Quick answers
- How much can I save by switching electricity suppliers?
In deregulated states, any licensed supplier rate below your utility's default rate (called the Price to Compare in Pennsylvania, or "default service rate" in other markets) saves you money on the generation portion of your bill, every month. Actual savings depend on your specific utility and the offers available in your area.
Read: Pennsylvania Price to Compare Explained- Is switching electricity suppliers safe? Will my power get interrupted?
Switching is safe and there's no interruption. Your local utility still delivers your power over the same wires and handles all outages and maintenance, regardless of which supplier you choose. Only the generation charge on your bill changes.
Read: How to Switch Suppliers in PA- What is the Price to Compare?
In Pennsylvania, the Price to Compare is your utility's default rate for the generation portion of your bill — the benchmark to beat. Other deregulated states have similar concepts under different names (e.g., "default service rate," "standard offer").
Read: Pennsylvania Price to Compare Explained- Are green energy plans really renewable?
Most green plans fund renewable generation through Renewable Energy Credits (RECs). Your specific electrons don't change, but the overall grid mix shifts toward renewables. State renewable standards (like Pennsylvania's AEPS) shape what counts as renewable.
Read: Green Energy Plans in Pennsylvania- How long does it take to switch electricity suppliers?
Enrollment takes a few minutes online. The actual switch completes in 1-2 billing cycles with no service interruption — the timing is consistent across most deregulated states.
