Your account number is the only thing a company needs to switch you to an alternate energy provider. All you need to do is show them a copy of your bill (or tell them the number over the phone) and they will switch you against your will. At that point your supply charges (which pays for poles and power lines into your house) still goes to PSE&G but rather than choose the cheapest available power generator, you now buy your power from whatever company you switch to.

People sometimes do this because they want their power bill to go toward some kind of environmentally friendly company but rarely will switching ever save you money. If someone cold calls or approaches you, it's a scam.

They try and get you to sign up with an energy company that purports to be much cheaper than PSEG. And they are... for the first month or two, and then the rates jump up, but you're locked into a contract and are stuck paying more.

In addition to what was said below- they are dishonest from the start. Instead of introducing themselves as an Arcadia employee and that they’re selling solar energy, they start off by asking to see your PSEG bill with this laminated paper that says PSEG on it- so they try to come off as if they are PSEG. And then they give you a completely made up a reason for wanting to see your actual bill. Their approach is dishonest and makes zero mention of who they are and what they sell. It should be illegal for them to switch a customer’s energy source provider without permission. The only way PSEG combats it is by sending you a notice that the energy was switched and you can switch it back.
