The PUC mandates that utilities negotiate for their default rate at times that were pre-set by each utility. PPL does so every 6 months, MetEd/First Energy does so quarterly. It is done by closed bid. PPL doesn’t shift customers to suppliers the PUC won’t allow it even when doing so would demonstrably save the consumer money. If you are using PPL as your default supplier you ignored their many warnings last year that rates were set to increase and to lock in a new rate. You can get as low as 9cents per Kwh shopping your rate.
