An Offsite Renewable Energy Alternative

As more businesses commit to meeting renewable energy goals, many are realizing that the renewable energy options available to them are difficult to implement, carry unwanted risks, and don’t make a strong enough sustainability statement.

Constellation’s CORe products combine location-specific renewable energy purchases and renewable energy certificates (RECs) with a physical, load-following, energy supply contract.

If your business is looking for an even more impactful renewable option, CORe+ supports the development of new build renewable assets through your retail power contract.

Meeting Renewable Energy Goals

Customers can achieve renewable goals and make a local offsite renewable energy purchase with a retail power supply contract through our CORe product. With CORe, your company can show its customers, shareholders, communities and employees the specific facility on the same regional power grid from which it purchases its renewable energy. Energy and RECs from the local generation facility can be procured as a part of your retail supply contract. CORe products make buying your renewable energy easier.

Customer Benefits CORe CORe+

Easy Sustainability and Greenhouse Gas Claims 

Constellation will purchase and retire the volume of RECs generated by a specified renewable generation facility equal to the amount of renewable energy you purchased.


Location Specificity

Your company can report its commitment to renewable energy by showing the specific facility that you are purchasing energy from. You can also show that it is delivering renewable energy to your regional power grid.

Risk-Managed Renewable Supply

CORe products include physical, load-following energy supply inclusive of all applicable transmission, ancillary services and other costs as required for generation supply in your market. You get a single, renewable energy price for every spin of the meter.

Simple Retail Contracting

Achieve your sustainable energy goals through the simplicity of your retail power agreement. Unlike an offsite power purchase agreement (PPA), there is no need to reconcile the renewable energy contract with a separate utility or supplier contract, and you're not limited to a complex contract for difference (CfD) settlement.

Short Contract Terms

Flexibility to purchase in short-term contracts and/or smaller volume sizes.


Support New Asset Development

Support the development of new renewable facilities in your regional grid with CORe+.
