Renewable Energy

We believe that renewable resources are our past, present and future. From generating water-driven hydroelectric power at home to investing in wind farms and solar energy projects, we are a leader in promoting the tremendous value of natural resources.

For these reasons, we started the Renewable Energy Credit (REC) program. This program allows customers to collaborate with us to invest together in our clean energy future. Customers can purchase Renewable Energy Certificates (RECs) that are associated with energy generated from renewable sources.

What is the Renewable Energy Credit (REC) program?

Renewable Energy Certificates (RECs) represent the property rights to the environmental, social and other non-power attributes of renewable electricity generation. RECs are issued when one megawatt-hour (MWh) of electricity is generated and delivered to the electricity grid from a renewable energy resource.

You can purchase a REC for as little as $1.25 a month.

RECs can be used to substantiate renewable energy generation and use claims. They are supported by several different levels of government, regional electricity transmission authorities, nongovernmental organizations (NGOs), and trade associations, as well as in U.S. case law.

RECs include several data attributes, including:

  • Certificate data

  • Certificate type

  • Tracking system ID

  • Renewable fuel type

  • Renewable facility location

  • Nameplate capacity of project

  • Project name

  • Project vintage (build date)

  • Certificate (generation) vintage

  • Certificate unique identification number

  • Utility to which project is interconnected

  • Eligibility for certification or RPS

  • Emissions rate of the renewable resource

More information about RECs is available from the EPA’s website: https://www.epa.gov/greenpower/renewable-energy-certificates-recs.

Biomass Energy

Plants grow by converting solar energy into “biomass,” and some forms of biomass are more useful than others in storing and releasing that energy. Biomass is considered “carbon neutral” - meaning that carbon dioxide emissions from burning biomass are offset by the CO2 that was absorbed by the biomass as it grew.

For more than a decade, we have researched biomass – from wood chips to switchgrass – at almost half a dozen of our generation facilities. We are also partnering with a Westervelt Company in Moundville to produce more biomass energy. We have the flexibility to either deliver the energy to our customers or sell the energy or the associated renewable energy credits to third parties.

Wind Energy

We are a leading purchaser among southeast utilities of energy from out-of-state wind farms. The company has agreements with Chisholm View Wind Project in Oklahoma and Buffalo Dunes Wind Project in Kansas for enough energy to power more than 100,000 homes. Under both 20-year contracts, we have the flexibility to use generated wind energy to serve customers and retire the associated renewable energy credits (RECs) or sell the energy and RECs to others, either separately or bundled together.
