Many forward-looking cities, companies and institutions have begun to pursue 24/7 carbon-free energy (CFE). As momentum builds, new 24/7 CFE supply offerings have emerged. But what do these 24/7 CFE supply products look like? How do they work? How were they developed? And how much demand is there for them?

6. UTILITY 24/7 CFE OFFERINGS FOR LARGE BUYERS
24/7 CFE Utility Solutions with Institute for Electric Innovation (IEI)
• Workshops and dialog with a group of utilities and customers on designing 24/7 CFE
utility offerings
• Goals of workshops are to understand:
– customer demand for hourly 100% CFE solutions;
– the attributes of these solutions that matter most to customers;
– key challenges with scaling CFE solutions to a wider set of customers;
– possible designs of CFE offerings that electric companies could provide to; and
– the customer’s need for easy access to specific customer and grid hourly data to
implement and verify 24/7 solutions.

Georgia Power 2022 IRP Projected Capacity Mix
These capacity mixes reflect nameplate capacity for renewable resources, program capacities for demand-side options (“DSOs”), and designated/demonstrated capacity for the remaining
fuel types. A portion of the renewable generation capacity included in these charts includes capacity where the renewable generator retains the related Renewable Energy Credits (“RECs”).
