and social benefits of the underlying electricity. When the Green Energy program purchases RECs on your behalf, only you can claim their associated benefits. Residential and small business customers pay $5 per block and large commercial and industrial customers pay $13 per block. Pricing of RECs can fluctuate with market pricing, however below are the annual averages during the 2021 calendar year:

  • Every $5 contribution to the Green Energy program purchased 1 block, which is roughly .9 RECs or 902 kWh of renewable (“Green”) energy.
  • Every $13 contribution purchased 1 block, which is roughly 2.63 RECs or 2,628 kWh of renewable (“Green”) energy.
