Happens in the US, too. About twice a year I get someone on the door here in NYC who says they're from ConEd (they're not) and want me to know I'm missing out on a huge discount that is mentioned on my energy bill but is somehow opt-in. It's all nonsense, but what they actually want to you to do is sign up for an ESCO, i.e. a third-party energy provider. These ESCOs are always more expensive than ConEd (which already gets its energy supply from some efficient bidding market), and basically amount to a scam. ESCOs work in other countries such as Scandinavia, but not as implemented in NY.
